About Tic-Tac-Toe

Play Tic-Tac-Toe online free against a smart computer opponent. You are X and move first — race the bot to line up three marks in a row. Quick, classic, and playable on phone or desktop with no download and no sign-up.

How to play

The bot plays perfectly, so against it a draw is the best you can force — treat every draw as a win. Take the centre or a corner on your first move, and always watch for the double threat, where one mark creates two winning lines at once.
