Tic-Tac-Toe overview
Tic-Tac-Toe is a quick 3 × 3 strategy game where X and O take turns claiming empty squares. Build a horizontal, vertical, or diagonal line of three before your opponent in computer, local two-player, or online-room play.
Controls and modes
Tap or click an empty square to place a mark. Choose Vs Computer, 1v1 Local, or Online Room; online players can create or join a room and send preset quick-chat messages.
Strategy tips
- Check for a winning move before considering anything else.
- Block any opponent line that already contains two marks.
- The centre participates in four winning lines, making it the most flexible opening square.
- Use opposite corners to create two threats at once, often called a fork.
Tic-Tac-Toe questions
Who moves first?
