How to play

Wait for the panel to switch from standby to GO, then activate it immediately.

Controls

Click, tap, or press Space when the GO signal appears.

Rules & result

Five valid attempts produce an average. Early input counts as a false start.

Scoring tip

Relax your hand, watch the whole panel, and react to the state change.

How Reaction Relay works

Browser timing and pointer events measure each attempt locally. Results are used only for the current run and an optional personal record. Restart creates a clean state without reloading the page, and optional records remain on this device.

Accessibility and devices

The game uses visible text feedback in addition to color. Controls are keyboard-focusable, touch targets are at least 44 pixels, and motion is reduced when your system requests it.
