Tic Tac Toe

Play Tic Tac Toe online, free, no account

The classic 3x3 grid game, playable against a local computer opponent or with a second person sharing the same device. Every move is worked out on your own machine, so there is no matchmaking wait and nothing to sign in for.

How to use it

1. Choose single-player to face the computer, or multiplayer to pass the device between two people.
2. Pick X or O, then click any open square to place your mark.
3. Line up three marks in a row, column or diagonal to win the round.
4. Start a new round instantly, no reload needed.

Frequently asked questions

How strong is the computer opponent?

It plays every move deliberately rather than randomly, so it will punish an obvious mistake and rarely loses a winnable position. It is a genuine opponent, not a placeholder that simply picks empty squares.

Can two people play on the same device?

Yes, switch to multiplayer mode and take turns tapping or clicking the board. There is no online matchmaking, so both players need to be at the same screen.

Is my score saved?

No. The current round is tracked while you play, but nothing is written to storage, so scores reset if you reload or close the tab.

Does it work on a phone?

Yes. The board responds to taps the same way it responds to clicks, and needs no keyboard.
