Three short memory scenes, then 32 puzzles that adapt to you: number sequences and rules, shape patterns and matrices, logic and ordering puzzles written in made-up words, mirrored or turned patterns, and a few timed riddles. The puzzles are generated fresh from a random seed each attempt, so there is no answer key to memorize (the riddles come from a fixed bank of 25). The result is an indicative IQ-style estimate with a likely range and a score for each area; the scoring allows for the one-in-four chance of a lucky guess. It has never been normed on a representative sample and is not a clinical IQ test. Speed does not change the score except that a riddle which runs out of its 30 seconds counts as missed, and the made-up-word logic needs basic English.

Runs in your browser: nothing to install
scripts/test-cognitive-assessment.ts (108 checks) re-solves every generated puzzle independently, replays sessions from their seed, and checks the scoring against hand-computed and brute-force values. In a simulation of 400 test-takers with known ability the estimate correlated 0.88 with the truth, was unbiased, and the reported range contained the true value for 96% of them. That holds under the test's own model only; it says nothing about real people, because the scale has never been normed.
