Reaction Duel

A reaction time test, made into a duel

Reaction tests are fun on your own for about a minute. They get serious the moment someone else has a number to beat. In Reaction Duel you send the link, and the moment your friend joins, you both play the exact same five rounds: the same waits in the same order. Nobody can practise in advance, so the only difference is you.

Every tap shows up live for anyone watching, and when both of you are done the faster average wins. Jump the gun and the round counts as a full second, so nerves matter as much as speed.

How to play Reaction Duel

Send the link first

The rounds unlock once your friend has joined, so you both start on equal terms. You can play at the same time or one after the other.

Tap to start

Once both of you are in, tap the button. It turns red. Keep your finger ready and wait.

Wait for green

After a random pause the pad turns green. Tap it as fast as you can. Tapping early is a foul worth 1,000 ms.

Five rounds

Your five times are averaged. Lower is better.

What is a good reaction time?

Most people react to a visual signal in about 200 to 280 milliseconds. Under 200 ms is excellent, and a consistent average under 180 ms is exceptional. Times below 100 ms are not possible as a genuine reaction to a signal, so Reaction Duel treats them as a guess.

Your result depends on more than reflexes: the screen, the browser and the device all add a few milliseconds. When you duel on BeatMe, both players get the same rounds, so it is as fair as a remote test can be. For the fairest duel, use similar devices.

How to get faster

  • Stay relaxed. Tension slows you down. Rest your finger lightly on the screen, just above the pad.
  • Look at the centre. Keep your eyes on the pad, not on your finger.
  • Do not guess. The waits are random. A foul costs far more than a slightly slow tap.
  • Warm up. Your first round is usually your slowest. Rematches are free.

Reaction Duel FAQ

Is this a real reaction time test?

Yes. It measures the time from the moment the pad turns green on your screen until your tap registers. It is the same principle as classic online reaction tests, played as a duel.

Do both players get the same rounds?

Yes. Both players get exactly the same five waits in the same order, so nobody gets an easier round.

Can I play first and send my score?

No, on purpose. The rounds unlock only after your friend has joined, so nobody can post a practised or scripted score and then send the link.

What happens if I tap too early?

That round is a foul and counts as 1,000 ms. You still play all five rounds.

Can I cheat by tapping in advance?

The waits are random and kept on the server until each round starts, and the server checks that every time fits the time that really passed. Times faster than 100 ms count as a foul.

Does my phone matter?

A little. Screens and browsers add a few milliseconds of delay. For the fairest duel, play on similar devices.
