What is a pattern recognition test?

A pattern recognition test measures how well you can spot a hidden rule and use it to predict what comes next. Each puzzle shows you part of a pattern, such as a series of numbers or a grid of shapes, and asks you to choose the piece that completes it.

Psychologists call the skill behind these puzzles fluid reasoning: solving problems you have never seen before, without relying on things you have learnt. It is why pattern puzzles appear in almost every intelligence test, from Raven's Progressive Matrices to the matrix reasoning section of the Wechsler scales.

How to test your pattern recognition skills

The simplest way is to work through a set of pattern puzzles that get steadily harder, then see where you start to make mistakes. For a fair result:

1. Use a mix of puzzle types. Number series, letter series, shape sequences and matrices each test a slightly different side of pattern recognition. A test with only one type tells you about that type alone.
2. Take it in one sitting, somewhere quiet. Interruptions break your chain of thought on the longer puzzles.
3. Don't look anything up. The point is to see how you reason on your own.
4. Count your first attempt. You will almost always score higher the second time, because you have already seen the puzzles.
5. Read the explanations afterwards. Seeing the rule you missed is the quickest way to improve.

The test above follows all of these. It covers five puzzle types, gets harder as it goes and explains every answer at the end.

The five types of question in this test

Number series

A row of numbers follows a rule, such as adding the same amount, doubling, or adding a gap that itself grows. Tip: write down the difference between each pair of numbers. The pattern is often hiding in the gaps rather than the numbers.

Letter series

Letters move through the alphabet by a fixed or changing step. Tip: convert letters to their positions (A = 1, B = 2 and so on). A letter puzzle then becomes a number puzzle.

Shape sequences

A shape changes step by step: it turns, gains sides, moves or changes colour. Tip: check one feature at a time. The hardest sequences change two features at once.

Odd one out

Three pictures share a rule and one breaks it. Tip: before choosing, make sure the rule you have found fits the other three exactly. If two different rules seem to work, look for a more specific one.

Matrices

A 3 × 3 grid with one square missing, like the puzzles in Raven's Progressive Matrices. Tip: check the rows and the columns separately. Common rules include each row containing one of every shape, or the first two squares adding up to the third.

Pattern recognition test questions with answers

Here are three example questions in the style of the test, with the reasoning behind each answer.

These examples are separate from the 20 test questions, so trying them first won't give away any answers.

Is this a pattern recognition IQ test?

Not quite, and it is worth being clear about the difference. This test uses the same kinds of puzzle that appear in IQ tests, but it has not been standardised against a representative sample of the population, so your result is a score out of 20 rather than an IQ. Our guide to how IQ is calculated explains why that comparison group matters.

For an estimated IQ score across pattern, number, logical and applied reasoning, take the free IQScore cognitive assessment. It uses different questions from this test, so practising here won't inflate that result.

Is high IQ just pattern recognition?

Pattern recognition is a big part of IQ, but it isn't the whole of it. Raven's Progressive Matrices, a test made entirely of visual pattern puzzles, is regarded as one of the best single measures of general reasoning ability. A classic 1990 analysis by Carpenter, Just and Shell found that what separates high and low scorers on Raven's is the ability to work out abstract rules and keep several of them in mind at once, which draws on working memory as well as pure pattern spotting.

Full IQ tests measure more than that. The Wechsler scales, for example, also include verbal comprehension, working memory and processing speed. Someone can be excellent at pattern puzzles and average on vocabulary, or the other way round. So a high score here is a good sign for one important part of intelligence, not a measure of all of it. See what counts as a good IQ score for how the full scale works.

Pattern recognition and autism

Pattern recognition is often described as a strength in autism, and research gives that idea some support. In a well-known 2007 study, Dawson and colleagues tested 38 autistic children on Raven's Progressive Matrices and on the Wechsler scales. On average, the children scored 30 percentile points higher on Raven's, and some scored more than 70 points higher, while non-autistic children showed no such gap.

The researchers' point was that heavily verbal tests can underestimate autistic reasoning ability, not that every autistic person is a pattern-recognition expert. Later research suggests the size of the gap varies from one group to another, and autistic people differ from one another as much as anyone else. An online pattern recognition test can't identify or rule out autism. If you are wondering about autism for yourself or your child, a qualified professional is the right person to speak to.

Are people with ADHD good at pattern recognition?

You will often read online that people with ADHD have exceptional pattern recognition. Many people with ADHD describe noticing connections others miss, and that experience is real, but laboratory studies do not show an across-the-board advantage.

On matrix-style reasoning puzzles, groups with ADHD tend to score slightly lower on average than groups without it. Researchers link this mainly to demands on attention and working memory rather than to reasoning itself. A 2026 eye-tracking study found that participants with ADHD tackled Raven's puzzles with the same problem-solving strategy as everyone else, even though their accuracy was lower on average. Averages also hide a huge range: plenty of people with ADHD score very highly. As with autism, this test can't tell you anything about ADHD.

Is pattern recognition a rare skill?

No. Everyone uses pattern recognition constantly: reading, recognising faces, understanding speech and learning a route all depend on it. What varies is how well people handle abstract patterns, like the puzzles in this test.

That ability is spread across the population like other reasoning skills, with most people in the middle and fewer at the extremes. Being able to solve the hardest multi-rule puzzles quickly and reliably is uncommon, in the same way that a very high IQ is uncommon. Our guide to what an IQ of 130 means shows how rare the top end really is.

How to improve your pattern recognition

• Practise a variety of puzzles. Matrices, number series and logic puzzles each build a different habit. Practice improves your score on familiar puzzle types more than it raises general intelligence, but the habits it builds are genuinely useful.
• Learn the common rules. Most puzzles use a small set of rules: constant steps, growing steps, doubling, rotation, alternation and addition. Once you know them, you will spot them faster.
• Say the rule out loud. Putting a rule into words, such as "it turns 90 degrees and swaps colour", helps you check it against every part of the puzzle.
• Train your working memory. Harder puzzles need you to hold several rules at once. Games like the Number Memory Test and Visual Memory Test exercise exactly that.
• Review your mistakes. Go through the explanations after each attempt. The rule you missed today is the one you will spot next time.
