Stroop Challenge
Train your brain with the classic Stroop effect — how fast can you name the color?
About Stroop Challenge
Stroop Challenge is a brain-training game based on the Stroop effect — the delay in reaction time when the name of a color is printed in a different color ink. Your goal is simple: identify the color of the text, not the word itself. It sounds easy, but your brain has other ideas.
Choose from three game modes: Timed gives you a fixed 30 seconds to score as many correct answers as possible, Bonus rewards correct answers with extra time, and Endless removes the timer so you can focus on accuracy. The game tracks your high score, best accuracy, longest streak, and score trends over time so you can measure real improvement.
Stroop Challenge also features daily challenges, unlockable achievements, and detailed statistics. With a vibrant dark-themed interface and six color buttons at your fingertips, every session is a fast-paced mental workout you can pick up anywhere.

Frequently Asked Questions
What is the Stroop effect?
The Stroop effect is a psychological phenomenon where your brain takes longer to name the ink color of a word when the word itself spells a different color. For example, the word “RED” printed in blue ink causes a delay because your brain wants to read the word rather than identify the ink color.
