Multiple yakuman: Difference between revisions

Latest revision as of 12:55, 9 August 2024

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

Daisuushii

Agari:

* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 1 yakuman.
* Full scoring: 2 yakuman.

Shousuushii + Tsuuiisou

Agari:

* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 2 yakuman.
* Full scoring: 2 yakuman.

Suuankou + Daisangen

Tsumo:

* Single yakuman cap: 1 yakuman.
* Cumulative single yakuman: 2 yakuman.
* Full scoring: 2 yakuman.

Suuankou tanki + Daisangen + Tsuuiisou

Agari:

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

The largest hand possible

Tsuuiisou + Suukantsu + Suuankou tanki + Daisuushii

Agari:

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

-'''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.
 ==Scoring==
-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.
