A square is folded. A hole is punched. Where are the holes?
You see a square folded once, twice or three times, and a hole punched through the folded paper. Your job is to unfold it in your head and say where the holes end up.
Twelve items. There is no timer — this is about what you can picture, not how fast you can picture it. It takes about four minutes. There is no account, no email and nothing to sign up for, and nothing is stored: the test runs entirely in your browser and your answers are never sent to us.
Works with a mouse, a keyboard or a thumb. Twelve items, four folds deep at most.
Before you start
- It measures one narrow thing — whether you can hold a shape in mind and transform it. That is one of several abilities that get called "spatial", and they are not the same ability.
- This task cannot be done without seeing it, and we would rather say so before you start than after four minutes. Where the holes fall exists only in the diagram — a screen reader can say an option has four holes, which is no help at all when every option has four. We have not found an honest way to put a fold sequence into text, and inventing one would change the task rather than translate it. The digit span test announces its digits as text and may suit better.
- The paper is never turned or twisted, and the folded paper always stays inside the edges of the original square. That is part of the task's definition, not a hint.
- Five options, so a blind guess is right about one time in five. Over twelve items that is roughly two correct by luck alone, and we publish that so you can subtract it rather than being sold the whole number as skill.

Your result
What that says about the task
What this task tested
Holding a shape in mind and transforming it — folding, unfolding, and tracking where a point goes while the shape changes. That ability has a name in the psychometric literature: visualization, and paper folding is one of its classic marker tasks.
This is a domain score, not a BrainScore. A single task in a single domain does not make a composite, and we are not going to invent the rest of it.
Your seven scores make one shape. Take the other tests and this number becomes one arm of your Cognitive Fingerprint — seven arms and a single number between 0 and 100. That number says how far you got through what these four tasks can measure. It is not a percentile and not a comparison with other people, and every constant behind it is published, including the one we chose rather than derived.
What this did not measure
It is not a general test of "spatial ability", because there is no such single thing to test. The standard reference kit for cognitive factors separates visualization — what this task samples — from spatial orientation and from spatial scanning, and gives each its own marker tests. A test of one is not a test of another, which is most of the reason two spatial scores disagree.
It also says nothing about navigation, about whether you can read a map, or about anything outside this task.
How much should you trust this number? What moved it that is not you, what it legitimately supports, and what it cannot.
Things that moved this number that are not spatial reasoning
- Screen size. The fold diagrams are small. On a phone, a three-fold item is genuinely harder to read than it is on a laptop, and that is the screen rather than you.
- Whether you used a strategy. Tracking the hole through each fold in turn is a method, and knowing the method helps. That is a real difference between two people and it is not a difference in capacity.
- Guessing. Five options, so about one in five is right by chance. Over twelve items that is roughly two.
- Repeat attempts. Scores on cognitive tasks tend to rise on a second administration without any underlying change, and retest gains keep growing until about the third attempt. A second run is not progress.
Should you believe this number?
What it legitimately supports: that on this task, today, on this screen, you correctly unfolded this many of twelve squares. That is a real measurement of a real thing, and it is narrow on purpose.
What it cannot support: any statement about how you compare with other people. We have measured nobody, our reference sample is zero, and a count with nothing to compare it against is not a ranking. The methodology page sets out exactly where we are on the norming ladder.
And a point the canonical source makes better than we could. The publisher of the standard cognitive-factor test kit states of its own instruments that they are "research instruments not intended for use in selection or counseling" — and requires anyone using them to warrant that they and anybody they pass them to will use the scores properly. If that is true of the properly normed originals, it is true several times over of a free test on the internet, ours included.
If another site gave you a different spatial score, both can be right. We set out exactly where the difference comes from — starting with the fact that "spatial" names at least three different abilities.
Two questions, if you have twenty seconds
We are trying to find out whether explaining a result is worth doing at all. Nothing is recorded except which buttons you press — no result, no identifier, nothing that could be traced to you. There are no wrong answers here and nothing follows from your choice.
1 · Did the explanation above make sense to you?
2 · Did it tell you anything about yourself?
Recorded. Thank you — that is genuinely useful.
Comparing this run with another one
Your score today is one measurement under one set of conditions. The useful thing is not to repeat it immediately — it is to repeat it once under conditions you can name and tell apart: rested against tired, a large screen against a phone, a quiet room against a noisy one.
One thing makes that comparison less clean than you might hope. The items are generated fresh every run, but the kinds of fold repeat, and scores on cognitive tasks tend to rise on a second administration whatever the conditions — retest gains are consistent enough across studies to be a standard methodological problem. A rise is the expected direction. It is not a finding about your conditions.
You do not have to write it down. Name the conditions for the run you just did and we will hold it on this screen while you do a second one.
What next
- Take this again under conditions you can name — a different time of day, or rested rather than tired. That is the only comparison this site can honestly offer you, and it is a comparison with yourself.
- The instrument register — every task we publish, its version, its norming rung and its reference sample.
- How BrainScore works — what we measure, how a task becomes a score, and what the score cannot tell you.
- Claims standards — the language we ruled out in advance, including the comparisons we will not make.
How this is scored
Published in full, because a score you cannot check is not worth much.
The task
- A square is folded one, two or three times. Broken lines show where the paper was; solid lines show where it is now. The paper is never turned or twisted, and the folded paper always stays within the edges of the original square.
- After the last fold, one hole is punched through every layer.
- You choose, from five squares, the one showing where the holes fall when the paper is unfolded.
- Twelve items: four with one fold, four with two, four with three. They are presented in that order, so the task gets harder rather than jumping about.
- There is no timer. Nothing about your score depends on your device, your connection, or whether this tab was in the background.
Where the items come from
We generate them. We do not reproduce anyone else's. The paradigm — fold, punch, unfold — is a standard one and it is described in the published literature. The items themselves in the reference kit are licensed, and reproducing them would be both a licensing breach and a way of quietly making our test somebody else's test. Ours are built from a fold sequence and a punch position each run, which is also why you cannot learn the answers between attempts.
Every generated item is checked before it is shown: the number of holes must be exactly two to the power of the number of folds, the punched cell must appear among them, and re-folding the answer must collapse back to a single cell. An item that fails any of those is not shown to you.
The scoring rule
- Your score is the number of items you answered correctly, out of the number you saw. That is the whole rule. There is no weighting by fold depth, no partial credit, and no hidden modifier.
- A wrong answer is wrong. It does not subtract, and it does not end the test.
- Chance is published rather than hidden: five options means a blind guess is right about one time in five, so roughly two of twelve come from luck alone.
- The result also reports how you did at each fold depth separately, because one, two and three folds are different amounts of the same demand and a single number hides that.
Exclusion rules — when an attempt does not count
- A run stopped early is scored on the items you completed, and the result says how many that was. It is not scored as though the remaining items were wrong.
- A run abandoned by closing the tab is not scored at all; nothing is kept.
- There is no hidden-tab rule here, and that is not an oversight. Our two timed instruments void an attempt if the tab is hidden, because browsers slow timers in background tabs and that hands you a longer look than the task allows. This task has no timer, so hiding the tab changes nothing about it. We would rather say that than carry a rule that does nothing.
The bands
| Correct of 12 | What the result says about the task |
|---|---|
| 11–12 | Three folds held as reliably as one |
| 9–10 | Two folds solid, three folds mostly following |
| 6–8 | The single fold is secure, the deeper ones intermittent |
| 3–5 | Above what guessing produces, and the folds are not yet tracking |
| 0–2 | At or near what guessing alone produces |
These boundaries are a design decision, not an empirical finding. The bottom band is set where it is because five options over twelve items puts pure chance at about two. The rest divide the range by fold depth, because that is the structure the task was built with. When real data exists they will be revisited, and the methodology version will increment when they are. The norming ladder, and where we are on it, is published in full.
What we do with your answers
Nothing. The test runs entirely in your browser. Your answers and your result are never sent to us and never stored. Closing the tab destroys them. The privacy notice covers this in full.
