Reaction Time Test: How Fast Are Your Reflexes?

Average human visual reaction time is about 250 milliseconds. Elite gamers and sprinters often react in under 200 ms. Touchscreens and monitors add a little delay, so compare scores on the same device.

Wait for the box to turn green, then tap or click as fast as you can. Tapping too early counts as a miss. Any round under 300 ms counts as a pass.
