About this test
This is a reasoning challenge for educational and entertainment purposes: it measures how many of ten exercises in logic, number series, deduction and reflective thinking you get right. Several questions are designed so the intuitive answer is the wrong one — that's the fun part. A real IQ can only be measured with standardized tests administered by a professional, so take the result for what it is: a mental game, not a label.
Frequently asked questions
Does this measure my real IQ?
No. A real IQ is measured with standardized tests (such as WAIS or Raven) administered and interpreted by a professional. This test is a reasoning challenge for educational and entertainment purposes.
Why are some obvious answers wrong?
Several exercises test reflective thinking: they're designed so the first answer that comes to mind is the wrong one. Catching that impulse and checking before answering is precisely part of what's being tested.
Can I retake it?
Yes, but keep in mind that on a retake you already know the answers, so the result stops being representative.
