Numbers
Number series. Work out how each step changes the number.

04The process
How it works
Three steps. The first runs in your browser and takes only a few minutes.
Take the full test in the app
An adaptive test that picks each question for you: about 30 minutes, and about 30–40 questions while we calibrate. Your result unlocks in the app when a friend you invite finishes the test there, or with an in-app purchase.

05The scale
What does a score actually mean?
IQ-style scores sit on a bell curve: the average is 100 and the standard deviation is 15. Move the marker to see how a score compares with everyone else.
About two thirds of people score between 85 and 115.
That is why IQ Arion always shows a range around the score: every test has measurement error.
How scoring worksA score of 115 is higher than about 84 out of 100 people.
06Principles
An estimate, not a verdict. Three rules we will not bend, whatever they cost us in clicks.
- 01
Every question is checked
Puzzles are generated from explicit rules. A separate solver rejects any question that does not have exactly one correct answer.
- 02
Same answers, same score
A fixed measurement model turns your answers into an estimate. AI writes the short profile text on your result – it never decides your score.
- 03
No dark patterns
No invented user numbers, no “are you a genius?” headlines.

The Flynn effect: are IQ scores still rising – or falling?
For most of the 20th century, average IQ test scores rose from one generation to the next. Newer data from Norway and the US show a more mixed picture. What the studies actually found.

Questions and answers
Is this an official IQ test?
No. IQ Arion gives an estimated score on the IQ scale, with a confidence interval, based on beta norms from the research literature rather than a representative norm study. It is not a clinical assessment and must not be used for medical, psychological, educational or hiring decisions.
How do I unlock my result?
In one of two ways: when a friend you invite finishes the test in the IQ Arion app, your result unlocks – or unlock it right away with an in-app purchase. Your friend unlocks their own result the same way.
What does the app cost?
The test, duels, daily puzzles and leaderboards are free, with no ads. The only purchase is optional: unlocking a test's full result and certificate – which also unlocks at no cost when a friend you invite finishes the test in the IQ Arion app.
What is Arion AI?
An AI opponent that steps in when no human player at your level is online after about 20 seconds. It is always clearly labelled, picks questions that fit your level and answers a little slower than people at your level usually do – so playing fast and accurately beats it.
Who can use the app?
Anyone aged 13 or older. Where EU law requires it, players below the age of digital consent need a parent's approval before they can play duels and join leaderboards.
