A multi-tier game board upon which games such as chess and checkers may be played with the usual playing pieces and under the usual rules. The game board includes a first tier of square ring configuration having 28 playing squares, a second tier of square ring configuration having 20 playing squares, a third tier of square ring configuration having 12 playing squares and a fourth tier of square planar configuration having 4 playing squares. The four tiers may be nestingly positioned with respect to each other to provide a conventional 64 square playing board or may be vertically displaced and vertically aligned with respect to each other to provide a three dimensional game board.
