A Mill Game which supports many rule variants.
Nine men's morris is a strategy board game for two players
dating at least to the Roman Empire. The game is also
known as nine-man morris, mill, mills, the mill game,
merels, merrills, merelles, marelles, morelles, and
ninepenny marl in English.
Rules:
- A player who aligns three of his pieces on a board line
has a mill and may remove his opponent's piece(s).
- Any player reduces to two pieces and has no option to
form new mills and thus loses the game.
- A player can also lose with more than three pieces
if his opponent blocks them not to be moved.
