Rules

  1. Each of the two players uses 'X' or 'O' as a token, and they take it in turns to occupy available squares.
  2. Each row or column of three occupied squares (in a straight line) scores a point.
  3. The winner is the player with the most points when all available squares have gone.
  4. The most central square gives too much advantage and is not available to either player.
