The main differences of the RCR to other common Japanese Mahjong rulesets are:
* [[Kuitan]] nashi: Tanyao (all simples) was only awarded to closed hands only.
 
* [[Kuikae]] ari: Any discard is legal after calling chii or pon, even a tile which would also have completed the open meld.
* [[Kuitan]] nashi: The yaku Tanyao (all simples) may be awarded to closed hands only.

===Current (2016+)===
The most recent update to the EMA ruleset has made a number of changes, to resemble the standard set by the WRC rules. The remaining differences with the 2015 WRC ruleset are minimal
* Changes from previous EMA rules (2012): no more red fives; open tanyao ([[kuitan]]) allowed; renhou is now a strict mangan only; the maximum score is a single yakuman (Daisuushii no longer worth double); 11-han hands and above are all scored as sanbaiman; the timing rule was changed; no more swap-calling ([[kuikae]]); temporary furiten ends once the player can play their turn (draw or claim a tile); the 2-han restriction ([[ryanhan shibari]]) with 5 or more repeats is gone; no more abortive draws; no more nagashi mangan; rank bonus ([[uma]]) is now [+15P, +5P, -5P, -15P]; the chombo penalty in a tournament is now -20P (after rank bonus); penalties are generally less harsh.
* Differences with WRC rules (2015):
** Multiple winners are allowed
** ''4 han, 30 fu'' is not rounded to mangan payment
** Timing rules differ; EMA: pung takes predence over chow
** Riichi bets at game end go to the winner
