The aim of the game is to tap the yellow dot as many times as possible in three time categories: 3, 5 and 10 seconds. Select the category and when you start tapping, the time will automatically begin counting down to zero. Total number of taps will be displayed at the end of selected time.Seems easy? It is at first glance but, when you think that one can tap more than 10 times a second, only then you realize that the game starts being challenging and fitness plays a big role in it.Tips that I can give you are: Use the outer side of your thumb to tap. In order to generate high frequency use the muscle of your forearm together with biceps and triceps.
