Nine Men's Morris is one of the earliest board game in recorded history. It is a two players board game that dated back to 1400 BC emerged from the Roman Empire. The game is also known as Nine Man Morris, Mill, Mills, Merels, Merelles, and Merrills.

The Nine Men's Morris board consisted of three squares each with eight spots connected to form an inner square, middle square and outer square; total of twenty-four spots. Each player then placed their nine pieces, or “men” onto the board, which move among these spots. Whoever has fewer than three pieces or been immobilized loses the game.

Placing Men:
Players alternate turns placing their pieces on empty spots. If three pieces of the same side formed a straight row along one of the board's lines, a “mill” is formed. Player who forms the “mill” may remove one of his opponent's pieces from the board; once removed, they cannot be placed again. Pieces from a formed mill cannot be removed unless there are no other pieces left to remove. After all eighteen pieces have been used, players start moving the pieces.

Moving the Men:
A player can slide one of his men along a board to any empty adjacent spot. If he cannot do so, he loses the game. If three pieces of the same color formed a straight row along one of the board's lines, a “mill” is formed. Player who forms the “mill” may remove one of his opponent's pieces from the board. Pieces from a formed mill cannot be removed unless there are no other pieces left to remove.

Flying:
If a player is left with three pieces, his pieces gain the ability to “Fly” to any vacant spot on the board.
