How to take the free IQ test
This test uses matrix puzzles, the picture-pattern format found in many nonverbal reasoning tests. You do not need any vocabulary or school math: only the ability to notice rules and apply them. Puzzles start easy and get harder, and harder puzzles count for more points.
- Find a quiet place and about 20 minutes. Press Start the test, or Space.
- Study the 3 by 3 grid. Look along each row and down each column for what changes: shape, number of figures, rotation, shading, color or size.
- Pick the option that completes every rule at once, by tapping it or pressing 1 to 6 (or A to F). Press Enter or Next to continue.
- Skip a puzzle that takes too long; you can go back with the Back button or the left arrow before the timer ends.
- Read your estimated IQ range, percentile, time and strengths by area. Share the result as an image or print a certificate with your name.
How the puzzles and the score work
Each puzzle is built by code from rules: the shape, the number of figures, their rotation, shading, color and size can stay the same, change by a fixed step along a row, or appear once in every row and column. The missing square is the only option that obeys all the rules, and every other option breaks at least one of them.
Puzzles come in four difficulty tiers, from one changing feature up to four. Correct answers on harder tiers are worth more points. Your weighted score is placed on a scale with a mean of 100 and a standard deviation of 15 to give an estimated IQ range and percentile. The test number in the address (?seed=) recreates exactly the same puzzles.
What's a good IQ score?
On the usual IQ scale, 100 is the middle and most people score between 85 and 115. The table shows the common descriptive bands and roughly how many people fall in each. Remember that an online practice test only gives an estimate.
| Estimated IQ | Description | Share of people (approx.) |
|---|---|---|
| 130 and above | Very high | About 2% |
| 120–129 | High | About 7% |
| 110–119 | High average | About 16% |
| 90–109 | Average | About 50% |
| 80–89 | Low average | About 16% |
| Below 80 | Below average | About 9% |
Useful tips and limitations
- Check rows first, then columns: most puzzles combine two or three rules at the same time.
- Before you look at the options, picture what the missing square should contain. Then find the option that matches.
- Take the test when you are rested; tiredness affects pattern reasoning more than most people expect.
Common questions
Is this an official IQ test?
No. It is a practice test for fun and self-study. Official IQ scores come from standardized tests given by a trained psychologist. Our estimate is a rough guide based on a typical score, not a diagnosis.
Why do I get a range instead of one number?
Every test has some measurement error, and a 30-question online test more than most. The range shows where your score is likely to fall, which is more honest than a single exact number.
Does practicing matrix puzzles raise my IQ?
Practice makes you faster and more familiar with the format, so your score on this kind of test can rise. That reflects skill with the puzzles, not necessarily a change in general intelligence.
Why are harder puzzles worth more points?
Weighting rewards solving complex patterns, which separates scores more fairly than counting every puzzle the same. An easy puzzle is worth 1 point and the hardest are worth 4.
How is the time limit used in my result?
The timer limits the test to 20 minutes and your time is shown with the result. The IQ estimate itself comes from your weighted score, so you do not lose points for using the full time.
