Tic Tac Toe (Noughts and Crosses)

Tic Tac Toe, also called Noughts and Crosses, is a quick game on a 3 by 3 board. Share an invite link to play online with a friend, take turns on one device, or choose the computer at Beginner or Advanced level. Free, with no sign-up.

How do you win?

X moves first. Take turns placing X and O in empty squares. Three of your marks horizontally, vertically or diagonally wins. A full board without a winner is a draw.

Another round?

Choose “Play again” after a result. Online, both players must accept. The score carries over and sides switch by default; tap the next-side line to change them.

How to play

  1. Share an invite link or let your friend enter your 6-character room code. You can also play together on this device or choose the computer at Beginner or Advanced level.
  2. X moves first. Take turns placing your mark in an empty square.
  3. Three marks in a horizontal, vertical or diagonal line wins. A full board without a winner is a draw.
  4. On a phone, tap once to preview, then tap the same square again to place. Use Tab or arrow keys to choose a square, then Enter or Space to place.
  5. Undo and Resign sit below the board. Online Undo needs your friend’s approval. On one device it reverses one move; against the computer it reverses your move and the reply. Finished games cannot be undone. Resign gives your opponent the round.
  6. Choose “Play again” after a result. Online, both players accept and sides switch by default; the score carries over.
  7. Progress is saved in this browser. Return here to try to resume after a refresh or disconnect; online recovery needs both players to reconnect. Changing devices or clearing browser data can prevent recovery.

Returning to a game

Progress is saved in this browser. For an online game, use the room link in the same browser; both players need to reconnect. Changing browsers, clearing browser data or an expired room can prevent a return. There is no cloud backup of your game.
