These rules are described in detail in Mahjong Competition Rules (The World Mahjong Organization, 2006), also known as 'The Green Book'. They were first used in an official tournament at the World Championship 2002 in Japan. The first major European tournament played by these rules was the 1st OEMC in Nijmegen, the Netherlands, during wich event EMA was founded.


Besides the MCR-Rulebook the 'Tournament Regulations' and the 'Referee Manual' are the official guidelines for MERS tournaments as from January 1st, 2009.

The first edition of the EMA riichi rules was established in preparation of the First European Riichi
Championship in 2008 in Hannover, Germany. The rules were based on the way riichi had been played by
pretty much the same rules independently in Netherlands and Denmark for years. The rules were revised in
2012 to be closer to current Japanese riichi rules, though still with some variants retained.

In preparation of the event of the first World Riichi Championship in Paris, France, in 2014, the World Riichi
Championship rules were compiled by Sylvain Malbec in collaboration with partners worldwide, notably
the Japan Mahjong Professional League. After the event the WRC rules were slightly revised in 2015, and it
was obvious to revise the EMA riichi rules in light of the WRC rules. The latest revision came into effect April 1, 2016.
