Step by step

Connect 4 calculator analysis: the move played loses, while the solver's suggestion in the next column wins
Find the move where the score dropped.
  1. After a game, open the solver and click the columns in the order you played.
  2. Step back through the moves one at a time.
  3. Watch the score. The move where it drops from winning to losing, or from drawing to losing, is your mistake.
  4. Look at what the solver suggests instead, and work out why it’s better.
  5. Play the position again against the computer to practise.
