Only 10% Of People Can Find All 9 Faces In This Picture. Can You?

Pattern recognition puts humans at the top of the food chain. Having the ability to pick out shapes and fill in gaps is one of the hallmarks of our big brains. 

However, that deeply ingrained tendency to fill in those information gaps can play havoc on our brains sometimes. We see things that aren't really there: optical illusions.

They can be frustrating, but optical illusions can also make for great puzzles. You have to overcome some of your brain's most powerful instincts to make sense of what you're seeing and sort out the information. 

Here are a few brain-teasing optical illusion puzzles to challenge your eyes!
