Only those with sharp vision can find a duck hiding in optical illusion

Have you got strong eyesight and a good attention to detail?

Prove it by trying this baffling brainteaser that's been bamboozling people on Reddit. In the r/FindTheSniper forum, players are being asked to spot the hidden duck.

The image in question shows a sea of pebbles and stones. But lurking within the rocks is a child's lost toy duck – so can you spot it?

It's a lot harder than it sounds – as the duck in question is transparent! The mind-melting snap left people completely stumped, with some complaining it was too hard.

One user asked: "There's witchcraft afoot in how well that was hidden!" Others felt more confident in tackling the challenge though.

To make things easier, Redditors split the image into sections and carefully combed through them. Casting your eyes from left and right in a methodical way can help you to locate the offending rock.

If you need a hint, it's on the left-hand side of the snap. And if you need more help, the answer is below...

Sharing the answer finally, one person responded: "I found it. It's a tiny translucent glass duck directly in the middle of the left side of the image. Find the cracked twig that sort of looks like a clothespin and follow it down in a straight line slowly and you'll see it. You're welcome, hope it helped."

Brainteasers can be beneficial for your mental fitness in several ways. They often require critical thinking, problem-solving, and analytical skills, so have the potential improve cognitive abilities when done regularly.

Research shows that memory puzzles can improve how much information we're able to retain and recall too. They're also said to boost concentration, bust stress and be a good way to encourage learning.
