The dot test is the latest brainteaser to take the internet by storm.
Created by Playbuzz, the puzzle has nine stages with each stage having a different colour theme.
Participants are given a choice of four letters and they have to spot the letter contained within the dots.
THe challenge starts off easy enough, but gradually get harder as it becomes increasingly challenging to spot the letters that blend almost seamlessly with their backgrounds.
If you do manage to find all the letters, the congratulatory message from Playbuzz reads, "That was AMAZING!
"Not only did you pass, the fact that you were able to see all the letters across the spectrum proves that you have incredible vision and a particularly trained eye.
"This means that you can see better than the average person, and live in a more colorful, vivid world."
