Reaction time test
Wait for the panel to turn green, then click. Five randomized rounds produce one local average. Your display, browser and input path are part of the result.
Five randomized rounds
False starts are discarded.
Use the result as a baseline, not a diagnosis
BenchRush measures browser-visible input. If a result looks wrong, repeat the run, check focus and settings, compare another browser/device where practical, and use manufacturer diagnostics for hardware conclusions.
Questions people ask
What is a good reaction time?
There is no universal browser number that fairly compares every setup. Treat your result as a personal baseline first, because display refresh, input path and browser timing affect the measurement.
Why do five rounds?
Multiple rounds reduce the impact of one lucky or distracted click and make repeat runs more useful.
Is this a medical or cognitive test?
No. It is a browser game benchmark and should not be used to assess health, cognition, driving fitness or neurological status.
