What's your brain age?
Three quick games. About 90 seconds. One number you'll want to beat.
For fun, not a medical test. Scores depend on sleep, your device and practice.
Cognilo: Brain Training Games
Liked that? Cognilo gives you five short brain games a day across memory, focus, logic and numbers, and tracks your personal bests. Untimed by default, about six minutes.
How the brain age test works
You play three short games, each built on a classic measure from psychology research:
| Game | What it measures | Typical adult score |
|---|---|---|
| Reaction | Processing speed: how fast you respond to a change | about 250 to 300 ms in a browser |
| Number memory | Working memory (digit span) | about 7 digits, give or take 2 |
| Mental math | Speed of simple calculation under time pressure | varies a lot with practice |
Speed and working memory are the skills that change most with age, and they're also the ones that swing most with sleep, stress and practice. That's why your brain age is a snapshot for fun, not a verdict.
How to get a younger brain age
Play on the same device, after a decent night's sleep, and try it two or three times. Most people improve quickly as the games become familiar. Daily variety helps too: switching between memory, attention and logic puzzles keeps practice from turning into autopilot.
Questions
How is my brain age calculated?
Each game gives a score: your average reaction time, the longest number you remembered and how many sums you solved in 30 seconds. Each score is compared with rough typical results for different ages, and the three estimates are averaged. It is a game, not a medical or psychological test.
Is a brain age test accurate?
Not in any clinical sense. Your result moves with sleep, caffeine, your device and whether you've played before. Treat it like a fitness test for fun: useful for comparing yourself on different days, not for diagnosing anything. If you're worried about memory or thinking, talk to a doctor.
Why is my reaction time slower on my phone?
Phones and browsers add their own delay, often 30 to 80 milliseconds, before a tap reaches the page. Take the test on the same device each time if you want to compare scores.
What is a good digit span?
Most adults can repeat about 7 digits, give or take 2. That classic finding from psychology is where the phrase "seven plus or minus two" comes from.
Can you lower your brain age?
Your scores usually improve with practice and a good night's sleep. Short daily puzzles that mix memory, focus and logic keep it interesting. That's what the Cognilo app is built around: five short games a day.
Is my score saved anywhere?
Only your best result is saved, in this browser, so you can try to beat it. Nothing is uploaded.
