Bop and Pop the bouncing balls to score, but don't get too greedy by trying to pop all the balls at once. Collect power ups like extra nodes to be able to pop more than one ball at a time, and avoid nasties that will try to complicate things or make you loose your lives. Keep playing to top your own scores.
* NOTE: there is also a paid (add-free) version of this game; though they are functionally the same app, they are different programs and run independently of each other and do not share data between them. If both versions of the game are installed on the same device, the scores of one version will not appear in the other version.
