Raise your hand if you’ve never enjoyed challenging yourself with visual puzzles and optical illusions. The internet is full of them: some are simple, while others are more complex and cause a lot of confusion for those who view them. These visual challenges are not only fun but also give us information about our perceptual skills and how well we can distinguish details in a busy background. The internet is packed with these tests, and they continue to spread because they are exciting and challenging.

The image we are showing you definitely belongs to the optical illusions category. It has prompted many questions, comments, and answers. At the center, you see a circle consisting of black and white stripes, arranged in a confusing manner. Take your time to look: what is clear at first glance to one person can be completely different to another. Are you ready to study this carefully and answer our question?

So, what do you see within this circle? Yes, you guessed it: there are numbers. So far, nothing special, but the real questions are: how many numbers do you see? And what exactly are they? Can you identify them all correctly? This is a typical image that seems simple at first, but requires much more time and concentration than you would expect.
Besides the fun aspect, this visual game gives us the chance to gain more insight into our visual abilities. To distinguish the exact numbers amid the jumble of stripes, you need a good sense of contrast. Not everyone who responded could recognize the correct numbers in the image. Some people saw two, others three, or even more.
