Number Memory Test
Remember the number. Type it back.
How to Play
Your score is the longest number you can recall.
What is the Number Memory Test?
The number memory test shows you a number, hides it, and asks you to type it back. It starts at four digits and adds one each level until you slip. This is the digit span task from the Wechsler Adult Intelligence Scale, one of the oldest and most widely used measures of short-term memory in psychology.
What's a good score?
| Rating | Score | Percentile |
|---|---|---|
| Exceptional Memory | 12+ digits | Top 1% |
| Excellent | 10–11 digits | Top 10% |
| Above Average | 8–9 digits | Top 30% |
| Average | 6–7 digits | Top 50% |
| Below Average | Under 6 digits | Bottom 50% |
Frequently asked questions
What is a good number memory score?
The average adult digit span is about seven digits, so most runs on this test stall between levels six and eight. Recalling 8 or 9 digits puts you in the top 30%, and 12 or more is top 1%. Scores naturally vary a little from day to day with focus and fatigue.
How can I remember longer numbers?
Chunk them. The number 481519 is six separate digits, but 48-15-19 is only three pieces. Grouping digits into pairs or triples, or mapping them onto familiar dates and patterns, compresses what your memory has to hold. This is the standard technique and it can add several digits to your span.
Why does the test start at four digits?
Four digits sits comfortably under almost everyone's limit, so early levels confirm you understand the task rather than testing you. The difficulty comes from the steady climb: each level adds a digit, and most people feel the strain right around their true span of six to eight.
Does digit span measure intelligence?
It correlates with working memory capacity, which in turn relates to fluid intelligence, but a single span score is a narrow slice of cognition. Clinicians use digit span mostly to screen attention and short-term memory, not to estimate IQ. Treat it as one data point, not a verdict.
