Amazing Alex (for iPhone)

Meet Alex, your "amazing" school-aged protagonist with a penchant for turning objects into physics games. He isn't actually in the game, but challenges are set in his classroom, bedroom, backyard, tree house.

In each challenge, your goal is to collect the three stars located in every challenge board by hitting them with various objects.

The first nine levels are so are so easy they get boring. Dotted lines and arrows show you exactly where to place objects to create the perfect Rube Goldberg design. After that, however, the challenges lose their prompts and the game becomes wildly addictive.

After you pass the classroom level (containing 16 challenges), the app unlocks a fifth level, My Levels, where you can create your own challenge boards and share them with the Amazing Alex community.

For $0.99 you get 100 challenge boards, but also the chance to download new levels from Rovio as they are released.
