Rule number one: Click the correct color, which you see in big box, among four little boxes! There is no second rule :)
You will win 1 point for every correct click and you will lose 1 point for every wrong click.
The faster you click the higher points you get in 25 seconds!
In arcade mode things are getting a little complicated, little boxes of FOUR COLORS will occur at random order.
If you fail restart session, try for the best result and share with your friends.
HAVE FUN!
