Optical Illusions

What s real? What s not? Reality is strange and seeing isn t believing. When you look at an optical illusion, your brain tries to fool your eyes and what you expect to find on the page isn t what s there.

Apart from being both endlessly fascinating and awe-inspiring visually, these illusions also force viewers to go outside their comfort zones, challenge the nature of perception, and think creatively. Their minds have to work overtime to become more flexible. That s what makes these 240 puzzles, ranging from simple scintillation effects to impossible staircases and concealed creatures, so absolutely addictive.
