Title: great, except for the booster code
Review: My son got this for his 4th birthday, and he loves it. It's alot like Incredible Machine, which was a really fun game. He plays it all by himself and has beaten almost every level. The booster code thing is quite lame, and of course young children might feel bad not getting to play part of their game. I think the game is quite nice without the extra free play levels, and I would recommend it for advanced preschoolers to much older kids. My husband and I got into a debate over which items to use on one of the levels. Lots of fun!
