Think your observation skills are razor-sharp? Our today's optical illusion test challenges you to spot the hidden number “3” among a sea of “B” and “O” letters made of brown fur. But be warned – only 1 per cent of people with eagle-eyed vision can find it without zooming in or squinting.

The brain teaser features rows upon rows of repeating “BO” patterns. At first glance, it appears monotonous and easy to skim through – but somewhere within this cleverly crafted grid is the elusive number "3". Blended almost seamlessly into the image, the trick lies in how closely the “3” mimics the appearance of a “B”. The design exploits how our brains are hardwired to look for familiar patterns and skip over minor discrepancies – a phenomenon often referred to as "cognitive shortcutting."

Can You Spot the Hidden 3?

Before you scroll down or give up, take a moment to really scan the image carefully. The illusion is designed to test not only your visual perception but also your patience. According to cognitive psychologists, puzzles like these are more than just fun – they actually stimulate parts of the brain responsible for attention to detail, problem-solving, and spatial reasoning.

Let’s put your vision to the test. Ready? Set a timer for 10 seconds and try to find the number “3” in the image. If you managed to find it in under 10 seconds, congratulations – you’re in the top 1% with laser-like focus and superior visual acuity! But if not, don’t worry. You’re not alone.

Here’s the Reveal

For those still squinting: the hidden “3” is located in the fourth row from the top and the fourth column from the left. Unlike the other characters in the puzzle, which alternate consistently between "B" and "O", this sneaky “3” has been styled to mimic the furry texture of the other letters. Its placement and design play tricks on the brain, causing most people to overlook it on their first – or even second–try.

Why Optical Illusions Fool Us

Optical illusions like this one demonstrate how our brains interpret what our eyes see. According to Dr Carlene Johnson, a neuroscientist specialising in perception, “Our brains are constantly trying to make sense of what we’re seeing by matching it to existing patterns and expectations. In this illusion, the repetition of the 'BO' pattern causes our brain to predict what’s coming next, so it often skips over the anomaly — in this case, the '3'."

This is part of a broader psychological effect known as “inattentional blindness,” where people fail to notice unexpected objects in plain sight because their attention is focused elsewhere.

The Rise of Visual Brain Teasers

These kinds of puzzles have surged in popularity on social media platforms and news sites alike, often accompanied by claims that “only geniuses” or “those with a high IQ” can solve them. While they’re not necessarily a measure of intelligence, they are great tools for mental stimulation and visual acuity training. And let’s be honest – they’re also a lot of fun!

Experts even suggest incorporating brain teasers like these into your daily routine to sharpen mental alertness. It’s like a gym workout for your eyes and mind.

Whether you spotted the “3” instantly or took a little longer, engaging with optical illusions like this one offers more than just a few moments of entertainment. They push your brain to think differently, test your limits, and remind you of the joy in solving even the smallest mysteries.

So, the next time someone says “you’ve got an eagle eye,” you might just believe them—especially if you found the hidden "3" without breaking a sweat!
