How fast, exactly? The floor crews average 180 milliseconds.
Five trials. The panel arms, holds for an interval you cannot predict, then fires the go signal. Touch the panel the instant it fires — the gap is measured in milliseconds and the median of five is filed. Touch it while it still reads HOLD and the false start is filed too. Everything is.
No download. No account. Five trials, under a minute. The panel does not warn twice.
Mouse, finger, or spacebar — the panel accepts any of them. It forgives none of them early.
The full audit runs in the game. Free. Anonymous until you claim a seat.
Frequently filed questions
Is this reaction time game free?
Yes. Free, browser-playable, no sign-up, no download. Five trials, the median is filed on the spot, and the result stays on this page.
How is the reaction time measured?
The panel arms, holds for an interval you cannot predict, then fires the go signal. The gap between the signal and your touch is measured in milliseconds with the browser's high-resolution clock. Your screen and input device add their own latency, so compare runs on this page — not against laboratory numbers.
What counts as a false start?
Touching the panel while it still reads HOLD. The trial restarts, the false start is filed, and the rating pays for it. The protocol does not distinguish between nerves and intent.
Is this a real reflex or medical assessment?
No. It is a game. The rating is a game score for entertainment — it does not measure reflex health, diagnose anything, or stand in for any professional assessment. The 180-millisecond figure is the filed average of the game's floor crews, not a human benchmark.
What is Last Control?
A multiplayer browser game in which you run a base of workers under a protocol that audits everything — including you. The full 60-second cognitive audit at game.last-control.com is the entrance.
