Computer Olympiad
The Computer Olympiad is a multi-games event in which computer programs compete against each other. For many games, the Computer Olympiads are an opportunity to claim the "world's best computer player" title. First contested in 1989, the majority of the games are board games but other games such as bridge take place as well. In 2010, several puzzles were included in the competition.

History 

Developed in the 1980s by David Levy, the first Computer Olympiad took place in 1989 at the Park Lane Hotel in London. The games ran on a yearly basis until after the 1992 games, when the Olympiad's ruling committee was unable to find a new organiser. This resulted in the games being suspended until 2000 when the Mind Sports Olympiad resurrected them. Recently, the International Computer Games Association (ICGA) has adopted the Computer Olympiad and tries to organise the event on an annual basis.

Summary by game

Abalone

Abalone is a strategy game using a hexagonal patterned board with 14 marbles for each of two players. The objective is to push six of the opponent's marbles off the edge of the board.

Amazons

Amazons is played on a 10×10 chessboard by two players each with four amazons (queen chess pieces). Moves are made to block squares and the winner is the last player able to move his pieces to an unblocked square.

Awari

Awari is an abstract strategy game among the Mancala family of board games (pit and pebble games).

Backgammon 

Backgammon is a board game for two players where the checker-like playing pieces are moved according to the roll of dice; a player wins by removing all of his pieces from the board before his opponent.

Bridge

Bridge is a trick-taking card game for four players.

Bridge participation in the Computer Olympiad was largely discontinued when in 1996 the American Contract Bridge League established a new official World Computer Bridge Championship, to be run annually at a major bridge tournament.  Starting in 1999, that event is now co-sponsored by the World Bridge Federation.

Chess

Chess is a two-player board game played on a checkered game-board with 64 squares arranged in an eight-by-eight grid. Each player begins with 16 pieces of varying characteristics, the objective being to capture one's opponent's king piece.

Many computer-versus-computer events are held beyond those of the Computer Olympiad.

Chinese chess

Chinese chess is a strategy board game for two players from the same family as western or international chess. Known primarily as Xiangqi internationally, the game is referred to as Chinese chess in the Computer Olympiad competitions.

Chinese dark chess
Chinese dark chess is known as Banqi in Chinese.
