Social media is rife with various puzzles that sometimes challenge our eyes and sometimes our minds. One such number jumble puzzle has been brought forth, requiring participants to find a single number that stands
out from the rest. At first glance, it appears simple, but the hidden mistake is not easy to spot.
In this puzzle, the number 4502 is repeated hundreds of times, with one incorrect number concealed within. To detect it in less than 20 seconds demands sharp eyesight. This brainteaser is designed to test visual perception and sharpen overall mental acuity.
Created by PiktoChart, it underscores the skill of identifying minute errors in data. Ai Ching Goh, co-founder of PiktoChart, launched this brainteaser in 2023.
He remarked, “This campaign is a fun reminder of how easily small mistakes can be missed in data-rich designs. Imagine you are in the office and your boss asks you to check a new number. Will you be able to spot the mistake?”
This puzzle serves as more than mere entertainment; it is an excellent gauge of one’s concentration and logical ability. The numbers predominantly appear as 4502, with one differing number. Finding it under the time constraint of 20 seconds is challenging. If difficulty arises, it is suggested to inspect column-by-column.
Scrutinise the image carefully, scanning up and down each line. If this method proves ineffective, divide the numbers into four sections and search each part. This approach may uncover the erroneous number, albeit exceeding the 20-second limit. With practice, future puzzles can be solved within the designated timeframe.
Even if frustration sets in, there is no need for discouragement. This brainteaser is crafted to sharpen cognitive abilities. Brainteasers function as exercises for the brain, improving problem-solving techniques and mental agility. They engage various brain functions, including memory, logic, and spatial reasoning. The most significant advantage is enhanced neuroplasticity, the brain’s capacity to form and adapt new neural connections.
For those still struggling to identify the correct number, the solution is revealed in the illustration below.

The misplaced number, highlighted in bold, is located at number 11 in D block. Activities such as brainteasers, puzzles, and riddles bolster analytical and logical skills. Piktochart’s number jumble puzzle not only entertains but also demonstrates the critical importance of accuracy in data verification within the workplace. A small error, such as a misprinted number, can lead to substantial losses.
This puzzle offers a delightful challenge for those wishing to test the sharpness of their eyes and minds. Successfully solving it within 20 seconds is indicative of exceptionally keen eyesight. Conversely, if one fails, there is no cause for concern. Regular engagement with such puzzles will soon enhance one’s ability to detect discrepancies with ease.
