This is a fast reaction game. It starts with a collection of squares, half of them in white. The objective of the game is to achieve that all the squares become white. Play against the machine and tap the yellow button before it disappears to win a white square, otherwise you will lose one. Test yourself and find out your reaction time.
You'll be able to compare your tap time with your friends and to expose who is the faster taper.
