Mahjong: A Visual Guide | Hacker News

A Hacker News post on a visual Mahjong guide sparked discussion about how to teach the game to beginners.

Commenters noted that Mahjong is widely played across Asia, but the rules vary significantly by region and city.

The thread highlighted basic scoring, local variants in places like Changsha, Shenzhen, and Hong Kong, and the difficulty of learning from static reference material alone.

Many pointed to interactive explainers as a better way to understand complex rule systems like Mahjong.
