Five quick benchmarks: reflexes, aim, and memory. Every score comes with a percentile.
A reaction time test measures how quickly you respond to a visual stimulus, in milliseconds. The screen turns red and tells you to wait. After a random delay it flips to green, and your job is to click or tap the instant it does. We run five rounds and average them, because a single round is too noisy to mean much. The average human clocks in around 250 to 280 milliseconds. Under 220ms is genuinely quick, and under 180ms puts you in the territory of professional esports players and athletes.
Beyond raw reaction speed, this page includes four more brain benchmarks. The aim trainer measures hand-eye coordination across 20 targets. Sequence memory tests how long a growing pattern you can hold in your head. Number memory measures your digit span, where the average person survives about 7 digits. And the chimp test is a working memory challenge made famous by a Kyoto University study in which young chimpanzees outperformed university students at memorizing number positions. Every result comes with a percentile so you know exactly where you stand.
Somewhat. Sleep, hydration and caffeine each shift reaction time by 10 to 30 milliseconds, and practice makes your results far more consistent. Memory scores respond well to technique: chunking digits into groups and verbalizing positions both help. Your personal bests are saved in your browser, so come back and see if your morning brain beats your evening brain.
