The board consists of a grid with twenty-four intersections or points. Each player has nine pieces, or "men", usually coloured black and white. Players try to form 'mills'—three of their own men lined horizontally or vertically—allowing a player to remove an opponent's man from the game. A player wins by reducing the opponent to two pieces (where he could no longer form mills and thus be unable to win), or by leaving him without a legal move. The game proceeds in three phases: 1- Placing men on vacant points 2- Moving men to adjacent points (optional phase) 3- Moving men to any vacant point when the player has been reduced to three men The game is highly addictive!
