Online logic test

Logic test: 20 matrices in 15 minutes

Also known as: Logic test, logical reasoning test, 20 matrices test, abstract reasoning test with shapes

Twenty 3 × 3 grids, each with one empty cell. In each one you find the rule and choose the missing figure from six options. Tasks go from easy to hard, and you have 15 minutes for the whole test. The result is the number of correct answers and a rating on the trainer’s scale. You get your result for free after entering your email: we show it on screen and send it to your inbox.

What it trains

What the matrix test checks

The test checks how you find patterns in shapes. Across the grid, the shape, color, number and size of the figures change, and sometimes so do small marks in the corners. You need to work out the rule each feature follows across rows and columns and apply it to the empty cell.

This isn’t a clinical test and it doesn’t measure IQ. The result shows how many tasks you solved in this trainer and compares it with our scale. Once you sign up, your attempts are saved, so you can see how your result changes from one attempt to the next.

Finding the rule

Notice exactly what changes from cell to cell.

Several rules at once

In hard tasks, shape, color, number and marks change by different rules.

Adding and subtracting figures

In some tasks the third cell of a row comes from the first two.

Ruling out options

Wrong answers look like the right one and break one or more rules.

Rules

How to play

Start
Press “Start”. A 15-minute timer begins, and the first of 20 tasks appears.
The grid
Look at the 3 × 3 grid. The bottom-right cell is empty. Compare the cells across rows and down columns.
Rules
Work out how each feature changes: shape, color, number of figures, size, marks in the corners. The rules vary: a feature depends on the row or the column, each value appears once in every row and column, values alternate, add up or subtract.
Answer
Choose one of six options. Your answer is recorded right away and the test moves on to the next task. We don’t show whether it was right along the way. You can skip a task.
Results
After 20 tasks, or when the timer runs out, you’ll see the number of correct answers, your results by difficulty level, the time spent, the number of skips and a rating on the trainer’s scale.

Method

What the test is based on and how to read the result

The format is close to J. C. Raven’s matrix tests (1936): a grid of figures with a gap, plus answer options. Here the tasks are created by a generator following our own rules, and within the test’s rule system exactly one option out of six fits the conditions: the program checks this. It’s a trainer built on the method’s format, not the original Raven test.

The scale by number of correct answers: 17–20 is very high, 13–16 high, 9–12 average, 5–8 below average, 4 or fewer low. This is the trainer’s own guide, not a diagnosis and not an IQ score. Your result is affected by fatigue, noise around you and how used you are to tasks like these. To look for patterns in numbers, try Number Sequences; in patterns, try Missing Piece; and the Patterns exercise lets you practice without the test’s time limit. Mini Sudoku and Scales make a good warm-up.

1–5One ruleOne feature changes: shape, color or number, and in tasks 4–5 also size. Easy tasks

6–10Two rulesTwo features change independently. Values alternate or run diagonally

11–15Two or three rulesThree features at once (tasks 11, 14, 15) or two rules, one of which is adding and subtracting the number of figures (12) or marks (13). Alternation appears

16–20The hardestThree or four rules at the same time: marks add up and subtract, the number of figures adds up or subtracts

Who it’s for

Which ages

Adults

A good fit if you want a timed logic check: 20 tasks, 15 minutes and a scale for reference.

Kids

Not in the “Kids” collection. For schoolchildren the trainer has a shorter version: 12 matrices in 10 minutes, using only the first 10 difficulty levels.

60+

Not in the “60+” collection. The test is designed for 15 minutes with no breaks. If you’d rather practice at a calmer pace, start with the Patterns exercise.

Questions

Frequently asked questions

Is this an IQ test or a diagnosis?

No. It’s a rating of logical reasoning on our own scale, not an IQ test and not a diagnosis. The result shows how many tasks you solved in this trainer and depends on fatigue, attention and experience.

How is the test different from the Patterns exercise?

The exercise runs for two minutes, the difficulty adapts to you, and after a mistake you see the right answer. The test has 20 tasks of increasing difficulty, 15 minutes in total, no hints along the way and a final rating on the scale.

Can I skip tasks and come back to them?

You can skip, but you can’t go back to a skipped task: answers are recorded right away. A skip doesn’t cost points, but it doesn’t earn any either. If time runs out, unanswered tasks count as skipped.

Does every task have exactly one correct answer?

Within the test’s rule system, yes. A generator creates the tasks, and the program checks that only one of the six options fits all the task’s rules. Wrong options differ from the right one in one to three features, and some of them look more like the neighboring cells than the right answer does, so it’s hard to guess by visual similarity. Luck still plays a part, though: a random pick out of six is right one time in six.

Do I need to sign up?

You can start without signing up. Play without an account is limited to 10 minutes a day, and the test takes up to 15, so it’s best to sign up to complete it in full and save your results.
