onlinegamesbrowser.comHow to play
Two players take turns marking empty squares, one with X and one with O. The first to get three marks in a line, across, down or corner to corner, wins. Nine full squares and no line is a draw.
- Under Play, choose Vs computer or 2 players.
- Against the computer, set the Level: Easy, Medium or Unbeatable. You play X.
- Tap an empty square to put your mark there.
- Get three in a row before the other side does, or block them so nobody can.
- You, Computer and Draws keep a running tally for this visit, and who starts alternates from game to game.
Controls
- Touch or mouse: tap or click a square.
- Keyboard: the number keys 1 to 9 map to the squares, reading left to right from the top row.
- New game clears the board.
Tips
- If you have two lined up and the last spot is empty, finish the line.
- Otherwise, check whether the other side has two in a row, and block it.
- Moving first, start in a corner. Moving second, take the center if it's free.
- Set up a fork, a single move that threatens two lines at once. Your opponent can only stop one.
FAQ
Can I beat the Unbeatable level?
No. It searches all the way to the end of every line of play, and perfect play from both sides always ends level, so a draw is the best result. To actually win, try Medium: it takes wins and blocks threats it can see, but forks can slip past it.
Can we play two players on one phone?
Sure. Select 2 players and pass the device between turns. X and O alternate, and the opening move swaps each game.
Can I play with the keyboard?
Yes. Click the game once, then press 1 to 9 to pick a square, counting across each row from the top left.
Can I play tic tac toe at school?
There's nothing to download or install, so it works in Chrome on a school Chromebook. The school's network still decides which sites load. If this one is blocked, ask a teacher or the IT team, and skip proxy or unblocker sites, which break school rules and often carry malware.
