Rule presets - Dutch League Rules

This rule preset represents modern Dutch variation of the game of Mah Jong, as determined in April 2002 by the Nederlandse Mah-Jongg Commissie. The rules are used on the tournaments in Amsterdam, Rotterdam, Hilversum, Rosmalen and Mechelen, Belgium. The winning hand must be worth at least 2 doubles, which can be achieved fairly easily as the rules give 1 double for easy patterns like Chow hand (no restrictions) and All Simples.

The rules encourage collecting of valuable hands since losers get paid for certain uncompleted hands without a requirement for a ready hand (e.g. for One suit with honors and One Suit Only), while getting 50% of the scoring all uncompleted but ready special hands (like Big Three Dragons or Seven pairs).

In addition to this classical version (with some typical American additions), the Dutch players also play tournaments with modern Japanese (Riichi) and Chinese Old Style (Hong Kong) rules.
