The clock is moving very quickly and in a really odd method! All you need to do is to match the color of the clock's hand with the circle around it by clicking on the screen on the right time. It might appears easy, but the clock will move much faster and much faster as you progress and it changes color and instructions after every effective match. You will lose if you do not click on the correct time or you match the incorrect colors. So focus and attempt to earn as much score as you can!
