Questions

Frequently asked questions

What does Number Memory measure?+

Short-term and working memory capacity—how many digits you can hold and recall in order.

Why does the sequence get longer so fast?+

The game adds one digit per level to keep you at the edge of your capacity, which is where adaptation happens.

How do I reset my score?+

Refresh the page or clear local storage to start from level 1.

Does hardware matter?+

Minimal—any device with a clear screen works. Focus and strategy matter far more.

How long should I practice?+

5-10 focused attempts per day is enough. Stop when accuracy tanks to avoid encoding bad habits.
