5 quick games test your reaction time, memory and processing speed — then you get your BrainScore and see how you compare to everyone else. Free, no sign-up, about 5 minutes.
BrainScore is a fun benchmark, not a clinical IQ test.
How quickly your brain turns seeing into doing. Linked to alertness and motor speed. Average is around 273 ms.
Your working-memory span for digits — the same idea as the classic digit-span test psychologists use. Most people manage about 7 digits.
How long a pattern you can hold and reproduce in order. Tests sequential working memory.
How many positions you can photograph in your mind at once. Tests visuospatial memory.
Processing speed under pressure — compare each symbol to the previous one, fast. Inspired by the symbol-matching tasks used in cognitive research.
All five results are standardized against typical performance and combined into one IQ-style score where 100 is average.
Play each game once before the full test. First attempts are almost always your worst.
Remember 8 3 5 2 9 1 as "835 – 291". Chunking is how memory athletes handle long digit strings.
In visual memory, sweep the grid in a fixed order (left to right, top to bottom) instead of trying to see everything at once.
Hover your finger and relax. Tensing up adds 20–30 ms. And no, you can't beat ~150 ms — that's human nerve-speed territory.
No. It's a fun cognitive benchmark inspired by tests psychologists use, but it's not a clinical IQ test. It measures reaction time, short-term memory and processing speed on an IQ-style scale where 100 is average.
Each game result is compared against typical population performance and converted to a standard score. The five scores are averaged and mapped to a scale with mean 100 and standard deviation 15 — so 115 means better than about 84% of people.
Yes — all games and your BrainScore are free, no sign-up. The optional one-time Premium unlocks a detailed per-skill report, a printable certificate and progress tracking.
Completely. Everything runs in your browser. Results are stored only on your device and never uploaded.
Definitely. These skills are trainable and most people improve a lot within a few attempts. Premium keeps your history so you can watch your progress.
Tiredness, distractions and unfamiliarity with the games all lower scores. Try again rested, in a quiet moment, after one warm-up round. Scores are for fun — don't read too much into any single run.
