Balls

In most carom billiards games, the set of three standard balls includes a white cue ball, a second cue ball in yellow, and a third object ball in red.
Historically, the second cue ball was white with red or black spots to differentiate it; both types of ball sets are permitted in tournament play.
The balls are significantly larger and heavier than their pool or snooker counterparts, with a diameter of , and a weight ranging between with a typical weight of .

. The dominant material from 1627 until the early- to mid-20th century was ivory. The quest for an alternative to ivory was primarily driven by economic considerations and concerns for the safety of elephant hunters, rather than environmental or animal-welfare issues. The impetus for this search was, in part, the announcement by New York billiard table manufacturer
Brunswick-Balke-Collender offering a $10,000 prize for the development of a substitute material. The initial successful alternative came in the form of celluloid, invented by
John Wesley Hyatt

in 1868. However, while celluloid was a viable substitute, it proved to be volatile and highly flammable, with instances of explosions occurring during its manufacturing process.
Cues
Carom billiard cues have specialized refinements making them different from cues used in other cue sports. Carom cues tend to be shorter and lighter overall, with a shorter , a thicker and , a wooden joint (in high-end examples), and wood-to-wood joint. They have a sharply conical , and a smaller diameter as compared with pool cues. Typical carom cues are in length and in weight – lighter for straight rail, heavier for three-cushion – with a tip in diameter.
These dimensions make the cue significantly stiffer, which aids in handling the larger and heavier balls used in carom billiards. It also acts to reduce (sometimes called "squirt"), which is displacement of the cue ball's path away from the parallel line formed by the cue stick's direction of travel. It is a factor that occurs every time is employed, and its effects are magnified by speed. In some carom games, deflection plays a large role because many shots require extremes of side-spin, coupled with great speed; this is a combination typically minimized as much as possible, by contrast, in pool.
History of games
Straight rail
Straight rail is thought to date to the 18th century, although no exact time of origin is known. The object of straight rail is simple: one point, called a "count", is scored each time a player's cue ball makes contact with both object balls (the second cue ball and the third ball) on a single . A win is achieved by reaching an agreed upon number of counts.
At straight rail's inception there was no restriction on the manner of scoring. However, the technique of ''crotching'', or freezing two balls into the corner where the rails meet—the ''crotch''—vastly increasing counts, resulted in an 1862 rule which allowed only three counts before at least one ball had to be driven away. Techniques continued to develop which increased counts greatly despite the crotching prohibition, especially the development of a variety of "" techniques. The most important of these, the ', involves the progressive nudging of the object balls down a rail, ideally moving them only a small amount on each count, keeping them close together and positioned at the end of each stroke in the same or near the same configuration such that the nurse can be replicated again and again.
Straight rail is still popular in Europe, where it is considered a fine practice game for both balkline and three-cushion billiards. Additionally, Europe hosts professional competitions known as ''pentathlons'' in which straight rail is featured as one of five billiards disciplines at which players compete, the other four being 47.1 balkline,
cushion caroms, 71.2 balkline, and three-cushion billiards.
Straight rail was played professionally in the United States from 1873 to 1879, but is uncommon there today.
Balkline

In 1879, a variant called the "champion's game" or "limited-rail" was introduced with the specific intent of frustrating the rail nurse.
The game employed diagonal lines at the table's corners to regions where counts were restricted. Ultimately, however, despite its divergence from straight rail, the champion's game simply expanded the dimensions of the balk space defined under the existing crotch prohibition which was not sufficient to stop nursing.
Balkline succeeded the champion's game, adding more rules to curb nursing techniques. In the balkline games, the entire table is divided into rectangular balk spaces, by drawing pairs of balklines lengthwise and widthwise across the table parallel from each rail. This divides the table into nine rectangular balkspaces. Such balk spaces define areas of the in which a player may only score up to a threshold number of points while the are within that region.
Additionally, rectangles are drawn where each balkline meets a rail, called ''anchor spaces'', which developed to stop a number of nursing techniques that exploited the fact that if the object balls straddled a balkline, no count limit was in place.
For the most part, the differences between one balkline game to another is defined by two measures: the spacing of the balklines and the number of points that are allowed in each balk space before at least one ball must leave the region. Generally, balkline games and their particular restrictions are given numerical names indicating both of these characteristics; the first number indicated either inches or centimeters depending on the game, and the second, after a dot or a slash, indicates the count restriction in balk spaces, which is always either one or two. For example, in ''18.2 balkline'', one of the more prominent balkline games and of US origin, the name indicates that balklines are drawn distant from each rail, and only two counts are allowed in a balk space before a ball must leave.
By contrast, in ''71.2 balkline'', of French invention, lines are drawn distant from each rail, also with a two-count restriction for balk spaces.
In its various incarnations, balkline was the predominant carom discipline from 1883 to the 1930s, when it was overtaken by three-cushion billiards and pool. Balkline is still popular in Europe and the

.
One-cushion
One-cushion carom, or simply cushion carom, also arose in the late 1860s as another alternative to the repetitive play of straight rail, inspired by an early variant of English billiards. The object of the game is to score cushion caroms, meaning a carom off of both object balls with at least one rail cushion being struck before the hit on the second object ball. One-cushion carom is still popular in Europe.
Three-cushion
In three-cushion carom, the object is to carom off both object balls with at least three being contacted before the contact of the cue ball with the second object ball.
Three-cushion is a very difficult game. Averaging one point per is professional-level play, and averaging 1.5 to 2 is world-class play.

, is credited with popularizing the game in the 1870s.
At least one publication categorically states he invented the game as well. The first three-cushion billiards tournament took place 14–31 January 1878, in St. Louis, with McCreery a participant and Leon Magnus the winner. The high run for the tournament was just 6 points, and the high average a 0.75. The game was infrequently played, with many top carom players of the era voicing their dislike of it, until the 1907 introduction of the Lambert Trophy.
By 1924, three-cushion had become so popular that two giants in other billiard disciplines agreed to take up the game especially for a challenge match. On 22 September 1924,

Three-cushion billiards retains great popularity in parts of Europe, Asia, and Latin America,
and is the most popular carom billiards game played in the US today. UMB, as the governing body of the sport, had been staging world three-cushion championships since the late 1920s.
Artistic billiards

In artistic billiards players compete at performing 76 preset shots of varying difficulty. Each set shot has a maximum point value assigned for perfect execution, ranging from a 4-point minimum for lowest level difficulty shots, and climbing to an 11-point maximum for shots deemed highest in difficulty level. There is a total of 500 points available to a player.
Each shot in an artistic billiards match is played from a well-defined position (in some venues within an exacting two millimeter tolerance), and each shot must unfold in an established manner. Players are allowed three attempts at each shot. In general, the shots making up the game, even 4-point shots, require a high degree of skill, devoted practice and specialized knowledge to perform.
