Rule presets - Italian Official

This rule preset represents modern Italian version of the game of Mah Jong, as presented by Federazione Italiana Mah-Jong. The rules combine classical European rules with some features from the modern Chinese and Japanese Mah Jong, e.g., the rule of voluntary ready (Riichi) is applied, though significantly differently than in Japanese Mah Jong, and several mid-difficult patterns have been added.
