Three Men’s Morris

Three men’s morris is an abstract strategy game played on a three by three board (counting lines) that is similar to tic-tac-toe.



Each player has three pieces. The winner is the first player to align their three pieces on a line drawn on the board. There are 3 horizontal lines, 3 vertical lines and 2 diagonal lines.

  • The board is empty to begin the game, and players take turns placing their pieces on empty intersections. 
  • Once all pieces are placed (assuming there is no winner by then), play proceeds with each player moving one of their pieces per turn. 
  • A piece may move only to any adjacent empty position. 

There is an alternative version in which pieces may not move to an adjacent position, but to any vacant position that is not adjacent.

Here is the Google Slides version.
