How to play
- Pick the computer's difficulty (easy, medium or hard) and the match length: best of 1, 3 or 5.
- You're X in amber, the computer is O in blue. Take turns placing a mark on the 3-by-3 grid.
- Line up three of your marks across, down or diagonally to win the game.
- If the grid fills with no line, the game is a draw - it doesn't count and is played again.
- Who goes first alternates each game.
- First to win more than half the games takes the match: 1, 2 or 3 wins.
