Reaction time test
Most reaction tests are solitary: click when the colour changes, get a number, close the tab. The blocks.pw version runs the same measurement — milliseconds from stimulus to tap — inside a 30-second duel against a real person, because a number means more when someone's trying to beat it.
How the test works
- Open blocks.pw and start a quick match (or send a challenge link to a friend).
- In each Reflex round, a block appears red. Wait.
- The instant it turns green, tap. Tap early and you forfeit the round — anticipation is cheating, and the game knows.
- Your time in milliseconds shows after every round. Best of 5 decides the duel.
Reading your result
Single rounds are noisy — nerves, blinks and touch latency all add jitter. Judge yourself on the average of at least ten rounds. Once you have it, look it up: the average adult sits near 273 ms, trained gamers near 230 ms, and pros between 160 and 200 ms.
| Who | Typical reaction time |
|---|---|
| Pro esports player | 170 ms |
| F1 driver (start lights) | 200 ms |
| Average gamer | 230 ms |
| Solid amateur — 250 ms | 250 ms |
| Average adult | 273 ms |
| Average at age 60+ | 330 ms |
Then get your verdict on the dedicated pages — for example is 250 ms good?, is 200 ms good?, or find the top 10% threshold.
Why duels beat solo tests
Two reasons. First, pressure: your reaction time under mild stress is your real reaction time — the one you'll have in a game, a car, a sport. Solo tests flatter you. Second, honesty: it's easy to retry a solo test until a lucky 160 ms appears. A best-of-5 against another human averages the luck out.
Make the number move
Reaction time trains well: most people cut 10–15% in a month of short daily sessions. The method — warm-ups, session length, what to measure — is in how to improve your reaction time. Your expected baseline by age is on the age curve.
