How to Play — Nine Men's Morris

Mühle (also known as Nine Men's Morris, Mills, Merels, or Morris) is one of the world's oldest two-player strategy games. The board has 24 intersection points (where lines meet), and each player starts with 9 pieces ("men"). The goal is to reduce your opponent to fewer than 3 pieces, or to leave them with no legal move.

A game has three phases. The phase you're in depends on how many pieces you have left.

Phase 1 — Placing

Players take turns placing one of their 9 pieces on any empty intersection on the board. Placing continues until both players have placed all 9 pieces.

If you complete a row of three of your own pieces along one of the board's lines — called a mill — you remove one of your opponent's pieces from the board. You cannot remove a piece that is already part of an opponent's mill, unless no other pieces are available.

Phase 2 — Moving

Once all pieces have been placed, players take turns moving one of their pieces along a line to an adjacent empty intersection. You cannot jump over other pieces or move diagonally where no line connects.

Forming a new mill — either by sliding a piece into position, or by breaking an old mill and re-forming it later — again lets you remove one of your opponent's pieces.

Phase 3 — Flying

When a player is reduced to just 3 pieces, they enter the "flying" phase. On their turn, they may move any of their pieces to any empty intersection on the board, not just an adjacent one. This is a final chance to escape losing positions and form new mills.

Winning the Game

You win when your opponent is reduced to fewer than 3 pieces, or when they have no legal move available on their turn.
