Players are encouraged to know yaku, their han values, and how much points a given hand is worth. This knowledge may help with various game decisions, particularly when [[Riichi strategy|calling riichi]] or [[Betaori|abandoning the hand]]. | Players are encouraged to know yaku, their han values, and how much points a given hand is worth.

As a general rule, for every +1 han, the hand roughly doubles in value until reaching 4 han. There is a "[[mangan|cap]]" at 2000 base points (5 han; 4 han 40+ fu) - a hand that scores this much is called a [[mangan]] hand. Once reaching mangan, fu no longer matters for points, and han is reduced in value. | As a general rule, for every +1 han, the hand roughly doubles in value until reaching 4 han.

The highest-scoring combinations are the yakuman patterns. A hand completing a yakuman is not scored for han and fu, but depending on the rules, it may be possible to combine multiple yakuman for an even larger hand. | The highest-scoring combinations are the yakuman patterns.

==Mangan== | |||
[[Image:Mangan tsumo.png|thumb|right|250px|Hand scoring a mangan via [[tsumo]].]] | |||
'''Mangan''' {{kana|満貫}} is a point cap which limits the impact of han and fu. Worth 8000 points in total (12000 points for the dealer), mangan is reached with 3 han and 70 fu, 4 han and 40 fu, or 5 han. Once a hand reaches mangan, increasing fu will no longer affect scoring, and han has a reduced effect. | |||
Below mangan, every han roughly doubles the hand's score. Past it, each han can still increase the hand's score, but in set intervals. These values, like mangan, have their own names: | |||
* 6-7 han: '''Haneman''' {{kana|跳満}} = 12000 for a nondealer and 18000 for the dealer; 50% more than mangan (x1.5) | |||
* 8-10 han: '''Baiman''' {{kana|倍満}} = 16000 for a nondealer and 24000 for the dealer; 100% more than mangan (double) | |||
* 11-12 han: '''Sanbaiman''' {{kana|三倍満}} = 24000 for a nondealer and 36000 for the dealer; 200% more than mangan (triple) | |||
* 13+ han: '''Kazoe yakuman''' {{kana|数え役満}} = 32000 for a nondealer and 48000 for the dealer; 300% more than mangan (quadruple) | |||
** Some rulesets don't use kazoe yakuman, in which case 13+ han hands are worth sanbaiman. | |||
* Yakuman: Points are the same as kazoe yakuman. | |||
* Multiple yakuman: Points are the value of yakuman multiplied by the number of yakuman the hand contains. | |||
===Kiriage mangan=== | |||
'''Kiriage mangan''' {{kana|切り上げ満貫}}, or "rounded up mangan", is a [[Scoring_variations#Kiriage_mangan|scoring variation]] that modifies mangan. When kiriage mangan is enabled, a 4 han and 30 fu hand, as well as a 3 han 60 fu hand, are considered mangan. The difference between a regular 4 han 30 fu hand (worth 7700 or 7900 points for non-dealers) and mangan is not very large, so these values are rounded up for convenience. | |||
Kiriage mangan is reasonably common to see in real life play, though most computer clients do not use this rule. | |||
