One Brain is inspired by the Stroop effect, a famous psychological test that measures how well you handle conflicting information. For example, it's harder to name the color of a word when the word itself spells a different color. This game challenges your whole brain as you fight to process the mixed signals and make the right call before time runs out. Game modes: • Colors: Does the word match the color it's written in? • Arrows: Is the arrow actually pointing the way it says it is? • Numbers: Is the math equation true or false? • Words: Which word matches the definition? How high can you score under pressure?

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! To top off your confusion, you will only have a limited time to make your decision. So focus and sharpen your senses, because this game will definitely get you in a rush! Compete against your friends and the rest of the world for the highest score, unlock various achievements and master the Stroop effect. This game isn't only fun, but also a great way to stay sharp while killing time.

Verdict
The clearest difference is ads: Stroopid at none against One Brain's shown. Stroopid also leads on iOS requirement (9.0 vs 15). One Brain's advantage is rating (4.4 vs 4.0) and ratings volume (297 vs 5). On price, in-app purchases, monetization model and device support there is nothing between them.
