It is unclear who first invented the game, Morris or Mills, as it was also called. But it is believed to have originated around the Bronze Age. These games were popular during the 18th century. Archaeologists have found Morris boards carved into church pews, on prison floors, and many other places. Our Three Men's Morris board is made of poplar wood and measures 4in x 4in. Each set includes a set of game rules, three light pegs, and three dark pegs.
