The objective is to capture as many of your opponent's pieces as possible. This is done by sandwiching one or more of his pieces between two of yours. In addition to regular pieces, each player receives four face pieces. There are five home dots at the center of the board. Each face piece placed next to a home dot scores two points at the end of a game. All other pieces score one point. The game ends when all the pieces are played or when neither player can make a move. Tradition requires the winning player to suck in his breath and say "ah- s-o-o-o-o" at the end of the game.
