Color Hue Test

The average human visual reaction time sits around 200–270 ms; competitive gamers often land below 180 ms. These tests give you a clean number for each skill — simple reaction, raw clicking speed (CPS), target acquisition and how finely you can tell colors apart.

Reaction time is sensitive to sleep, caffeine and time of day, so test at different times and watch your average, not your single best. Every test here feeds a global leaderboard if you want to compete.

Frequently asked questions

What is a good reaction time?
200–250 ms is solid, under 200 ms is fast, and under 170 ms is elite territory. Note that your monitor and input device add their own delay.
How can I click faster in the CPS test?
Most fast clickers use jitter clicking (tensing the forearm) or butterfly clicking (alternating two fingers). Casual clicking lands around 6–8 CPS; 10+ takes technique.
Why do my results vary between attempts?
Reaction speed fluctuates with alertness, fatigue and even screen refresh rate. Take five attempts and use the average — that's what our tests report.
What factors affect reaction time?
Age is the big long-term one — reaction time is typically fastest around the late teens and twenties, then slows gradually. Day to day, sleep, fatigue, caffeine and time of day move the needle most, and your hardware adds a constant offset: a high-refresh monitor and a low-latency mouse shave real milliseconds off your score.
Why does reaction time matter for gamers?
In shooters and fighting games, duels are often decided by who responds tens of milliseconds sooner — seeing an enemy peek or an attack animation and acting first. But raw reaction is only one ingredient: aim accuracy, game sense and positioning matter at least as much, which is why the aim trainer sits next to the reaction test here.
In what order should I use these tests to train?
Start each session with the reaction test to set a baseline while you're fresh, then do a CPS round for raw speed, and spend the bulk of your time on the aim trainer — accuracy is the skill that improves most with practice. Finish with the color test occasionally; it measures perception rather than speed, so it doesn't need daily reps.
