The IQ test that shows its work
Five kinds of thinking, fifteen minutes, one score you can actually interpret. No sign-up, no email, no paywall, no results held hostage.
What you get at the end
A score with a range
Not one flattering number. You get the interval your answers actually support, so you know how much to trust it.
A profile, not a total
All five areas scored separately. The shape is usually more interesting than the overall height.
A link that just works
Your whole result travels inside its own URL. Share it, bookmark it, come back to it — there is no account and no server holding it.
What you’ll do
Five rounds, one after another, each with its own clock. You can stop between rounds but not inside one.
Fluid reasoning
8 items · up to 8 minComplete the pattern. Each grid follows a rule — find it, then pick the piece that belongs in the empty cell.
Quantitative reasoning
6 items · up to 5 minEach sequence follows a rule. Work out the next number and type it in.
Verbal reasoning
6 items · up to 4 minWork out how the first pair relates, then complete the second pair the same way.
Working memory
10 items · up to 6 minWatch the digits, then type them back in reverse order.
Processing speed
60 secondsMatch each symbol to its digit using the key. As many as you can in 60 seconds.
Why you can trust the number
Most free IQ tests either hide their method or don’t have one. This one publishes the whole thing: how each round is scored, how the scores combine, where the reference figures come from, and — the part nobody else writes down — exactly which parts are estimates rather than measurements.
It also refuses to flatter you. Scores are capped at the range a fifteen-minute test can honestly resolve, and every result is shown with its margin of error rather than as a single confident digit.
