How is the estimated IQ calculated?

Correct answers are weighted by difficulty (1, 1.3 and 1.7 points for one-, two- and three-star items), and the weighted score is mapped onto a scale with a mean of 100 and a standard deviation of 15. The result is capped between 70 and 145.

How long does the test take?

There is a 60-minute time limit for 120 questions. You can choose to play without a time limit, but the estimated IQ is then capped at 130 because the norms assume timed conditions.

Is this an official IQ test?

No. All items were written for this site and the score is a rough estimate for fun and brain training. A real IQ assessment must be given by a qualified psychologist using a standardized test.

IQ Test — 120 Questions

Matrices, number series, verbal analogies and math & logic. 60-minute time limit — no calculator.

Before you start

Questions go from easy to hard. If you get stuck, skip and come back later.
When time runs out, the test is scored automatically. Progress is saved on this device, so you can leave and resume.
Pen and paper are fine, but please don’t use a calculator or search engine.

Play without a time limit (the estimated IQ is based on timed conditions, so it may come out higher)

How this IQ test works

The test has 120 questions in four sections: 36 matrix puzzles (find the missing picture from the row and column rules), 36 number series (find the next number), 24 verbal analogies and odd-one-out items, and 24 math & logic problems. Items are sorted from one-star to three-star difficulty, with the section types mixed together.

Scoring

Each correct answer is weighted by difficulty — 1 point for ★, 1.3 for ★★ and 1.7 for ★★★. Your weighted percentage is converted to an estimated IQ on a scale with a mean of 100 and a standard deviation of 15 (shown between 70 and 145), and then to a percentile. If you turn off the time limit, the estimate is capped at 130. The section bars show where your reasoning is strongest: matrices measure visual pattern reasoning, number series measure numerical rule-finding, verbal items measure how well you see relationships between concepts, and math & logic measure problem solving.

Disclaimer

All questions were written for Honglife; none are taken from real IQ tests such as the Wechsler scales or Raven’s Progressive Matrices. The estimated IQ is not standardized on a large sample — it is a rough estimate for entertainment and brain training. For a real assessment, see a licensed psychologist. When you finish, only your anonymous score, section scores and time used are sent to Google Analytics (no name or contact details) so the scoring can be recalibrated as more people take the test.
