Reversi Software
Reversi is a Abstract strategy game, strategy board game for two players, played on an 8×8 uncheckered board. It was invented in 1883. ''Othello'', a variant with a fixed initial setup of the board, was patented in 1971. Basics Two players compete, using 64 identical game pieces ("disks") that are light on one side and dark on the other. Each player chooses one color to use throughout the game. Players take turns placing one disk on an empty square, with their assigned color facing up. After a play is made, any disks of the opponent's color that lie in a straight line bounded by the one just played and another one in the current player's color are turned over. When all playable empty squares are filled, the player with more disks showing in their own color wins the game. History Original version Englishmen Lewis Waterman and John W. Mollett both claim to have invented the game of reversi in 1883, each denouncing the other as a fraud. The game gained considerable popula ...

Board Game
A board game is a type of tabletop game that involves small objects () that are placed and moved in particular ways on a specially designed patterned game board, potentially including other components, e.g. dice. The earliest known uses of the term "board game" are between the 1840s and 1850s. While game boards are a necessary and sufficient condition of this genre, card games that do not use a standard deck of cards, as well as games that use neither cards nor a game board, are often colloquially included, with some referring to this genre generally as "table and board games" or simply "tabletop games". Eras Ancient era Board games have been played, traveled, and evolved in most cultures and societies throughout history Board games have been discovered in a number of archaeological sites. The oldest discovered gaming pieces were discovered in southwest Turkey, a set of elaborate sculptured stones in sets of four designed for a chess-like game, which were created during the ...

Moors
The term Moor is an Endonym and exonym, exonym used in European languages to designate the Muslims, Muslim populations of North Africa (the Maghreb) and the Iberian Peninsula (particularly al-Andalus) during the Middle Ages. Moors are not a single, distinct or Ethnonym, self-defined people. Europeans of the Middle Ages and the early modern period variously applied the name to Arabs, Berbers, and Islam in Europe, Muslim Europeans.

The 1911 ''Encyclopædia Britannica'' observed that the term had "no real ethnological value." The word has racial connotations and it has fallen out of fashion among scholars since the mid-20th century. The word is also used ...

Logistello
Logistello is a computer program that plays the game Othello, also known as Reversi. Logistello was written by Michael Buro and is regarded as a strong player, having beaten the human world champion Takeshi Murakami six games to none in 1997 — the best Othello programs are now much stronger than any human player. Logistello's evaluation function is based on disc patterns and features over a million numerical parameters which were tuned using linear regression In statistics, linear regression is a statistical model, model that estimates the relationship between a Scalar (mathematics), scalar response (dependent variable) and one or more explanatory variables (regressor or independent variable).

Blindfold Chess
Blindfold chess, also known as ''sans voir'', is a form of chess play wherein the players do not see the positions of the pieces and do not touch them. This forces players to maintain a mental model of the positions of the pieces. Moves are communicated via a recognized chess notation. Blindfold chess was considered miraculous for centuries but now there is greater recognition of people who can keep track of more than one simultaneous blindfolded game. In Simultaneous exhibition, simultaneous blindfold play, an intermediary usually relays the moves between the players. Early history Blindfold chess was first played quite early on in the history of chess. The earliest name to be associated with play without the use of a material board is that of Sa'id bin Jubair (665–714) in the Middle East. In Europe, playing chess blindfolded became popular as a means of handicapping a chess master when facing a weaker opponent, or of simply displaying one's superior abilities. H. J. R. ...

Computer Othello
Computer Othello refers to computer architecture encompassing computer hardware and computer software capable of playing the game of Othello. It was notably included in Microsoft Windows from 1.0 to XP, where it is simply known as Reversi. Availability There are many Othello programs such as NTest, Saio, Edax, Cassio, Pointy Stone, Herakles, WZebra, and Logistello that can be downloaded from the Internet for free. These programs, when run on any up-to-date computer, can play games in which the best human players are easily defeated. This is because although the consequences of moves are predictable for both computers and humans, computers are better at exploring them. Search techniques Computer Othello programs search for any possible legal moves using a game tree. In theory, they examine all positions / nodes, where each move by one player is called a "ply". This search continues until a certain maximum search depth or the program determines that a final "leaf" position ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bye (sports)
In sport, a bye is the preferential status of a player or team that is automatically advanced to the next round of a tournament without having to play an opponent in an early round. In knockout (elimination) tournaments, byes may be assigned either to reward the highest ranked participant(s), or randomly, to make a working bracket if the number of participants is not a power of two (e.g. 16 or 32). In round-robin tournaments, usually one competitor gets a bye in each round when there are an odd number of competitors, as it is impossible for all competitors to play in the same round. However, over the whole tournament, each plays the same number of games as well as sitting out for the same number of rounds. The "Berger Tables" used by FIDE for chess tournaments, provide pairings for even numbered pools and simply state that "Where there is an odd number of players, the highest number counts as a bye." Similar to the round-robin context, in league sports with weekly regular-seaso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Algebraic Notation (chess)
Algebraic notation is the standard method of chess notation, used for recording and describing moves. It is based on a system of coordinates to identify each square on the board uniquely. It is now almost universally used by books, magazines, newspapers and software, and is the only form of notation recognized by FIDE, the international chess governing body. An early form of algebraic notation was invented by the Syrian player Philip Stamma in the 18th century. In the 19th century, it came into general use in German chess literature and was subsequently adopted in Russian chess literature. Descriptive notation, based on abbreviated natural language, was generally used in English language chess publications until the 1980s. Similar descriptive systems were in use in Spain and France. A few players still use descriptive notation, but it is no longer recognized by FIDE, and may not be used as evidence in the event of a dispute. The term "algebraic notation" may be considered a misn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrabble
''Scrabble'' is a word game in which two to four players score points by placing tiles, each bearing a single letter, onto a Board game, game board divided into a 15×15 grid of squares. The tiles must form words that, in crossword fashion, read left to right in rows or downward in columns and are included in a standard dictionary or lexicon. American architect Alfred Mosher Butts invented the game in 1931. ''Scrabble'' is produced in the United States and Canada by Hasbro, under the brands of both of its subsidiaries, Milton Bradley Company, Milton Bradley and Parker Brothers. Mattel owns the rights to manufacture ''Scrabble'' outside the U.S. and Canada. As of 2008, the game is sold in 121 countries and is available in more than 30 languages; approximately 150 million sets have been sold worldwide, and roughly one-third of American homes and half of British homes have a ''Scrabble'' set. There are approximately 4,000 ''Scrabble'' clubs around the world. Equipment ''Scrabble ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
