The five-second time limit might seem short, but it’s sufficient if you scan the image carefully. Just make sure not to miss any number, and you’ll be able to find it easily.
The solution to the puzzle is that the number different from the rest, hidden in the image, is 280. The rearrangement of digits makes it tricky to distinguish from the other numbers. However, by scanning the image methodically and not skipping any numbers, one can easily identify it.
If you could find the number effortlessly, you likely have a sharp eye for details and a sharp mind for scanning images correctly. If you couldn’t, you may need to practice more to reach a level where such puzzles won’t seem too difficult.
There are numerous optical illusions available online for practice. Some can reveal personality traits, while others can help you improve your speed in finding accurate solutions to puzzles.
