TIME to put your brain to the test with this tricky brainteaser.

If you are able to spot the number 8 quickly in the image below, you might have a high IQ – or you could be well on your way to boosting it.

This brainteaser, featured by The Times of India, presents a grid of blue diamonds, each containing a white capital letter ‘B’.

But hidden among them is a sneaky number 8, cleverly camouflaged within the pattern.

The repetitive design of this puzzle can lead your brain to scan less attentively, making the number 8 blend in—a phenomenon referred to as pattern fatigue.

It doesn’t help that the letter ‘B’ and the number 8 already look strikingly similar.

To improve your chances, try not stare at the whole grid hoping the number will pop out.

Instead, scan the image row by row, moving slowly across each line.

You can also try zooming out, squinting or even flipping the image – all ways to help your brain see the grid from a new perspective.

If you’re struggling to spot it, here’s a hint: it’s hidden in the last row.
