Nine men's morris is a strategy board game for two players dating at least to the Roman Empire.[1] The game is also known as nine-man morris, mill, mills, the mill game, merels, merrills, merelles, marelles, morelles, and ninepenny marl[2] in English. In North America, the game has also been called cowboy checkers, and its board is sometimes printed on the back of checkerboards. Nine men's morris is a solved game, that is, a game whose optimal strategy has been calculated. It has been shown that with perfect play from both players, the game results in a draw.[3]

The Latin word merellus means 'gamepiece', which may have been corrupted in English to 'morris',[1] while miles is Latin for soldier.

Three main alternative variations of the game are three, six, and twelve men's morris.
