What's a Good Memory Score? Realistic Benchmarks for All Three Modes

You've just finished a round on the Chimp Test, Sequence Memory, or Number Memory and you want to know one thing: is that number good? The honest answer is that it depends which mode you played, because each one loads a slightly different part of working memory and scales its difficulty differently. Below are realistic benchmarks for all three, plus the classic psychology research that these games are, loosely, all riffing on.

Chimp Test: tile count

The Chimp Test starts at 4 tiles and adds one more each round, so your score is simply the highest count you cleared before a wrong click ended the run. In practice:

0–3 tiles — didn't survive the opening round. Completely normal on a first attempt; the layout is unfamiliar and the tiles vanish the instant you start clicking.
4–5 tiles — average. Most first-time players land here once they understand the rules.
6–7 tiles — sharp. You're reliably encoding spatial position for six or seven vanished targets, which is a solid working-memory result.
8–9 tiles — excellent, and where most regular players eventually plateau with practice.
10–11 tiles — exceptional, genuinely rare territory for a human being tested cold.
12+ tiles — the name of the game. This is the range that starts to approach what young chimpanzees demonstrated in the research the test is named after (see our history of the Chimp Memory Test).

Sequence Memory: sequence length

Sequence Memory starts with a single flashing tile and appends one more to the pattern each time you reproduce it correctly, so your score is the longest sequence you got completely right, in order.

0–4 tiles — just warming up. This covers a lot of first attempts, since remembering an ordered sequence is a different skill from remembering static positions.
5–7 tiles — average recall, and a comfortable target for casual play.
8–10 tiles — sharp memory, requiring genuine chunking strategy rather than brute-force holding of every tile individually.
11–13 tiles — excellent, where most dedicated players settle after a few sessions of practice.
14–17 tiles — exceptional, well above where most people's sequential recall tops out.
18+ tiles — grandmaster-level recall, and a genuinely impressive feat of sustained sequential memory.

Number Memory: digit count

Number Memory starts at 3 digits and adds one more each round, testing pure digit-span recall with no spatial component at all.

0–5 digits — just warming up, though 5 digits is already a completely ordinary result — this is close to a classic phone-number chunk.
6–7 digits — average recall, and squarely inside the range most cognitive research treats as typical adult digit span.
8–9 digits — sharp memory, at or above the upper edge of what most people can hold without a deliberate strategy.
10–12 digits — excellent, and where practiced players tend to plateau.
13–15 digits — exceptional, requiring real chunking technique (see our guide to improving working memory) to sustain.
16+ digits — savant-level recall, far beyond ordinary unaided digit span.

Where these numbers come from, and where they don't

None of these tiers are drawn from a peer-reviewed study of this specific game — they're informal, editorially-chosen bands meant to give you a sense of scale, and our own terms of use say exactly that. What they're loosely inspired by is real psychology, though, and it's worth knowing the actual research so you can calibrate your expectations honestly.

The most famous number in working-memory research is George Miller's 1956 paper “The Magical Number Seven, Plus or Minus Two,” which surveyed a range of short-term memory tasks and found human capacity clustering around seven items, give or take two. That number has been refined a lot since — later work by Nelson Cowan and others argues the real capacity for held, actively-manipulated information is closer to four chunks, with the higher “seven” figure partly reflecting rehearsal tricks and chunking strategies people apply without realizing it. Either way, the Number Memory scores above line up remarkably well with this literature: 6–7 digits is squarely “magic number” territory, and pushing past 9 or 10 generally means you've started chunking digits into pairs or groups rather than holding each one individually.

The Chimp Test and Sequence Memory load working memory differently — they add a spatial or sequential-ordering component on top of the raw item count — so they aren't directly comparable to a digit-span number. That's part of why all three modes exist side by side: they're a rough, informal cross-section of different facets of the same broader cognitive system, not three ways of measuring one thing.

Why none of this is a clinical measurement

It's worth being direct about what these games are and aren't. They're not validated psychometric instruments, they weren't administered under lab conditions, and your score is affected by screen size, sleep, caffeine, how many times you've played today, and plain luck in which cells the tiles land on. A single round tells you very little in isolation; a personal trend over dozens of rounds tells you a lot more. If you want a number to actually track, watch your own best score and your last-10 history over a few sessions rather than fixating on one run.

If your motivation is genuinely improving rather than just seeing a number go up once, the technique side of this matters more than raw repetition — our guide to improving working memory covers what's realistic to train and what isn't. And if you're curious why this test is named after a chimpanzee at all, the real research behind the name is more interesting than the meme format usually lets on.
