Abstract
Abstract A multi-level game board structure for three-dimensional chess and checker games. The board structure has an odd number of game boards mounted one over the other in vertically spaced relation and each defining playing squares arranged in rank and file rows containing equal numbers of squares. Each game board above and below the center board has two less rank and file rows than the adjacent board in the direction of the center board. The boards are relatively oriented so that playing squares in any vertical line through the board structure alternate in color. The chess and checker game pieces are the same as used in conventional chess and checker games except that the chess pieces include additional pawns and the checker pieces include additional checkers. The chess and checker games are played according to essentially conventional chess and checker game rules except that the game pieces may be moved in both horizontal and vertical directions.
