Application of the [[Yaku_variations#Multiple_yakuman|multiple yakuman may vary]], as some rules do not allow multiple yakuman in terms of [[scoring]].  This is largely due to the extremely high value applied by multiple yakuman.  In this case, even if the hand is composed of multiple yakuman, the score payout may be capped.
Application of the [[Yaku_variations#Multiple_yakuman|multiple yakuman may vary]], as some rules do not allow multiple yakuman in terms of [[scoring]].  This is largely due to the extremely high value applied by multiple yakuman.  In this case, even if the hand is composed of multiple yakuman, the score payout may be capped.


* '''Yakuman as maximum score:''' Many professional organizations in Japan limit all payouts to a single yakuman, that being 32,000 points to a nondealer or 48,000 points to the dealer.
===Single Yakuman Cap===
* '''Single yakuman score per accumulated yakuman:''' On [[Tenhou.net]], [[suuankou tanki]], [[daisuushi]], and the multiple wait versions of [[kokushi musou]] and [[chuuren poutou]] are all counted as scoring 1 yakuman. Cumulative yakuman, such as the examples below, are counted as 2 or more yakuman.
 
* '''Full scoring:''' The common rules normally recognize that all yakuman are cumulative (except kazoe yakuman), and that the harder yakuman are worth double when counting.
Many professional organizations in Japan limit all payouts to a single yakuman, being 32,000 point for nondealer and 48,000 points for the [[oya|dealer]]. This means that there are no double yakuman, and yakuman are not cumulative.
 
===Cumulative Single Yakuman===
 
Some groups, most notably [[Tenhou.net]], do not award double yakuman for any specific hand, but will award double yakuman if two different yakuman are completed in the same hand---most commonly [[tsuu iisou]] alongside either [[shousuushi]] or [[daisangen]].
 
===Full Scoring===
 
In many rulesets, not only are yakuman cumulative, but certain particularly rare and difficult hands are worth double the score value of a normal yakuman. For the most part, these are based on the [[machi|wait patterns]] used to win the hand:
 
* [[daisuushi]] is more difficult to complete than the lesser hand [[shousuushi]], which is still scored as yakuman. As a result, it is double yakuman.
* [[kokushi musou]] is double yakuman when completed on a 13-sided wait.
* [[chuuren poutou]] is double yakuman when completed on a 9-sided wait.
* [[suuankou]] is double yakuman when completed on a [[tanki]] wait. This is also the only way that the hand can win by [[ron]].


===EMA===
===EMA===
The [[European Mahjong Association]] (EMA) has decided to apply a made-in-Europe variant of this rule, which specify particular yakuman as double.  For example, [[daisuushi]] hands count as double yakuman per the 2012 RCR rules.
The [[European Mahjong Association]] (EMA) has decided to apply a made-in-Europe variant of this rule, which specify that yakuman are not cumulative and double yakuman is not scored, with a single exception: a [[daisuushi]] hand is double yakuman.
