9 Men’s Morris

Nine Men’s Morris is an abstract strategy board game for two players that emerged from the Roman Empire. The game’s popularity peaked in Medieval England. The board consists of a grid with twenty-four intersections, or points. Each player has nine “men” in either black or 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 they could no longer form mills and thus be unable to win), or by leaving them without a legal move.
