What this memory test measures
This informal tool measures one narrow task: forward digit recall during this session. You see a number and reproduce it in the same order after it disappears. It can help you observe your own performance under similar conditions, but it does not measure all forms of short-term or working memory.
How scoring works
The challenge begins at 3 digits and can reach 20. Your highest span is the longest length you complete correctly. Accuracy is correct rounds divided by all submitted rounds. A wrong answer retries the same length, and three mistakes end the session. The best saved in this browser is a local device record, not a global comparison.
Factors that affect this attempt
Sleep, attention, interruptions, recent practice, screen visibility, input comfort, and other display conditions can shift a result. A single run is a snapshot. For a cleaner personal comparison, use the same device and setting, remove distractions, and take breaks when concentration drops.
Reasonable ways to practice
Practice briefly and deliberately: read the whole sequence, group digits only if that helps you stay consistent, enter them without rushing, and stop before fatigue turns practice into guessing. Repeating the task may improve familiarity with the format, so improvement does not automatically mean a broad change in memory.
Limits of the result
This result cannot be used to infer IQ, overall memory ability, health, or a diagnosis. It is not a clinical instrument and cannot replace a professional assessment. If memory changes are persistent, concerning, or affect daily life, speak with a qualified professional.

Frequently asked questions
How does the memory test work?
A sequence appears briefly, then disappears. Enter the digits in the same order. In screen reader mode, the test waits for you to confirm that you have heard the sequence before showing the input. Correct answers move to a longer sequence; an error retries the same length.
How is the score calculated?
Highest span is the longest length completed correctly. Accuracy is correct rounds divided by all submitted rounds, and the session ends after three mistakes.
Why do I retry the same number of digits?
A wrong answer uses one of three mistakes but keeps the same length, so one miss does not immediately increase or reduce the challenge.
Why can my result change between attempts?
Sleep, attention, interruptions, practice, and display conditions can all affect this session, so compare attempts made under similar conditions.
Does this test measure IQ or diagnose a condition?
No. It measures only forward digit recall in this session. It cannot establish IQ, overall memory ability, health, or a diagnosis, and it does not replace professional assessment.
Is my memory-test data uploaded?
No. The test runs in your browser and only the best span is stored locally on this device. That device best is not a global comparison.
Can I use the test on a phone?
Yes. The interface supports phone screens and numeric input; keeping the device, display, and surroundings consistent makes personal retests easier to compare.
