A strategy chess-like game. Your objective is to clear the board (graveyard) of your opponent’s pieces (ghouls). Unlike regular chess, you do not see a playing piece until it rises from the grave and you do not know if it will be on your side or your opponent’s until it actually appears.
Each 'chess' piece is ranked in strength from 1 to 6. In general, a higher ranked ghoul can kill another ghoul of equal or lesser strength. However, this does not apply to the pawn - in addition to being able to kill other pawns, it can kill the king, but the king cannot kill the pawn.
The name and strength of a playing piece is shown in the bottom of the game screen.
