Most free IQ tests give you a number and a sales pitch. Here is what is different.
Most sites give a single number. We split your score into verbal, spatial, logical, and working-memory components, so you can see whether the number came from balanced strength or one heavy lift.
Most free IQ tests invent their own scale. Yours follows the same standard your psychologist would use - so your percentile actually means something.
Beyond static research norms, you also see where you sit against other people who took the test recently - the comparison stays fresh as the player base grows.
After the test, train the weak domains. N-back, Stroop, dual N-back, mental rotation, reaction time, plus 35 others. Each game has a live percentile of its own.
English, Turkish, Spanish, Arabic, Russian, Chinese, German, Hindi, Indonesian. Take it in your language. Same accuracy, every time.
No signup required to see your full result. The page lives at a unique URL you can save, share, or close - your choice.

Most IQ tests dump you on a curve from a 1985 study. This one shows you both - where you stand on the science, AND where you stand against thousands of real people taking it right now. Live, current, real.
Most "IQ tests" online are 10 questions and a paywall. Here is how this one is built.
The harder the question you nail, the more it counts. The score adapts to you item by item - so a 30-minute test reads as accurately as a 2-hour clinical one.
IQ 100 means average. IQ 130 means top 2%. Your number maps to the same scale every clinical IQ test uses - not a fake number we invented to flatter you.
Verbal, spatial, logical, working memory - scored separately. So you do not just see "your IQ is 118." You see exactly which kind of thinking is your strength.
The full methodology is published on this site. We did not invent a scale, we did not weight things by feel, we did not paywall the breakdown.

Three honest comments from the inbox. No "this changed my life" filler.
Took the test out of curiosity, ended up reading the methodology page twice. The domain breakdown explained why I always score lower on verbal tasks. Useful self-knowledge.
I have given this to several students who asked about IQ tests. The 30-minute version is the right length for them, and the percentile context helps them not over-interpret a single number.
The brain training section is what hooked me. Played n-back daily for two weeks, watched my percentile climb from 40th to 70th. The feedback loop is honest, not gamified.
Take the test and form your own opinion.
