High averageLikely range 109 to 127
The amber band is the likely range. Take a second version of the test and the score would most likely land inside it. The curve shows how scores are spread across people, with 100 in the middle.
What the test asks
There are no vocabulary or general knowledge questions. Each of the 32 questions is a figure, a run of numbers or letters, or a puzzle in symbols, and each area starts easy and gets harder. Every question is original, and a solver has confirmed that each has exactly one defensible answer.
| Area | What it measures | Questions |
|---|---|---|
| PatternsGrids of figures with one cell missing | Fluid reasoning | 10 |
| SeriesRuns of numbers and letters | Inductive and number reasoning | 8 |
| SpatialTurned and folded shapes | Visual-spatial reasoning | 7 |
| LogicOrdering and deduction in symbols | Deductive reasoning | 7 |
| Total | 32 | |
How the score is worked out
Scored on our server
Your answers are marked on our server. The answer key never reaches your browser, so nobody can fake a score by reading the page.
Placed on the standard scale
Scores use the usual IQ scale, where 100 is the average and the standard deviation is 15.1
Reported with a margin of error
A test of 32 questions can't tell 117 from 119, so every score comes with its likely range, as professional testing standards ask.2
Built from published rule types
The pattern questions combine the rule types researchers identified in matrix tests of figures. Harder questions combine more rules.3
Clear about its limits
The norms are provisional until enough people have taken the test to recalibrate it. Scores are shown from 70 to 145, because a short test can't measure precisely beyond that.

Questions people ask
Is this IQ test free?
Yes. Taking the test is free, and so is your result: the score, the band it falls in and its margin of error. We don't ask for an email address. A fuller results pack is optional and costs $6.99, paid once.
What is in the results pack, and what does it cost?
$6.99. One payment. No subscription. It adds your exact percentile and place on the curve, a score for each of the four areas, a written report on your own answers, an explanation of every question, and a named PDF certificate with a serial number anyone can check. Refunds are given on request within 14 days.
Are there hidden fees or a subscription?
No. There is one thing to buy, the results pack at $6.99, and its price is shown before you pay. It is one payment, not a subscription, and nothing renews. You never give card details to see your score.
How long does it take?
About 25 minutes. There are 32 questions and a 25-minute limit, set so that most people finish. You answer one question at a time and cannot go back.
How accurate is an online IQ test?
Treat the score as an estimate. It comes with a likely range, and its norms are provisional until they can be recalibrated from real answers. A test given in person by a psychologist is longer, covers more abilities, and is the only kind that should inform a decision about school, work or health.
Is this a clinical test?
No. It is for interest, and it is for adults. It is not a clinical assessment, it cannot diagnose anything, and it does not stand in for a professionally administered test. It was not designed for children, and it is not for anyone under 13.
What does the score mean?
The score places you on a scale where 100 is the average. About 68% of people score between 85 and 115, and about 95% score between 70 and 130. A score of 115 is higher than about 84 in every 100 people.
