Experience the psychological phenomenon called "Stroop effect": Tap the colors that you read, not the ones you see. Easy enough? Read on.

If, for instance, the word "blue" is written with red ink, your brain will process the ink color much faster than the written word "blue". As a result, you will want to tap red when you actually should tap blue. Go ahead and try for yourself!

Compete against your friends and the rest of the world for the highest score, unlock various achievements and master the Stroop effect.
