Web Design
IQ game
A bilingual reasoning test that runs entirely in the browser from a single HTML file — no accounts, no server, no tracking, and it works offline.
Context
A self-directed project, built to see how far a genuinely useful product could be taken with no framework, no build step and no dependencies. It is live on GitHub Pages and open to anyone.
The problem
Online reasoning tests almost all demand an account, run advertising against your results, and give you a number with nothing behind it. The interesting constraint was to remove all three at once, in two languages and two writing directions, and still keep the test worth taking.
What TAZ did
Thirty questions across five rising difficulty levels and a twenty-five minute timer, covering four reasoning families: numerical, verbal, logical and spatial. Every visual puzzle — matrices, figure sequences, folded shapes, dot patterns — is drawn live as SVG from a compact spec object, so there is not a single image file in the project and it stays crisp at any resolution. Scoring is difficulty-weighted and mapped through a deliberately non-linear curve to a standardised result, reported with a percentile and a per-category breakdown. Question and answer order shuffle each session, and progress is saved locally so an interrupted test can be resumed.
Where it stands
Live, shipped, and publicly inspectable. Persian right-to-left and English left-to-right, light and dark themes that follow the system, full keyboard navigation and reduced-motion support. The whole thing is one file with no framework, no build step and no dependencies — which is the actual engineering point, not a limitation. The result is framed on the site itself as an entertainment-grade estimate, not a clinical measure.
