Setup

  • The board has three nested squares joined by four lines, giving 24 points to play on.

How to play

  • When all nine are placed, move one of your stones along a line to a neighbouring empty point.
  • When three of your stones stand in a line (a mill), remove one of your opponent's stones. Stones in a mill are safe unless every one of the opponent's stones is in a mill.
  • Open a mill and close it again on a later turn to capture again.
  • With three stones left, you may fly a stone to any empty point (this can be turned off in the settings).

Winning
