Nine Men’s Morris is a two-player strategy board game. The game has three clearly delimited phases:
- Phase 1: Placing pieces
- Players alternatively place their pieces on the board. If a player closes a morris (or mill), she will grab one of her opponent’s piece. Strategically placing the pieces is more important than closing a morris in this phase.
- Phase 2: Moving pieces
- Players alternatively move their pieces one at a time to an adjacent empty point, close morrises and grab pieces.
- Phase 3: Flying pieces
- A player reaches phase 3 when she is left with only 3 pieces. She can now move any of her piece to any empty point on the board.
A player wins by reducing her opponent to two pieces, or by leaving her without a legal move.
