Measure how youreason, not whatyou memorised.
Brightfold is a free reasoning test built on the six domains clinical IQ batteries use. Expect balance scales, codes, clock faces, hidden words, memory flashes and pattern puzzles, shuffled so no two items in a row feel alike.

Famous minds
Where do history’s great thinkers sit on the scale?
People have long tried to put a number on genius. Here are four popular retrospective guesses, for fun and perspective.
Albert Einstein
Physicist · 1879–1955≈ 160est.Isaac Newton
Mathematician · 1643–1727≈ 190est.Leonardo da Vinci
Polymath · 1452–1519≈ 180est.Stephen Hawking
Cosmologist · 1942–2018≈ 160est.

Your report
A cognitive blueprint, not just one number
Two people can land on the same score for very different reasons. Your report shows the shape behind it.
- Estimated score on the familiar mean-100 scale, placed on the bell curve.
- Six domain bars that show your strongest area and where there is room to grow.
- Pace and memory notes from your checkpoints and the opening-word recall.
- Every item explained, so you learn the rule behind each puzzle.

Why Brightfold
Built to be finished, and worth finishing
Short and varied
Twenty original items shuffled across six domains, so no two in a row feel alike.
Checkpoints, not stress
Four pace screens pause the clock and show how your profile is taking shape.
Explained answers
Each item comes with the reasoning behind it, so a miss teaches you something.
Private by design
No account and no tracking of your answers. Everything stays in your tab.
Reviews
Loved by test takers Placeholder
Proof-of-concept reviews. Replace with real, verified feedback before launch.
“Short enough to finish on a lunch break, and the puzzles actually varied. The checkpoint screens kept me going.”
“I liked that every answer came with an explanation. I finally understood number series.”
“The memory word at the end caught me out. Fun and a bit humbling. Certificate was a nice touch.”
“Clean, quick and no sign-up. Sent it to my whole family group chat.”
“The domain breakdown told me more than a single score would have.”
“Great on my phone. No pinching or scrolling sideways, which is rare for quizzes.”

What the test covers
Six domains, one composite score
Each domain maps to an index that the Wechsler and Raven’s family of tests also report. Every item was written for Brightfold.
Quantitative reasoning
4 itemsNumber and letter series, balance scales and short word problems with a tempting wrong answer.
seed:tree::egg:nest
Verbal reasoning
4 itemsAnalogies, letter codes, hidden words, anagrams, compound words and syllogisms.
Visual-spatial
3 itemsMental rotation, cube nets, folded paper, clock angles and compass turns.
Working memory
2 itemsDigits appear one at a time, then disappear. Type them back in order, or reversed.
Processing speed
3 itemsCount symbols against the clock, decode a symbol key and spot the one pair that differs.
Process
From first item to full breakdown
Step 1
Answer 20 items
The domains are shuffled together. Pick an answer and the next item slides in. Jump back to any item from the side rail, or use keys 1 to 6.
Step 2
Beat the clock
You have 16 minutes in total. Four short checkpoints show your pace and where your profile is taking shape, and the clock pauses while you read them.
Step 3
Read your breakdown
See an estimated score on the mean-100 scale, a bar for each domain and the reasoning behind every answer.
Scoring
Where scores fall on the curve
IQ scales are normed so the population mean is 100 and one standard deviation is 15 points. About two thirds of people land between 85 and 115.
- 130 +Very high≈ 2.3%
- 115 – 129Above average≈ 13.6%
- 85 – 114Average≈ 68.2%
- 70 – 84Below average≈ 13.6%
- under 70Low≈ 2.3%
Brightfold’s number is a practice estimate mapped onto this scale. It has not been normed on a sample population and is not a clinical assessment.
FAQ
Questions people ask first
Is this a real IQ test?
It uses the same item types as recognised tests, but a proper IQ score needs a test normed on thousands of people and given under controlled conditions. Treat your result as a practice estimate.
Does it cost anything?
No. There is no sign-up, no payment and no paywall on your result or your certificate. Your answers stay in your browser tab and are not sent anywhere.
How long does it take?
Sixteen minutes at most, for 20 items. The clock pauses on the checkpoint screens, so reading them never costs you time.
Why six domains?
Modern batteries such as the WAIS report separate indexes for verbal comprehension, fluid reasoning, visual-spatial ability, working memory and processing speed. Brightfold adds number series as a quantitative strand.
How is the score calculated?
Your share of correct answers is mapped onto a mean-100, standard-deviation-15 scale. Because the items have not been normed on a sample population, the number is a rough guide, not a clinical result.
Can I go back and change answers?
Yes, for every item except the memory and speed tasks, which you only see once. Those depend on a single exposure to be meaningful.
Can I use a calculator or paper?
Paper is fine. A calculator gives you an advantage on the series items, so your score will read higher than it should.
What happens if time runs out?
The test ends and unanswered items count as wrong. You still get the full breakdown and every explanation.
What does the certificate say?
It shows your name, estimated score, date and the practice-scale disclaimer. It is a keepsake for finishing the test, not an official credential. Print it or save it as a PDF from the results page.
Is my data stored?
No. Everything runs in your browser. Close the tab and your answers are gone, so save your certificate before you leave.
