About One Brain
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?
