Spin (cue Sports)

The following is a glossary of traditional English-language terms used in the three overarching cue sports disciplines: '' carom billiards'' referring to the various games played on a billiard table without ; ''pool'', which denotes a host of games played on a table with six pockets; and ''snooker'', played on a large pocket table, and which has a sport culture unto itself distinct from pool. There are also games such as English billiards that include aspects of multiple disciplines.

Definitions and language

The term ' is sometimes used to refer to all of the cue sports, to a specific class of them, or to specific ones such as English billiards; this article uses the term in its most generic sense unless otherwise noted.

The labels "British" and " UK" as applied to entries in this glossary refer to terms originating in the UK and also used in countries that were fairly recently part of the British Empire and/or are part of the Commonwealth of Nations, as opposed to US (and, often, Canadian) terminology. The terms "American" or "US" as applied here refer generally to North American usage. However, due to the predominance of US-originating terminology in most internationally competitive pool (as opposed to snooker), US terms are also common in the pool context in other countries in which English is at least a minority language, and US (and borrowed French) terms predominate in carom billiards. Similarly, British terms predominate in the world of snooker, English billiards, and blackball, regardless of the players' nationalities.

The term "blackball" is used in this glossary to refer to both blackball and eight-ball pool as played in the UK, as a shorthand. Blackball was chosen because it is less ambiguous ("eight-ball pool" is too easily confused with the international standardized "eight-ball"), and blackball is globally standardized by an International Olympic Committee-recognized governing body, the World Pool-Billiard Association (WPA); meanwhile, its ancestor, eight-ball pool, is largely a folk game, like North American , and to the extent that its rules have been codified, they have been done so by competing authorities with different rulesets. (For the same reason, the glossary's information on eight-ball, nine-ball, and ten-ball draws principally on the stable WPA rules, because there are many competing amateur leagues and even professional tours with divergent rules for these games.)

Foreign-language terms are generally not within the scope of this list, unless they have become an integral part of billiards terminology in English (e.g. ), or they are crucial to meaningful discussion of a game not widely known in the English-speaking world.

With one being (, British: ) to a and the second object ball just slightly away from the cushion, the is gently grazed across the face of both balls, freezing the away ball to the rail and moving the frozen ball away the same distance its partner was previously, in an identical but reversed configuration, in position to be struck again by the cue ball from the opposite side to repeat this pattern, back and forth. ''Compare .''

1.  An area defined on a billiard table by one or more . In the eponymous game of balkline billiards, there are eight balks defined by perpendicular balklines, in which only a set number of may be scored before at least one ball must leave the area.. In the earlier (and short-lived) " champions' game", there were four triangular balks, one at each corner, defined by single diagonal balklines. ''Not to be confused with , but see second definition.''

2.  An area defined on a billiard table, in games such as pool, snooker, English billiards and bagatelle, by a single (drawn or imaginary) that runs across the table near the () end; exactly where depends upon table type and size. This balk is where the cue ball is placed in for lead, for making the opening shot, and sometimes for other purposes, depending upon the game. This usage of "balk" is strictly technical, and rarely used in practice. In pool, this area is called the and is divided from the rest of the table by the , while in snooker, English billiards and blackball it is the somewhat differently sized and delimited , defined by the . On baulk tables, which have inside baulk, and on pool tables with a in the kitchen, the actual area from which to shoot is even smaller than the baulk or kitchen, respectively – a balk within the balk.

1.  A line drawn horizontally from a point on a billiard table's to the corresponding point on the opposite rail, thus defining a region (a ). In the eponymous balkline billiards there are four balklines, drawn parallel to and typically 14 or 18 inches from the cushions of the table, dividing it into nine compartments or divisions, of which the outside eight are the balks, in which only a set number of caroms may be scored before at least one ball must leave the area. ''Not to be confused with , though the concepts and etymologies are related. See , second definition.''

2.  Formerly, in " the champions' game", a line drawn diagonally from a to a at the corners of the table, defining a triangular at each.

Usually only available to a player when the opposing player has committed some type of under a particular game's rules (cf. the free throw in basketball by way of comparison). ''See also for the snooker definition.'' A common variation, used in games such as straight pool and often in , is ball-in-hand "behind the head string", also "behind the line" or "from the kitchen", meaning the ball-in-hand option is restricted to placement anywhere behind the , i.e., in the area of the table known as the .

Any legally strikeable ball on the table in snooker and generally British terminology. For example, in blackball, if a player is playing , any yellow ball (or any solid, from 1 to 7, if using a solids-and-stripes ball set) can be the ball-on until they are all , in which case the 8 ball is the ball-on. In snooker, at the beginning of a player's turn, unless all are already potted, any can be the ball-on. ''Compare .''

3.  A designed exclusively for storing balls

A collection bin mounted below the foot end of a table, to which balls potted in any pocket will return by means of gravity-assisted gutters or troughs running from each pocket opening to the bin; these are the ball-return mechanism, which may be internal to the table or an external gutter system. Ball returns have been in use since at least the 1700s. Pockets that simply collect balls are known as . A table without a ball return may be called a "drop pocket table", while a table featuring a ball return may be called a "gully table". Coin-operated have ball-return mechanisms that separate the from the so that the object balls are captured when pocketed until the game ends, then released when paid for again, while the cue ball is continually returned for continued play after . This type of table can use a variety of methods to distinguish the cue ball from object balls including the , the dense ceramic "" and the oversized "" ball. Ball return mechanisms have also been devised that use a smaller, lighter cue ball, instead of a magnetic or heavier one. There are tables that use optical sensors to distinguish a standard cue ball from object balls. Some of them are also setup to return the 8 ball as well, so that pocketing it on the break does not end the game.

A derogatory term for a recreational or beginning player who "bangs" the balls without any thought for nor attempt to control the ; also a reference to the predilection of beginners to often hit the cue ball far harder than necessary. ''Compare British .''

''Also bank.'' Shot in which an is driven to one or more rails prior to being (or in some contexts, prior to reaching its intended target; not necessarily a pocket). Sometimes "bank" is conflated to refer to as well, and in the UK it is often called a double.

A rule variant common in versions of eight-ball, in which the 8-ball must be pocketed on a (generally this would either be accomplished via a bank shot proper or a ); shooting the 8 straight in is a loss of game. Players may agree before the game begins to invoke this rule, or one player may challenge another player (who might accept or refuse) to conclude the game in this manner after it is already under way. Playing bank-the-8 can be considered rude if many other players are waiting to use the table, since it often makes the game last considerably longer. Often on bar tables three es while shooting for the 8 determines a loss. The same with last-pocket.

''Also bar league player.''
A player that predominantly plays in bars/ pubs, or is in a bar-based pool league. Often used pejoratively by pool hall players to refer to a perceived lesser skill level of such players. ''See also , .''

Pool, almost always a variant of eight-ball, that is played by on a . Bar pool has rules that vary from region to region, sometimes even from venue to venue in the same city, especially in the U.S. Wise players thus ensure understanding of and agreement to the rules before engaging in a under bar rules. Typical differences between bar pool and tournament eight-ball are the lack of after a , the elimination of a number of fouls, and (with numbered ball sets) the requirement that most aspects of a shot be (including and other to be contacted) not just the and . Bar pool has evolved into this "nitpicky" version principally to make the games last longer, since bar pool is typically played on coin-operated tables that cost money per-game rather than per-hour. Competitive league pool played on bar tables, however, usually uses international, national or local/regional league rules, and is not what is usually meant by "bar pool". ''Not to be confused with the game of bar billiards.''

A distinctive size of pool table found in bars, pubs, or taverns as well as venues such as family entertainment centers, arcades and bowling alleys. These are smaller than the full-size tables found in pool halls. While typical professional and competition tables are , bar tables are typically . In bars they are almost always coin-operated. Another distinguishing factor is the cue ball; these tables capture pocketed to remove them from play, but selectively return a cue ball. The cue balls historically were differently sized or of different density so they could be mechanically separated. Because this changes the mechanics of the cue ball, these cue balls do not play as competition cue balls, and they are therefore deprecated by aficionados. However, modern bar tables typically make use of a magnetic layer inside a regulation size and weight cue ball paired with a magnet mechanism within the table's system that separates out the cue ball without requiring cue ball characteristics that affect play. Systems that use optical sensors to distinguish the cue ball have also been introduced. Pool hall players complain also that the used on bar tables is often greatly inferior (in particular that it is "slow" and that does not "take" enough), and often find that the are not as responsive as they are used to.

''Also baulk area, baulk end.''

''Also baulk-line.''.
A straight line drawn 29 inches (73.66 cm) from the face of the on a standard 6 × 12 foot snooker table. Its positioning varies on other sizes of tables. Baulk lines may also be drawn on English billiards tables, and even British-style pool tables. The baulk line is an integral part of . The baulk line's position is always determined by measurement from the baulk cushion, in contrast to the similar but different , the position of which is determined by the . ''Not to be confused with .''

The of the table consists of the bed except where the cushion overhangs the bed, i.e. it is all of the bed between the cushion . Quality beds are made of smooth-ground slate, though very cheap tables may use particle board or plywood. The earliest beds were simply the surfaces of the wooden tables on which the game was played.

In eight-ball, to be shooting the striped () of balls (9 through 15); "you're big, remember", "you're big balls" or "I've got the big ones". ''Compare , , , ; contrast .'' ''Not to be confused with the carom billiards concept of a .''

A carom billiards metaphor, it refers to an object ball positioned and being approached in such a manner that a near miss will rebound off a cushion and still score. It is ''as if'' the ball were larger than normal, making it easier to contact. Normally a ball near a rail is a big ball, but only if being approached from an angle and if all the prerequisite rails have already been contacted.
Not to be confused with the eight-ball term "the big balls", referring to the higher-numbered striped balls. In older British usage the concept was referred to as "large ball". ''See also "".''

A pool and occasionally snooker term (inherited from carom billiards by way of "", above), it is a metaphor for a shot that is very difficult to miss pocketing for any of a number of reasons, most commonly: either the object ball is positioned such that a near miss on one side of it will likely cause the cue ball to rebound off the rail into the object ball and pocket it anyway; or another ball is positioned such that if the target ball does not go straight in, it is still likely to go in off the other ball in a . It is ''as if'' the pocket, for this one shot, had become larger. The term can also refer to the angle of shot toward a pocket, especially a side pocket; the pocket is said to be "bigger", for example, on a shot that is only a 5-degree angle away from straight on, than on a 45-degree angle shot which is much more likely to hit one of the cushion points and bounce away.

1.  Any shot in which the is off an to strike another object ball (with or without contacting cushions in the interim).

2.  In certain carom billiards games such as three-cushion, a successful attempt at making a ''scoring'' billiard shot under the rules for that game (such as contacting three cushions with the cue ball while executing the billiard). A failed attempt at scoring would, in this context, not be called "a billiard" by players of such games even if it satisfied the first, more general definition..

1.  A person who records the for each player during a game;

1.  In the US, Canada and in many different countries and languages (under various spellings) as well as historically, generally refers to all cue sports;

3.  In British terminology, chiefly refers to the game known in the rest of the world as English billiards.

''Also pool spectacles, snooker specs, etc.''
Eyeglasses specially made for cue sports, with tall lenses, set unusually high, so that when the head is lowered over the cue stick for aiming, with the nose pointing downward, the eyes can still look through the lenses instead of over them. They are especially popular among snooker players (notably, 1985 World Champion Dennis Taylor).

''Chiefly American:'' In pool games, when a player the , at least one ball on the break, and commences to the remaining object balls without the opponent getting a at the table. Hyphenated when used as an adjective or compound noun instead of a verbal phrase. ''See also , .''

In straight pool, the last object ball left on a table before the remaining fourteen balls must be racked so the player at the table may continue their run. It is called the "break ball" because it is common for players to try to leave this ball in such a position that they may easily pot it and billiard off of it to break open the rack of fourteen balls and continue their run.

In European Pocket Billiard Federation (EPBF) nine-ball, the break box is a zone in the "" of the (British: ) of the table, from which the must be taken with the . The break box consists of the middle 50% of the kitchen area, delimited latitudinally by the (British: ) and (not the ), and longitudinally by two parallel lines drawn (on the cloth, or more often imaginarily) from the head rail that are closest to the , out to the head string ''(see illustration to the right)'' on either side. This departure from WPA World Standardised Rules defeats the common break-from-the-side-rail technique for pocketing the 9 ball to win the game on the break; while 9 ball breaks are still possible, they are much more difficult under this rule. This EPBF Euro-Tour requirement was added in 2008 to the Europe vs. US all-star team event, the Mosconi Cup, but has not otherwise been seen much by non-Europeans

C

A players' auction at a pool tournament. Each player is called and players and spectators bid on the player. The highest bidder(s) pays their bid to the calcutta, and by doing so invest in that player's success. If a player wins or places in the tournament, those who "bought" the player receive a percentage of the total calcutta payout, usually tracking the percentage payout of the tournament prize fund. Typically, players have the option of purchasing half of themselves when the high bid is won by a third party. Like and , usually not capitalized.

Any instance of a player having to say what they are about to do. For example, in straight pool a player must ''call'' the pocket in which a ball is intended to be potted. More formal terms, used in rule books and instructional materials, include and . ''Contrast , .''

Applies specifically to games that enforce "/call-safe" rules, which require the player to either call the ball and pocket, or call a on every shot. After a legal shot, where a called ball is not pocketed as designated, the incoming player has the option to pass the shot back to the player who missed the called shot. If a player calls "safe", then after a legal shot, the incoming player must accept the next shot, and may not pass the shot back to the player who called "safe". A call-shot/call-safe nine-ball example: Player A calls the , the 3 ball in this case, in the corner pocket but misses the shot. The rolls down table and comes to rest behind the 5 ball leaving no clear path to the 3 ball for the incoming player B. Since player A did not call "safe", incoming player B may elect to pass the shot back to player A (who must shoot).

Describes any game in which during normal play a player must call the ball to be hit and the intended pocket; "eight-ball is a call-shot game." Sometimes referred to as "call dpocket", " rules", etc., to distinguish it from the common North American practice of requiring every ''aspect'' of shots to be called, such as , , and to be contacted (this is sometimes also ambiguously referred to as "call-shot", but more accurately termed "call-everything" or "call-it-all"). Commonly in bar rules terminology, call-shot indicates how the shot will be made as compared to call-pocket which means simply that the ball must go into that pocket, details unnecessary. Though games with called shots technically require all shots to be called, obvious shots are seldom actually called, though such implied called shots must still be made. ''See also .''

The pocket designated by a player to which a ball is to be shot.

British/Australian and sometimes Canadian term for . Formerly (19th century) sometimes spelled ''canon''.

1.  The red in carom billiards games. The term is thought to be derived from an orange-coloured, tropical Asian fruit, called a ''carambola'' in English, Spanish, and several other languages, in turn from in the Marathi language of India.

2.  A general-purpose term for carom billiards games.

3.  (Obsolete.) Alternative name for the game of straight rail.

4.  A shot.

''Short for .''

1.  ''Carom'' came into use in the 1860s and is a shortening of ''carambola'', which was earlier used to describe the red object ball used in many billiards games. In modern usage, the most general meaning of the word refers to any type of strike and rebound, (a ) off a cushion or especially a ball.

2.  More specifically, short for a ''carom shot'', a in British terminology, in which a point is scored in carom billiards games by careening the cue ball into the two object balls.

3.  In pocket games as a general class, ''carom'' or ''carom shot'' is sometimes used more loosely, between the above two definitions, to refer to clipping an object ball with the cue ball to attempt to send either or both to desirable locations, not necessarily scoring in the process. In games in which pocketing the cue ball is a goal (e.g. Russian pyramid), ''carom'' can refer to sending the cue ball into a pocket after contacting an object ball (called a in English billiards, it nevertheless scores points; but it is a foul in snooker, called an , and in pool, called a ).

4.  Short for carom billiards, as in "I do better at carom than at pool." Sometimes pluralized in this sense as ''caroms''.

One of the main classes of cue sports, possibly the oldest, and certainly the dominant competitive form until well into the 20th century. It is played on a table without pockets, and scoring is generally done by driving a into contact with one , then having the cue ball contact one or more before contacting another object ball; however, there are numerous variations, some of which involve additional objects, such as upright as targets or s. Carom balls are usually larger than pool balls, and most often supplied in sets of three, though some games such as yotsudama require four. Historically the most popular carom games in the modern era were straight rail and cushion caroms, followed by balkline billiards, in turn supplanted by three-cushion billiards which remains a major competitive world sport and is the dominant cue sport in many countries. Some games, such as English billiards, are hybrids between carom and pocket billiards.

Carrom is a table-top game of India, sometimes played with a small cue stick though more often with the fingers, in which small disks are slid on a game board to knock other disks into pockets cut into the corners of the board. It is ancestral to several other games, including novuss, pichenotte, pitchnut, crokinole, and Chapayev. Its historical relationship to billiards games is unclear.

A set of pool balls divided into s (s) of red and yellow balls (typically unnumbered, aside from the black 8-ball) instead of stripes and solids. Most often used for the game of blackball (British-style eightball pool).

''Also century break.''
In snooker, English billiards and other British usage, a of 100 points or more, which requires at least 25 balls consecutively, in snooker, but can be earned via a combination of scoring techniques in English billiards, etc. A century also means scoring 100+ points in a single turn in straight pool. A century of centuries is the achievement of 100 or more century breaks in a career, a feat few players have performed to date. ''See also .''

A powdered substance placed on a cue's to increase its friction and thereby decrease slippage between the tip and . Cue "chalk" is not chalk (calcium carbonate), but a compound of silica and aluminium oxide. Chalk is sold in compressed, dyed (commonly blue) cubes wrapped on five sides with a paper label, and is applied (properly) in a manner similar to lipstick on the mouth. Chalk is essential to shots involving ; failure to use it frequently during a game is likely to lead to . Modern cue chalk was co-invented by pro player William A. Spinks and engineer William Hoskins. ''See also , often incorrectly referred to as "".''

The inability of some players to stop gambling once they have lost money because they "have" to get their money back.

To aim at an object ball such that it will enter one side or the other, rather than the center, of a pocket (and possibly striking the of the pocket then rebounding into the pocket). This permits the cue ball to strike the object ball at a different than the most obvious one. Cheating the pocket is employed for , to allow a ball to pass another partially obscuring the path to the pocket, and to prevent on dead-straight shots in cases where draw is not desirable (or may not be dependable, e.g. because of distance from the pocket or ). The amount of pocket cheatability available varies widely by game, due to equipment differences. Pool has wide and thus very "cheatable" pockets, while snooker and Russian pyramid have pockets barely wide enough to admit a ball and therefore little room for error or for pocket-cheating.

''Also checkside or check.'' A type of imparted to the to make it rebound off a at a shallower angle than it would if the spin had not been used. Normally played when the natural angle is no good to the player for the next shot.

Sometimes known as a "Chesney Allen", a slight indentation in the table's slate which can add behavioral aspects to any ball passing over it. Tables containing a chesney are legal for match play, but are generally avoided by serious and professional players.

A situation where the is directly in front of another ball in the line of the shot such that the player is by it, having to over it awkwardly with the likelihood of a looming if the object ball is inadvertently touched. The term is most common in the game of snooker but is also used in US parlance.

Known as a in British terminology.
A type of used in carom billiards games. With one object ball (British: ) to a and the second object ball a few inches away from the cushion, the cue ball is gently rebounded off the frozen ball, not moving it, but with just enough speed to meet the other object ball, which rocks in place but does not change position. Developed to thwart the restrictions emplaced by the .

1.  Sufficient space to legally execute a shot, without a (), e.g. from striking a . Usage examples: "I wonder if I really have clearance for the 8"; "I bet you can't clear the 6 and make that shot." Can apply to any shot situation, including vertically: "a long that has to clear three balls."

2.  In snooker and British blackball, the successful of all object in a single . A player is said to have "cleared up" or to have "cleared the table". Also, if a snooker player compiles a consisting of all 15 with , then the colours in sequence, this is known as a "". ''Compare .''

3.  A type of maneuver, the or , in which the ball is used to move one or more balls out of the way (directly or some by subsequent impact) then continue on to a desired destination. E.g., in a game of nine-ball, if the 1 and the 7 were clustered together along a cushion with the 9 behind them near a pocket, and the cue ball could strike the 1 full face with a result of the 1 heading off the 7 toward the top rail and the 7 rebounding quickly across the table from the cushion, the cue ball, with could retain enough post-impact momentum to continue forward and pocket the 9 as long as both the 1 and the 7 were ''cleared'' out the way first. In a game like eight-ball, a clearance shot might also be used at the end of an inning to move some problem balls that are blocking an otherwise easy , and leave the cue ball in a position, in hopes of having a better layout to work with in the next inning. shots are among the most common clearance approaches, especially for very short distances of intended cue ball travel past the initial contact. ''"Clearance" is essentially the opposite of "", though the latter term is largely confined to carom billiards.''

Phenomenon in which two balls, (usually the and an ) have some foreign material – typically often residual cue-tip or dirt picked up from unbrushed – between the balls at the , resulting in the struck object ball being thrown offline from the expected trajectory, and often also affecting the post-impact behavior of the cue ball. Cling is an exaggerated form of , caused by momentary but unusually gripping friction imparted by the chalk or other residue. ''Also known as , or in the UK, (sense 2).'' A typical precaution against cling is to ask for the cue ball and/or object ball to be cleaned by the referee in order to remove chalk that is already on the ball prior to the shot; and (including in non-refereed games) players cleaning the cue ball personally after gaining . The table cloth can also be brushed between matches. When conditions seem ripe for clings (e.g. visibly dirty balls) some skilled players resort to pre-emptively using (and compensating for) , a general anti-throw technique. However, no precaution can ward against cling resulting from chalk transferred from the cue tip to the cue ball during a single shot. Coincidental cling can therefore cause unpredictable play and occasionally lead to rudimentary shots being missed at even the highest levels of the game. "Cling" (and derived words like "clung", "clinger", "clinging", etc.) may be used as a mass noun, less commonly as a count noun, as a verb, and rarely as an adjective ("cling is annoying", "two clings in one frame", "they clung", "unintentional cling shot", respectively). ''See for snooker-specific notes.'' ''See also , sense 2.''

''Also loop bridge.''
A bridge formed by the hand where a finger (normally the index finger) is curved over the cue stick and the other fingers are spread on the cloth providing solid support for the cue stick's direction. A closed bridge is less common in snooker play than in other games. ''Compare .''

The baize cloth covering the tables playing surface and rails, usually made from wool or a wool-nylon blend. In use since the 15th century, cloth is traditionally green-coloured, chosen for its evocation of grass. Sometimes cloth is improperly referred to as "felt." The properties of the cloth used to cover a table, as well as environmental conditions that can affect it—notably humidity, the degree it has been stretched when installed, and its level of cleanness—have a profound effect on play..

A type of shot used in English billiards in which two coloured balls are positioned on either side of the mouth of a snooker table pocket but not touching and, thus placed, can be successively contacted and scored off over and over by the cue ball without moving them. The cradle cannon's first known use was by Walter Lovejoy in 1907. The unofficial record using the shot is held by Tom Reece who in 1907, over the course of a month, scored 499,135 points using the cradle cannon before stopping without missing. This feat prompted the Billiards Association to outlaw the shot. The official record is held by William Cook with 42,746 points scored. ''Compare .''

The elastic bumpers mounted on all s of a billiards table, usually made from rubber or synthetic rubber, off which the balls rebound. Before the advent of vulcanized rubber manufacturing in the mid-19th century, cushions of early billiard tables were often simply cloth stuffed with straw, cotton, or other fibers; they were not very elastic, but simply quieter than bare wooden boards. The existence of cushions and rails dates to the era of outdoor ground billiards, the courts for which were often bounded by short wicker or wood fences, sometimes padded.

2.  A ball that has been used for some time, with a dirty surface, as opposed to a slick new (or highly polished used) ball. A dead ball will transfer more spin to other balls it comes into contact with, and not be as on the cloth. Even angles may be affected because of the or (British: ) effect, and professional players often ask a referee to clean a ball, mid-game. Others may actually be more used to dead balls and prefer them.

''Also cushion face.''
The protrusion of the playing edge of the from the over the of the table. The furthest-protruding point of the face is known as the of the cushion. The of the table is the space between the faces (technically, the noses) of the cushions.

The facings of a are the portions of the rail s that line the of the pocket. Facings vary widely by game. Pool facings are flat and angled rather wide, on pockets notably larger than the balls, to act much like the backboard in basketball, in that a shot can be directed into the facing to cause it to angle off the facing into the pocket. They are reinforced with plastic shims between the cushion rubber and the , to reduce wear and tear. Snooker facings are curved and not angled, providing a smooth transition between the rails and the pockets, which are not much wider than the balls, thus preventing any backboard effect (snooker shots must be almost perfectly straight in). The facings in Russian billiards are even more challenging, being straight and angled inward rather than outward, which results in the of the pocket, barely wide enough to accept a ball, rejecting any but the most accurate shots.

1.  Verb, passive, intransitive: For a ball to be pocketed. "The 8 ball fell early, so the game was over quickly."

2.  Noun: The curved edge cut into the table at which the hole of the actually begins inside the pocket . The fall may be a sheer drop, as on tournament-standard snooker tables, or have a beveled, down-sloping rim, as on pool tables. A ball is, of course, much more likely to when there is no bevel. How far into the pocket the fall begins is one factor that determines "" or difficulty.

A where the rules are blatantly, intentionally violated; in contexts where this qualifies as unsportsmanlike conduct, a stiffer penalty may apply (e.g. loss of ) than normal for a foul.

In snooker, a situation during a in which the first line of the remaining grouped together, where the original was, are in a straight horizontal line. This has implications when opening the pack, as a contact off the top cushion will usually cause the cue-ball to stick to the red and fail to develop a potting opportunity.

A shot that has an ostensibly positive outcome for the player, although it was not what the player intended. Examples of flukes include an unexpected off several or other balls having missed the pocket aimed for, or a lucky position after having missed a shot. Many players are apologetic after a fluke. In many games, flukes result in a loss of turn, although some rule sets (most notably those of snooker, nine-ball and related games, and the eight-ball rules of the American Poolplayers Association and its affiliates) count flukes as valid, point-making shots.

A shot in which the is struck above its equator with sufficient to cause the cue ball to travel forward after it contacts an . When a cue ball with follow on it contacts an object ball squarely (a center-to-center hit), the cue ball travels directly forward through the space previously occupied by the object ball (and can sometimes even be used to pocket a second ball). By contrast, on a cut shot, a cue ball with follow on it will first travel on the after striking the object ball, and then arc forward, widening the angle. ''See illustration at .''

On a shot, the extension of the cue stick through the position during the end of a player's stroke in the direction originally aimed.

''Same as ().''

A violation of a particular game's rules for which a set penalty is imposed. In many pool games the penalty for a foul is ball-in-hand anywhere on the table for the opponent. In some games such as straight pool, a foul results in a loss of one or more points. In one-pocket, in which a set number of balls must be made in a specific pocket, upon a foul the player must return a ball to the table. In some games, three successive fouls in a row brings the loss of a game. In straight pool, a third successive foul results in a loss of 16 points (15 plus one for the foul).

In UK eight-ball this would normally give the opponent the option of one of two plays: (1) with ; (2) being allowed to contact, or even , a ball other than one from their set from the snookered position (although the black may not be potted), with the loss of the first shot. In addition, some variations of the game allow the player to pot one of the opposition's balls, on the first visit only, without the loss of a "free shot".

In snooker, it allows a player to call any ball as the ball they would have wanted to play, potting it for the same number of points, or the opponent can be put back in without the same privilege, having to play the ball snookered on. The definition of ''snooker'' on this occasion means the opponent cannot strike both extreme edges of the (or a cluster of touching balls).

2.  Playing loose and carefree.

3.  ''Same as .''

To dedicate a set amount of money that a gambling match will be played to; no one may quit until one player or the other has won the "frozen up" funds.

''Chiefly American:'' A resting ball that is in actual contact with a or with one or more other balls is said to be "frozen" (or, colloquially, "froze") to that cushion or the touching ball(s). ''(For frozen combination/combo, frozen kiss, etc., that is almost impossible to miss, see the more common variants under ).'' The chiefly British "" is equivalent to "frozen", but only applied to frozen/tight to a cushion, not to another ball. For situations in which the is frozen to an , different rule sets have different approaches. In some, the cue ball must be addressed with the cue at an angle at least 45 degrees divergent from an imaginary line running through the center of the balls, to minimize chances of a . In snooker (and some British pool rules), this is called a , and the cue ball must be shot away from the object ball without the latter moving.

''Also outside gearing , etc.'': Precise application of to counter the effects of ( of the from its expected path), by applying counter- in the direction opposite to that which would increase the friction- and rolling-curve deflection of the object ball from the desired path. Gearing spin can also be used as a hedge to minimize the effects of imminently predicted (also known as or, in British and especially snooker terminology, ). "Gearing" outside is not a type or style of outside spin, but an subjectively judged ''amount'' of it – enough to cause the cue ball rotation to affect the object ball's rotation in a desired way through momentarily prolonged contact, like two gears interacting. This is relative to specific playing conditions, including the shot angle and force, whether other compensation mechanisms are being used such slit over-cutting to thwart throw, and the cleanliness condition of the balls. The term ''gearing outside '' is technical jargon rather than player slang; it was introduced by billiards-focused physicist and mechanical engineer David G. Alciatore in the 2000s.

A shot aimed so that the center of the cue ball is in line with the edge of the object ball, eclipsing half of the ball. "Hit it just a little thinner than half-ball." Assuming a does not occur, the shot will impart post-contact momentum on the object ball in a direction 30° (which is $\arcsin(1-x)$, where $x$ is the fraction of object ball eclipsed: in this case) off the direction of the cue-ball's pre-contact momentum. Also notable because the carom angle the cue ball takes is more consistent than at other s.

In snooker and English billiards, a that is approximately 3 metres long and used with a of about the same length, used for shots that cannot be reached with normal rests and cues.

In snooker and other British usages, a of between 50 and 99 points (100 points or more being called a century), which requires at least 12 consecutive balls (e.g. the last three reds with at least two blacks and a pink, followed by all the colours).

The term principally survives in English billiards, in which both types of shots are -scoring. Formerly, a large number of different games made use of the two types of hazards as point scorers or losers in various ways (thus their suggestive names). The term ultimately derives from holes or pockets in the table to be avoided, in very early forms of billiards.

Some billiard halls and even entire leagues prohibit all jump (and usually also ) shots, out of fears of damage to the equipment, especially the cloth. Specialized exist to better facilitate jump shots; they are usually shorter and lighter, and with harder tips, than normal cues. Jump shots that go through or into objects rather than over them are common in trick shot ( artistic pool and artistic billiards) competition.

''Also jump stick.''

1.  ''Short for .'' Also used as a verb, "to kick t (US).

2.  ''Same as (US) and .'' Chiefly British: Exaggerated of ball trajectories on impact, generally due to stuck on one of the balls. Kick is the bane of snooker players, even at top professional levels, and is why they so frequently ask a referee to clean a ball. Because of the comparatively light weight of snooker balls, and much smaller margins of error due to sizes on a very large table, the effect of a kick can cause a seemingly easy snooker shot to miss widely. Even if the kick was mostly vertical, due to () or () rather than , and the shot was ted, a kick often results in balls visibly jumping upon impact, resulting in a great loss of cue ball momentum, which can wreck the shot's and leave the player with poor options. On even medium-distance shots, however, an outright miss is more likely. Noun, verb, and rare adjective usage as per "cling". ''(See for less snooker-specific notes.)''

If the player's ''intention'' was to cause two object balls to kiss (e.g. to pocket a shot ball by ricocheting it off a stationary one), it is often called a . ''Compare ; contrast .''

The area on the table behind the . The origin of the term has been the subject of some speculation but the best explanation known is that in the 1800s, many homes did not have room for both a billiard table and a dining room table. The solution was a billiards table that had a cover converting it into a dining table. Kept in the dining room, play on such a table was often restricted by the size of the room, so it would be placed so that the head rail would face the connected kitchen door, thus affording a player room for the backswing without hitting a wall. A player was therefore either half or sometimes fully (literally) "in the kitchen" when breaking the balls. ''See also .''

One of two jutting points or curves of the of the on either side of each where cushion and pocket meet, forming the of the pocket. The knuckles are the intersection of the outer edge of the cushions, parallel to the , and the pocket . The knuckles are protrusive and comparatively sharp on a pool table, the facings of which can be used like a basketball backboard to rebound a ball into a pocket. On billiard tables for snooker, English billiards and various other games, the knuckles are rounded, and thwart the backboard effect. The curvature of snooker and English billiards knuckles are determined by produced by the World Professional Billiards and Snooker Association. Russian pyramid tables also have pointed knuckles, but the facings are angled inward, so the knuckles cannot be used as a backboard. The knuckle is also known as a , or , depending on area and the company one keeps. ''See illustration at the entry.''

''Also the lag (noun), lagging, lag for the break, and lagging for the break.''
To determine the order of play, players (representing only themselves, or sometimes teams) each near simultaneously shoot a ball from the (or in British games, from the ) to the and back toward the . Whichever shooter's ball comes to rest closest to the bottom rail gets to choose who . It is permissible but not required for the lagged ball to touch or rebound off the bottom rail, but not to touch the side rails. Lagging is usually a two-party activity, though there are games such as cutthroat in which three players might lag. In the case of a tie, the tying shooters re-lag. The lag is most often used in tournament play or other competitions.
In hard-break games like nine-ball and eight-ball the winner of the lag would normally take the break, while in soft-break games like straight pool would likely require the loser of the lag to break, since breaking would be a disadvantage. ''See also .''

''Also last pocket.''
A common rule in informal , especially bar/pub eight-ball, in which the must be () in the same pocket as the shooter's last (each player may be said to eventually "own" a pocket, for the duration of the game, in which their 8 ball shot must be played if they have already run out their ). The variant is not extremely common in the United States or the UK, but is near-universal in much of Latin America (where two are permitted when attempting the 8 ball shot and count as simple fouls, with only a third scratch constituting a loss of game). Last pocket is also common in North Africa. Last-pocket rules require careful , and frequently result in and with the 8 ball.

An organization that promotes competitive, usually team, amateur cue sports, most commonly pool, especially eight-ball and nine-ball, although there are also well-established snooker leagues. Some leagues, many of which are decades old, are entirely local and either informal or incorporated, and may use their own local rules or may have adopted more widely published rulesets, such as those of the WPA. Other leagues are organized on a multi-regional or even international level, and may be non-profit or for-profit enterprises, usually with their own fine-tuned rule books. Despite differences, the largest leagues are increasingly converging toward the WPA rules, with the exception of the APA/CPA, which retains rules much closer to US-style . At least four major pool leagues hold international championships in Las Vegas, Nevada annually (APA/CPA, BCAPL, VNEA and ACS/CCS). Some leagues also offer tournaments, events, artistic pool competition, and other non-team activities. ''(See :Cue sports leagues for a listing of articles on various leagues.)''

As in many other sports, "legal" means not causing or likely to cause a (the opposite being ). A legal ''hit'' is one in which the requirements for a non-foul hit are met (e.g., in nine-ball, the lowest-numbered ball on the table was hit by the first, and at least one was , or any ball reached a , after the hit on the first object ball.). A legal ''shot'' is one in which no foul of any kind was involved (e.g. there was not a by the cue, the player's hand did not move a ball, etc.). A legal ''stroke'' is one in which the cue obeyed the rules (e.g. the shooter did not perform an illegal by scooping under the cue ball with the cue ). A legal ''ball'' is a , an object ball at which it is permissible for the player to shoot. And so on. The term can be used in many ways consistent with these examples ("legal pocket" in one-pocket, "legal equipment" under tournament specifications, etc.).

A player is said to be a "lemon", "lemon man", or "playing on the lemon" when they intentionally play below their true ability in order to attract more gambling action and win more money. Players who fall for the ruse would be less likely to gamble with the lemon if they showed their full ability at all times.

A bank shot from one end of the table to the other (i.e. across the ). Long banks are considerably more difficult, because of the smaller margin for error due to distance and angle widening, than banks and short cross-corner banks from the same end of the table.

The forerunner of the cue was the mace, an implement similar to a light-weight golf club, with a foot that was generally used to shove rather than strike the cue ball. When the ball was against a , use of the mace was difficult (the foot would not fit under the edge of the cushion to strike the ball squarely), and by 1670 experienced players often used the tail or butt end of the mace instead.

1.  In , a that involves lining up a number of balls, for example along the , then, after striking the toward a , hitting the other balls directly with the into that pocket before the cue ball reaches it.

2.  In , a where a number of object balls are placed in a row to form a line, sometimes near a , or in a line and the cue ball is shot into the balls so as to reverberate between them while traveling and hit each one of the object balls in series, issuing a machine gun-like sound.

A that, due to embedded iron content, is responsive enough to a strong magnet that a modern coin-operated with a magnetic can distinguish and separate the cue ball from the . Magnetic cue balls are usually the same standard size as the object balls in the set, and near regulation weight, typically 0.5 to 1 ounce (14–28 g) heavier than the object balls. As such they do not suffer the playability problems of either excessively dense, ceramic "" or notable oversized "" cue balls, and demonstrate only minimal . Magnetic balls are standard equipment in some leagues, including the VNEA. Magnetics come in three construction types of iron embedded in the same phenolic resin or other modern, resilient plastic that the are made of: a solid metal core (prone to being off-center and not rolling true); small metal bars distributed around the interior of the ball (the most common, and less prone but not immune to balance defects); and tiny metal filings throughout the material (the most consistent, only made by one manufacturer, and expensive).

A special stick with a grooved, slotted or otherwise supportive end attachment that helps guide the cue stick – a stand-in for the hand. It is usually used only when the shot cannot be comfortably reached with a hand bridge. In American English, often shortened to bridge or called a bridge stick; the term is also common.

An entire class of different mechanical bridges exist for snooker, called ''(see that entry for details)'', also commonly used in blackball and English billiards.

Mechanical bridges have many derogatory nicknames, such as "", "crutch", "granny stick", and "sissy stick", because of the perception by many amateur players that they are evidence of weak playing skills or technique (the opposite is actually true).

Small mechanical bridges, that stand on the table surface instead of being mounted on sticks, exist for disabled players who do not have or cannot use both hands or arms.

In snooker, a calls a miss when a player by failing to hit the and the referee decides that the player has not made a good enough attempt to hit the ball. The miss rule gives the opponent the option to have the referee replace the balls to their original positions and make the player take the shot again. A miss usually occurs when a player makes an unsuccessful attempt at escaping from a snooker. It is a controversial rule aimed at formally discouraging . In professional snooker, a referee will almost always call a miss on any foul where the player misses the ball on, regardless of how close the player comes to hitting it. If a player is called for a miss three times in a single visit while not snookered, they forfeit the frame; to avoid this, players almost always play an easy hit on their third attempt, even if it is likely to leave a chance for the opponent.

A directional pile created by the short fuzzy ends of fibers on the surface of projecting upward from the lie and which create a favorable and unfavorable direction for rolling balls. The convention in most billiards games in which directional nap cloth is used is to brush the cloth along the table in the same direction of the nap, usually from the end that a player . In snooker and UK eight-ball especially, this creates the effect of in the direction of the nap, the most-affected shot being a slow roll into a against the nap. It is commonly referred to in the fuller term "nap of the cloth." When nap is used in relation to woven cloths that have no directional pile, such as those typically used in the U.S. for pool tables, the term simply refers to the fuzziness of the cloth.

The playing surface is defined by the measurements lengthwise and widthwise between the cushion noses (though specifications may simply refer to the cushion for short in that context). Artistic pool and other forms of trick shots sometimes call for shots to go beyond the bounds of the playing surface, e.g. a off the table into a boot on the floor, in Mike Massey's classic "boot shot".

The side of a . To "aim for the profession side of the pocket" is to slightly a difficult corner-pocket , to , rather than , especially in nine-ball. Erring too much in this direction is "missing on the professional side of the pocket." It is so called because experienced players understand that on a thin cut, overcutting the object ball to a corner pocket will far more often leave the object ball in an unfavorable position, i.e. along the for the incoming opponent than will an undercut, which often leaves the object ball sitting in front of or nearby the pocket it had been intended for on a miss.

''As an adjective or compound noun: push-out.''
A rule in many games (most notably nine-ball, after and only after the break shot), allowing a player to "push out" the cue ball to a new position without having to contact any ball, much less pocket one or drive it to a , but not counting any pocketed ball as valid (other foul rules apply, such as , the cue ball, etc.), with the caveat that the opponent may shoot from the new cue ball position or give the shot back to the pusher who must shoot from the new position. In nine-ball particularly, and derived games such as seven-ball and ten-ball, pocketing the on a push-out results in that ball being (which can be used to strategic advantage in certain circumstances, such as when the break leaves no shot on the , and failure to hit it would give the incoming player an instant-win on the money ball).

1.  A geometric form, usually aluminum, wooden or plastic, used to assist in setting up balls in games like eight-ball, nine-ball, and snooker. The rack allows for more consistently tight grouping of balls, which is necessary for a successful shot.

This is similar to a , with the key difference being that the person executing the "rack and run" did not break the balls in that game.

An outgrowth of the concept, a racking template is a tool used in place of a traditional rigid ball rack for pool or snooker balls, consisting of a very thin, e.g. , sheet of material such as paper or plastic with holes into which settle snugly against one another to form a tight rack (). The template is placed, stencil-like, in racking position, with the lead ball's hole directly over the center of the . The balls are then placed onto the template and arranged to settle into their holes, forming a tight rack. Unlike with a training template, the balls are not tapped to create divots, and instead the template is left in place until after the break shot at which time it can be removed (unless balls are still sitting on top of it). Manufacturers such as Magic Ball Rack insist that racking templates are designed "to affect the balls to a minimum". Although Magic Ball Rack implies development work since 2006, other evidence suggests invention, by Magic Ball Rack's founder, in mid-2009, with product announcement taking place in September of that year.''See also .''

An upright object resembling a miniature bowling pin, cone or obelisk. Skittles, as employed in billiards games, have been so-called since at least 1634. One standardized size, for the game five-pins, is 25 mm (1 in.) tall, with 7 mm (0.28 in.) round bases, though larger variants have long existed for other games such as Danish pin billiards. Depending upon the game there may be one skittle, or several, and they may be targets to hit (often via a ) or obstacles to avoid, usually the former. They are also sometimes called , though that term can be ambiguous. Because of the increasing international popularity of the game five-pins, which originated in Italy, they are sometimes also known by their Italian name, ''birillo'' (plural ''birilli''), even in English. Skittles are also used as obstacles in some artistic billiards shots. Flat, thin rectangular skittles, like large plastic dominoes, approximately 6 in. tall by 3 in. wide, and placed upright like obelisks on the table in specific spots, are used as targets or s (mostly the latter) in the now-rare and principally Australian games devil's pool (ten white and two black pins) This appears to be a reprint of an older work, of unknown provenance.

Skittles as used in billiards games date to ground billiards (13th century or earlier) played with a , and hand-thrown games of bowls from at least the same era using the same equipment. Ball games using a recognizable form of skittle are known from as early as ca. 3300 BCE in Ancient Egypt.

The effect of shooting regulation-weight with an old-fashioned over-weight , such that the cue ball moves forward to occupy (sometimes only temporarily), or go beyond, the original position of the object ball, even on a draw or stop shot, because the mass of the cue ball exceeds that of the object ball. Players who understand smash-through well can use it intentionally for position play, such as to nudge other object balls nearby the target ball. Smash-through also makes it dangerous in (when equipped with such a cue ball) to pocket straight-on with a instead of by because of the likelihood of the cue ball.

A stage in a of snooker where the points difference between the players exceeds the maximum number of points remaining on the table. The trailing player may either the frame at this stage or attempt to overcome the points deficit by securing penalty points from , typically by placing the leading player in . The number of snookers required is usually calculated as the number of four-point penalties that—in addition to the maximum points remaining on the table—would enable the trailing player to win the frame outright or tie the scores and force a . E.g., a player who trails by 42 points with 35 points remaining is said to ''"require two snookers"'' because two four-point fouls, in addition to the remaining 35 points, would enable that player to win the frame by one point. If the or is the lowest-valued ball remaining on the table, the number of snookers required is calculated in terms of five- or six-point penalties respectively. A can also help a trailing player overcome a points deficit. When a player can at best tie with the points remaining on the table, the will no longer apply the should either player fail to escape from a snooker. The miss rule still applies at the snookers required stage if a player misses a ball while not snookered.

The game is played by each player trying to all three balls (the same player remaining at the table until this is done) in as few shots as possible and without incurring any s. Luck plays a more significant role in this game than usual, due to the possibility of pocketing two or even all three balls on the .

2.  The spelled-out name of the .

The three-foul rule describes a situation in which a player is assessed a defined penalty after committing a third successive foul. The exact penalty, its prerequisites and whether it is in place at all, vary depending on the games. In nine-ball and straight pool, a player must be the told they are on two fouls in order to transgress the rule, and if violated, results in a loss of game for in former, and a special point penalty of a loss of fifteen points (plus one for the foul itself) in the latter together with the ability to require the violator to rerack and rebreak. In WEPF eight-ball, it is a loss of game if a player commits a third foul while shooting at . In snooker, three successive fouls from a non-ed position result in forfeiting the . Repeat fouls from a snookered position are quite common – Dave Harold holds the record in a competitive match, missing the same shot 14 successive times.

The normal phenomenon, present to some degree on all s, whereby the object ball is pushed in a direction slight off the pure "" contact angle between the two balls. Throw is caused by the friction imparted from the first, moving ball sliding or rotating against the second, stationary ball. ''Same as object-ball .'' While throw is most easily observed between the and an object ball, it also happens between two or more object balls, which is one of the factors that makes s challenging.

The amount of this deflection of an object ball from its expected path is increased by several things, including by dirty or pitted balls that briefly grip each other more, by a thick cut-shot angle that provides for extended friction between the balls (cut-induced throw), by slow ball-contact speed (speed-induced throw) for the same reason, by s for the same reason, and by the object ball being impacted by a ball that is rapidly (spin- or -induced throw), which causes the object ball to roll in a curve more toward that throw direction. Throw is reduced by higher-speed impact, by or (bottom or top spin), and by side-spin counter to the direction of the natural throw. Skilled players thus often shoot cut shots with a small amount of – gearing outside English – to neutralize the cut-induced throw that widens the shot away from the , though other techniques may be required instead or in combination with that, depending on the desired cue-ball position at the end of the shot.

This technique involves all three balls being grouped in close proximity at the top end of the table and scoring with a succession of short-range pots and cannons. A typical starting point is with the red placed on its spot, object white on or near the centreline somewhere between the spot and the top cushion, and the cueball posed nearby to pot the red or make a gentle cannon. If the pot, then it should be played so as to leave the cueball in a good position for the next shot. If the cannon, then the purpose is to disturb the object white as little as possible and finish clear to pot the red that has been left near the corner pocket. Then in potting the red the cueball must again be left in a good position for the next shot, and so on. This form of play makes it possible to compile really big breaks in relatively short time.

''Same as .''

A thin sheet of rigid material in the size and shape of a physical ball rack (e.g. a for nine-ball), with holes drilled though it, which is used to make permanent in the cloth of the table, one at a time for each ball in the pattern, by placing the template on the table, and then a ball in one of the holes in the template by tapping it sharply from above to create the cloth indentation. The holes are spaced slightly closer than the regulation ball width of 2¹⁄₂ inch (57.15 mm) apart, so that when the balls settle partially into their divots, the outer sides of these indentations create ball-on-ball pressure, pushing the balls together tightly. The purpose of the template is to do away with using a physical rack, with racking instead being performed simply by placing the balls into position, and the divots aligning them into the tightest possible formation automatically. This prevents accidental loose racks, and also thwarts the possibility of cheating by manipulating the ball positions while racking. The European Pocket Billiard Federation (EPBF, Europe's WPA affiliate organization) has adopted this racking technique for its professional Euro-Tour event series. ''See also , .''

1.  A rack in the form of an equilateral triangle. There are different sizes of triangles for different games (which use different ball sizes and numbers of balls), including the fifteen ball racks for snooker and various pool games such as eight-ball and blackball.
