Three quick tasks measure your reaction speed, memory and mental maths, then combine into an estimated brain age. Free and fun — not a diagnosis.
Three quick tasks — reaction speed, number memory, and mental maths — combine into an estimated cognitive age.
⚡ Reaction
🔢 Memory
🧮 Maths
Brain Age combines three short challenges — reaction speed, number memory, and mental maths — into one informal cognitive-age estimate. A lower age means stronger performance on those tasks relative to typical ageing curves. It is a training and curiosity tool, not a medical diagnosis.
Cognitive ageing research shows that processing speed and some memory measures decline gradually after early adulthood, while vocabulary often stays stable or improves. This test samples speed and working memory only — it does not measure wisdom, expertise, or emotional intelligence.
Your result is an index built from three browser tasks. Sleep, caffeine, screen latency, and practice all move the number. Treat a single run as a snapshot, and track trends across weeks rather than obsessing over one score.
Clinicians use far longer batteries under controlled conditions. If you are worried about memory loss, confusion, or sudden change, speak with a GP — do not rely on a free web game.
Reaction time captures simple visual–motor speed. Number memory samples digit span. Mental maths probes arithmetic fluency under time pressure. Together they approximate the “fluid” side of everyday cognitive fitness.
People who train one skill often lift that component without changing the others. Use the domain scores to choose a follow-up drill: reaction-time, number-memory, or mental-math on this site.
Sleep and daylight exercise move processing speed more than any single puzzle. Test when you feel alert, then retest after a week of consistent sleep.
Practise the individual component games daily for ten minutes. Strategy gains (chunking digits, left-to-right maths) show up quickly; raw neural speed improves more slowly.
Avoid comparing phone and desktop scores — input latency differs. Keep the same device when tracking progress.
