Zap is a super challenging fast game where, simply enough, you are just a green frog trying to catch some flies! Test your visual reaction time and then test your hearing reaction time. In the first trials, click the button with your mouse as soon as you see the fly on the radar screen. In the second round of trials, click the button as soon as you hear the fly. All of the trials will be added together to tell you just how fast you really are. Feed the hungry frog on time in this fun fast game!
