The game which consists of 14 levels analyzes your actions and offers up the next level when, which, according to its logic, you will be able to master it. On some levels the ball will change size, on some it will be magnetic to the iron girders, and at some point you will have to remember a nursery rhyme about a rainbow to complete that level. How far you advance is up to you.
