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]].

As a general rule, for every +1 han, the hand doubles in value until it reaches 4 han. There is a "[[mangan|cap]]" at 2000 base points (5 han; 4 han 40+ fu), after which the doubling stops. Once reaching the cap, fu no longer matters for points, and han generally is reduced in value.

== Aotenjou ==
{{main|Aotenjou}}
[[Aotenjou]] is a rarely played variant which removes the [[mangan]] limit. Under aotenjou:
*Each han doubles the hand value without limit. E.g., a 5 han 30 fu hand is 8000 in standard rules, and 15360 in aotenjou.
*Fu matters even for hands with 5 or more han.
*Yakuman are scored as 13-han yaku.
