About

Minesweeper is a logic puzzle genre in which players clear a grid of tiles without detonating hidden mines, using numeric clues about how many mines border each cell. PROXX is a web-based Minesweeper variant built by Google Chrome Labs to run on virtually any device with a browser, including feature phones. It's built with Preact, PostCSS, and Rollup, runs its core game logic inside a web worker via Comlink, and supports both WebGL and Canvas 2D rendering paths depending on whether animation is enabled.

How it differs from the original

Unlike typical desktop Minesweeper implementations, PROXX specifically targets universal browser compatibility, including low-powered feature phones, via a lightweight no-motion Canvas 2D rendering fallback alongside its animated WebGL mode.

Getting started

Play it directly in a browser at proxx.app; to build and run it locally, clone the repository and use the project's install, build, and serve commands.

Additional notes

Trivia

Debug URL flags let you bypass the ServiceWorker/IndexedDB cache, force no-animation mode, or start with mouse/keyboard focus enabled.
