free to use and take, just credit (jk idrc if you credit or not) so how it works, is you wait for the blue circle countdown to hit 0, then you click as much as possible until you hit the number 10 (please no auto clicker). it will tell you how many times you clicked, and how many clicks you can do in a second (CPS is Clicks per Second) This engine may be used in Earth Clicker in the future.
