How to playThree in a row — horizontally, vertically or diagonally. That's the whole game.
1Pick your markYou play X, the engine (or your friend) plays O. Black moves first in every match.
2Place one per turnClick an empty cell. Each move locks immediately; no take-backs, no time bank.
3Block and strikeIf you only chase your own line, you lose to a fork on the next turn. Think one move ahead.
