What you get that other IQ sites do not give you

Most free IQ tests give you a number and a sales pitch. Here is what is different.

Per-domain subscores

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.

Real scores, not made up

Most free IQ tests invent their own scale. Yours follows the same standard your psychologist would use - so your percentile actually means something.

Live community percentile

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.

40 brain-training games

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.

Localized for 9 languages

English, Turkish, Spanish, Arabic, Russian, Chinese, German, Hindi, Indonesian. Take it in your language. Same accuracy, every time.

Live percentiles

Your score, ranked against everyone else who took the test

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.

  • Watch your rank update as more people finish the test
  • Each training game has its own ranking - see exactly where you stand on n-back, Stroop, mental rotation, every game
  • No login. No tracking. Anonymous score, real percentile.

How the score gets calibrated

Most "IQ tests" online are 10 questions and a paywall. Here is how this one is built.

Adaptive scoring

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.

Adaptive item weightingPer-question calibrationReal maximum-likelihood scoring

Lined up with the real scale

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.

Standard 100-mean scaleReal percentilesClinical-grade accuracy

Four cognitive domains

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.

User Reviews

What people say after they finish

Three honest comments from the inbox. No "this changed my life" filler.

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.

The good stuff to read after the test

Three short pieces that help you make sense of your number - what it means, how it was calculated, and whether you can train it up.

Quick answers

How long does the IQ test take?
Around 30 minutes for the full 60-question test. The quick test is 15-20 minutes. Both score on the same scale.
Is the test accurate?
Yes. The score is calibrated against the same scale a clinical psychologist would use, with adaptive scoring per item - so a 30-minute test reads as cleanly as a 2-hour clinical session.
Do I need to sign up?
No. No email, no account, no payment. The result page lives at a unique URL you can save, share, or close.
Can I retake the test?
Yes - as many times as you want. We recommend waiting a few days between attempts so practice effects do not inflate your score.
What does my score actually mean?
IQ 100 is average. IQ 130+ puts you in the top 2 percent. You also get four domain subscores so you can see whether the headline number came from balanced strength or one heavy lift.
Is the test free?
Completely free. The full IQ test, the brain training games, the result breakdown - all of it. We do not paywall the score.
What languages is the test in?
Nine: English, Turkish, Spanish, German, Russian, Chinese, Arabic, Hindi, Indonesian. Same items, same scoring across all of them.
How is this different from a clinical test?
Same scoring math (adaptive item-response scoring on a 100-mean, SD-15 scale), shorter format (30 minutes versus 2 hours), and you do not need an appointment or a 00 fee.
