Viral Optical Illusion Hides a Mystery Number — Can You See It?
A new optical illusion created by online casino Jackpotjoy is puzzling the internet. At first glance, it looks like a dizzying blue spiral pattern — but hidden within is a secret number.
“We’re celebrating a big birthday, and the number is right in the image,” said Jackpotjoy’s Alex Fagelson.
According to the site, 9 out of 10 people can spot the number if they stare long enough. Still stuck? Try zooming out — a trick that often helps reveal the hidden figure.
Once adjusted, a subtle white “20” appears, marking the casino’s 20th anniversary.
This is the latest in a series of visual brain teasers that have left viewers scratching their heads — or their eyes.
