When you have completed an exercise and click “Pause”, you can continue analyzing the game by clicking the “Show game” button.

This opens an editable version of the game on which the exercise is based, allowing you to examine why certain ideas do not work and to see how the game actually continued. When you save the game, your analysis remains private—it is not shared with others who may solve the same exercise.
If you later solve the same Woodpecker exercise again and click “Show game", your saved analysis will open, so you can continue working from where you left off.
