Number Memory test
Remember the number.
A number appears briefly. Type it back. Each round adds a digit. Three lives.
Needs to read a number on screen and type digits.
How this is measured
A number is shown, then hidden. Type it back. It stays visible for 1 second plus half a second per digit (at most 10 seconds), with a progress bar. Digits are random — leading zeros included.
You start at 3 digits; each correct answer adds one. A wrong answer costs a life and gives you a new number of the same length. Three lives; the run ends at 30 digits.
Scoring
score = longest number recalled correctly (digits)
Only an exact match counts. Your answer and the correct number are shown side by side after each round.
What can affect the result
- Chunking strategies (groups of three or four) help a lot.
- Distractions while the number is visible.
What this does not mean
- Digit span is one narrow skill that improves with practice. It is not an intelligence or memory-health measure.
- It is not a medical, psychological, neurological or hiring assessment, and it cannot diagnose or screen for anything.
