People looking to test their knowledge will often attempt a selection of difficult brain teasers to determine the extent of their IQ.
The difficult puzzles have a clever way of testing a person's brain capability as they often tell someone a lot about their personality traits.
A newly surfaced illusion is helping those discover whether they have hungry brains as allegedly only those with the trait can solve the puzzle within the given time limit - which is less than 15 seconds.
The task is simple - you must spot the odd hot dog within the graphic image in just 12 seconds.
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 we'll give you a little hint...
The one hot dog, which is odd in the image, doesn't have a mustard dressing on top as the rest do.
Still struggling? Scroll down below for the answer...
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?
Allegedly only a true genius can spot the bar of soap in this image of rubber ducks within just 21 seconds.
Alternatively, if you've ever wanted to put your love of tea to the test then try and find the sugar cubes within this brain teaser within 46 seconds.
