About Tic-Tac-Toe

Tic-Tac-Toe (also known as noughts and crosses) is the quintessential pen-and-paper strategy game. Play as X against a smart computer opponent that blocks your winning moves and pounces on its own. Line up three of your marks in a row — horizontally, vertically or diagonally — before the AI does. Quick to learn, satisfying to master.

How to Play

1. 1You are X. Tap any empty square to place your mark.
2. 2The computer (O) takes its turn automatically.
3. 3Get three of your marks in a row — across, down or diagonally — to win.
4. 4Block the computer from making its own line of three.
5. 5Tap after the result to play again.

Tips & Tricks

• Take the center square whenever it's open — it's the strongest spot.
• Corners are stronger than edges; grab them early.
• Always block the opponent's two-in-a-row before building your own.
