14 classic browser games in one installable PWA — no install, no login, no build step, playable offline.

oriz.games is a collection of 14 classic games built with pure HTML, CSS, and JavaScript — a single static site with zero build step. It installs as a PWA, works offline via a service worker, and keeps your high scores in localStorage.

This is a browser games collection — pure client-side HTML/CSS/JS. (Any repository description mentioning a "Python pygame library" is a stale placeholder; the code here is the browser collection.)

Repo structure

index.html        # hub / landing
style.css         # shared styles
sw.js             # service worker (offline cache)
manifest.json     # PWA manifest (installable)
games/*.html      # one self-contained page per game
CNAME             # games.oriz.in

Configuration

No environment variables and no secrets — it's a fully static site.

Local dev

npx serve .
# or
python -m http.server 8080

Then open the served URL. There's no build step; you can also just open index.html directly for most games (a served origin is recommended so the service worker and PWA features work).
