Abstract
Abstract Three-dimensional chess played on a cubic playing field where moves are executed in cubic planes, and up to one-thousand playing positions are available. Ten boards are mounted over each other, each board defining a ten by ten matrix of one-hundred squares. The game is played by two opponents, each having a king, queen, two knights, two bishops, two rooks, two dukes, and ten pawns, the introduction of a duke being required for true three-dimensional movement of the playing pieces. Playing pieces move in reference to advancement squares, each piece having a defined planar movement pattern. Play on an eight by eight by eight or on an eight by eight by ten playing filed configuration is possible by permitting the duke to occupy the same square as the bishop.
