In our today's optical illusion challenge, we bring you a tricky brain teaser test to give your mind a workout! The image above seems simple at first glance — colourful tiles displaying the numbers 22 and 44. However, hidden among them is a single "42" that is waiting to be spotted.
The catch? Only 1 per cent of people are able to find it within 15 seconds! This isn't just about having good eyesight — it's a true test of your brain's ability to recognize patterns, stay focused, and detect subtle differences.

Why Are Optical Illusions So Fascinating?
Optical illusions aren't just fun puzzles; they also offer powerful benefits for your brain health. According to Dr. Megan Whittaker, a cognitive neuroscience expert, "Brain teasers like these train your brain to process information differently, improving cognitive flexibility, focus, and visual perception."
Research published in the journal Frontiers in Human Neuroscience supports this, showing that engaging with visual puzzles can sharpen your attention span, memory, and even problem-solving abilities over time.
Solving these puzzles gives your brain a quick, effective workout — much like lifting weights strengthens your muscles!
The Hidden Science Behind the Struggle
Wondering why spotting the 42 is so difficult? It's because your brain loves patterns. Once it identifies that the image is mostly 22s and 44s, it stops looking at each number individually and assumes they’re all the same.
This mental shortcut is called "perceptual set" — your mind processes visuals based on expectations, not reality. "Your brain is wired to predict patterns to save time and energy," explains Dr Whittaker. "This usually helps in daily life but makes brain teasers surprisingly tricky!"
That’s why the number "42" manages to slip past your attention so easily.
Tips to Spot the Hidden Number 42
If you’re still struggling, don’t worry! Try these expert tips:
Slow Down: Instead of rushing, scan each row slowly and methodically.
The goal is to reset your brain’s assumptions and observe each tile carefully without making predictions.
The Benefits of Doing Brain Teasers Regularly
Beyond being a fun diversion, brain teasers and optical illusions can actually boost your mental strength. Regular practice can:
Improve memory and concentration
"Think of optical illusions as mental yoga," says Dr. Whittaker. "They stretch and flex different parts of your brain, keeping it young and agile."
Did You Find the Lone 42?
If you spotted the number 42 — congratulations! You’re part of the rare 1 per cent with exceptional visual skills and focus.
If not, don’t be disheartened. Remember, it's the effort and practice that make your brain sharper over time.
Need a hint?
Look towards the centre-right section of the image, near the middle rows — you might just catch that elusive number hiding between familiar patterns!
