There have been many studies that showed how solving riddles and puzzles can help strengthen our brain and its activity. But, besides that, people just love burying their heads into work to try and find the solution to a visual problem presented to them.

Maybe it’s because they want to feel smart or maybe because they love the challenge. Or maybe they want to get their inner detective abilities unleashed. Sometimes we look at an image and something immediately catches our attention because it is not where it should be. Other times we feel that something is wrong,

but we don’t understand exactly what it is and so we have to look more closely. Then we notice details that we haven’t seen before and find more and more inconsistencies. Okay, that doesn’t usually happen in everyday life, but it does happen in our selection of images with strange errors that are difficult to detect!
