Game logic
The first sequence contains three digits. Each correct round adds one digit; the run ends on the first incorrect submitted sequence.
🧠 MEMORY TEST
How many digits can you hold in your head?
Three digits becomes four. Four becomes five. Eventually your brain files a complaint.
MEMORY SEQUENCE
Ready?
Memorise the digits. Each round adds one more.

HOW THE GAME SCORES
Number Memory Sequence
Memorise an increasingly long number, wait for it to disappear and reproduce it using the on-screen keypad.
Reading your score
The meaningful score is the longest sequence you actually completed correctly, not the length of the failed sequence. Rounds cleared are also shown separately.
Worked example
If you complete 3, 4, 5 and 6 digits but fail on 7, the completed level is 6 and four rounds were cleared.
Good to know
This browser game is not a clinical working-memory assessment. Screen size, distraction and strategy can influence performance.
UNDERSTAND YOUR RESULT
Digit span is a narrow window into short-term memory
Remembering a growing sequence of digits uses attention, temporary storage and often strategy. The score is interesting, but it is not a complete measure of intelligence or memory health.
What the task asks you to hold
A digit-span style task presents a short sequence, removes it, then asks you to reconstruct the order. That makes order memory just as important as remembering the individual digits.
Chunking changes performance
People often group digits into pairs, dates or familiar patterns. That can improve performance because the remembered units become larger chunks rather than isolated characters.
Attention is a major variable
A notification, conversation or momentary lapse during presentation can destroy a sequence. Repeated attempts under similar conditions are more informative than a single failure.
Memory has multiple systems
Short-term digit recall is not the same as remembering names, learning a skill or recalling events from years ago. A low score here does not mean “bad memory” in general.
| Signal | What it is useful for | Important limitation |
|---|---|---|
| Longest sequence | Peak span in this format | Sensitive to lucky trials |
| Typical span | Repeated range | Better personal baseline |
| Chunked span | Strategy-assisted performance | Shows technique as well as storage |
| Long-term memory | Not measured here | Different memory systems |
Do not turn a game into an IQ test
Working-memory tasks can correlate with other cognitive measures in research, but a browser digit game is not a standardized intelligence assessment.
