How it works: each game is scored against typical results at different ages: reaction speed and short-term memory both change with age. Your three game ages are combined into one brain age. It’s a bit of fun, not a medical test. Updated .

How old is your brain?

Three quick games, about 2 minutes. Find somewhere quiet and give it your full attention.

Three games: speed, memory and focus. About 2 minutes, and your result is free.

How to

How to find your brain age

  1. Speed. Tap the box when it turns green, five times. Your average reaction time is compared with typical times at different ages.
  2. Memory. A number flashes up, then disappears. Type it back. Each time you get it right, it gets one digit longer. You have two lives.
  3. Focus. Two shapes appear. Are they exactly the same, colour included? Answer as many as you can in 20 seconds. Wrong answers count against you.
  4. Get your brain age. Each game gives an age, and the three are combined: speed counts a little more than the others.
  5. Compare and challenge. Add your real age to see the difference, then send the link to a friend to see whose brain is younger.

About the test

What is brain age?

“Brain age” is a fun way of describing how quickly and accurately you’re thinking right now, compared with typical people of different ages. Some thinking skills, especially processing speed and working memory, tend to peak in early adulthood and slowly change from middle age onwards, while knowledge and vocabulary usually keep growing for decades.

This test looks only at the fast, “fluid” skills, so a low brain age means you were quick and sharp today. It doesn’t measure wisdom, knowledge or intelligence, and the same person can score quite differently when tired, distracted or on a different device.

What affects your result?

Sleep, focus and practice make the biggest difference: most people improve over their first few goes. Phones are a little slower than a mouse for tapping, so the speed game allows for that. Noise and distraction mostly hurt the memory game.

Brain ageWhat it means
Under 23Turbo brain. Exceptionally quick and sharp today.
23–29Sharp. Faster than most people.
30–39In its prime. Quick, steady and accurate.
40–49Steady. A solid, typical result.
50–59Seasoned. Try again when you’re fresh and focused.
60 and overTaking it easy. Tiredness, distraction or a slow device can all push this up.

Can you lower your brain age?

Your score on this test, yes: a good night’s sleep, a quiet room and a couple of practice goes usually bring it down. For your brain in general, the NHS points to regular exercise, staying social, a healthy diet and keeping your mind active. Our free daily brain training is a fun way to do the last one.

FAQ

Frequently asked questions

Is this brain age test free?
Yes. Your brain age and the age for each game appear the moment you finish. There is no sign-up, no email and nothing to pay.
How is my brain age worked out?
Each of the three games (speed, memory and focus) is compared with typical results at different ages and gives an age of its own. Your brain age combines them: speed counts for 40% and memory and focus for 30% each.
Is brain age a real thing?
Not as a medical measurement. It is a fun way of comparing how quick and sharp you are today with typical people of different ages. Skills like processing speed and working memory really do change with age, but the result also depends on sleep, focus and your device.
Is this a dementia or memory test?
No. It is a game for fun and cannot tell you anything about your health. If you or someone close to you is worried about memory problems, talk to a GP.
What is a good brain age?
Anything younger than your real age is a great result. Under 30 means you were quick and accurate today; 40s and 50s are common, especially on a phone or when tired.
Why is my brain age older than my real age?
Usually tiredness, distraction, a slow device or simply not having warmed up. Most people score younger on their second or third go. Try again somewhere quiet when you are fresh.
How many digits can most people remember?
Most adults can repeat back about 7 digits, give or take two. Remembering 9 or more is very good.
Does it work on a phone?
Yes. Touchscreens register taps a little later than a mouse, so the speed game allows for that on phones.
Can I lower my brain age?
Your score, yes: sleep well, find a quiet spot and have a practice go first. Playing the daily brain training games keeps you sharp, and regular exercise and staying social are good for your brain in general.
How do I challenge a friend?
After your result, tap WhatsApp, Messages or Copy link under Challenge a friend. Your friend plays from the link and sees whose brain is younger.
What is the daily board?
Your first finished go each day goes on a board of the day's youngest brain ages, under your nickname. It resets at midnight UK time. Later goes that day are practice and only count for your personal best.
Is anything stored or uploaded?
The games run in your browser. Your results and real age (if you add it) are saved only on your device. Your first go each day sends your brain age and nickname to the daily board; a challenge link only contains your brain age.
Can I use the keyboard?
Yes. Press space in the speed game, type the number in the memory game, and use the left arrow (same) and right arrow (different) in the focus game.
