Free IQ test with matrix logic puzzles
Pick the shape that completes each grid. 15 questions adapt to your level, then you see your estimated score.
How the test works
- Each question is a grid of 9 boxes whose shapes change by a rule. The last box is empty.
- Pick the option that completes the grid from the 8 choices, then Confirm.
- 15 questions that get harder or easier as you answer. About 10 minutes, no time limit.
Which option completes the last box?
Your estimated score
An estimated score on Toolida’s practice scale. It is not a certified IQ score and does not replace an assessment by a psychologist.
The short answer
A 15-question logical reasoning test: each question is a 3 by 3 grid with the last box missing, and you pick what completes it from 8 options. Questions get harder when you are right and easier when you are wrong. You get an estimated score out of 10 on Toolida's practice scale, which is not a certified IQ score.
How it is calculated
The questions: the site generates each one from 16 rules across 6 levels: growing counts or sizes, rotation, "one of each" across every row and column, and overlapping lines. Puzzles do not repeat and cannot be memorized.
The score: you start at average. A right answer at a hard level lifts the estimate more, and a miss at an easy level lowers it more, with a 1-in-8 chance of guessing taken into account. After 15 questions the estimate becomes a score from 1 to 10, with 5.5 in the middle.
Why not an IQ number: an IQ needs your result compared with a large sample that represents the population. Our puzzles are new and not yet calibrated on such a sample, so we show a score on our own scale with its range, and never convert it to IQ.
Worked example
Emily solves the puzzles up to level 4 and misses levels 5 and 6:
- She starts at level 2, and each right answer moves her to a harder level.
- After 15 questions she has 8 right, and the hardest level she solved is 4 of 6.
- The test keeps you near the edge of your ability, so most people get about half right. What counts is how hard the solved puzzles were.
Estimated score 6.7 out of 10, likely range 6.1 to 7.2.
Quick reference table
| Rule | What changes | How to spot it |
|---|---|---|
| Count | One more shape in each box | Count the shapes across a row |
| Size | The shape grows or shrinks step by step | Compare the first and third box |
| Rotation | The arrow turns by a fixed angle | Follow the arrow from box to box |
| One of each | Each shape or fill appears once per row and column | Find what the last row is missing |
| Line overlays | The third box combines the lines of the first two, or drops the shared ones | Compare which lines the two boxes share |
Special cases and common mistakes
- New puzzles every time. The site builds each puzzle from its own rules, so there is no question bank to memorize or answer key to look up.
- No right-or-wrong feedback during the test, so it does not change how you approach the next question. Only the first practice question shows the answer.
- Your result is not sent anywhere. Scoring runs in your browser, and if you share your score it is only in the text of your own message.
- Take it when you are rested: tiredness and interruptions lower scores. There is no time limit, so do not rush.
Frequently asked questions
Does this test give me an IQ score?
No. It gives an estimated score out of 10 on Toolida’s practice scale. A certified IQ score comes from a calibrated test given by a psychologist, which compares you with a sample that represents the population.
How long does the IQ test take?
Usually about 10 minutes: 15 questions, with no time limit on any of them.
I only got about half right. Is that a bad score?
Not necessarily. The test gets harder when you are right and easier when you are wrong, so most people end with about half correct. Your score comes from how hard the puzzles you solved were, not how many you solved.
Why does my score come with a range?
Every short test has measurement error. The range shows where your true score most likely sits, which is more honest than a single number.
Can I take the test again?
Yes, and you get new puzzles each time. Retaking right away tends to raise the score a little, because you get used to the puzzles.
