Tips to get better at Tic Tac Toe IO
- Take the centre square if it is open. It sits on four possible lines, which gives you the most ways to win.
- Check the board after every opponent move. Two of their marks in a line means you must block the third square right away.
- Aim for a fork: place a mark so that you threaten two lines at once. Your opponent can only block one of them.
- Use these Tic Tac Toe IO tips against live players: if you cannot win, a draw is better than a loss, so prioritise blocking over attacking.
- Play at a steady pace. Real opponents make mistakes, and a calm read of the grid helps you spot them.
