What the test measures

The test is built like the reasoning sections of longer IQ tests. It mixes four kinds of question so that no single skill decides your score.

Pattern reasoning (9 questions)
Find the rule in a 3×3 grid of shapes and pick the missing piece.
Number sequences (6 questions)
Spot how a row of numbers grows and give the next one.
Verbal and logic (6 questions)
Word pairs, the odd one out and short logic puzzles.
Spatial (5 questions)
Turn a shape in your head and tell it apart from its mirror image.

The questions get harder within each part. There is no time limit, but the clock shows how long you take; most people finish in 10 to 20 minutes.

How your IQ score is worked out

We count your right answers and place them on the usual IQ scale, where the average is 100 and the standard deviation is 15. Because this is a short test that has not been normed on a large, representative group, we show a likely range about 7 points either side of your number. Read it as "roughly where you are", not as an exact score.

Tips for a fair score

FAQ

Questions people ask

Is this IQ test really free?
Yes. There is no email form, no sign-up and no paid unlock. Your score, percentile, part scores and the explanation for every question appear as soon as you finish.
How accurate is a free online IQ test?
It gives a rough estimate, not a clinical score. A real IQ test is given one to one by a psychologist, takes an hour or more and is compared against thousands of people of your age. This 26-question test has not been normed that way, so we show a range of about 7 points either side and you should treat it as a fun check, not a diagnosis.
What IQ score do you need for Mensa?
High-IQ societies such as Mensa take people who score in the top 2% on an approved, supervised test. On the common scale with a standard deviation of 15 that is about 130; on a scale with a standard deviation of 24 it is about 148. An online test like this one cannot qualify you. If you score in the high 120s or above here, a supervised test is the next step. This site has no connection to Mensa.
What is a good IQ score?
IQ tests are set so the average is 100. About half of people score between 90 and 109, about 16% between 110 and 119, about 7% between 120 and 129 and about 2% score 130 or more. "Good" depends on what you compare against, and an IQ score leaves out a lot, such as creativity, knowledge and how well you get along with people.
What kinds of questions are on an IQ test?
Most tests mix pattern puzzles (find the missing piece in a grid), number series, word problems such as analogies and the odd one out, and spatial tasks like turning a shape in your head. This test has all four, and every puzzle was written for this site.
Can I take the IQ test again?
Yes, as often as you like, but your second score will usually be higher because you have seen the questions. For a fair number, count your first try.
