Yakuman are worth 8000 base points. For a non-dealer, this would equal 32000 points for ron, or 8000/16000 points from tsumo. | Yakuman are worth 8000 base points. For a non-dealer, this would equal 32000 points for ron, or 8000/16000 points from tsumo. | ||
A [[kazoe yakuman]] is scored when a hand reaches 13 or more han. Otherwise, in standard rules, a hand cannot score both yakuman and yaku at the same time. In other words, if a hand contains a yakuman | A [[kazoe yakuman]] is scored when a hand reaches 13 or more [[han]]. Otherwise, in standard rules, a hand cannot score both yakuman and regular yaku at the same time. In other words, if a hand contains a non-kazoe yakuman, it effectively has 0 han. | ||
In [[aotenjou]], yakuman ''can'' score with other yaku. | In [[aotenjou]], yakuman ''can'' score with other yaku. Under those rules, each yakuman is treated as a regular yaku worth 13 han. | ||

Yakuman are rare and | Yakuman are rare and difficult. Most yakuman have restrictions that make them difficult, such as [[ryuuiisou]] only allowing 6 of 34 tile types, or [[shousuushii]] requiring 3 [[wind]] triplets and a pair of the fourth. Others are achieved in specific conditions, such as [[tenhou and chiihou]] being won on the first draw. | ||
Among the yakuman, three in particular are considered to be among the easiest to attain: [[suuankou]], [[daisangen]], and [[kokushi musou]]. Collectively, these three yakuman are known as '''yakuman gosanke''' {{kana|役満御三家}}, or "the three big families of yakuman". | Among the yakuman, three in particular are considered to be among the easiest to attain: [[suuankou]], [[daisangen]], and [[kokushi musou]].

The more games the play, the higher the chance you'll score a yakuman eventually. Naturally, luck also players a role. When a yakuman becomes viable to aim for, a player should recognize the chance and seize it. | The more games the play, the higher the chance you'll score a yakuman eventually.

The chance for a yakuman is not constant; it decreases as opponents grow in skill level. Higher skill opponents tend to have better [[tile efficiency]], so they can win normal hands faster, before a yakuman gets to form. | The chance for a yakuman is not constant; it decreases as opponents grow in skill level. There are multiple possible reasons. Higher skill opponents tend to have better [[tile efficiency]], so they can win normal hands faster, before a yakuman gets to form. They are more likely to defend once a yakuman threat is present. Also, the amount of "yakuman chasing" likely decreases at higher levels of skill. Example statistics: | ||

Some yakuman may combine if their tile patterns allow them to do so. The most common combinations involve [[tsuuiisou]] along with [[shousuushii]] and [[daisangen]]. [[Tenhou and chiihou]] can combine with any yakuman except [[suukantsu]], though this event is exceptionally rare. [[Kazoe yakuman]] may not combine with any other yakuman, since yakuman cannot be scored with regular yaku. | Some yakuman may combine if their tile patterns allow them to do so.

In some rulesets, a hand can only score one yakuman, even if a hand contains multiple. Others allow the yakuman to stack, e.g. a double yakuman, worth 64000 points, for suuankou + daisangen.
