Color Key is a colorful and exciting brain-training game designed for all ages. Whether you're a child, student, parent, or adult looking to stay sharp, this game offers fast-paced fun while helping you improve your focus, reaction time, and decision-making skills.

With simple mechanics and vibrant visuals, Color Key keeps your mind active and engaged. A cube drops from the top with a background color and a letter (R, G, or B). Your goal is to tap the correct color label at the bottom that matches the background—not the letter! It starts easy, but as your score increases, the pace picks up, testing your reflexes and attention like never before.
