Free Online Tic-Tac-Toe
The classic game of tic-tac-toe (also known as noughts and crosses), now free online. Play against the computer with three difficulty levels — easy, medium, or hard, where the computer uses the minimax algorithm and never loses — or play with someone else on the same device, taking turns. Every rematch automatically alternates who goes first to keep things fair, and your stats (wins, draws, losses, and your best streak) are saved in your browser so you can track your progress game after game.

Questions about Tic-Tac-Toe
Can you beat the computer on hard mode?
No. On hard, the computer uses the minimax algorithm and calculates the perfect move every turn, so the best you can do is draw. On easy and medium it does make mistakes and can be beaten.
Can I play with a friend?
Yes, switch to '2 Players' mode to take turns with another person on the same device, no computer involved.
Who goes first each game?
The first game starts with X. Every time you hit rematch, who moves first automatically alternates, so neither player always has the advantage of starting.
