How a mill works
Place three of your pieces on one marked line to form a mill. You may then remove one opposing piece, except a piece protected in a mill while another unprotected piece remains.
How to play
Each player places nine pieces in turn. After placement, move one piece along a marked line to a neighboring empty point. If you have exactly three pieces, this version lets you fly to any empty point. Forming a mill removes one opponent piece. You win by reducing the opponent to two pieces or leaving them with no legal move. A repeated position or 200-turn limit is a draw.
Frequently asked questions
What is a mill?
A mill is three of your own pieces occupying the points of one marked straight line. Diagonals do not count.
Can a piece in a mill be captured?
Normally no, while the opponent has any piece outside a mill. If every opposing piece is in a mill, any one may be removed.
When can I fly?
When you have exactly three pieces on the board, you may move one to any vacant point. With four or more, move only to a connected neighbor.
How does the computer play?
The computer uses only the visible board and legal moves. It looks for a mill or a way to block one, then chooses among available moves locally.
Is the game saved online?
No. If this browser allows local storage, the current match is saved on this device so you can resume or delete it. No account is needed.
Rules and limitations
This is a single-player, offline-style game against a simple local opponent, not online multiplayer. It uses a common nine-piece rule set; flying, repetition draws and move limits can differ between local variants. No tournament ranking or perfect-play claim is made.
