Actually, it's a breeze. To my shame I must confess that I have it I bought myself for a successful game night. Especially with more than one person makes this game a lot of fun. The most pressing needs with the color keys are played. It also trains straight to the reactions (speed, color sequence ..). Great game, which also contributes through its graphics for fun. Is also suitable for smaller children. So it is great for an intergenerational game night.
