Wait
Every signal uses a random delay so memorizing a rhythm does not help.
Reaction Time Game
Build the longest clean streak you can. React after the signal—but one early click ends the run.

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.
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.
