Number Memory Test

Memorize a growing number of digits each level. Type it back. Track your best score over time.

Number Memory (Digit Span)

Level: 1 Best: —
Tap Start
You will see a number for a short time. Remember it and type it back.
Quick tip: If the digits feel too long, try chunking — grouping digits into small blocks.

What this test measures

This is a number memory (digit span) test: each level shows a longer sequence of digits for a brief time. Your goal is to recall the exact number. As the digits increase, the task shifts from short-term storage to more active working memory.

How the scoring works

Your score is the highest level you reached (the longest number of digits you recalled correctly). We save your session history on this device so you can track your best and your trend. If you want a quick benchmark, see what counts as a good number memory score.

How to improve (practical)

  • Chunking: group digits into small blocks (e.g., 4927 → 49 / 27).
  • Rhythm: silently “say” digits with a steady tempo to keep them active.
  • Consistent practice: 2–5 minutes daily beats one long session per week.
  • Reduce noise: do it in a quiet moment; distractions inflate variability.

FAQ

Why do I score lower on my phone?

Phones add more friction (tiny keyboard, interruptions). For fair tracking, compare scores on the same device type.

Does this diagnose memory problems?

No. This is a simple cognitive task for self-tracking and practice, not a medical diagnostic tool.

Is it about intelligence?

Not directly. Digit span reflects attention + working memory, which are important skills, but it is not an IQ test.
