Optical Illusion Eye Test: Spot The Odd '8' In This Brain Teaser Full Of 5s And 2s
In our today's optical illusion, we bring you a mind-bending brain teaser that will test not just your eyes, but your concentration and attention to detail as well.
Optical illusions have a way of challenging how we perceive the world. From shifting shapes to puzzling patterns, these visual riddles reveal how the brain interprets what the eyes see—and often, what it misses. In this latest challenge, you're presented with a vibrant and chaotic grid of repeating numbers: the bold digits ‘5’ and ‘2’ in alternating shades of green and orange.
But hidden somewhere in this visual maze is an impostor—a rogue number that's not like the rest.
The challenge?
Find the number “8” among the rows of 5s and 2s as quickly as you can!
At first glance, the image appears deceptively simple. Dozens of large, cartoon-styled 5s and 2s fill the screen. Your eyes may jump from one digit to another, but the subtle pattern quickly begins to blur. That’s when the brain gets involved—searching for anomalies, analysing shape patterns, and filtering colour differences.
This illusion is more than just fun—it taps 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 “8” amidst a sea of lookalikes requires your brain to override automatic recognition and actually examine each element carefully.
So, did you find it?
Here’s a hint:
Move your eyes toward the bottom-right section of the image. Somewhere in the sixth row from the top, the third number from the right—you’ll see it. A sneaky “8” is camouflaged in green among its curvy cousins.
Still struggling? That’s okay! According to visual perception experts, illusions like this trick the brain because they tend to group similar shapes and overlook tiny differences when patterns are consistent.
Our 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 use such puzzles to measure attention span, reaction speed, and even early signs of cognitive decline.
How Long Should It Take?
For most people, spotting the “8” takes between 15 to 30 seconds. But if it took you longer, don’t be discouraged! These brain teasers are about training your brain, not passing a test. In fact, regularly solving visual puzzles may even improve memory, processing speed, and visual acuity over time.
