Test your fast thinking skills in this original game! In order tomake high scores you have to be quick and think at least 2 stepsahead! Have fun and try to beat my high score of 186!-------------------------------------------------------------------------------How to play: click on the circles when they change color from greyto some other (red, blue...). It will happen after they pass thegrey circular. But you have to click them before they reach fullsize! One mistake and it's game over!
