At first glance, you might only spot a few, but if you take a moment to focus, you’ll begin to notice more dolphins popping up. It’s incredible how easily our brains can overlook these hidden details at first sight! So, how and why do they trick our brains? Optical illusions work by exploiting the brain’s shortcuts. When we look at something, our brain interprets the visual information it receives, but it doesn’t process every detail.

Instead, it makes assumptions to simplify things, which is how optical illusions trick us into seeing things that aren’t there. While optical illusions hide images within visuals, brain teasers challenge our logic and reasoning skills. Both are excellent ways to sharpen our minds and provide fun challenges.
