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 regular yaku at the same time. In other words, if a hand contains a yakuman pattern, it effectively has 0 han.

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 thus difficult. Most yakuman have specific 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".

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 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. Also, they are more likely to defend once a yakuman threat is present. Example statistics:
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:
*[[Tenhou.net]], tokujou room, month of Mar. 2024: ~1/930.6 of winning hands are yakuman
*[[Tenhou.net]], tokujou room, month of Mar. 2024: ~1/930.6 of winning hands are yakuman
*Tenhou.net, houou room, month of Mar. 2024: ~1/1228 of winning hands are yakuman

The last thing any player should do is play into a yakuman hand. Alas, such plays do happen, even to the best of players. Of course, this is where [[defense]] is relevant, especially when a yakuman is an apparent threat. Then again, if a hand is closed, it's difficult to tell if a hand is a yakuman.
