A number appears for a few seconds. Memorize it, then type it from memory. Every correct answer adds one digit. One mistake ends the run, so see how far you can get.
Level 1 shows a single digit. Each time you answer correctly the number gets one digit longer, and the time you get to study it grows a little too. Type the number in the box and press Enter. If you get it wrong, the run ends and you see the correct number next to your answer. Your score is the longest number you got right.
| Digits remembered | Rating |
|---|---|
| 1 - 5 | Below average |
| 6 - 8 | Average, around the classic "seven plus or minus two" |
| 9 - 11 | Above average |
| 12 or more | Excellent, usually needs chunking |
These bands are rough guides, not a clinical test. Your best score is saved in this browser only.
Most adults can hold about seven digits in short-term memory, give or take two. Reaching 9 or more digits without any memory trick is already above average.
Chunk the digits into groups of two or three, like a phone number, and say each group aloud in your head. Linking groups to dates, ages or other numbers you already know also helps.
