Sequence Memory Test
Wards flare gold in a sequence — watch the order, then plant them back by clicking the same spots in the same order. Perfect it and the next sequence is one longer. Two failed attempts end the run.

What's a good score?
8–9 span — Exceptional spatial sequence memory.
6–7 — Strong — above the classic average.
5–6 — The textbook adult range.
< 5 — Typical when tired or distracted; span is state-sensitive.
What this test measures
This is the Corsi block-tapping task, in continuous use since 1972 — the standard measure of visuospatial sequence memory. The classic adult span is around 5–6 items; the task’s beauty is that it self-calibrates, climbing until it finds your ceiling.
Spatial working memory is one of the clearest expert–novice separators in esports research samples — and it shrinks when you’re tired, which is why it’s one slot of our daily readiness check.
Why your span is lower than 7±2
Almost everyone has heard that human memory holds seven items, plus or minus two. That figure came from verbal material — digits and words — and it does not apply here. Spatial sequence spans run lower, typically five to six in adults, because remembering positions in order uses a different and smaller system than remembering a phone number.
So a span of five on this test is not a poor result against the famous number. It is a normal result on a different scale, and comparing the two is the most common misreading of a spatial span score.
The task self-calibrates, which is its real elegance: it climbs until it finds your ceiling rather than asking everyone the same question. Whatever level you fail at is, by construction, the edge of your capacity today.
Strategy is most of your score
Raw capacity is fairly fixed. How you encode is not, and that is where the improvement lives.
- Chunk into shapes, not points. A four-step sequence that traces a rough triangle is one item if you see the shape and four if you see four spots. This is the single biggest lever, and it is why practised scores climb well past the naive ceiling.
- Encode direction, not just position. Storing the path — up, across, down-left — compresses a sequence into a motion rather than a list.
- Do not verbalise positions. Naming spots routes spatial information through a slower verbal channel and tends to cost you at longer spans.
- Watch the whole board. Tracking each flare individually with your eyes means you are reconstructing rather than perceiving the shape.
Honest caveat, same as everywhere on this site: what improves is your performance on span tasks. Whether it makes you better at remembering a rotation in game is not established, and we are not going to pretend otherwise.
Span is one of the most fatigue-sensitive numbers here
Working memory span shrinks measurably with fatigue and divided attention. Losing a full item between a rested day and a bad one is unremarkable — and against a baseline of five or six, one item is a large proportional loss.
What makes it useful as a signal is that the loss is not subtle to the person experiencing it. Unlike a slower reaction time, which feels like nothing, a shrunken span feels like the sequence simply evaporating. People notice. They usually attribute it to not concentrating, which is close: maintenance in working memory is effortful, and effort is exactly what a bad night takes away.
Spatial working memory also separates stronger from weaker players in esports research samples more cleanly than most measures — which is a correlation across people, not a promise about you. What it does justify is measuring it daily, which is one slot of the daily check.
What Corsi measures that digit span does not
This is the Corsi block-tapping task, in continuous use since 1972 and one of the most durable instruments in neuropsychology. Its value is that it isolates the visuospatial side of working memory from the verbal side — two systems that can come apart independently.
The distinction is not academic for a game. Verbal span is remembering a build order someone typed. Spatial span is remembering where three wards went and in what order, or which path a jungler took through your quadrant. The second is the one League actually taxes, constantly, and it is the one this test measures.
It also pairs with a different measurement: our visual memory test measures how many things you can hold at once, with no ordering. This measures order. Under fatigue they degrade separately, which is why both are worth having.
How to take the sequence memory test
- Start the test — Free, no signup, nothing recorded.
- Watch the wards flare in order — Take in the shape of the path rather than individual spots.
- Replant them in the same order — Click the same positions in the same sequence.
- Each success adds a step — Perfect a sequence and the next one is one longer.
- Your span is where you stop — Two failed attempts end the run — the level you reached is your span.
Questions players ask
What is a normal memory span?
Around 5–6 items for spatial sequences in adults (slightly below the famous 7±2 figure, which was for digits). Span shrinks measurably with fatigue and divided attention.
How is this different from a number memory test?
This measures WHERE-in-order memory rather than verbal digits — a separate system, and the one games actually use: positions, paths, and timings on a map.
Can I grow my memory span?
Practice and strategy (chunking positions into shapes) reliably improve span-task scores. Gains are measured on the trained task family.
What is a good sequence memory score?
A span of 5–6 is the textbook adult range, 6–7 is strong and 8–9 is exceptional. Below 5 is common when tired or distracted — span is one of the more state-sensitive measures here.
Why is my spatial span lower than the famous seven?
Because 7±2 was measured on verbal material like digits. Spatial sequences use a different and smaller system, so 5–6 is the correct comparison point. The two scales are not interchangeable.
What is the Corsi block-tapping task?
A visuospatial span test in continuous use since 1972, in which positions flare in sequence and the participant reproduces the order. It is the standard instrument for spatial working memory and the basis for this test.
Does chunking count as cheating?
No — it is the intended skill. Grouping positions into shapes is exactly how practised performers exceed the naive ceiling, and the same strategy appears in every span-task literature. Capacity is fixed; encoding is not.
How is this different from the visual memory test?
This one measures order — the sequence is the content. The visual memory test measures how many items you can hold simultaneously with no ordering at all. They rely on related but separable systems and degrade differently under fatigue.
