Sequence Memory Test
Repeat an ever-growing sequence of tiles until your working memory taps out.
How to Take the Test
The sequence memory test works like the classic electronic pattern game, stripped down to a clean measurement. A set of tiles lights up one after another; when the sequence finishes, you click or tap the same tiles in the same order. Reproduce it correctly and the next round replays the sequence with one more step added to the end. The sequence keeps growing — one new tile per round — until you make a mistake, and the length of the longest sequence you reproduced is your score.
Because the sequence extends rather than resets, the test measures how long an ordered pattern you can hold and update, not just how many positions you can glimpse at once. At the end of a run you see your score with a percentile that places it against published distributions for this type of task, so you know how your span compares rather than guessing. The test runs locally in your browser with no account or signup, and your results are saved on your device for comparison across sessions.
What the Score Measures — Honestly
Sequence memory probes ordered visuospatial recall — keeping track not only of which tiles lit up but in which order. Order information is fragile: most failures on this test are transpositions, where you remember the right tiles but swap two steps. That makes it a different measurement from a static pattern test, and a useful complement to one. Keep the interpretation honest: a single run is a noisy estimate, scores move with fatigue and attention, and practicing this test makes you better mainly at this test. Improvements here do not automatically translate into remembering errands or names — the research on what transfers and what does not is summarized on our brain training page, and it is worth five minutes before you read anything grand into a score.
Practical Tips
- Turn the sequence into a path. Do not store tiles as a list of positions — watch the sequence as a route being traced across the grid and replay the route. Spatial paths survive in memory far longer than abstract lists.
- Rehearse during the playback, not after. Each round replays the existing sequence before adding a step, and that replay is free rehearsal. Follow along actively instead of waiting passively for the new tile.
- Group steps into rhythmic chunks. Three or four steps per chunk, like the way phone numbers are spoken, lets a twelve-step sequence live in memory as four items instead of twelve.
Frequently Asked Questions
How is my score calculated?
Your score is the length of the longest sequence you reproduced correctly. The run ends on your first mistake, and the percentile compares your result against published distributions for this kind of task.
What is a typical sequence memory score?
Most adults break down somewhere around the high single digits to low teens of steps. The percentile shown with your result is the most reliable yardstick for where you stand.
How is this different from the memory matrix test?
Memory Matrix flashes a static pattern all at once and asks which tiles lit up. Sequence memory adds order: the tiles light one by one and you must reproduce the exact sequence, which is a distinct and more fragile kind of recall.
Why do I keep failing by swapping two steps?
Transposition errors are the signature failure of ordered recall — order information degrades before item information. Chunking the sequence into small rhythmic groups is the standard countermeasure.
Will practicing raise my score?
Yes, on this task, mainly through better chunking strategies. That is genuine skill, but evidence that it transfers to memory in daily life is weak, so treat the score as a measurement rather than training progress.
Do I need an account?
No. The test runs entirely in your browser, and your score history is stored locally on your device.
