Wait for the box to turn green, then click as fast as possible. Clicking too early resets the round.
This test measures your simple reaction time — the delay between seeing a visual signal (the box turning green) and your finger clicking. It is measured in milliseconds (ms), and the result reflects your raw neural processing speed plus mouse and display latency.
Your best of several tries is the fairest number, since one lucky click can mislead.
In shooters like Valorant and CS2, a 50 ms reaction advantage decides duels. But raw reaction speed is only part of it — positioning, crosshair placement, and game sense matter just as much. Use this test to track your form, not to judge your skill.
Reaction time varies naturally with focus, fatigue, and anticipation. Take 5 tries and use your average — that is your real number.
Yes, measurably. Higher refresh rates show the green signal sooner, and lower input lag means your click registers faster. The difference between 60Hz and 144Hz is typically 10–20 ms.
Clicking before green is a false start. The round resets so anticipation can’t fake a fast score. Wait for the color change.
