OPTICAL illusion enthusiasts won't be able to grasp a simple trick that changes numbers completely.

TikTok Taylor Nikolai shared the amazing illusion with his 1.9 million followers.

He said, "This is going blow your mind. I don't understand how it works."

The image shows a normal 03 and 20.

Flip your screen over, and the 02 becomes 20.

"How is your brain able to do that?" The bewildered TikToker was puzzled.

Both images are identical, but one image is flipped.

It is the dotted-pixel format of the text that creates the different numbers.

It can be seen in both ways, depending on how you view it.
