Why Optical Illusions Are So Engaging

This creates moments of surprise when something unexpected appears. These puzzles activate visual decoding, challenge your mind perception, and push your brain to rethink familiar layouts. When numbers, shapes, or lines blend together, the brain works extra hard to separate them, making the experience both enjoyable and mentally stimulating.
