Optical illusion: Can you spot 9 in this image?

If you’re into visual puzzles and love testing your brainpower, here’s one that’ll definitely make you do a double take. The image above is a classic optical illusion challenge—at first glance, it looks like a neat grid of identical symbols, like a field of orange "Y"-shaped hooks or boomerangs.

But look closer. Somewhere in this sea of symbols hides the number 9.Yup, there’s a sneaky number camouflaged in the crowd, and spotting it is way trickier than it sounds. Optical illusions like this aren’t just a fun way to pass the time—they’re also a cool test of visual perception, attention to detail, and even brain agility.

Where is the number 9?

If your eyes are starting to cross—don’t worry, you’re not alone! But here's the spoiler (scroll only if you're stuck): The number 9 is sitting proudly in the ninth row from the top and second column from the right.It stands out once you find it, but until then, your brain gets totally thrown off by the repetitive pattern surrounding it. That’s exactly why these illusions are so effective—they use pattern recognition and repetition to confuse your cognitive filtering system. Your mind gets so used to seeing one shape that it starts to overlook anything that doesn’t match the pattern. Tricky, huh?

Why is this optical illusion so fascinating?

This illusion works because of something known as “visual crowding.” When similar objects are packed tightly together, our brains naturally lump them into groups. This makes it harder to pick out individual differences, like a rogue number 9 among a hundred lookalikes. It’s basically our brain taking a shortcut—which, in this case, backfires!And then there’s the "expectation trap.”

Once you start believing that all the shapes are the same, your brain stops actively scanning for differences. That’s why it might take a few tries (or a hint) to find that odd one out.
