Xiangqi, commonly known as Chinese chess or elephant chess, is a strategy board game for two players. It is the most popular board game in China. Xiangqi is in the same family of games as shogi, janggi, Western chess, chaturanga, and Indian chess. Besides China and areas with significant ethnic Chinese communities, this game is also a popular pastime in Vietnam, where it is known as cờ tướng, literally 'General's chess'.
Baroque chess is a chess variant invented in 1962 by Robert Abbott. In 1963, at the suggestion of his publisher, he changed the name to Ultima, by which name it is also known. Abbott later considered his invention flawed and suggested amendments to the rules, but these suggestions have been substantially ignored by the gaming community, which continues to play by the 1962 rules. Since the rules for Baroque were first laid down in 1962, some regional variation has arisen, causing the game to diverge from Ultima.
Archon: The Light and the Dark is a 1983 video game developed by Free Fall Associates and one of the first five games published by Electronic Arts. It is superficially similar to chess, in that it takes place on a board with alternating black and white squares, but instead of fixed rules when landing on another player's piece, an arcade-style fight takes place to determine the victor, and each piece has different combat abilities. The health of the player's piece is enhanced when landing on a square of one's own color.
A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventional chess but incorporated into certain chess variants and some chess problems. Compared to conventional pieces, fairy pieces vary mostly in the way they move, but they may also follow special rules for capturing, promotions, etc. Because of the distributed and uncoordinated nature of unorthodox chess development, the same piece can have different names, and different pieces can have the same name in various contexts as it can be noted in the list of fairy chess pieces.
A bitboard is a specialized bit array data structure commonly used in computer systems that play board games, where each bit corresponds to a game board space or piece. This allows parallel bitwise operations to set or query the game state, or determine moves or plays in the game.
Ataxx (アタックス) is a strategy video game published in arcades by Leland Corporation in 1990. Two players compete on a seven-by-seven square grid. The object of the game is for a player to have a majority of the pieces on the board at the end of the game, by converting as many of their opponent's pieces as possible. In a single-player game, the opponents are "bio-invaders from a different dimension."
Martian Chess is an abstract strategy game for two or four players invented by Andrew Looney in 1999. It is played with Icehouse pyramids on a chessboard. To play with a number of players other than two or four, a non-Euclidean surface can be tiled to produce a board of the required size, allowing up to six players.
Janggi, sometimes called Korean chess, is a strategy board game popular on the Korean Peninsula. The game was derived from xiangqi, and is very similar to it, including the starting position of some of the pieces, and the 9×10 gameboard, but without the xiangqi "river" dividing the board horizontally in the middle.
Archon II: Adept is a strategy/action video game developed by Free Fall Associates: Jon Freeman, Paul Reiche III, and Anne Westfall. It was published in 1984 by Electronic Arts for the Atari 8-bit computers and Commodore 64. Ports followed for the Apple II, Amstrad CPC,ZX Spectrum, and Amiga.
Tower of Babel is a computer game for the Amiga, Atari ST and Acorn Archimedes systems programmed by Pete Cooke, developed by Rainbird Software and released by Microprose Software in 1989. It is a puzzle video game played on a three-dimensional tower-like grid viewed in vector graphics with filled polygons.
Dragonchess is a three-dimensional fantasy chess variant created by Gary Gygax, co-creator of the famed role-playing game Dungeons & Dragons. The game was introduced in 1985 in issue No. 100 of Dragon Magazine.
Yari shogi is a modern variant of shogi ; however, it is not Japanese. It was invented in 1981 by Christian Freeling of the Netherlands. This game accentuates shogi’s intrinsically forward range of direction by giving most of the pieces the ability to move any number of free squares orthogonally forward like a shogi lance. The opposite is true of promoted pieces which can move backward with the same power.
Hasami shogi is a variant of shogi. The game has two main variants, and all Hasami variants, unlike other shogi variants, use only one type of piece, and the winning objective is not checkmate. One main variant involves capturing all but one of the opponent's men; the other involves building an unbroken vertical or horizontal chain of five-in-a-row.
Tenjiku shogi is a large-board variant of shogi. The game dates back to the 15th or 16th century and was based on the earlier chu shogi, which itself was based on dai shogi.
Board representation in computer chess is a data structure in a chess program representing the position on the chessboard and associated game state. Board representation is fundamental to all aspects of a chess program including move generation, the evaluation function, and making and unmaking moves as well as maintaining the state of the game during play. Several different board representations exist. Chess programs often utilize more than one board representation at different times, for efficiency. Execution efficiency and memory footprint are the primary factors in choosing a board representation; secondary considerations are effort required to code, test and debug the application.
Khet is a chess-like abstract strategy board game that uses lasers, and was formerly known as Deflexion. Players take turns moving Egyptian-themed pieces around the playing field, firing their low-powered laser diode after each move. Most of the pieces are mirrored on one or more sides, allowing the players to alter the path of the laser through the playing field. When a piece is struck by a laser on a non-mirrored side, it is eliminated from the game.
Ploy is an abstract strategy board game for two or four players, played on a 9x9 board with a set of 15 pieces (2-handed) or 9 pieces per player. Pieces have various horizontal, vertical or diagonal moves somewhat like chess pieces, except directions of movement are limited; pieces change directions of movement by "rotating". Object of the game is to capture the opponent's Commander, or all of his other pieces.
