Today’s optical illusion is a little trickier than the rest of the days. Apart from testing your eyes, we are also interested in knowing how much focus and concentration you have, which can enhance your cognitive skills as well, apart from seeing your attention to detail.

Optical illusions usually help challenge how you see the world. Apart from shifting shapes to puzzling patterns and even interesting visual riddles to find the odd one of missing pieces, these reveal how your brain may interpret what your eyes see or what is missing.

In today’s task, you can clearly see a colourful representation of a chaotic grid of consecutive numbers—the shades of red with 43 and green with 42. However, there is a hidden visual maze is an impostor - a rogue number that's not like the rest.

You have to spot the number 23 among the rows of 42s and 43s as quickly as you can!

While at first glance, the image would appear to be deceptively simple, as there are many large, cartoon-styled 42s and 43s that dominate the screen. And your eyes would quickly jump from one digit to another; however, the subtle pattern quickly begins to blur, and that is what the task is all about. You need to search for the anomalies and analyse shape patterns along with filtering colour differences to find the correct answer as quickly as you can.

This illusion is not just fun but also a way to help you tap into your visual discrimination skills, the same abilities you use every day to read signs, identify people, or notice small changes in your environment. Spotting the number 23 amidst a sea of lookalike numbers requires your brain to override automatic recognition and actually examine each element carefully.

So, were you able to do it?

Move your eyes toward the bottom-left section of the image. Somewhere in the second row from the bottom, the fourth number from the left—you will be able to spot it. A sneaky 23 is camouflaged in red.

However, if you are still struggling, do not worry. Experts say that in visual perception, illusions like this trick the brain because they tend to group similar shapes and overlook tiny differences when patterns are consistent. Human brains are wired to make quick decisions and fill in gaps when presented with repetitive visual information. In this image, the colours and shapes are so similar that the brain defaults to assuming all numbers follow the same pattern—unless you consciously slow down and focus.

Illusions like these don’t just entertain—they train our brains to resist shortcuts and sharpen focus. Many psychologists also use such puzzles to measure attention span, reaction speed, and even early signs of cognitive decline.

For most people, spotting 23 should take anywhere between 10 t 20 seconds. However, if you took longer, do not be disheartened.

Brain teasers are a way to train your brain and enhance focus and concentration, not to pass any test.

If you regularly solve visual puzzles, you may be able to improve your memory, process speed, and visual acuity over time.
