It's for fun
SpeedLab is a collection of small speed and reflex tests provided for entertainment. Play as much as you like, on whatever device you like.
Your score isn't a diagnosis
A result here is a bit of fun and a way to compete with yourself. It is not a medical, diagnostic, psychological, or professional assessment of your reflexes, health, or ability. If you have a real concern about your reaction time or coordination, talk to a qualified professional, not a website with a cartoon lightning bolt.
