About this quiz
This quick IQ test is a twelve-puzzle workout for the parts of your brain that love a clean answer. You will continue number and letter sequences, solve a verbal analogy, untangle a logic statement, picture a painted cube and a folded rope, and face a handful of trick questions designed to punish the first answer that pops into your head. Every puzzle was written for this page and needs no special knowledge: no vocabulary tests, no trivia, no math beyond basic arithmetic.
The puzzles get harder as you go. The early ones reward pattern spotting. The middle ones are classic "slow down" traps, the kind psychologists use to show how quick intuition and careful reasoning can disagree. The last few ask you to rotate, fold and measure things in your imagination, which is where most people start counting on their fingers.
At the end you get your number of correct answers, a playful IQ-style estimate on the familiar 100-centered scale, and a full answer key with a one-line explanation for every puzzle, so you can see exactly where the trap was. Be honest with yourself: a real IQ assessment is a long, standardized test given under controlled conditions by a trained professional. This is not that. Treat the number as a fun benchmark to compare with friends, not as a verdict on your intelligence.
Tip: there is no timer, so read each question twice. Most wrong answers on this test come from reading too fast, not from thinking too little.

FAQ
Is this a real IQ test?
No. Real IQ tests are standardized on large groups, timed and administered by professionals. This is a quick puzzle quiz, and the IQ number is a playful mapping from your score, meant for fun comparisons only.
How is the IQ estimate calculated?
Every correct answer adds 5 points to a base of 85, plus a small random-looking wobble of up to 3 points that stays fixed for the same answers. Twelve out of twelve lands in the 140s.
Are the answers really correct?
Yes. Every puzzle has exactly one correct option and the answer key explains the reasoning in one line. If you disagree with one, re-read the question slowly: the trap is usually in the wording.
How long does it take?
Most people finish in three to five minutes. There is no timer, so take as long as you like.
Is it free and private?
It is completely free with no sign-up, and your answers never leave your device. The score is calculated in your browser.
Can I retake it?
Of course, but the puzzles are the same, so a second run measures your memory more than your reasoning. Send it to a friend instead and compare.
For entertainment only. This is a puzzle quiz, not a standardized or clinical intelligence test, and the IQ-style number is a just-for-fun estimate with no psychological or diagnostic meaning.
