There are exactly 286 frowning faces in the image, but only one impostor.

You might be eagle-eyed if you spot the odd one out between the frown lines within 30 seconds.

So set your timer and start searching the crowd, because the small change is almost impossible to pinpoint.

Whether you go row by row or randomly look around the illusion, you’ll probably start to doubt your eyesight.

You might even start to wonder if there’s another emoji among the bunch at all.

We can confirm that one of the faces, despite looking extremely similar to its counterparts, is a completely different emoji.

If you’re an Android or Microsoft user, you may have a slight advantage.

The software for the tech empires contains these two almost identical frowning faces.

Only those with the eyes of a hawk can see the slight difference in facial features.

If you need a hint, we recommend focusing on the forehead of each face.

One of the emojis gives a different meaning to the question ‘Why that long face?’

The eyes and mouth are both located slightly lower on the face than the rest.

This means the emoji has a larger forehead, making it easier to see the difference from a distance.

The mouth is also slightly smaller than the one surrounding it.

We recommend that you look at the image as a whole and try to spot the features that don’t exactly line up with the others.

If you’re still struggling, we can reveal that the strange emoji can be found six rows down on the right side of the image.

The slightly different face, six rows from the edge of the photo, is barely distinguishable from the other frowns.

If you want to test yourself even further, try to find the spelling mistake in this list of Kim Kardashians.

The word bank has “Kim Kardashian” written dozens of times in pink and purple.

Despite being a household name, the reality star’s name is misspelled once.

Whether you choose to stare or skim, it may take eagle eyes to spot the mistake.

If you’re lucky, you might notice the typo, but if not, we can give you a helpful hint.

Focus your attention on the second Kims column, especially the bottom half.

If you’re still struggling to spot the odd one out, we can reveal that Kim Kardashian’s four from the bottom is the incorrect spelling.

And if you want to try even more optical illusions, we have plenty to offer.
