Frequently asked questions

What does this test measure and who is it for?

It measures numerical reasoning and spatial visualisation. It suits learners, curious readers and people preparing an exam on this subject. Expect logic puzzles and visual puzzles.

What formats and levels are available, and which should I choose?

Easy, Intermediate and Expert levels each offer Short version with 10 questions about 5 minutes, and Full version with 30 questions about 14 minutes, or about 15 minutes for Expert. Choose Short for a quick overview, Full for a more precise score.

How do timing, navigation and the Bookmark for review feature work?

Questions appear one at a time in a fixed order. You must pick an answer to proceed, but you may go back, change an answer, and flag a question with Bookmark for review. When the time remaining ends, the test ends by itself and unanswered questions count as wrong.

How can I prepare without seeing actual test questions?

Practise transitive reasoning, lateral thinking, numerical reasoning and spatial visualisation. Work methodically on rotations, grids, visual series and sequences. Do untimed puzzles to build speed, then add a time limit.

How is my score converted into a result band?

You get one point per correct answer. The band is Needs work below 40%, Intermediate from 40%, Advanced from 60%, and Expert from 80% only at Expert level; at other levels the top band is Advanced.

What is required to pass and what does the certificate include?

You need at least 6 correct answers out of 10 or 18 correct answers out of 30 depending on the version. A passed test earns a PDF certificate with first and last name, score, date, a certificate number and a QR code opening a verification page.

Can I retake the test, use the rankings and keep my result private?

Use Start again to retake as often as you like; the questions stay the same. The rankings, filtered by test, country and city, show only your best attempt, which is highest score then shortest time. They display first name, last name initial, country, city, score and time. Your result remains visible only to you.

About this test

Navigating the complexities of transitive and syllogistic reasoning

Logic is the silent framework that supports how we interpret the world, from the way we queue at a bus stop to how we process formal arguments. At its core, reasoning often involves transitive relationships, where you must determine the relative standing of individuals based on a series of linked comparisons.

Beyond simple rankings, the assessment delves into the world of formal logic through syllogisms. These problems ask you to determine what must be true based on specific premises, such as the relationships between different groups of objects. It tests your ability to avoid common fallacious leaps and stick strictly to the evidence provided. You will also encounter linguistic traps that hinge on specific phrasing, such as the distinction between a total number and a remaining quantity.

Mastering spatial rotations and mirror reflections

Our ability to visualise objects and their movements in space is a vital part of mental agility. The Brain Teasers and Logic Riddles test challenges you to perform mental rotations, such as predicting the new position of clock hands after they have moved through specific arcs. This skill is not just for reading analogue timepieces; it is fundamental to tasks like navigation, assembly, and understanding technical diagrams.

Visual sequences and grids further test this spatial awareness by requiring you to identify patterns in shapes and quantities across rows and columns. You might see circles, squares, or triangles that change according to their position, requiring a keen eye for detail and a systematic approach to problem-solving. These visual riddles mimic the way we process graphical data and architectural plans, where a single missing element can change the entire meaning of a structure.

Practical applications of numerical and proportional logic

Numerical reasoning in this assessment goes beyond simple arithmetic to explore how we handle money, time, and physical measurements in the United Kingdom. You will face challenges involving the smallest number of coins needed to reach a specific total, reflecting the everyday mental maths performed at a shop till. The test also covers proportional reasoning, such as calculating the true cost of items during a multi-buy promotion.

Temporal and rate-based logic also play a significant role. You will be asked to calculate how long a train takes to clear a tunnel or how many days it takes for a biological process to reach a certain threshold. These problems often involve setbacks or parallel work, requiring you to think critically about whether a rate is constant or if additional workers truly speed up a task.

Comparing the versions of Brain Teasers and Logic Riddles

To suit your current needs, two versions of the test are available. The short version contains 10 questions and takes 5 minutes, offering a quick burst of mental exercise that focuses on the core themes of transitive reasoning and spatial logic. If you prefer a more comprehensive evaluation, the full version offers 30 questions over 14 minutes, providing a deeper dive into financial logic, syllogisms, and complex rate problems.

Upon finishing, you will see your results immediately, allowing you to reflect on which areas of logic felt most intuitive and which required more deliberate thought. A high score suggests a strong ability to filter out distractions and focus on the underlying mechanics of a problem. Regardless of the outcome, engaging with these riddles serves as a valuable exercise in maintaining cognitive sharpness and improving your approach to the puzzles that appear in daily life.
