There's nothing better than getting your brain going with optical illusion quizzes, and we have the best one for you right here!

Optical Illusions can use a mixture of patterns and colors to create images that can our brains struggle to make out unless pointed out. The information is then processed by our eyes, creating a perception that does not match the true image.

They occur because our brain is trying to interpret what we see and make sense of the world around us... they basically trick our brains into seeing things that aren't real, or things that don't look real.

Not only do these quizzes increase mental focus and attentiveness throughout the day, but they also help you stay more alert in day-to-day life.

The latest optical illusion to hit the internet is deceivingly simple until you look a little closer. All you have to do is count and see if you can find all the 7s in the picture below. It's perfect to give your mind a break from whatever task you have going on, and it also gives your brain a bit of a workout, which is never a bad thing.

Now it might sound simple, but believe it or not, lots of people have struggled to get the right answer, as there might be more than first meets the eye. So don't let it catch you out.

If you can do it in less than sixty seconds, be proud because that means you have incredibly sharp vision. And don't worry if you get stuck, because you can always scroll down to get the answers if you can't figure it out.

Now let's take a look at the puzzle...

Answer below...

If you look at the picture above, you will notice that it is made out of a collection of the letter Z and the number 7. There are far more of the letter Z than there are of the number 7 and in total, they take up the shape of a larger number 7.

So altogether there are 6, 7s...

Many people struggled to find the correct answer...

With one writing: "Well you could consider them all 7's, but in the interest of the image, how about 6 with the large 7. So 7 all up."

"7, if the giant 7 formed by all the other 7s and Zs counts, too," wrote a second commenter.

A third wrote: "I'd have to count the big one and all the z looking things upside down and right side up. Ain't nobody got time for that. Lol."

"Don't know if anyone else has come up with this but they could all be 7's underlined!" Commented a fourth.

Did you get it right?
