Where your successful clicks sit
This curve uses only the median of your successful clicks. Streak length and an early click are separate game outcomes and are not converted into a human percentile.

This survival result uses the median of the successful clicks completed before the run ended. The research cards describe simple visual timing, but streak length also rewards restraint and attention, so the streak itself is not converted into a human percentile. See the percentile and age-group research tables.
Reference notes: Game references: human comparison cards use published laboratory and web samples; animal examples come from tactile prey handling and automatic escape research. They add memorable context only and do not rank the biological systems on one scale. Web sample study · Human study · Mole review · Fly study
The streak measures valid signals in this run. It is a game score, not a population ranking or medical result.

How this reaction time game works
The normal reaction time test measures a fixed five-round session. This game changes the objective: keep a clean streak alive for as long as possible. Each successful signal adds one point. Clicking while the panel is still red ends the run immediately, so anticipation and restraint matter alongside raw speed.
Wait
Every signal uses a random delay so memorizing a rhythm does not help.
React
Click only after the panel turns green. Your time is measured with the browser Performance API.
Survive
Continue for another point—or click early and lock in the run.
What the score means
Your streak is the number of valid reactions before the first false start. Median and best time describe only the successful rounds in that run. A longer streak does not prove faster neurological processing: strategy, attention, display timing, input-device latency, and browser scheduling all affect the result.
The local record and up to 20 recent runs are stored only in this browser. They leave this device only if you deliberately use a sharing feature. You can clear the run history from the result card; clearing site storage also removes the local record.
Reaction time game vs reaction time test
The five-round reaction time test and this reaction time game use the same timer but answer different questions. The test gives you a fixed sample—five valid attempts summarized as a median—so you can compare sessions on the same setup. The game removes the finish line: there is no set number of rounds, and the challenge is to keep a clean streak alive while resisting the urge to click early.
That anticipation lock is the whole point. In the test, an early click simply retries one round. In the game, an early click ends the entire run, so restraint and timing matter as much as raw speed. Play the game when you want an open-ended, pressure-building challenge; use the test when you want a repeatable number to track over time.
How to build a longer streak
Resist the rhythm
The delay is random on purpose. If you start tapping to a beat you think you hear, the anticipation lock will end your run. Wait for the actual colour change every single time.
Watch the median, not just the streak
A long streak with a creeping median usually means you are getting tense and slow. A shorter streak with a tight, fast median is often the better session to learn from.
Keep the setup fixed
Display refresh, input device, browser, and fatigue all move your times. To compare runs fairly, play on the same setup and note the conditions—this is a game score, not a medical or population ranking.
Measurement notes
Keep training
Try a different protocol next
The survival game rewards restraint and consistency. When you want a fixed measurement or a different challenge, switch protocols—each one trains a slightly different skill.
