The test at a glance
| Question | Answer |
|---|---|
| What it checks | Working memory (digit sequences forwards and backwards), attention with response inhibition, and reasoning with patterns. |
| Who it's for | Children aged 5–16. Task length and pace adjust to age: 5–7, 8–11 and 12–16. |
| How long it takes | About 7 minutes: three games of 2–3 minutes each, with a break between them. |
| Do you need to sign up | No. You enter the child's age (the name is optional), and before starting a parent ticks the consent box and types their own name. |
| What the result is | On screen straight away, for each game separately: level, accuracy in per cent, response time and task details. |
| What it doesn't diagnose | It's an educational screening, not a medical or psychological diagnosis. It doesn't measure IQ or detect ADHD, dyslexia or other conditions. |
| What you need | A browser, nothing to install. A computer or tablet is most comfortable. |
| Who made it | Space Memory, an online school (GLOBAL LEADERS SKILLS Sp. z o.o., Warsaw), using classic cognitive psychology tasks. |
What exactly the three games check
Memory is one task in the test, but not the only one: a child who got distracted also “forgets”, so the memory score is read together with attention.
- Space Numbers — working memory — Digits appear on screen one by one; the child types them in the same order, then backwards. After correct answers the sequence gets longer. Backward recall is harder: the material has to be not only held but rearranged — as in mental arithmetic or multi-step instructions.
- Space Adventure — attention and inhibition — The child responds to some objects and has to hold back on others. This Go/No-Go task shows whether attention holds until the end of the game and whether the child can stop an automatic response.
- Pattern Planet — reasoning — Completing the missing piece of a pattern, as in matrix puzzles. The short test only has the easier boards, so it checks whether the child grasps the rule rather than measuring their limits.
How the result is calculated
No comparison with other children — only what the child did in these tasks, on that day.
- Accuracy — The share of correct answers in the main part, excluding practice. 80% in Space Numbers means four out of five sequences were recalled without a mistake.
- Forward and backward span — The longest digit sequence recalled correctly in each direction, for example 5 digits forwards and 3 backwards.
- Response time — The average time of correct answers in milliseconds — lower is faster. It depends on the device, so repeat measurements on the same one.
- Level — Getting started, Learner, Star or Super Hero — thresholds written into the task, the same for every age. In Space Numbers, “Star” means at least 7 digits forwards and backwards combined with accuracy of 70% or more.
The result isn't a percentile and doesn't say how many children of that age did better. We don't give that comparison because we don't have collected norms that would justify it. We only show numbers you can check against the task itself.
How to take the test so the result means something
Six things to do before pressing “start”. They take a minute and decide whether the numbers can be trusted.
- Pick a time when the child has energy
Not after a full day of school and training. A test taken at ten at night measures tiredness, not memory.
- Sit down at a computer or tablet
A bigger screen and a comfortable keyboard cut down mistakes that have nothing to do with memory.
- Quieten the room
A television and talk in the background lower memory scores more than you would think. Silence is part of the procedure, not a whim.
- Explain that this is not an exam
There are no marks and nothing to pass. A child who fears the result rushes and loses points to the rush.
- Do not prompt during the test
Even a gesture or a sigh changes the result. Best to sit nearby, but out of sight of the screen.
- Take the test again in a month
One measurement says nothing about change. Only two, taken at a similar hour, show a direction.
If the child stops halfway or starts clicking at random, break off and come back another day. A result like that describes nothing but tiredness.
How to read the memory result
Four things worth knowing before you draw conclusions.
A strength is information, not a reason to relax
A good result in Space Numbers means the child keeps order well — build on that: step-by-step plans, lists, repeating aloud.
A lower score is a direction of work
Not a label. Memory span grows with age, and part of the school load can simply be taken off onto paper.
One day is one day
Sleep, mood and attitude can move the result. That is why a repeated measurement counts, not a single one.
What the result does not tell you
There is no diagnosis here, no IQ figure, and no answer to whether the child “will cope in high school”.
What to do with the result
Three typical pictures and the shortest way forward.
| What the result looks like | What to do |
|---|---|
| Memory strong, marks poor | The cause is more likely the way of studying than memory |
| Backwards clearly weaker than forwards | Work on taking the load off working memory |
| All three games low | Repeat the measurement another day, then talk to the teacher |

Privacy: what happens to the data
Short and specific — schools and counsellors ask us this most often.
- What we don't need — Email, phone, an account or a card. The child's name is optional; the age is enough.
- Where the result stays — A guest's result is saved in the browser on that device and is not sent to the school's server. Clearing the browser data deletes it.
- When it reaches the server — Only if a Space Memory student logs in on that device — then the result goes to their profile and their coach can see it.
- Counters — Advertising tools (Google Analytics, Meta) run in the test only after consent to cookies. Visits to this page are counted by Umami — no cookies and no child data.
- Sharing — The “Share” button sends this page's address, never a result. The test's address contains no data about a child's result.

For schools, blogs and counsellors: how to recommend the test
You can put a link to the test on a school website, a blog or in a message to parents. A plain link is enough — no frame, scripts or tracking tags:
<a href="https://space-memory.com/en/memory-test-for-kids-online/">Free memory test for kids — Space Memory</a>- No permission needed — You don't need to write to us or sign anything. The test is free for families who come to it through you, too.
- Ready-made description — You can use this sentence: “A free game-based test for children aged 5–16: working memory, attention and reasoning in about 7 minutes, no sign-up. An educational screening, not a diagnosis.”
- What we ask you not to write — That the test diagnoses, measures IQ or compares a child with peers — it does none of these.
Who made the test
The test was made by the Space Memory team — an online school that teaches children memory, concentration and study techniques (GLOBAL LEADERS SKILLS Sp. z o.o., Warsaw). The tasks aren't our invention: digit sequences forwards and backwards, Go/No-Go and matrices are classic cognitive psychology tasks used in research for decades. We put them into a space setting a child understands and a short browser version.
Parents' questions
Is the test really free?
Yes. The short test — three games, about 7 minutes — is free and needs no account. We don't ask for a card, email or phone to show the result. The full test, with six games and a detailed profile, is for families with an account.
From what age can it be taken?
From 5 to 16. Task length and pace adjust to the age you enter: differently for 5–7, 8–11 and 12–16. Younger children usually need a parent nearby for the instructions.
Is it a diagnostic assessment?
No. It's an educational screening showing how the child did on that day. Diagnoses are made by specialists using entirely different procedures.
Is the result an IQ score?
No. The test doesn't measure intelligence and doesn't convert the result to any IQ scale.
Does a high level mean my child has a good memory?
A high level means the child handled the digit sequences well that day. It's not a comparison with peers or a verdict on memory “in general” — remembering texts or pictures are different skills.
Can the test be repeated?
Yes, and it's worth it — after a month or two, at a similar time of day and on the same device. On a repeat some tasks are familiar, so a small gain can be practice; a clearer change says more.

Want to help your child practise memory?
In online classes the child learns memory techniques on their own school material: 90 minutes once a week, in a group of 5–10. The manager will tell you the terms and the timetable of the next group.
