Only people with a high IQ can spot the number '6' in this brainteaser in 10 seconds

A new brain teaser claims that only highly intelligent people can spot the number six in a sea of nines.

The goal is to find the designated number within 10 seconds or less, making it important to carefully look through the image.

Spotting the number requires quick thinking, and if you can find the letter in the allotted timeframe, your level of intelligence is higher than people who take longer.

These types of brainteasers can tell you a lot about how you think and view the world and help you develop problem-solving and logical reasoning skills. 

The picture shows columns of 78 numbers in total, with just one six hidden somewhere among the nines.

Finding it may not be as simple as you think, requiring quick problem-solving skills to look at the brain teaser from all angles.

The key could be breaking the image down by sections and move from left to right or top to bottom to locate the six in record time.

If you look at the fifth column in the bottom row, the six is easily discernable from the endless number nines.

These puzzles are meant to challenge your brain and are a good way to stimulate your mind.

This brain teaser is like many others that are used to test your mathematical or lateral thinking skills, while others are used to test your observational or problem-solving skills.

Solving a brain teaser can reinforce the connections between brain cells to improve a person's short term memory and regulates mood and concentration.

The psychology is rooted in our pursuit of a challenge, reward and mental stimulation - so look at the colorful image and set your timer as you search for the bucket hat.

'Regularly engaging in these puzzles can improve your analytical thinking, making you more adept at finding creative solutions to real-life problems,' according to Erlanger Health.

One of the big reasons people love brain teasers is because of the challenge and reward they present and the more difficult the puzzle is, the greater sense of accomplishment a person has. 

As people age, memory can start to deteriorate but brain teasers that force you to recall sequences, patterns or details have been shown to enhance memory retention, Erlanger Health reported.

Studies have shown that brain teasers do play an important role in helping memory and attention span, prevent cognitive decline and increase a person's mental agility or ability to process information quickly. 

A 2021 study revealed that the 'logic stress and limit stress generated during playing brain teaser games are positive stress, with a desirable effect on the players' attention.'

'These two types of stress improve cognitive abilities such as attention, concentration and problem-solving by activating the brain's frontal lobe,' the study continued to explain.

And while the letter puzzle might have proved tricky for some, not all brain teasers are the same, rest assured that it may not be that you have a low IQ, it could simply indicate what type of intelligence you possess.
