About This Test
The Number Memory Test measures your working-memory span: several unique digits flash at random grid positions, then hide — recall them by clicking in ascending order.
Starting from 3 digits, each passed level adds one. It's harder than plain digit recall: you must remember the values, their positions, and sort them at the same time — a dual challenge of span and spatial memory.
Most adults span 5–9 digits; consistently passing 8+ is excellent. Everything runs in your browser and your score can enter the leaderboard (anonymously if you prefer).
How It Works
- 1Click the area to start — digits flash in a grid for about 1.5–3 seconds (longer for more digits)
- 2After they hide, click their original positions in ascending order
- 3A wrong click fails the round: two consecutive fails at the same length end the run
- 4Each passed level adds one digit, starting from 3
- 5Final score = the maximum digits you passed; climb the Top 100 leaderboard

FAQ
What does this test measure?
Working-memory span: holding digits, their positions and sorting them simultaneously — harder than plain digit span tests.
How many digits can most people remember?
Most adults span 5–9 digits. Passing 7–8 consistently is above average; 9+ is excellent.
Why does the flash time vary?
More digits get a longer look (about 1.5–3 seconds) so difficulty comes from the count, not the time.
Does one wrong click end the run?
No — you retry the same length once. Two consecutive fails at the same length end the run.
Can my score reach the leaderboard?
Scores submit automatically; make the Top 100 and you can leave a name or stay anonymous.
