Fast & Accurate IQ Test
One culture-fair test in three lengths: Quick (15 puzzles, about 6 minutes), Normal (30, about 12) or Full (45, about 20). No words, no general knowledge, generated fresh every time. Free to take.
- Quick · 15 questions · about 6 minutes
- Normal · 30 questions · about 12 minutes
- Full · 45 questions · about 20 minutes
Choose how precise you want to be
Same puzzles, same five domains. More questions means a narrower interval around your score, and the Full form adds a per-domain profile.
A fast, accurate IQ test, generated fresh every time
Most online IQ tests reuse one fixed set of pictures, so the answers circulate and the score drifts upward. This test builds its puzzles from a random seed each time you start: the rules stay the same kind (rotation, fill, count, shape, position), the figures never repeat.
Every item has six choices and exactly one correct answer. Each wrong choice breaks the rule in one specific way, and your report tells you which way — so you learn something from every item you miss.
Why culture-fair
No vocabulary, no general knowledge, no reading beyond a one-line instruction. Your result depends on reasoning alone, which is why the same test is served in twenty languages without any translation of the puzzles.
What makes it different
Answer keys never leave the server, every item has the same 60-second limit, and the result states its own precision: a range for the Quick form, a confidence interval for Normal and Full.
Five Cognitive Domains
Six questions per domain in the Normal form. The Full form reports a score for each domain; the shorter forms report the overall IQ.
Fluid Reasoning
3×3 matrices and figural analogies: find the rule that completes the grid.
Pattern Recognition
Figure series and odd-one-out: see what changes from step to step, or what does not belong.
Visual Perception
Picture completion: pick the piece that fits the gap in a tiled pattern exactly.
Quantitative Reasoning
Number grids and sequences: the arithmetic rule behind the numbers, no formulas needed.
Working Memory
A row of figures is shown for one second per figure; then you answer a question about it from memory.
Four Simple Steps
From start to result in about twelve minutes
Pick a length
Quick, Normal or Full: 15, 30 or 45 questions. Every length covers the same five domains.
Solve the pictures
Six choices per item, one correct. You have 60 seconds for each item.
Scored on the server
The puzzles are generated from a seed and scored where the answer key lives, so results cannot be gamed.
Read your report
IQ with its interval, percentile, and for every item the rule and why each wrong choice is wrong; the full report is one payment, no subscription.
How the score is calculated
Each item is worth its difficulty (1 to 5 points), so a hard matrix counts for more than an easy series. Your weighted raw score is converted to a deviation IQ with a mean of 100 and a standard deviation of 15, then to a percentile.
We report the precision with the score. A test's reliability sets the width of its confidence interval: about ±7 IQ points for the 15-item Quick form, ±5 for the 30-item Normal form and ±4 for the 45-item Full form (one standard error, about a 68 % range). The Quick form therefore shows a range rather than a single number.
The norms are provisional: they follow the typical difficulty of this item type and are replaced by norms from our own completed runs once each length has enough of them. Runs that are far too fast, or below chance level, are flagged rather than scored.
For an assessment with verbal and knowledge items too, see our standard IQ test or the Stanford-Binet assessment. The scoring method is described on the methodology page.
What your IQ score means
IQ scores are scaled so that the average is 100 and the standard deviation is 15. On that normal curve about two in three people score between 85 and 115. The table shows how common each range is.
| IQ score | What it means | Share of people |
|---|---|---|
| Below 70 | Well below average | ≈ 2% |
| 70–84 | Below average | ≈ 14% |
| 85–114 | Average | ≈ 68% |
| 115–129 | Above average | ≈ 14% |
| 130–144 | High | ≈ 2% |
| 145+ | Very high | ≈ 0.1% |

The test is free to take. Right after it you see where you stand (your score range), with no sharing and no form. Your exact IQ score and full report are one payment, no subscription. No sign-up or email is needed before your result.
The score is as precise as the length allows and we say so: the Quick form gives a range of about ±7 IQ points, the Normal form ±5 and the Full form ±4 (one standard error, about a 68 % range). Norms are provisional until each form has enough completed runs; no online test replaces an individually administered assessment by a psychologist. Because every item is a picture, language and reading matter much less: picture items reduce language bias, although no test is entirely free of culture.
Yes. 120 is above average: on the normal curve (mean 100, standard deviation 15) about 91 in 100 people score lower, so it sits around the 91st percentile. See what an IQ of 120 means.
Close. 127 is well above average: on the normal curve (mean 100, standard deviation 15) it sits around the 96th percentile. Many gifted programmes use 130, about the top 2 %, as their cut-off, so 127 is just below that line. See what an IQ of 127 means.
72 is below average: on the normal curve (mean 100, standard deviation 15) about 3 in 100 people score lower, so it sits around the 3rd percentile. A score is a snapshot of reasoning on one day, and one online test is not a diagnosis; only an individual assessment by a psychologist can give one. See what an IQ of 72 means.
A culture-fair test measures reasoning, not vocabulary or schooling. Matrices, series, odd-one-out and missing-piece items work the same in every language and are what fluid-reasoning tests such as Raven's matrices rely on.
Yes. Every run is generated fresh from a new seed, so you never see the same puzzles twice and there is nothing to memorise. Practice still helps a little, so the first attempt is the most representative.
Short on time or just curious: Quick. Want a score you can quote with its interval: Normal. Want the most precise score and a profile of your five domains: Full. You can move to a longer form from your results page at any time.
The Standard, Mensa-style, Stanford-Binet, CHC and WAIS assessments each follow a named model and include verbal and knowledge items. This test is the non-verbal, generated one: the right choice when you want a result that does not depend on language, and the quickest to retake.
