How to play

Black starts. Bracket a straight line of opponent discs between a new and existing disc to flip them all. Every move must flip a disc. No legal move means an automatic pass. When neither side can move, the larger disc count wins.

Good to know

Corners are stable anchors. Restrict your opponent’s next moves rather than only counting discs. The practice AI does not guarantee optimal play.

A move beside an empty corner can give that corner to your opponent. The last move is outlined on the board.

Play without signing in or submitting a score.
