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.
