Reaction Time Test: how fast are your reflexes?
Wait for green, then tap. Five rounds, one average.
A simple test with a surprisingly competitive streak. Wait for the box to turn green, then tap or press Space as fast as you can. After five rounds you get your average in milliseconds.
How to play Reaction Time Test
- Tap the box to start.
- Wait while it's pink — tapping early resets the round.
- When it turns green, tap immediately.
- Your average of five rounds is your score.
Tips and strategy
- Rest your finger lightly on the screen or key — no big movement needed.
- Look at the center of the box, not the edges.
- Your device matters: wired mice and high-refresh screens shave milliseconds.
- Take three warm-up rounds before going for a record.
