About this game
Play classic 3×3 or connect five on the bigger 9×9 board. Challenge three computer difficulties, share a device, or invite a friend to an online room.
How to play
Choose 3×3 to connect three, or 9×9 to connect five or more in a straight line. Horizontal, vertical and diagonal lines count. Tap an empty tile, or use arrows and Enter. In classic mode, keys 1–9 select a tile. X starts the first round; the starting mark alternates each round.
