These games do not all test the same memory
Short-term memory is not one store but several, and the five tools here land in different ones. Number Memory loads the verbal loop — the store that holds things you can say to yourself — which is why saying digits aloud helps and background chatter hurts. Visual Memory Test loads the visuospatial store instead, holding where things were rather than what they were called, and speaking does nothing for it.
Sequence Memory adds serial order, which is stored separately again — you can be certain a tile was in the pattern and still place it wrong. Memory Match is the only one that runs over minutes rather than seconds, so it tests how much survives between turns. And the Chimp Test compresses everything into a single glance, measuring what one very brief exposure can carry.
Where to start
- First time here: Number Memory. It is the most familiar format and the score is immediately interpretable.
- Playing with someone else: Memory Match, the only one where an adult and a beginner compete on genuinely close terms.
- Wanting a score that improves within one sitting: Sequence Memory. Most people add two or three levels in their first ten attempts.
- After something genuinely hard: the Chimp Test, which almost everyone fails earlier than they expect.
- Curious about spatial rather than verbal memory: the Visual Memory Test, which is the one that says least about how well you handle numbers.
What a score here does and does not show
Practice raises these scores quickly, and that is worth being clear about. Improving at any of these games mostly means learning its particular trick — grouping digits, tracing a path, anchoring to corners — and those techniques transfer to the same task rather than to memory in general. The research on commercial brain training has repeatedly found the same pattern: large gains on the trained task, very little beyond it.
What the scores are genuinely good for is comparison with yourself. Run the same test at the same time of day for a week and the variation will track your sleep and your attention far more closely than anything about your memory capacity, which barely moves.
Frequently asked questions
What is a good memory test score?
Rough averages: 7 digits in number memory, level 8–10 in visual memory, 8 steps in sequence memory, and 7–9 in the chimp test. Beating those puts you above most players.
Do memory games actually improve memory?
You will clearly improve at the task itself through better strategies (chunking, verbalizing positions). Whether that transfers to everyday memory is still debated in research — treat these as fun measurement, not medicine.
What's the difference between the visual memory and chimp tests?
Visual memory only asks which tiles lit up; the chimp test also demands the order, binding each position to a number — that extra binding is what makes it harder.
What's the difference between short-term and working memory?
Short-term memory is passive storage — holding a phone number just long enough to dial it. Working memory is storage plus manipulation: holding information while you reorder, compare or use it. Repeating digits mainly taxes the first; the chimp test leans toward the second, since you must hold positions while executing them in order.
Which memory test should I start with?
Start with number memory — it's the simplest format and gives you a clean baseline (most people land near 7 digits). Then try visual memory for positions and sequence memory for order. Save the chimp test for last: it combines position and order, so it's the toughest and the most satisfying to improve at.
Why is it called the chimp test?
It recreates a famous Kyoto University experiment in which young chimpanzees memorized the positions of numerals after seeing them for only a fraction of a second — and outperformed adult humans at the task. The test became a viral benchmark precisely because losing to a chimpanzee makes people want another round.
