Ludo is a strategy board game for two to four players, in which the players race their four tokens from start to finish according to the rolls of a single die. Like other cross and circle games, Ludo originated from the Indian game Pachisi. The game and its variations are popular in many countries and under various names.
Reversi is a 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.
Checkers, also known as draughts, is a group of strategy board games for two players which involve forward movements of uniform game pieces and mandatory captures by jumping over opponent pieces. Checkers is developed from alquerque. The term "checkers" derives from the checkered board which the game is played on, whereas "draughts" derives from the verb "to draw" or "to move".
Pachisi is a cross and circle board game that originated in Ancient India. It is described in the ancient text Mahabharata under the name of "Pasha". It is played on a board shaped like a symmetrical cross. A player's pieces move around the board based upon a throw of six or seven cowrie shells, with the number of shells resting with the aperture upward indicating the number of spaces to move.
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 unorthodox chess problems, known as fairy chess. 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.
Vernon Rylands Parton was an English chess enthusiast and prolific chess variant inventor, his most renowned variants being Alice chess and Racing Kings. Many of Parton's variants were inspired by the fictional characters and stories in the works of Lewis Carroll. Parton's formal education background, like Lewis Carroll's, was in mathematics. Parton's interests were wide and he was a great believer in Esperanto.
Jungle or dou shou qi is a modern Chinese board game with an obscure history. A British version known as "Jungle King" was sold in the 1960s by the John Waddington company. The game is played on a 7×9 board and is popular with children in the Far East.
Kriegspiel is a chess variant invented by Henry Michael Temple in 1899 and based upon the original Kriegsspiel developed by Georg von Reiswitz in 1812. In this game, each player can see their own pieces but not those of their opponent. For this reason, it is necessary to have a third person act as an umpire, with full information about the progress of the game. Players attempt to move on their turns, and the umpire declares their attempts 'legal' or 'illegal'. If the move is illegal, the player tries again; if it is legal, that move stands. Each player is given information about checks and captures. They may also ask the umpire if there are any legal captures with a pawn. Since the position of the opponent's pieces is unknown, Kriegspiel is a game of imperfect information.
Ludus latrunculorum, latrunculi, or simply latrones was a two-player strategy board game played throughout the Roman Empire. It is said to resemble chess or draughts, as it is generally accepted to be a game of military tactics. Because of the scarcity of sources, reconstruction of the game's rules and basic structure is difficult, and therefore there are multiple interpretations of the available evidence.
Whale Shogi is a modern variant of shogi. It is not, however, Japanese: it was invented by R. Wayne Schmittberger of the United States in 1981. The game is similar to Judkins shogi, but with more pieces, and the pieces are named after types of whale.
Duell, also published under other names, is a two-player board game played with dice on a board of 9×8 squares. Players take turns moving one of their dice in order to capture their opponent's pieces, with the ultimate aim of capturing the opponent's key piece to win the game. It is considered a chess variant.
Running-fight games are board games that essentially combine the method of race games and the goal of elimination-based games such as chess or draughts. Like race games, pieces are moved along linear tracks based on the fall of dice or other lots; but like chess, the object is to capture opponent pieces.
Zillions of Games is a commercial general game playing system developed by Jeff Mallett and Mark Lefler in 1998. The game rules are specified with S-expressions, Zillions rule language. It was designed to handle mostly abstract strategy board games or puzzles. After parsing the rules of the game, the system's artificial intelligence can automatically play one or more players. It treats puzzles as solitaire games and its AI can be used to solve them.
The following outline is provided as an overview of and topical guide to chess:
2000 A.D. is a chess variant created by V. R. Parton which employs fairy chess pieces on a 10×10 board. Parton published the variant in his 1972 monograph My Game for 2000 A.D. and After.
Philip M. Cohen is the inventor of several chess variants. He authored the column "Olla Podrida" in the periodical Nost-algia published by the correspondence game club NOST. The column regularly featured chess variants, many experimental, since 1972.
Three-man chess is a chess variant for three players invented by George R. Dekle Sr. in 1984. The game is played on a hexagonal board comprising 96 quadrilateral cells. Each player controls a standard army of chess pieces.
Stratomic is a chess variant invented by Robert Montay-Marsais in 1972. The game is played on a 10×10 board with all the standard chess pieces present, and in addition, two nuclea pieces and two extra pawns per side. The game brings the concept of modern warfare weaponry to chess.
Dynamo chess is a chess variant invented by chess problemists Hans Klüver and Peter Kahl in 1968. The invention was inspired by the closely related variant push chess, invented by Fred Galvin in 1967. The pieces, board, and starting position of Dynamo chess are the same as in orthodox chess, but captures are eliminated and enemy pieces are instead "pushed" or "pulled" off the board. On any given move, a player can make a standard move as in orthodox chess, or execute a "push move" or a "pull move". A move that is either a push move or a pull move is called a "dynamo move".
