Partial While the web UI and basic WebSocket room setup are straightforward, implementing complete, bug-free Mahjong rule engines, tile validation, scoring algorithms (fan/points), and competitive AI bots is notoriously intricate.
What it would actually take: The stack would combine a Node.js/Go backend with WebSockets and a canvas/WebGL frontend. The difficult bottleneck is encoding complex Mahjong game logic (Riichi, Hong Kong, or Mahjong Competition rules have hundreds of valid hand combinations, winning checks, and discards) alongside an efficient decision-tree or minimax/heuristic AI bot that doesn't hang or play illegitimately.
