Optical illusion: You're a genius if you can spot the 8 among the Bs in a few seconds

Let’s play a quick little game to give your brain a fun workout—and hey, you might even impress your friends with this one. Take a good look at the image above. At first, it just looks like a neat grid of blue diamonds, each with a white capital letter B inside.

But here’s the twist: hiding somewhere in that sea of Bs is a sneaky little number 8. Spot it without going cross-eyed.This kind of puzzle is all about tricking your brain. The design is repetitive and hypnotic. Once your brain gets used to seeing the same thing over and over, it stops checking each one closely. That’s exactly how the number 8 manages to blend in so well.Now, the letter B and the number 8 do look super similar.

But if you look a little closer, you’ll spot the difference The number 8, though? It’s all curves—more like two perfect little circles stacked on top of each other. That roundness and symmetry is your best clue.Here’s a tip: don’t just stare at the whole grid hoping it’ll jump out at you. Start at the top-left and slowly move across, row by row. You don’t need to read each B—just look at the overall shape. Most of the Bs will start to blur together, but the 8 will feel just a little different.

A little too smooth. A little too balanced. You can even try zooming out or squinting your eyes—it helps change what you notice.

Still can’t spot it? Want a hint?

Head down to the last row from the bottom, then move one diamond in from the right. There it is—the hidden 8.

So, why does this trick work so well? It’s thanks to something called pattern fatigue. Basically, your brain gets lazy when it keeps seeing the same thing over and over. It stops paying attention to the details.

That’s how the 8 slips by. It’s like a tiny visual glitch in your mental matrix.But honestly, that’s what makes puzzles like this so fun. They’re more than just games, they’re like little brain workouts. They sharpen your focus, improve how you recognize patterns, and even boost your memory.

It feels like solving a secret code.Want to get better at these? Try stepping back from the screen, squinting your eyes, or even flipping the image upside down. It helps your brain see things in a different way. And once you’ve found that sneaky 8?In the end, this little visual game is a reminder that the smallest differences can be the hardest to spot—and that even the sharpest minds can be tricked.
