We got this puzzle for my daughter's third birthday because she is crazy about carnivals and had just begun to show an interest in many piece puzzles. At first I thought it might be too hard for her but after a day or two she could quickly assemble it. She recites the clues she uses to put it together as she goes along and when it is completed we use the cardboard children as little dolls and walk them through the fair. Plenty of other small creatures from her collection visit the completed puzzle and make their way down the winding paths to the various rides and games. Yes, the carousel often comes apart but that enables other toys to have a spin on it. I give this five stars as it is entertaining on its own and expands to include other creative possibilites.
