Tic Tac Toe
🎮 Click / tap squares, or number keys 1–9.X's, O's and one unbeatable robot. The three-in-a-row classic — now with a minimax AI you can actually beat (sometimes).
How to play
- Tap any square (or press keys 1–9) to place your X — you always start.
- The computer replies instantly with strong play; line up three in a row — across, down or diagonally — to win.
- Switch to 2-player mode to pass and play with a friend on the same screen.
Frequently asked questions
Can you beat the computer at Tic Tac Toe?
Our AI plays near-perfect minimax strategy with a small dose of randomness — it never falls for the classic double-threat traps, but it leaves the door open just often enough. About one in five games is winnable with sharp play.
Is Tic Tac Toe solved?
Yes — with perfect play from both sides, Tic Tac Toe is always a draw. That's why the interesting question is spotting your opponent's mistake first, and why our AI deliberately isn't 100% perfect.
How do I always win Tic Tac Toe?
Against imperfect opponents: take the center first, then create a fork — two threats at once. A fork forces a loss because your opponent can only block one line.
Is it free and private?
Completely. The game runs in your browser with no sign-up, no ads inside the board, and nothing is uploaded — scores reset when you leave.
