The '''rules of Japanese Mahjong''' are not completely fixed and are overly complicated. The core mechanics are the same everywhere, so any comprehensive rules description is suitable for learning the game. Specific rulesets may then differ in finer details.
Japanese mahjong is quite complex with its many rules and special cases. This article is a brief and quick layout to the most basic rules of the game, just to get new players started.
