Under usual rules, above 4 han, the score is capped. Fu become irrelevant and the hand is scored based solely on the han value. Since there are not a large number of possible hand values below 5 han, a [[scoring table]] is usually used, rather than calculating the values directly. | Under usual rules, above 4 han, the score is capped.

Both of these values are easily varied. Any game can set the start and target scores to any desired but workable numbers. Tournament play in particular often starts with 30,000 points. | ||
Under the rarely-used [[aotenjou]] rules, there is no scoring cap, and every hand is evaluated for fu and han, regardless of value. This can result in absurdly high hand values. | Under the rarely-used [[aotenjou]] rules, there is no scoring cap, and every hand is evaluated for fu and han, regardless of value.

'''Han''' {{kana|飜}} is the main portion of scoring, as each [[yaku]] is assigned a value in terms of han. Most of the yaku are valued at either 1 or 2, but the values, not counting yakuman hands, go as high as 6 han for a closed [[chinitsu]]. Some yaku are worth [[Kuisagari|one fewer han when open]], and some cannot be scored with an open hand, but many yaku are not scored the same regardless of whether the hand is open or closed. | '''Han''' {{kana|飜}} is the main portion of scoring, as each [[yaku]] is assigned a value in terms of han.

Afterwards, the [[dora]] are counted. Each [[dora]] tile in the hand counts as additional han. Dora are ordinarily worth 1 han each. Additional dora indicators may increase that value. | |||
In addition [[List of yaku|to knowing the yaku]], players are encouraged to know their han values. This gives them greater awareness on potential point values of the hand. This knowledge may help aiding in various game decisions, particularly when [[Riichi strategy|calling riichi]] or [[Betaori|abandoning the hand]]. | In addition [[List of yaku|to knowing the yaku]], players are encouraged to know their han values.
