Questions and answers

Most people finish in about 12 minutes. There are 25 puzzles and a hard limit of 20 minutes. If you reach the limit, the test submits what you have answered so far.

Reasoning with unfamiliar visual and numeric material, in five sections: Pattern Recognition (5), Abstract Reasoning (9), Spatial Reasoning (5), Quantitative Reasoning (3), Logical Reasoning (3). There are no words to read and no trivia, so vocabulary and schooling matter less than on many tests.

No. Your estimated IQ depends on which puzzles you get right, weighted by how hard they are. Your pace is reported separately as a description and does not change the number. Unanswered puzzles count as wrong, so use the 20 minutes you have.

No. Once you confirm an answer the test moves on, which keeps the timing honest. On a phone you tap once to select and tap again (or press Next) to confirm, so a slip of the thumb does not count.

Your progress is saved in your browser, so reopening the test on the same device picks up where you left off. The time limit keeps running while you are away.

Yes. Every attempt gets newly generated puzzles, so you never see the same test twice. Expect a small bump on a retake: research on cognitive tests finds that retaking raises scores by about a quarter of a standard deviation on average, roughly 4 IQ points. We suggest waiting 30 days.

No. IQ Octopus does not ask your age and does not apply age norms the way clinical tests do. It is designed for adults. Clinical scores compare you with people your own age, so keep that difference in mind when you compare numbers.

IQ Octopus gives an estimate and shows it as a range, not only a single number. Even clinical IQ tests given by psychologists report a confidence interval, often around plus or minus 5 points at 95%, because every test carries some measurement error. An online test adds more uncertainty, since you take it unsupervised, on your own device, with whatever distractions are around you.

Alongside your overall estimate, the full result rates each of the five sections on a 1 to 10 band with a plain label, so you can see where you were strongest. Section scores rest on fewer puzzles than the overall estimate, so treat them as a rough profile.

Partly because scales differ. Most modern tests use a standard deviation of 15, but older Stanford-Binet forms used 16 and the Cattell Culture Fair III scale uses 24, so the same percentile prints as a different number. Tests also measure different mixes of abilities, and every score carries measurement error.

No. Mensa accepts people who score in the top 2% on an approved, supervised standardized test. IQ Octopus is not one of those tests. It also cannot be used for school placement, disability assessment or employment screening.

No. It is not a clinical or diagnostic instrument and is not given by a psychologist. If you need an IQ score for a diagnosis, an accommodation or an official purpose, a licensed psychologist can give you a standardized assessment.

Yes. Your result page has a share link and an image card. The shared view shows your score, percentile and curve only, never your section details, and you can turn sharing off.

Taking the test is free and needs no sign-up. When you finish, your full result costs $4.95 one time: your estimated IQ, percentile, confidence range and five-area breakdown. There is no subscription and nothing renews.

Scoring and hosting cost money, and we do not sell your data or run ads. Charging once for the result is how the site pays for itself.

Stripe handles payment on its secure checkout page. You can pay by card, and wallet options such as Apple Pay or Google Pay appear when your device supports them. The charge shows as IQCURVE on your statement.

No. You do not create an account or give an email to take the test. If you buy the full result, Stripe asks for an email at checkout and we send your permanent result link there.

Your answers, how long each one took, and the email you use at checkout. We do not run ads and we do not sell personal data. Stripe processes payments, so we never see your card number.
