How to play Tic-Tac-Toe
- Choose Me vs computer or Two players on the introduction screen.
- Select an empty square. The computer takes its turn automatically in solo play.
- Watch for both immediate threats and opportunities to build two lines.
- Win or draw to advance in solo play. Higher levels require consecutive cleared rounds.
Tic-Tac-Toe tips for your next round
- Check whether either player can finish a line on the next move before building a longer plan.
- The center participates in four lines; corners can help create two threats at once.
- Against the expert opponent, a draw is a successful clear. You do not have to force a win.
Does a draw unlock the next Tic-Tac-Toe level?
Yes. A draw counts as a cleared round. Higher levels require two or three cleared rounds within the challenge.

Controls and accessibility
You play X against the computer. Or choose Two players and take turns on this screen.
Squares have numbered accessible names and announce their symbols. A draw counts as a clear, so an expert round can be completed without beating the opponent.
Display settings provide higher contrast, larger text and reduced optional motion. Keyboard focus indicators remain visible. These features are not a claim of complete accessibility for every game.
