How to play
Take X against a computer that looks for wins and blocks your immediate threats. Control the center and build a line of three.
- Tap an empty square. The computer plays O after every move.
- Get three X marks in a row, column or diagonal. A full board without a winner is a draw, not a successful win.
- Your best stays on this device. Share a seeded challenge with a friend; a solved run beats an unfinished run, then points and time decide.
