The internet is full of visual puzzles and brain teasers, and one of the latest challenges to catch everyone’s attention is the “Eye Test” where participants are asked to spot the number of times the letter “m” appears in a grid filled with “n”s.

At first glance, the grid looks simple enough—rows upon rows of lowercase “n”s—but hidden among them are a few cleverly placed “m”s that can easily go unnoticed. This test is designed to challenge your attention to detail, visual perception, and patience.

Why Are These Tests So Popular?
Puzzles like these tap into our innate desire to solve problems and test our abilities. They also serve as a fun way to break up the monotony of the day while giving our brains a bit of a workout. Plus, there’s a certain satisfaction that comes from finding the answer, especially when it seems elusive.
