3D Mahjong, Built in CSS

What is 3D Mahjong, Built in CSS?

3D Mahjong, Built in CSS is a free, open-source implementation of Mahjong Solitaire called VoxJong. The game demonstrates VoxCSS, a CSS-based voxel engine that renders 3D graphics directly in the browser using HTML and CSS transforms rather than WebGL or Canvas. Players can interact with traditional Mahjong tiles displayed in a three-dimensional environment. The underlying VoxCSS framework creates 3D grid-based structures by stacking DOM elements and applying CSS transforms to generate cuboid shapes. It supports colors, textures, user interactions, and culling optimization. The engine is framework-agnostic and works with Vue, React, Svelte, or vanilla JavaScript. VoxJong serves as both a playable game and a practical example of what's possible when building 3D experiences with web standards. The project is fully open-source and available on GitHub, making it suitable for developers interested in CSS-based 3D rendering techniques, game developers exploring alternative rendering approaches, or casual players looking for a free Mahjong game. The implementation highlights how modern CSS capabilities can handle complex visual effects without requiring specialized graphics libraries.
