Twenty questions on pattern spotting, logic and quick thinking, drawn at random from a bank of 120, plus a harder set in Hard mode. Many number and logic questions are generated fresh each time, so no two tests are quite the same. Every answer comes with a short explanation.
No calculator or search. Choose the single best answer; you can't go back once you confirm. Different questions show up each time you retake it.
A fun brain workout, not a clinical IQ test. A real IQ score needs a standardized, age-normed test given by a qualified professional, so this page shows a score out of 20 and a band, never an IQ number.
