It's a fun ditty of a game, but like most free games... ad city. I'm going to use this review to give some helpful tips. If going through a third-party app (i.e Just Play) and are after coins, avoid playing after 5PM. If your field is mostly empty but are about to lose the game, the best strategy, though not always a winning one, is to horizontal your attack. The best attack overall is to trap your balls through 1 pixel opening so they bounce like crazy off the ceiling. Hope this advice helps.
