Only people with 'hawk-like vision' can pick out lost banknote between the receipts in 30 seconds

An optical illusion that needs to be completed in ‘30 seconds’ has left people struggling to find the solution - if you can solve it then your vision is exceptional

A new brainteaser is putting people’s vision to the test - if you can solve it and find the bank note you’ve got ‘hawk-like’ vision. The puzzle is a form of visual illusion, and it’s safe to say it is a rather challenging one. The image - which features a mixture of different coloured receipts with a bank note hidden sneakily among them - is designed to challenge cognitive function and visual perception.

According to neurological experts, taking the time to do regular mental exercise, such as brainteasers, can provide a range of cognitive benefits, which may help to reduce your risk of developing dementia and other neurodegenerative diseases.

This new brainteaser - which comes with a 30 second time limit - has been shared by Capital on Tap, and has been designed to provide a challenge to puzzle enthusiasts. This kind of brainteaser requires sustained attention, which helps to train your brain to concentrate for longer periods of time. According to researchers, this can also boost focus in other areas of your life as well.

Struggling to find the bank note? It’s not easy, that’s for sure. The best way to tackle these kinds of visual puzzles is to break them down into smaller sections, focusing on one section at a time, slowly working your way through the entire puzzle. This can make finding hidden elements, such as the bank note, a little easier to achieve.

The answer to this puzzle is rather well hidden, with the bank note being slotted underneath two receipts in the bottom of the picture. You can spot the sneaky bank note - which is a lot smaller than the receipts - if you look at the very bottom of the image towards the right hand corner.
