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.
