Only people with high IQ can spot the odd letter out in less than 13 seconds

Everyone loves a good brain teaser. They can be a great way of helping you focus as well as challenging your cognitive ability, but they can also be a headache sometimes.

A tricky brain teaser was recently shared by JagranJosh that challenges people to attempt to identify a hidden letter among the X's and K's in a row.

Sounds easy right? Well, maybe not so much as there is a time limit, and only people who have a high IQ have been found to be able to spot the hidden letter within 13 seconds.

In the brain teaser, you can see five rows of X's and K's. You will need to scan through all the rows and columns within the short space of time to find the hidden letter.

Could you find the hidden letter in time? If not you can check out the answer below.

Here is the answer (Bright Side)

Have you found the odd letter and now you fancy another optical illusion? Well, people have been struggling to find the horse rider's face hidden in 15 seconds.

This difficult one can be tricky since you can only find the man if you rotate the image.

Another one doing the rounds on social media is one for people who consider themselves above average on the intelligence side of things, in fact, it's for people who reckon they possess "extraordinary intelligence".

This image features a multitude of brightly coloured toy animals. Within the picture, there are lions, hippos, birds, elephants, deer and monkeys all of which are different colours such as yellow, pink, purple and orange.

Alongside all of these animals is a single giraffe (we can’t tell you what colour!) hidden in plain sight. While a lot of people may be unable to locate the giraffe, those with high IQ have been shown to be able to within 11 seconds.
