Tic Tac Toe IO is a modern version of the familiar 3x3 square game, with a vivid and attractive 2D design style. The game takes place on a 3x3 board. Players need to arrange 3 consecutive X or O symbols horizontally, vertically, or diagonally to win.
You can choose to play with the computer, challenge your friend, or join online matches with players from all over the world.
With 2-player mode, you can play with friends or compete with online players. The matches are fast, attractive, and require you to have good tactical thinking and judgment.
Use the mouse to play:
Move the mouse cursor to the square you want to hit.
Left click to place X or O (depending on your turn).
Touch screen:
Touch the square you want to place the symbol in.
Your mark (X or O) will be displayed immediately.
Try Paint io or Taming io — they’re a little more fun and worth a try!
