This reddish cluster has so disturbed your gaze that you have not been able to detect the number in question? Look at the picture again: if you look carefully, in the foreground you will see the presence of three main forms. Of course, this is barely noticeable, but you can see the number 571.

If you have failed this visual challenge, don’t worry. There are many such tests on the Internet that will help you train to improve your cognitive skills. Intelligence tests are divided into two categories, those for children and those for adults. To achieve the desired results, start by simplicity until you reach complexity.
