FAQ
How do you play Nine Men's Morris?
Players take turns placing their 9 pieces on the 24 points (the placing phase). Once all pieces are placed, you move one piece per turn to an adjacent empty point along a line (the moving phase). Three in a row, across or down, forms a mill and lets you remove one of your opponent's pieces. You win when your opponent is down to 2 pieces or can't make any move.
Are there pieces I can't remove?
You can't remove an opponent's piece that is part of a mill (three in a row) — unless all of their pieces are in mills, in which case you can take any of them.
What does "flying" mean?
A player with only 3 pieces left can move a piece to any empty point, not just an adjacent one. It gives the losing side a chance to come back, and on this board it applies to both players.
How strong is the computer?
It looks 3 turns ahead and scores positions by piece count, mills, two-in-a-rows that threaten a mill, and mobility — about intermediate level. Its play changes a little every day, and on the same day it always answers the same moves the same way.
How is the leaderboard ranked?
Only wins are recorded, scored as 200 minus your number of turns. Highest score first; ties go to the shorter time. Games that drag on (60 turns, or 30 turns without a mill) are stopped as a draw. The server replays your game, including the computer's replies, to verify it.
