Gothic solitaire card game as an offline-first PWA — pure deterministic rules engine, React UI, headless balance simulator.
A digital implementation of Gravedigger, a gothic single-player solitaire game played with a standard 54-card deck — designed by @Pavornic , built for the web by me. The rules engine is a pure, deterministic, framework-free TypeScript state machine (fully tested with Vitest); the React UI only renders state and dispatches actions. It installs as a PWA, works offline after first load, supports seed-sharing links, and ships with a headless simulator used to balance-test thousands of games at a time.
