- Zero dependencies — nothing to install, nothing to audit, nothing to break.
- No build step — the files in this repository are the shipped artifact. Clone and double-click.
- Genuinely vanilla — plain HTML, CSS and JavaScript. No framework, no bundler, no transpiler.
- Bilingual UI — every game switches between English and 简体中文 via one shared 2 KB i18n module.
- Plays anywhere — desktop keyboard, mouse, and touch/swipe on phones; each game fills the screen and scales.
- Tested — a smoke suite loads every game in a stub DOM, and rule-heavy games carry their own logic suite that proves the rules actually work, not merely that the page loads.
- AI-written, end to end — roughly 9,000 lines of HTML, CSS and JavaScript, none of it typed by a human. See How this was made.
Every line of code in this repository was written by an AI agent. None of it was typed by hand.
The human half of the loop was: describe a game, look at the result, say what is wrong, ask for the next one. The agent half was: write the HTML, CSS and JavaScript, write the tests, run them, fix what failed, and commit.
prompt -> generate -> run tests -> inspect in a browser -> fix -> publish
That is also why the two constraints below are non-negotiable. An AI-written codebase that quietly pulled in frameworks and build tooling would be impossible to review; the whole value here is that you can open any file and read it top to bottom.
- One folder per game plus a landing page, well over ten thousand lines of plain HTML, CSS and JavaScript, zero dependencies, zero build steps.
- The tests were written the same way, and they are what keeps the pile honest: a smoke suite loads every game, and rule-heavy games get logic suites that prove a game works, not merely that it loads.
- The bugs are in the history too — a down arrow in Tetris whose held state was never recorded, Sokoban levels whose crates could not be pushed, a start screen the player could not reach. Finding and fixing those in the open is part of the point.
If you are curious what an AI can build unaided, this is a reasonably honest sample. If you want to see where it still needed a human, read the commit log.
- Plain
HTML/CSS/JavaScript, rendered with DOM elements and<canvas>where it pays off. - Shared i18n helper:
assets/i18n.js— a ~2 KB, zero-dependency language switcher persisted inlocalStorage. - Served straight from the repository with GitHub Pages (
.nojekyllkeeps the pipeline out of the way).

- Copy an existing
<game>-game/folder and rename it. - Replace the game logic inside
index.html. - Add an entry to the card grid in the root
index.html, to its JSON-LDItemList, to the table above, and tositemap.xml. - Run
node tools/smoke.js— it discovers every*-game/folder automatically and fails on any uncaught error. - Open a pull request. See CONTRIBUTING.md.
Bug reports, new games, translations and visual polish are all welcome. Read CONTRIBUTING.md first — it is short.
