Nonverbal IQ Test: A Free 20-Item Matrix Quiz in the Culture Fair Style
A free, untimed matrix quiz with 20 original figures for adults curious about reasoning without words. Each item shows a grid with one tile missing and four candidate figures, and your result is a count of correct answers placed in a broad estimated range, with a four group breakdown and an optional PDF. Most people finish in about 15 minutes.
Reviewed byMichael Callans, MSWNonverbal IQ Test (Culture Fair Style) is a free, confidential 20-question self-assessment, original matrix quiz · Not a culture free measure. It takes about 6 minutes, runs entirely in your browser, and gives you a plain-language score across 4 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.
What this nonverbal quiz actually measures
This is a short figure quiz for education and self-reflection. Every item shows a three by three grid of tiles with the bottom right tile missing, and asks which of four candidate figures completes it. Nothing in the figures has to be read, which is what the phrase culture fair points at, and it is worth being straight about the limits of that phrase: removing language reduces cultural and educational influence, it does not remove it. There is no evidence that any test is culture free, and familiarity with puzzles, years of schooling and simple practice at taking tests still show up in a count like this one. Each figure carries a written description, so the quiz can also be answered with a screen reader; if you would rather take a text-only quiz instead, that is our IQ Test: Free Reasoning Quiz. The series, odd-one-out and rotation version of the figure format lives on Pattern Recognition Test (Figures). All 20 figures here were drawn for this page and are not reproduced from any published matrix test.
Matrix completion, drawn not written
Every item is a grid with one tile missing and four candidate figures below it. The rules are the generic ones the matrix format has always used: a feature changing along a row or down a column, two features changing at once, each value appearing once per row and column, and figures combining or canceling. The figures are ours, the correlation between these 20 items and any published test has never been measured, and 20 items sample a very small slice of reasoning.
Four item groups, our own grouping
Single-rule, two-rule, distribution and addition or subtraction matrices carry five questions each. These are our own editorial groupings, not validated subscales and not four separate scores. They are there so you can see which kind of rule was harder to spot on this attempt, which is more useful than a single number and much less likely to be over-read.
Fixed cutoffs, no population ranking
Your number correct is placed in a broad estimated range of quiz performance using fixed editorial cutoffs, not comparison with a standardization sample. This self-administered, untimed, unproctored quiz is unnormed. Its ranges are not IQ bands, percentiles, diagnoses, or statistical confidence intervals, and even a perfect result cannot be quoted as a nonverbal IQ score from Psychology.com.

How scoring works
Answers are scored 0–20 in total. Your result falls into one of 4 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–5 | Limited to partial quiz success: an estimated range | Most of these grids did not give up their rule on this attempt. This range describes the quiz, not your standing against other adults. |
| 6–10 | Partial to moderate quiz success: an estimated range | You found the rule in a fair share of these grids and lost it in others. The middle of our scale does not mean the population average. |
| 11–15 | Moderate to broad quiz success: an estimated range | You solved most of these grids, including several where two rules had to hold at once. |
| 16–20 | Broad to near-complete quiz success: an estimated range | Almost every grid here resolved for you. This quiz has run out of room rather than found your limit. |
Where the term culture fair came from
The phrase goes back to Raymond Cattell, who argued in 1940 for a test built from shapes and relations rather than words, on the reasoning that a figure puzzle asks nothing about the language, schooling or general knowledge a particular group happens to share. The same idea produced the nonverbal matrix tradition that most people picture when they think of an IQ test: a grid, a missing piece, a set of candidates. Cattell originally used the words culture free, then moved to culture fair, which is already a retreat from the stronger claim.
It was the right retreat. Matrix tests are not free of culture or education. Years of schooling, exposure to puzzles, how often a person has sat a multiple-choice test and simple familiarity with the convention that a grid should be read left to right and top to bottom all influence performance. Raven's own review of cross-cultural and cross-time data on matrix testing makes the same point from the other direction: these scores move with context. We use the phrase in the title because it names the format people are searching for, and we add the word style because the claim underneath it does not hold. Familiarity cuts both ways, which is why the common sense test asks about everyday safety, money and social situations instead of grids.
What the Flynn effect showed about these tests in particular
Across the twentieth century, average performance on standardized cognitive tests rose substantially in every country with the data to check, roughly three points per decade on the usual scales. Flynn's 1987 survey of fourteen nations is the paper that put the pattern beyond argument, and his later book works through what it means.
The detail that matters here is which tests rose fastest. The gains were largest on the most abstract, least knowledge-dependent tests, the figure matrices above all, and smallest on tests of acquired knowledge such as vocabulary and arithmetic. That is the exact opposite of what you would expect if the abstract tests were measuring something culture free: a measure insulated from environment should be the one that stays still while the knowledge tests drift. Whatever matrix tests capture, it responds to something about the modern environment, probably including schooling and the habit of thinking in abstract categories. That is the single best reason to treat a strong count on this page as interesting rather than as a fact about your nature. For a mixed set rather than figures alone, the quick IQ test runs twelve original reasoning questions and returns an estimated range of quiz performance.
How the four item groups were built
Single-rule matrices change one feature along a row or down a column: how many dots, how large the shape, which way a line points. Two-rule matrices change one feature across and a different one down, so the missing tile has to satisfy both. Distribution matrices give each of three values exactly one appearance in every row and every column. Addition or subtraction matrices put two figures together in the third tile of a row, or show what is left when the second is taken out of the first.
Those rule families are public property and have been used for the best part of a century. The figures themselves are not. Every grid, every candidate and every wrong answer on this page was drawn for it, and the three wrong candidates on each item are always near misses rather than filler, so a guess is a real guess. With four choices, random guessing earns a point roughly one time in four, and the total is not corrected for guessing. The four groups carry five items each; they are our own unvalidated categories and their difficulty has not been calibrated, so one taller bar does not prove a stronger underlying ability. Every item on our verbal IQ test was written for it too, with thirty original questions that each put the word inside a short sentence.
What to do after this quiz
For the other half of the figure format, Pattern Recognition Test (Figures) uses series, odd one out and rotation instead of matrix completion. The same kind of rule-finding written out in words is the Abstract Reasoning Test.
A mental rotation task, where you decide whether two drawn objects are the same shape turned around, sits on Spatial Reasoning Test (Mental Rotation). For a longer general quiz with several question types in words, see the IQ Test: Free Reasoning Quiz.
If what brought you here was a professionally administered nonverbal assessment, that is a different errand. Nonverbal instruments exist precisely for situations where language, hearing or a speech difficulty would confound a verbal test, and they are given one to one by a licensed psychologist who can watch how a person works, not only what they answer. Ask a primary care clinician for a referral and ask the psychologist which instrument they use and what the evaluation will answer. A professional result can differ substantially from this quiz in either direction. If you were after a job-style mixture of numerical, verbal and logical questions instead, the Aptitude Test is the nearest page we have.
Methodology & sources
This is an original educational figure quiz, not an administration or adaptation of a published nonverbal test. The Cattell Culture Fair Intelligence Test and Culture Fair III, Raven's Progressive Matrices and Raven's Advanced Progressive Matrices, the Test of Nonverbal Intelligence Fourth Edition, the Naglieri Nonverbal Ability Test and the Universal Nonverbal Intelligence Test are named here only to say what this page is not: no figure, item or candidate set is reproduced, paraphrased, rotated, recolored or renumbered from any of them, and we have no license to reproduce any of them. The generic rule families the format uses are public; the drawings are ours. The research cited below explains where the culture fair idea came from and why it did not survive contact with the evidence. None of it supplies these items or validates this quiz, and we have no validation study, standardization sample, age norms or reliability estimate of our own.
All 20 items have four candidate figures, with one correct answer worth 1 and three incorrect answers worth 0. There are no reversed items, no time limit, no speed bonus and no adjustment for age or education. The total is the number correct out of 20. Fixed editorial cutoffs of 0 to 5, 6 to 10, 11 to 15 and 16 to 20 assign broad estimated ranges of quiz success; they are educational groupings rather than clinical cutoffs, confidence intervals or population norms, and one answer at a boundary can change a label without a meaningful change in ability. Single-rule, two-rule, distribution and addition or subtraction matrices carry five items each. Those four groups are our own unvalidated categories, not validated subscales and not four separate scores. Every figure carries a written description detailed enough to answer the item without seeing it, which also means the quiz can be completed with a screen reader.

Nonverbal IQ Test (Culture Fair Style) FAQ
Is this nonverbal IQ test free, and is it timed?
It is free, and there is no timer. The 20 figures, the on-screen estimated range and the four group breakdown cost nothing and need no signup or email. Most people finish in about 15 minutes, but you can take as long as you like, and there is no speed bonus. This page is for adults aged 18 and over. Work it out from the grid rather than from a search or an AI tool, or the result will describe the tool instead of you.
Is this the TONI-4 or another named nonverbal instrument?
No. The Test of Nonverbal Intelligence, Fourth Edition is a professionally administered instrument published for qualified users, and we neither reproduce it nor claim any connection to it. The same goes for the Cattell culture fair tests, Raven's Progressive Matrices, the Naglieri Nonverbal Ability Test and the Universal Nonverbal Intelligence Test. When language, hearing or a speech difficulty would confound a verbal test, what a clinician uses is an individually administered nonverbal assessment, given one to one by a licensed psychologist. This page is an original quiz with 20 figures drawn for it.
Is a nonverbal test really culture fair?
Not in the sense the phrase suggests. Taking language out of the items removes one large source of cultural and educational influence, which is genuinely worth doing, but it does not produce a culture free measure and no such measure has ever been demonstrated. Schooling, exposure to puzzles, practice at multiple-choice tests and familiarity with the convention of reading a grid all still matter. The clearest evidence is the Flynn effect: twentieth century score gains were largest on exactly these abstract figure tests, which is the opposite of how a culture free measure would behave.
Why can an online quiz not reproduce a real timed nonverbal battery?
Because a standardized battery is as much about the conditions as the items. A published nonverbal test is administered one to one by a trained examiner, who controls the order, stops at a defined ceiling, times the session and records how the person worked, not only what they chose. A browser cannot verify who is answering, whether a second window is open, or whether an item was studied for a minute or an hour. Adding a countdown here would only produce a number that looked standardized, which is why this quiz has no clock and says so.
Can my child take this?
Please do not use it for a child. The wording, the result and the limits described here were all written for adults, and a count has no meaning for a younger test taker. If you are wondering about a child's reasoning or learning, the useful step is an individually administered assessment by a licensed psychologist, usually arranged through the school or a pediatric clinic. We do not offer a children's test and are not building one.
Is the test really confidential?
Yes. It runs entirely in your browser. Your individual answers are scored in your browser and are never sent to us or linked to you. They stay in this tab so you can return to your result, and closing or clearing the tab clears them. If you ask us to email the PDF, we receive your summary scores with your email address, never your individual answers. No account is needed.
