How this reasoning test works

This test contains 20 puzzles that focus on three kinds of reasoning. Pattern recognition puzzles ask you to find the rule that connects a set of shapes or symbols. Number sequence puzzles ask you to spot how numbers change from one step to the next, such as adding, multiplying, or alternating. Logic puzzles ask you to draw a correct conclusion from a few given facts. Together, these give a small sample of abstract reasoning, which is one of the areas that traditional IQ tests also look at.

When you finish, we count how many puzzles you answered correctly. That raw score is then mapped to an estimated score on the familiar IQ-style scale, where 100 is set as the average and 15 points is one standard deviation. The mapping is a simple approximation, not a statistical norm table. Because 20 puzzles cannot separate very high or very low results reliably, the estimate is capped at both ends of the range. Your answers are scored in your browser, and the result appears right away.

This is not a real IQ test, and the number should not be used for any formal purpose. Proper IQ tests are standardized on large, carefully selected groups of people who take the test under supervised conditions. This test has no such norms. Your result can also change with sleep, mood, stress, distractions, how familiar you are with puzzles, and how much time you take. Think of the estimate as a fun snapshot of one sitting, not a measurement of your ability.

If you need an accurate assessment, for example for school support, a work accommodation, or a medical question, contact a licensed psychologist. A professional assessment uses established, well-researched tests, takes place in a controlled setting, and usually lasts one to two hours or more. The psychologist also interprets the results alongside your history and other information, which an online quiz cannot do. Be careful with websites that sell official-looking certificates, since an online quiz cannot provide a valid IQ score.

If you enjoy these puzzles and want to get better at them, practice is simple. Try a few number sequences, logic grids, or pattern puzzles each day. When you miss one, go back and name the rule you overlooked. Work slowly at first, then add a time limit once you feel confident. Practice will make you faster with this kind of puzzle, but keep in mind that it mostly builds familiarity with the format. Reading, learning new skills, sleep, and exercise help your thinking more broadly.
