Mill Game, known also as Nine Men's Morris (in Italy as Filetto), is a strategy board game for two players.

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 tray 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 men (whereupon tey can no longer form mills and thus are unable to win) or by leaving them without a legal move.
