How fast are your reflexes? Tap when the screen turns green. Five rounds — no sign-up.
A reaction time test measures how quickly you respond to a visual signal — the average human reaction time is around 250–300 ms. Braindle turns it into a daily challenge: every day at midnight UTC, everyone worldwide gets the same five 2-minute brain games (reflex, memory, mental math, judgment, and aim), then compares scores on a global leaderboard.
The web test above is just the reflex round. The free Braindle app adds four more modes, a shareable result card, streaks, and friend duels. One puzzle, the whole world, every day.
