Your result, straight away
An estimated IQ with its likely range, your percentile, and the rules behind every puzzle.
A score with its margin of error
No 30-question test can pin intelligence to a single number, so we do not pretend to. You get an estimate and the range your true score probably falls in, drawn on the curve of the whole population.
- Standard scale. Mean 100, standard deviation 15, the scale used by modern tests.
- Scored by pattern, not just count. Solving hard puzzles counts for more than solving easy ones.
- Honest about its limits. The range it can measure, and what it cannot tell you, are stated on your result.

Why “upfront”
The usual pattern
You answer every question. Then the score is locked behind a $1 “trial”, and the small print signs you up to about $30 a month. A UK consumer group logged dozens of complaints about this in a single quarter.
How these traps workWhat we do instead
- Your score is shown before we ask you for anything.
- We never take an email address or card details.
- The method, the scoring and the limits are published.
- Results are not stored: they live in a link only you have.

Questions people ask
Is this IQ test really free?
Yes. You see your estimated IQ, your percentile, the likely range and an explanation of every puzzle the moment you finish. There is no email wall, no card form and no subscription.
Do I have to pay or enter an email to see my score?
No. The score is worked out in your browser and shown immediately. We never ask for an email address or payment details, so there is nothing that could be charged later.
How long does the IQ test take?
There are 30 puzzles and a 25-minute limit. Most people finish in 15 to 20 minutes. Two unscored practice puzzles come first.
How accurate is an online IQ test?
Less accurate than a supervised assessment, and any site that says otherwise is overselling. A 30-puzzle test has a margin of error of roughly 11 points either way, which is why your result is shown as a range. Unsupervised scores also tend to run slightly high.
What does the test measure?
Figural reasoning: finding the rules in patterns you have not seen before. It is the kind of task most closely tied to general intelligence, but it is one ability, not the whole of it. It does not test vocabulary, memory or knowledge.
What is a good IQ score?
The average is 100 by definition. About two thirds of adults score between 85 and 115, and about 95% between 70 and 130. A score of 115 is higher than about 84% of people; 130 is higher than about 98%.
Can I use this result to join Mensa?
No. Mensa states that online tests cannot be used for admission; it requires an approved, supervised test with a score at or above the 98th percentile. This test can tell you whether a supervised test might be worth your time.
Are the puzzles copied from another test?
No. Every puzzle is generated from published rule types (progressions, distributions and overlays). None is taken from Raven’s Progressive Matrices, the Wechsler scales or any other copyrighted test.
Is my result stored?
Not by us. Your answers stay in your browser, and the result lives in a link that only you have. If you lose the link, the result is gone.
