If you've been having a bit too much fun this weekend and are in need of something to challenge you, why not try out a difficult brainteaser?
They're great for putting your observational skills to the test, and even more fun if you make it a competition with your friends and family to see who can solve it the quickest.
There are plenty different kinds of brainteasers out there, but arguably the most challenging ones are those that require you to crack it in a certain amount of time - usually a short one.
With that in mind, here's a brain teaser that has left people scratching their heads in confusion, as it's particularly difficult to solve. The Mirror reports all you have to do is find the number hidden among the polka dots, which sounds simple enough.
When you first look at the image, it appears to only feature an array of yellow polka dots against a background of a slightly lighter yellow shade.
But not everything is as it seems because there's actually a number hidden in the dots - and according to Jagran Josh, you'll need "X-ray vision" if you want to spot it.
Can you see it? Try and find it within nine seconds or less, and you could be on track to call yourself a genius.
If you're struggling, here's a clue: you're looking for a three-digit number, and you'll want to think a little outside the box for this one.
Got it now? We're about to give you the answer, so if you're still working on it, don't scroll any further.
The number you were looking for was 725, and it was hidden in plain sight in the middle of the picture.
If you want to keep on challenging yourself, why not try this one that requires you to find the hidden number 725 amongst the 775s?
Or, give this one a go that requires a 'high IQ' to decipher the hidden word in 10 seconds or less.
