Users on TikTok were challenged to test their vision and attentiveness by looking at a picture with several dozen blue trucks. At first glance, they all appear to be identical, however, your task is to find the one that differs from the others by just one small detail. And you need to do it as quickly as possible.

The girl in the video said, ‘Only one person out of twenty can find the truck that differs from the others in less than 40 seconds,’ and then she started the countdown.
