'''Yakuman''' {{kana|役満}} are a special class of [[yaku]] (hand patterns) whose [[scoring table|point value]] is set to the maximum. These hands are considered rare and difficult.

These hands are considered rare and difficult. Traditionally, a single yakuman is the most points that any one hand can reach. However, some [[#Multiple yakuman|rule variations]] allow multiple yakuman to be combined. | ||

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 4th. Others are achieved in specific conditions, such as [[tenhou and chiihou]] being won on the first draw. | ||
Among the yakuman, three in particular are significantly easier/more common than the rest: [[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 significantly easier/more common than the rest: [[suuankou]], [[daisangen]], and [[kokushi musou]].

While elusive, yakuman are not impossible. Players with a chance for a yakuman can benefit from going for said yakuman. Like any other decision, this choice depends on game state, such as the current point standings, number of tile draws left, and the current hand. | While elusive, yakuman are not impossible.

Playing more games will increase the chance of scoring a yakuman eventually. Naturally, luck also plays a role. When a yakuman becomes viable to aim for, a player should recognize the chance and seize it. | |||

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: | ||
