About working memory

Working memory keeps information “online” for a few seconds while you manipulate it. It’s critical for reading, mental math, and staying on task amid distractions.

Why this 3×3 test is useful

Training tips

What changes in the brain?

Practice may strengthen fronto-parietal control networks involved in maintaining and updating information, improving resistance to distraction. Gains are usually modest but measurable over weeks.

Scoring & privacy

Your result is the best level reached in a run. Scores are stored locally in your browser; if you use “Your results”, an anonymized copy is saved to a shared store to compute global benchmarks. No personal data is required.

Tip: run at a similar time of day and with similar conditions (sleep, caffeine) to reduce noise in your trend.
