Winning and losing

You win by connecting four. On Hard the computer looks several moves ahead.

Tips and Strategies

  • The centre column gives you the most lines.
  • Watch for threes that are open at both ends.
  • Build two threats at once so the computer can only block one.
  • Pay attention to the squares above a threat: a blocked square can give the computer a winning move.
  • Use Undo to explore alternatives while you learn.

Game Variations

  • Easy, Medium and Hard computer levels, and the choice to move first or second.
