How to play
- You are X and always move first — click or tap an empty square.
- Line up three of your marks across, down or diagonally to win the round.
- Win and the board clears for the next round, keeping your streak.
- A loss or a draw ends the run — the streak you reached is your score.
- Difficulty is how often the computer moves at random: Easy 80%, Medium 35%, Hard 10%. The rest of the time it searches the whole game and plays perfectly.
- Played perfectly by both sides the game is always a draw, so winning means punishing a slip before the computer recovers.
- Each difficulty keeps its own leaderboard.
