XO Game

XO Game brings the familiar Tic Tac Toe contest to a three-by-three grid. You play as X against O, either controlled by a friend or by the computer, and every move can change the chance of forming a winning line.

The aim is to place three of your marks in a row vertically, horizontally, or diagonally. A full grid ends the game when nobody has won, so careful choices matter even in this small playing space.

Tap an empty square on the game screen to place your X.

Watch where O appears and consider both your next line and the opponent's possible line.

Try to connect three X marks across, down, or diagonally before O does.

If all nine spaces are filled without a line, the round finishes as a draw.
