Well to be honest Plastic Balls is not really a puzzle game, put in my opinion you at least need to figure out how to get to the next level.
Plastic Martians developed Plastic Balls and can be seen as a circlular version of Arkanoid. Do you still remember that one? I still have the list for each level on which side to exit to have a less difficult level. You can play five levels of Plastic Balls for free online.
If you want more you will have to buy the full version. Happy Puzzling!
