Abstract: Apparatus for playing a game including a rectangular game board having 40 hexagonally recessed playing spaces in contiguous and aligned relationship representing 5 files and 8 ranks. Two sets of playing pieces, each set having 9 hexagonal playing pieces adapted to fit in the recessed playing spaces are provided. Each playing piece of each set is marked so as to indicate particular sides of the piece which are invulnerable to attack from an aligned playing piece of the opposing set. In playing a game, a piece may move in any aligned direction any number of spaces but may not "jump" another playing piece. A playing piece may also be rotated in position, constituting a move. A piece having a vulnerable side exposed to an aligned opposing piece is captured and removed from the game and the capturing piece takes its position. The game is won by placing a specified piece in a checkmate position.
