Fake Illusions is a collection of optical illusions—but some of them are not playing fair! Where some lines only look diagonal, one line actually is, and circles look like they differ in size, but secretly, one of them is bigger or smaller, camouflaged by the illusion. It's your job to point them out! But beware—the fakers will do everything to stay unnoticed... It's the ultimate test of your focus!

Featuring ten different versions of famous illusions like the Hermann Grid or Müller-Lyer arrows, each with a number of variants and distractions, for a total of 50 levels! If that's not enough, try the relaxing Zen mode or the hectic Shuffle mode. You can play it together too: as long as everyone can see your screen, you can use the number each illusion is tagged with to discuss and accuse fakers. You can even export your favorite puzzles as a GIF after solving!

Fake Illusions was made by solo developer Auroriax (best known for Mobility! The accessible precision platformer). Want to try the game? The @FakeIllusionBot tweets a puzzle from the game every day! (There's also a presskit.)
