THINK you’re clever? Try this optical illusion.
In the photo below, viewers are asked to spot the zero in amongst endless rows of the number six.
The classic number illusion puzzle has rows and rows of nearly identical digits designed to mess with your eyes – and patience.
But it’s not as easy as it appears – inside the sea of sizes is a sneaky zero.
The colour of the background doesn’t help either – the dark blue makes it trickier to see.
Meanwhile, we tend to view images from the centre outwards, meaning our periphery can be neglected, particularly when focusing on intricate details.
Can you spot it? If that’s a yes, how long did it take you?
Optical illusions like this one are not just quirky brain teasers, they are a legitimate workout for your brain.
Think of them as being Sudoku’s cooler, visual cousin…
They boost focus and attention to detail; finding the odd one out forces your brain to slow down.
They also improve visual memory as your brain starts to learn how to memorise patterns and shapes.
If you still haven’t spotted the zero… keep scanning through the patterns line by line and zoom in on the subtle variations.
Since six and zero are circular cousins, the difference is really subtle.
Still not found it? Count eight lines from the bottom upwards, and then 10 inwards from the right. There it is!
If you enjoy that optical illusion, why not see if you can spot the number 879 in under eight seconds in this one?
There’s also a sea of B’s in this optical illusion, but where is the number eight hiding?
What about testing your eyesight by spotting the word ‘Ball’ in this mind-boggling illusion?
