Optical Illusion Test: Only 1 Can Spot The Hidden Number 87 In This Tricky Puzzle
Optical illusions are more than just fun brain teasers — they’re a fascinating glimpse into how our minds process visual information. The latest viral visual challenge is a grid packed with visually similar numbers and symbols designed to trick your eyes and test your cognitive focus. The mission? Spot the number 87 hidden among all the almost identical-looking combinations.
At first glance, the grid appears to repeat patterns like “37,” “73,” and mirrored symbols. But nestled among them is the outlier — the elusive “87.” Most people scroll past without a second look, but if you slow down and concentrate, you might just be among the rare 1% who can find it instantly.
Why Are Optical Illusions So Challenging?
According to Dr Gustav Kuhn, a cognitive psychologist at Goldsmiths, University of London, who specialises in illusions, these puzzles work by exploiting how the brain interprets visual cues. “Our brains are wired to look for patterns and fill in missing information automatically. That helps in daily life but can trip us up when faced with illusions,” he explains.
In the case of this number puzzle, the brain groups together similar shapes and assumes repetition, making it harder to notice the irregularity unless you focus on each individual block.
Can You Spot 87? Here’s A Hint
If you're struggling, don’t worry — you're not alone. Here’s a gentle nudge: Focus your attention on the fifth row from the top and scan from right to left. There you’ll see it — a bold 87 tucked between similar shapes that act as decoys.
Once you spot it, it seems so obvious. But until then, your brain is working overtime to filter out distractions and find the unique element.
What This Puzzle Says About Your Brain
If you were able to spot “87” quickly, congratulations — you may have above-average visual acuity and excellent pattern recognition skills. These types of puzzles are often used in cognitive training to improve focus, memory, and even decision-making.
“These challenges can be a form of mental exercise,” says neuroscientist Dr. Susana Martinez-Conde from SUNY Downstate Health Sciences University. “They encourage you to pay closer attention to visual detail and improve your spatial awareness.”
Why People Love Optical Illusions
The internet is flooded with illusion-based content, and there’s a reason these visual challenges keep going viral. They’re short, fun, and give you a sense of achievement. Plus, they offer a refreshing break from screen fatigue while stimulating your brain.
So, how long did it take you to find the hidden “87”? If you managed it in under 10 seconds, you might just be part of the top 1%.
