With the help of the exciting new game Circles Target, you can test your attentiveness, accuracy and reaction speed. You will do this by shooting from a cannon. In front of you on the screen you will see a playing field on which a circle will be depicted. There will be a cannon at a certain distance from it. It will rotate in space at a certain speed. You will have to guess the moment when the muzzle of the cannon will be directed at the circle. When this happens, just click on the screen with the mouse. Thus, you will fire a shot and if your scope is accurate then the cannonball will hit the target. This hit will bring you a certain number of points. If you miss, you will fail the passage of the level.
