Tic-Tac-Toe: a quick playing guide
You play X and move first. Take turns with the computer placing marks on a three-by-three board. Make a horizontal, vertical or diagonal line of three to win. A full board without a line is a draw. Different difficulty settings change how the computer chooses its move rather than changing the rules of the board.
How do you control Tic-Tac-Toe?
Click or tap an empty square to place X. The computer places O after your move. Use New game to start again. Keyboard users can select empty square buttons with Tab and Enter.
What should a beginner try?
Check for an immediate win or block before choosing a square. The center and opposite corners can help create multiple threats.
