Exercise "Counting Flying Circles" - Start

Just count the number of circles you see in the picture below and enter the result in the input box. Here the circles differ in diameter, color and speed, this will help you count them, mentally separating them into groups. If the circles are not positioned well, and you see that some of them go together at the same speed and in the same direction, click the "Refresh Page" button, or wait until, due to the difference in diameter as a result of impacts on the polygon walls, they increase the distance one from another.
