Frequently Asked Questions
How do I play Tic-Tac-Toe?
Two players take turns placing marks on a 3×3 board; the first to line up three in a row (horizontal, vertical, or diagonal) wins.
Can I play against the computer?
Two-player local mode and single-player AI mode are supported, with a choice of who goes first.
Can you always win at tic-tac-toe?
No. With perfect play from both sides the game is always a draw, which is why the computer can hold you to at best a tie in single-player mode.
How strong is the computer opponent?
It plays sensibly: it takes winning moves, blocks yours and prefers center and corners, so casual players will lose most games they do not defend carefully.
