Possibly the most simple game ever, and a perfect time waster. Described by one fan as "the perfect game for playing on the loo."
Just tap the circle. The larger it is the more points you get. But be careful, it can pop at any time, and has a different maximum size every time it starts to grow.
Start out on the Beginner Level where there is a guide to show you the danger zone. Then when youre ready challenge for the Hard Level high score, but beware, its brutal.
Have fun and chase those high scores!
