In the new Clock Challenge, you can test your attentiveness, dexterity, and reaction speed. Before you on the screen there will be a playing field on which the watch dial will be visible. There will be an arrow in it, which will run in a circle gradually gaining speed. Numbers will appear in various places on the dial. When the arrow stands in front of one of the numbers you will have to click on the screen with the mouse. Then the number will disappear from the screen and you will be given a certain number of points for this.
