For anyone looking for a challenge to round off their week, a good brainteaser will help you to do just that.
They're often a great way to test out your observational skills, particularly when they require sharp eyesight and concentration to focus on an image and spot an anomaly.
With that in mind, why not try out this brainteaser that challenges 'hungry' brains to try and spot the odd hot dog amongst a selection of seemingly identical ones?
If you can find the odd one out within 12 seconds then your observational skills are on point and you have a 'hungry' brain type, the Mirror reports.
Only those with that personality trait can solve the puzzle within the timeframe - so have a look at the graphic below and see how well you do.
If you're a fan of food - or you consider yourself to have razor-sharp eyes - then give a try looking out for the anomaly in this image.
Throughout the hundred hot dogs that are pictured before you, there is one that is visibly different from the rest.
If you're struggling, then here's a hint.
The one hot dog, which is odd in the image, doesn't have a mustard dressing on top as the rest do.
If you weren't able to spot the hot dog, then we've circled it in red for you.
It's located on the bottom right-hand side of the screen and shows a naked sausage - without the mustard.
If you're wanting to test yourself further or you're a fan of optical illusions, then why not try giving a few of these a try?
This difficult brainteaser requires you to find the cat without the tail as fast as you can, but it's not an easy task to do - so give it a go if you're up to the challenge.
And this one contains a hidden hanger that must be spotted amongst the other items of clothing, stressing the importance of keeping your wardrobe space nice and neat.
