A four-part memory test you can take in a few minutes
This memory test bundles four quick games that each stretch a different kind of short-term memory. Sequence memory lights up coloured pads with matching tones, Simon-style, and adds one step every round. Number memory flashes a number and asks you to type it back, one digit longer each time. Visual memory flashes a pattern of tiles on a grid that grows as you level up. Verbal memory shows a stream of words and asks whether you have seen each one before.
Each game ends after a mistake (or after three lives in the visual and verbal games), and your score goes into a history chart so you can see whether practice, sleep or time of day makes a difference. A table under the chart gives a rough sense of where a score sits — clearly marked as illustrative, because it is a guide written for this page, not data from a study.
It is a game for curiosity and practice. It is not a medical or cognitive assessment and cannot diagnose anything. Everything runs in your browser; your results are stored only on your device.
How to use the Memory Test
- Choose a game: Sequence, Number, Visual or Verbal. A short instruction appears in the play area.
- Press Start test. Sound is on by default for the sequence tones — use the Sound button to mute.
- Sequence: watch, then click the pads (or press keys 1–4) in the same order. Number: memorise the digits, then type them and press Enter.
- Visual: after the tiles go dark, click every tile that lit up; three wrong tiles cost a life. Verbal: press Seen or New (or the S and N keys) for each word.
- When a game ends, read your score and band, check the history chart, and press Try again.
Memory Test features
Four kinds of memory
Auditory-visual sequences, digit span, spatial patterns and word recognition — the same families of task used in classic memory research, in short game form.
Simon-style tones
The four pads play the notes of a C-major chord (C4, E4, G4, C5), so you can remember the sequence as a tune as well as colours. Sound starts only after you press a button.
Adaptive difficulty
Sequences grow by one step, numbers by one digit, and the visual grid grows from 3 × 3 to 7 × 7 with more tiles to remember.
Digit-by-digit feedback
After a number round the tool shows which digits you got right and which were wrong or missing, so you can tell a transposition from a lapse.
History chart
The last 30 results of every game are charted with your best score marked, and stay in this browser between visits.
Keyboard and touch
Pads, tiles and buttons are at least 44 px, keys 1–4 and S/N work on a keyboard, and animations calm down when your system prefers reduced motion.
What each game measures
| Game | What you do | Score | Related idea |
|---|---|---|---|
| Sequence | Repeat a growing pattern of lights and tones | Longest sequence repeated | Serial recall (like the Corsi block task) |
| Number | Recall a number shown for 1 s + 0.5 s per digit | Most digits recalled | Forward digit span |
| Visual | Click the tiles that flashed for one second | Highest level completed | Visuo-spatial working memory |
| Verbal | Judge each word as seen or new | Correct answers before three mistakes | Recognition memory |
What the research says about memory span
In 1956 George Miller described the “magical number seven, plus or minus two”: most adults can repeat back around seven digits. Later work, notably Nelson Cowan’s 2001 review, suggests the true limit is nearer four meaningful chunks, and that people reach seven or more digits by grouping them — 58 21 93 is easier than 582193. That is why the illustrative table for number memory centres on seven digits.
Scores move with sleep, stress, distraction and practice, so treat any single result loosely. If a game feels too easy, notice the strategy you are using; if it feels hard, try saying items under your breath or grouping them in threes.
Tips for better scores
- Sequence: hum the notes. A tune is easier to hold than a list of colours.
- Number: chunk digits into pairs or triplets and read them as numbers (“fifty-eight, twenty-one…”).
- Visual: look for shapes — a corner, a diagonal, an L — rather than single tiles.
- Verbal: picture each word briefly; vivid images are recognised more reliably than sounds alone.
- More brain games: the memory card game trains matching pairs, and the reaction time test and math practice game train speed.
Memory Test FAQ
Is this memory test accurate?
It measures your performance in these four games reliably, but it is not a standardised psychological test. The percentile bands are illustrative, not measured from a population, so use them only as a rough guide.
What is a good score on the number memory test?
Around seven digits is typical for adults, in line with Miller’s “seven, plus or minus two”. Nine or more usually means you are chunking digits well.
Can this test diagnose memory problems?
No. It is a game and cannot diagnose memory loss, dementia, ADHD or anything else. If you are worried about your memory, talk to a doctor.
Why did the test stop when I switched tabs?
Timed rounds are paused and reset if the page is hidden, because the flashes would play while you could not see them. Verbal memory has no timer, so it simply waits.
Are my results saved?
Yes, in your browser’s local storage only: the last 30 results of each game. Clear history removes them, and nothing is uploaded.
Does practice improve memory test scores?
Usually yes, mostly because you learn better strategies such as chunking and rehearsal. Gains in a game do not necessarily carry over to everyday memory.
