Only those with perfect vision can find the phone hidden in this messy room in 5 seconds

Brain teasers and optical illusions are a fantastic way of improving your cognitive abilities, and training your brain to work on more complicated puzzles over time is great for boosting brain power.

While you might struggle with some puzzles at first, the more you practice the faster you'll get, so don't be discouraged from trying out a few brain teasers and seeing how you get on.

And if you're on the hunt for a new puzzle, why not try out this tricky teaser which challenges you to try and find the phone hidden in the messy living room scene? It seems like it would be easy, but with so many other toys and objects scattered around the picture, it's harder than it looks.

The image was created by furniture company ScS, and shows two adults and three children playing in their living room, which is littered with toys including small cars, teddy bears, and building blocks.

But somewhere in the picture, there's a phone lurking, and it's your task to find it as quickly as you can.

You can take as long as you need to find it, but if you can do it in five seconds or less, then you might just have perfect vision, as that's the quickest time the teaser has been solved so far.

Meanwhile, if you find the phone in less than 15 seconds, you are within the average.

If you're struggling and need a hint, try looking for a different sort of phone. You're not trying to find a mobile phone here, but instead, you should be looking for an old-school rotary phone.

Got it now? If you don't want to see the answer yet, don't scroll any further as we're about to show the solution!

In the mood for more puzzles? Why not try a number-based game like this one, where you have just eight seconds to find the number two in a sea of other digits.

While there are also many similar puzzles that use words instead of numbers, such as this one that challenges you to find the word 'cold' among the 'gold's, or another that hides the word 'bare' in a sea of 'bear's.

For players who prefer image-based challenges, why not try this waterpark-themed brain teaser? In a mind-bending twist, you're searching for the blue rubber ring, nestled somewhere between the aquamarine swimming pools.
