A new brain teaser asks people to spot the mistake in just seconds.
A user on Playbuzz created the challenge, telling people they should spot what’s wrong in less than five seconds.
The puzzle looks simple, with nine numbers--each a different color.
The creator said: “It’s harder than it looks.”
The brain teaser is just the latest to sweep the Internet--another that cropped up recently from British company Greggs.
The bakers posted a picture of food, saying: “Can you spot the Cheese & Onion Bake in this picture of Steak Bakes?”
For the top pic, here is a hint: look at the “the” in the sentence.
