Tic-Tac-Toe is the classic three-in-a-row game on a 3 × 3 grid. Two players take turns placing X and O, and the first to complete a row, column, or diagonal wins. When the grid fills up without a line, the game is a draw.
Play a friend on the same phone or computer, or play the computer. Easy mode picks any free square, while Unbeatable plays perfect moves, so the best you can do is a draw.
Can I beat the unbeatable computer?
No. It plays perfect moves, so the best result against it is a draw. Easy mode chooses any free square and can be beaten.
Is my score saved?
The score lasts while the page is open and resets when you reload or change the opponent. Nothing is uploaded or saved.
Can I play with the keyboard?
Yes. Move between squares with Tab or the arrow keys and press Enter or Space to place your mark.
Can I play online against someone else?
No. Friend mode is for two people sharing one device; there is no online multiplayer.
