'''Multiple yakuman''' involve hands with more than one [[List of yaku|yakuman]], as the name implies. While regular yaku may be stacked in one hand to raise value, the same can be done with different yakuman, where applicable.
'''Multiple yakuman''' can be scored if a hand qualifies for more than one [[List of yaku|yakuman]]. Some rules do not allow multiple yakuman.


In terms of scoring, the number of yakuman in the hand serves as a multiplier to the base yakuman point value.  As a result, extremely high scoring hands are made possible.
When a hand would score multiple yakuman, the number of yakuman is multiplied by the base yakuman value; a double yakuman is worth twice as much as a single yakuman, a triple yakuman is worth thrice as much, and so on. A hand with yakuman does not score [[han]] and [[fu]], so [[kazoe yakuman]] can never combine with other types of yakuman.
 
If, in addition to one or more regular yakuman, the hand would also be a [[kazoe yakuman]], no extra yakuman is added for this. For regular yakuman, [[han]] from normal yaku and dora are not counted.

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.
There are three main variations to the multiple yakuman rule. Some rulesets only allow single yakuman, due to the huge value of a multi-yakuman hand.


===Single yakuman cap===
===Single yakuman cap===
 
Multiple yakuman are disabled; a hand can only score one yakuman, maximum. In other words, yakuman do not stack. Many professional organizations in Japan use this rule.
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===
===Cumulative single yakuman===
 
Allow yakuman to stack. However, each individual pattern is always worth a single yakuman (e.g. [[daisuushii]] is worth one yakuman and not two). This rule is most notably used in [[tenhou.net]].
Some groups, most notably [[Tenhou.net]], do not award double yakuman for any specific hand. However, multiple yakuman are still possible, if two (or more) different yakuman are completed in the same hand. Most commonly, this involves [[tsuuiisou]] alongside either [[shousuushi]] or [[daisangen]]. [[Yaku_compatibility#Yakuman|Other combinations]] are possible, but they are very rare.

Allow yakuman to stack. In addition, certain yakuman patterns are worth double on their own:
* [[Daisuushii]] is always a double yakuman, as it is more difficult to complete than the lesser hand [[shousuushii]].
* [[Kokushi musou]] is a double yakuman when completed on a 13-sided wait.
* [[Chuuren poutou]] is a double yakuman when completed on a 9-sided wait.
* [[Suuankou]] is a double yakuman when completed on a [[tanki]] wait. This is also the only way that the yakuman can win by [[ron]].


Under full scoring rules, four yakuman patterns may produce specific instances, that are worth double yakuman.  Under this ruleset, the combination of yakuman are applied.  In addition, particularly rare and difficult hands are worth double the score value of a normal yakuman by themselves.
In a few rulesets, [[tsuuiisou]] in [[chiitoitsu]] form can be worth a double yakuman - this is known as the [[local yaku]]man, [[daichisei]].


* [[Daisuushi]] is more difficult to complete than the lesser hand [[shousuushi]].  So, daisuushi is worth double.

* [[Kokushi musou]] is double yakuman when completed on a 13-sided wait.

If the optional yaku [[daichisei]] is being used, since it is necessarily a special case of the single yakuman [[tsuuiisou]], this is another case where a single yakuman can be upgraded to double yakuman.
These values are multiplied by the number of yakuman in the hand (assuming multiple yakuman are used).

Combination of Chinrotou and Suukantsu in this one hand [1].

Multiple yakuman can be scored if a hand qualifies for more than one yakuman. Some rules do not allow multiple yakuman.

When a hand would score multiple yakuman, the number of yakuman is multiplied by the base yakuman value; a double yakuman is worth twice as much as a single yakuman, a triple yakuman is worth thrice as much, and so on. A hand with yakuman does not score han and fu, so kazoe yakuman can never combine with other types of yakuman.

Scoring

There are three main variations to the multiple yakuman rule. Some rulesets only allow single yakuman, due to the huge value of a multi-yakuman hand.

Single yakuman cap

Multiple yakuman are disabled; a hand can only score one yakuman, maximum. In other words, yakuman do not stack. Many professional organizations in Japan use this rule.

Cumulative single yakuman

Allow yakuman to stack. However, each individual pattern is always worth a single yakuman (e.g. daisuushii is worth one yakuman and not two). This rule is most notably used in tenhou.net.

Full scoring

Allow yakuman to stack. In addition, certain yakuman patterns are worth double on their own:

  • Daisuushii is always a double yakuman, as it is more difficult to complete than the lesser hand shousuushii.
  • Kokushi musou is a double yakuman when completed on a 13-sided wait.
  • Chuuren poutou is a double yakuman when completed on a 9-sided wait.
  • Suuankou is a double yakuman when completed on a tanki wait. This is also the only way that the yakuman can win by ron.

In a few rulesets, tsuuiisou in chiitoitsu form can be worth a double yakuman - this is known as the local yakuman, daichisei.

Point values

Dealer ron Dealer tsumo Non-dealer ron Non-dealer tsumo
48,000 from the discarder 16,000 from all players 32,000 from the discarder 16,000 from the dealer; 8,000 from the non-dealers

These values are multiplied by the number of yakuman in the hand (assuming multiple yakuman are used).

Example multi-yakuman hands

Agari: 
* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 1 yakuman.
* Full scoring: 2 yakuman.
Agari: 
* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 2 yakuman.
* Full scoring: 2 yakuman.
Tsumo: 
* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 2 yakuman.
* Full scoring: 2 yakuman.
Agari: 
* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 3 yakuman.
* Full scoring: 4 yakuman.

The largest hand possible

Agari: 
* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 4 yakuman.
* Full scoring: 6 yakuman.
