Are you in the top 20% who can see the hidden number?

Now, this is puzzling.

A TikToker posted an optical illusion that tricks the eye, with a number hidden within a black and white background.

Trouble is, only some can see the number.

TikTok magician @pasillusion shared the illusion with his 6,500 followers, asking them to find the “hidden” number within some black and white horizontal lines.

“What do you see in this image?” he asked.

According to the illusionist, only two out of five people can make out a number — and many of his followers indeed found the task difficult.

“It’s just lines,” one baffled user wrote.

“Maybe try wriggling your phone,” suggested another.

Although viewers weren’t consistent with their answers, many reported seeing a number containing a 7 and the majority reporting spotting a 17 in the lines.

He recommends holding the phone out further away from your face if you can’t see a number.

If that one wasn’t tricky enough, have a go at this illusion, which contains five hidden numbers, with only people sensitive to color perception able to detect all the numbers from the video.
