Sure, I can’t devote as much time to it as her, but after just a few minutes of sitting down with a tricky mind teaser, I feel refreshed and more energized.

It might just be a placebo effect, who knows. But as long as it makes you feel good, then why not?

A type of challenge that I really like is trying to spot something that stands out in a picture. It can be everything from finding a certain letter to spotting which number is missing.

This morning, I came across a challenge that really tests you brain-eye coordination. I thought this one would be really easy – but looks can be deceiving!

Time limit: 10 seconds

The concept is very simple. Your mission is to look at this picture with dozens of cars. There’s a bus hiding somewhere among them – and it’s up to you to find it.

The thing is, you only have 10 seconds to do it – and not a second more! If you take your time, it gets too easy – and according to YouTube channel BrightSide, most people can’t do it within the time limit.

Did you manage within 10 seconds? If not, the solution is below!

Don’t be shy now, press the SHARE button if you found the bus, or if you simply want to challenge your friends!
