How to play Tic-Tac-Toe

Tic-Tac-Toe (also called Noughts and Crosses) is played on a 3×3 grid. You are X and the computer is O. Take turns placing your marks — the first to get three in a row, in any direction (across, down or diagonally), wins. If the board fills up with no winner, it's a draw.

Pick your difficulty: Easy plays random moves, Medium plays a decent game, and Hard uses a perfect strategy that can't be beaten — the best you can do is force a draw. Your running tally of wins, draws and losses is kept for the session.
