There are three levels of difficult: 6, 12 and 24 pieces. Select a level and one of the four puzzles to assemble.
When a puzzle is finished, the illustration comes alive and is interactive. For example, the leaves comes alive in the puzzle with a child holding up an umbrella against the wind. Interact with the leaves by tapping on them and the wind blows, and the child and umbrella get blown off the page.
When all four puzzles are done, a fifth puzzle appears.
