Rule presets

Chinese Transitional

This rule preset represents a kind of a mixture of the Chinese classical, Old Style (Hong Kong) and New Style Mah Jong. These three styles are normally described separately in rule books, but they actually existed side by side during the 1930's, and were frequently intermingled. Though these kinds of rules are seldom used in modern Mah Jong, they illustrate well how the classical game was eventually developed into the Old Style and New Style

The rules use the classical scoring system, where the basic sets, winning and certain special ways of going out earn point scores. In addition, numerous New Style patterns the scoring of which is specified in doubles are acknowledged. Applying the classical linear doubling would easily result in extremely high scores, and accordingly these rules are the first to apply the concept of regulated doubles, a feature that is so typical to modern Asian Mah Jong.

Otherwise the rules are typically Old Style: the losers do not settle the scores and East winner is not paid double instead, if the winner goes out self-drawn, all pay double, and if he goes out on a discard, the discarder pays double and the other losers normally.
