How to play Reaction Time

Wait for the signal and react consistently.

Test your response speed alone, race up to eight friends, or play a team relay. Each trial starts with an unpredictable wait followed by a green signal. Your browser measures from the visible cue to your input, so network travel is excluded from the result.

01 / The essentials

Reaction Time rules

  • Tap Start trial, then wait. React only when the pad turns green and says GO.
  • Complete 3, 5, or 10 trials. Lowest average wins; everyone finishes before results are compared.
  • Early presses, interrupted or missed trials, and responses below 80 ms count as 2,000 ms. These games are casual and unrated.

02 / Build the habit

Reaction Time strategy

Stay relaxed

Keep your finger or mouse ready without pressing. Wait for the actual signal instead of guessing its rhythm.

Use a consistent setup

A screen and input device can affect the result. Use the same setup when comparing practice sessions.

Review every trial

Look at the individual times and penalties. A steady set of responses beats one lucky press followed by several early starts.

03 / Worked example

Average the whole run

Three responses of 220 ms, 240 ms, and 260 ms produce a 240 ms average. A false start would count as 2,000 ms instead of disappearing from the run.

04 / Put it into practice

Learn with your table

  1. Start with five solo trials.
  2. Review the bars and your best response, then repeat using the same input device.
  3. Invite a friend or choose Reaction Time in a team relay. Relays add trial times across all runners, excluding random waits and handoffs.

A common mistake

Anticipating the signal can produce an early press. Holding Space does not repeatedly answer trials; each response must be a fresh input.

Does my ping count?

No. The client starts its monotonic timer when it renders the green cue and stops it on your input event. Delivery time is excluded. Client timing is suitable for casual play; it is not a cheat-proof competitive measurement.
