Each player has 4 good ghosts and 4 evil ghosts - you only know whether your own ghosts are good or evil. Ghosts are lined up on a 6x6 square board. Each turn a player moves one of his ghosts one square orthogonally. Moving into an opponent's ghost kills the ghost. The object of the game is to get rid of your own evil ghosts, kill your opponent's good ghosts, or move one of your good ghosts off the board from one of your opponent's corner squares.
