An optical illusion has been making rounds on the internet and leaving people baffled.

If you like challenges that push you to the limits, you’re going to love what we have in store for you. Below, you can see our first picture puzzle – one that hasn’t gotten any easier despite being around for quite some time!

In the picture, you’ll quickly see a series of interconnecting lines in a spiral black pattern. Somewhere in there, there’s also a long number that you should identify in less than 30 seconds to pass the test.

What number have you found? You probably saw the numbers 5, 2, and 8 in the middle of the picture quite quickly. But to pass this test, you have to identify the COMPLETE number.

Before you jump to any conclusions, take another close look and put in your best effort.

What’s your final answer? If you answered ‘3452839’, then you win! Congratulations.

And if you’ve seen anything less than seven digits, we’re afraid to tell you this challenge might have been too much for you.

The puzzle quickly went viral after it was first shared on social media, whereas many viewers were left baffled by the hidden numbers on the edges of the picture.

“I can only see 528. Does that mean anything about my eyesight?” someone pondered.

“I can see 45283, since looking at the other replies I’ve others are seeing two other numbers. I can see there are numbers there but can’t make them up,” another admitted.

A third said: “45 283… and what’s the catch? Should I book an appointment with my GP?”
