"Each player has nine pieces, or ""men"", which move among the board's twenty-four spots. The object of the game is to leave the opposing player with fewer than three pieces or no legal moves.
The game begins with an empty board. Players take turns placing their pieces on empty spots. If a player is able to form a straight row of three pieces along one of the board's lines (i.e. not diagonally), he has a ""mill"" and may remove one of his opponent's pieces from the board; removed pieces may not be placed again. Players must remove any other pieces first before removing a piece from a formed mill. Once all eighteen pieces have been used, players take turns moving."
