XOX — Ultimate

Tic-tac-toe in Glyph: a classic 3×3 mode and an Ultimate 9×9 mode (nine boards inside nine boards), with an AI opponent that thinks in a web worker. The engine and search are written in Glyph and compiled to browser-loadable ES modules.

Run

npm install
npm start

Then open http://localhost:8787.

The first npm start also compiles the Glyph engine to assets/engine/ (via tools/build-web.mjs); without that step the page loads but the board stays empty because the browser modules 404. Later starts skip the build if assets/engine/ already exists.

Rebuild the browser engine

After editing the engine source (src/xox.glyph, src/ultimate.glyph, src/ultimate_ai.glyph), regenerate the browser modules:

npm run build:web

The server reads assets from disk on every request, so a reload in the browser picks the new build up — no restart needed.

CLI mode

The same engine also plays in the terminal:

npx glyph run . cli

Anything after cli is passed through to the CLI game.

Layout

• src/ — Glyph sources: game rules, AI search, web server, CLI
• assets/ — the static web app (index.html, app.js, styles, worker)
• assets/engine/ — generated browser build of the Glyph engine (gitignored)
• tools/build-web.mjs — Glyph → browser ES-module pipeline, with audit and smoke test
• specs/ — specifications
