Frequently asked questions
When does the game end?
When neither player has a legal move, even if squares remain empty. The player with more discs wins; equal counts are a draw.
What do the hints mean?
Marked empty squares are legal moves for the current player. Computer difficulty searches 1, 3 or 5 turns ahead and considers position and mobility.
