Tic Tac Toe Offline

Tic Tac Toe Offline is the classic pencil-and-paper game of X and O, made for quick rounds on your phone. Play against a computer opponent with three difficulty levels or pass the phone to a friend for a two-player match on one device. Everything works without an internet connection and without creating an account.

Pick the Easy opponent for a relaxed game, Medium for one that blocks your threats but still slips up, or Unbeatable for perfect play on the 3×3 board where a draw is the best anyone can do. Choose whether you play X or O and who makes the first move; after each round the starting player alternates automatically so rematches stay fair.

Want more room to think? Switch to the 4×4 or 5×5 board. On 4×4 you need four in a row; on 5×5 you need four in a row anywhere on the board, including the shorter diagonals. The rules are shown on screen before every game.

Your unfinished match is saved automatically, so you can close the app and continue later. Local statistics track wins, losses and draws for every mode and difficulty, your win rate and your longest winning streak against the AI.
