All you have to do is tap!
Test your reaction with ready set tap, an easy to grasp but hard to master game. Watch the timer on your screen increase and be ready to tap the quarter of the screen that lights up green. Tap too slow... you lose! Tap the wrong quarter... you lose! Infuriatingly addictive.
