Abstract

The invented four-player chess game includes a plurality of distinguishable sets of playing pieces including pieces equivalent to pawns, rooks, knights, bishops, queens and kings. It also includes a board having a main playing area made from a square matrix of eight-by-eight alternately colored playing spaces with two additional rows of eight alternately colored playing spaces adjacent each side of the main playing area. The game is played by placing each player's set of playing pieces on the game board so that each different set occupies two rows adjacent one side of the main playing area in a conventional chess arrangements. Each player moves, in turn, one of his playing pieces anywhere on the game board according to standard chess rules, except the pieces equivalent to pawns may move up to three spaces forward on each of those pieces' initial move. Playing pieces are captured according to standard chess rules, except the pieces equivalent to pawns initially located at the ends of the first additional rows of alternately colored playing spaces adjacent the main playing area may not move diagonally to capture another piece equivalent to a pawn that has not moved. When more than two players are playing and remain in the game, players are eliminated when their king is captured and actually removed from the board, at which time all the remaining playing pieces in the set of the removed king are taken off the board. Play continues until only two players remain, at which time the game ends when one player checkmates the other player's king or when neither player can checkmate the other player's king.
