The chart features a sea of identical numbers, each reading 4502.
However, there one different number, hiding in plain sight.
And it takes someone with eyes as sharp as a hawk to spot the odd one out - especially if you manage to do it in less than 20 seconds.
Ai Ching Goh, co-founder of Piktochart, said of the brainteaser: "This campaign is a fun reminder of how easy it is to miss small details, especially in data-heavy designs.
"Imagine you're at work and your boss asks you to check over the latest numbers.
"Would you be able to spot the mistake?"
If you're struggling, it's a good idea to take the puzzle column by column.
Scroll down through the rows as you flit your eyes up and down, trying to spot the number that doesn't fit.
If things aren't getting any easier, try splitting the box of numbers into quarters - taking one at a time.
And if your frustration is getting the better of you, you can find the answer below.
