I purchased this game for my 7-year-old girl, who has several other Leapster cartridges. While the educational material was not too easy nor too challenging for her, she became frustrated that she could not earn a certain "ticket" she needed in order to complete the final level (one section requires tickets earned during other section playtimes). I myself tried to get that specific ticket for her several times, and I wasn't able to, even after over an hour of MY playing for it.
Still, it was fun (yes, even for me!) and a big "must-have" for any "Incredibles" fan between 7 and 9 years old.
