The object of the game is to have more pieces on the board than the opponent does when the game is over. To make a move place a piece on an empty square so that one (or more) of the opponent's pieces would be flanked and flipped. If a player cannot make a legal move (flip opponent's pieces), the player has to pass. The game is over when either the board is full, or neither player can make a move.
