How to play
Nine Men's Morris has three phases: 1) Placing — each player places 9 stones alternately on the intersections. 2) Moving — stones move to an adjacent empty point. 3) Flying — when you have only 3 stones left, you may fly to any empty point. Three in a row (a mill) lets you remove an opponent stone. You lose when reduced to 2 stones or can't move.
Tips & Tricks
Tip: In the placing phase, the T-junctions (b4, d2, d6, f4) are gold — they have four connections. Plan for a double mill (Zwickmühle): a stone alternating between two mills, capturing every move.
