Reaction time test online
Wait for green, then tap. Our free reaction time test adds fake-outs, decoy shapes and double taps so it stays fun after the first go. It is a game, not a lab test.
Start here
- Reaction Rush: five rounds per set, your average in milliseconds and a rank from Snail to Lightning.
Other quick reflex games
- Tap Tempo: hear the beat, then keep the tempo in silence.
- Fast Hands: a two-player duel. Tap first when the light changes.
- Beat Tap: tap gems in time with the music.
- Colour Clash: tap the paint, not the word.
Getting a faster time
Keep your thumb hovering above the screen instead of resting on it. Never guess: an early tap counts as a slow round. Phones add a small delay, so use the test to compare yourself with your own earlier scores and with friends.
