About This Game

A familiar pencil-and-paper duel gets a polished digital upgrade with boards stretching from the traditional three-by-three grid all the way to sprawling eight-by-eight arenas. Take turns claiming spaces against a computer opponent or a friend sharing your screen, lining up your marks before your rival completes theirs. The classic size rewards perfect play with tense draws, while larger boards open wild strategic territory where early positioning decides everything. Quick rounds make it ideal for settling scores anywhere, anytime, with anyone.

How to Play

Click an empty square with your mouse or tap one on your touchscreen to place your mark. Alternate turns with your opponent, trying to complete a straight line before they manage the same. Select the board size before starting, from the classic three-by-three up to a huge eight-by-eight. Larger grids need longer lines, so check the rule for each arena.
