About this site
A free IQ-style test with transparent score context. Plus brain-training games, specialized tests, community puzzle challenges, and an open intelligence research library. Built by people who got tired of paywalled "your IQ score is ready - pay to see it."
A free platform for measuring, training, and exploring intelligence.
Most online IQ tests are 10 questions, a vague score, and a paywall. We wanted a transparent educational IQ-style test that stays free.
The site started as a single 60-question IQ test in English. Over time we added eight more languages, the four-domain breakdown, brain-training games to practice the abilities the test measures, specialized tests, community puzzle questions, and an open research library covering intelligence science.
No paywall, ever
The full IQ test, your detailed result page, and all 40 training games are free. No upsell at the end.
Honest scoring
IQ 100 means average. IQ 130 means top 2 percent. Standard 100-mean IQ-style scale, not a number we made up.
Anonymous by design
No signup, no email. Your result page lives at a unique URL - bookmark it, share it, or close the tab.
What this site does well
Six things we care about, six things we got right.
IQ-style score interpretation
Adaptive item-response scoring on a standard 100-mean IQ-style scale, so the educational estimate is consistent across runs.
Four domain subscores
Verbal, spatial, logical, working memory - scored separately. The pattern often matters more than the headline number.
Anonymous, no signup
No account, no email, no tracking past basic analytics you can opt out of. The result page is yours.
Live percentile rankings
Every result includes where you sit against other recent players, not just a static research curve from decades ago.
Available in 9 languages
English, Turkish, Spanish, German, Russian, Chinese, Arabic, Hindi, Indonesian. Same items, same scoring across all of them.
40 brain-training games
After the test, train the parts that need work. N-back, Stroop, mental rotation, reaction time, and 36 more.
What is actually live on this site
Honest counts, not marketing claims.
From "I want to know my IQ" to a real result, in four steps.
No tricks, no hidden steps, no "your score is ready - just sign up." Pick your length, answer the questions, read the breakdown.
Pick a test variant
Full test (60 questions, 30 minutes) for the cleanest score, quick test (20 questions, 15 minutes) if you are short on time, or 10 sample items just to see what the format looks like.
Answer at your own pace
Each question has a soft 2-minute cap. You can skip and come back. The questions get harder as you go - that is how the score gets calibrated.
See your result, breakdown, and percentile
Overall IQ score, percentile against research norms, and how you scored in each of the four cognitive domains. All on one page, no email gate.
Train the weaker parts
Each domain on the result page links to training games that target that ability. Working memory low? Try n-back. Spatial weak? Mental rotation. Five-minute sessions, live percentile rankings.
Built on standard IQ-style reasoning categories
No black-box scoring. The full method is published on the methodology page if you want the details.
Adaptive item-response scoring
Each question has a calibrated difficulty. Harder ones you solve can carry more weight than easier ones, which helps produce a more stable educational estimate.
Standard 100-mean scale
Your educational score uses the standard 100-mean IQ-style scale. IQ 100 is average; the standard deviation is 15. So a 130 reads as top 2 percent on that scale, not an internal "platinum tier."
Four cognitive domains
Verbal reasoning, spatial reasoning, logical reasoning, and working memory - each scored independently. Most modern IQ instruments split the score this way for a reason.
Live percentile rankings
Beyond the static research norms, each result also includes where you sit against the live player population - so the comparison stays current as the player base grows.

Thirty minutes. No email. No paywall. The result page is yours to keep.
