You are X. Tap a square — the Hard computer is unbeatable, so aim for a draw.
How to play
- You play as X; the computer plays as O.
- Tap any empty square to place your mark, then the computer takes its turn.
- Get three of your marks in a row — across, down, or diagonally — to win.
- Choose Easy for a beatable opponent or Hard for a perfect AI you can only draw against.
Strategy & tips
- Take the centre when you can — it is part of the most winning lines.
- If you go second, grab a corner rather than an edge.
- Create a "fork" — two ways to win at once — so your opponent cannot block both.
- Always block the computer when it has two in a row, or it will win next turn.
- Against the Hard AI, perfect play leads to a draw; look for a slip only the Easy AI will make.
