Another optical manipulation phenomenon is appearing on the internet, leaving a multitude of users lost in thought. One of the most popular optical illusions involves finding the number 76 concealed in a column of ’79’s. Although it sounds simple, such a task has proven much more complicated.
Why This Illusion is So Tricky
Every optical illusion has a way of disturbing the way the brain naturally processes information. In this case, the proximity of the ‘7s’ and ‘9s’ make it so that the difference that the ‘6’ is creating, is often very hard to pick out. When humans scan the puzzle, they tend to over-attach the puzzle and they end up skimming over the oddity.
What adds to the puzzle is this idea of having a time limit. Users are often participating in ‘dares’ where they must find the number 76 in under ’10’ seconds. In the world of ‘dares’, many seizures the number in the time limit are considered to have extraordinarily sharp vision, while the rest of the users tend to take longer and perform the task slower.
Response via Social Media

The challenge resonates with a large audience of puzzle enthusiasts on platforms like Tiktok and Instagram. Some users gratify themselves with the fact that they spotted the hidden number in no time, while others, in a lighthearted manner, say that they attempted the challenge multiple times and ultimately gave up. Such responses help shed light on the reality of how differently people perceive and process visual information, even when observing the same image.
Explaining the Entertainment
Psychologists state that in optical illusions like this one, the visual crowding effect plays a key role. This effect involves target objects becoming more challenging to identify when surrounded by other objects. The endless stream of repeating “79” numbers distracts the viewer to the “76” they block. This exercise serves as a playful challenge of focus and perception and is, in fact, crucial in developing concentration.
A Morning Mental Stretching Exercise
Experts frequently suggest that doing short puzzles serves as a useful means to stimulate the brain. In this context, finding numbers embedded in complex patterns is more than a hobby; it can help sharpen one’s focus, enhance problem solving abilities, and ultimately serve as a “mental warm-up” for the rest of the day. Hence, it is not surprising that these puzzles have attained the status of being a relative favorite on the Internet.
Optical illusion Answer

With millions already invested in this puzzle illusion, “Find 76 among 79” has certainly reached the level of social media virality, much like its puzzling brethren.
