About Nine Men's Morris

Nine Men's Morris is the classic mill game: each player places nine stones on a board of three nested squares linked by mid-side lines. Form a mill — three of your stones in a straight line — and remove one enemy stone. After all stones are placed, slide along the lines; when you are down to three stones, you may fly to any empty point.

This board runs the full place → move → fly cycle with mill captures, undo, hints, and three AI levels. Share one device for a same-screen duel, open an online friend room with an invite link, or challenge the computer when you want a quiet puzzle of forks and blocks.

How to play Nine Men's Morris

White places first. Each side has nine stones. The goal is to leave the opponent with fewer than three stones, or with no legal move.

1. Placement: take turns putting a stone on any empty point until both sides have placed all nine.
2. Whenever you complete a mill (three in a straight line on the board graph), immediately remove one opponent stone that is not in a mill — unless every enemy stone is in a mill, in which case any may be removed.
3. Moving: once placement ends, slide a stone along a line to an adjacent empty point. Mills still capture the same way.
4. Flying: when you have exactly three stones left, your stones may jump to any empty point on your turn.
5. You win when the opponent has fewer than three stones on the board, or cannot make a legal move.

Nine Men's Morris strategy tips

• Early mills matter less than controlling junctions where several lines meet — especially the mid-side points of the outer square.
• Avoid clustering all stones into one mill; a broken mill that can re-form next turn is a lasting threat.
• When the opponent threatens two mills at once, you usually cannot block both — create your own double threats first.
• In the flying phase, think two jumps ahead: empty a point that completes your mill while breaking theirs.
• Hard AI punishes loose placement; use a hint when a capture choice looks equal but is not.

Nine Men's Morris FAQ

What is a mill in Nine Men's Morris?

A mill is three of your stones in a straight line on the board graph — along an outer, middle, or inner side, or along a radial mid-side link. Completing one lets you remove an opponent stone immediately.

When can stones fly to any point?

After placement ends, if you have exactly three stones left on the board, each of your turns may move a stone to any empty point, not only an adjacent one. That is the flying phase.

Can I remove a stone that is already in a mill?

Only if every opponent stone is in a mill. Otherwise you must remove a stone that is not part of a mill, which keeps strong formations from being dismantled too cheaply.

Can I play Nine Men's Morris online with a friend?

Yes. Open Play with a friend, create a room, and share the invite link. The server validates every place, move, and mill capture so both sides see the same board — no account required.

How does the AI choose moves?

It searches ahead with a mill-and-mobility evaluation — favoring piece count, completed mills, and legal options. Easy mixes in random plays, medium rarely blunders, and hard searches deeper on both placement and movement.
