{{main|Kazoe yakuman}}
* [[European Mahjong Association]] (EMA)
Normally, a hand worth 13 han or more is classed as a [[yakuman]].  However, this value is reduced to [[sanbaiman]].
* [[101 Kyougi Renmei]]
* [[Japan Professional Mahjong League]] (JPML)
* [[Korean Mahjong League]] (KML)
* [[Mahjong Union|Mu Mahjong μ!]]
* [[Nihon Pro Mahjong]] (NPM)

{{main|Tochuu ryuukoku}}
*'''Kuitan''' (open tanyao): On
Abortive draws are completely omitted from the tournament.
*'''Atozuke''': On
 
*'''[[Oka]]''': Off
== Uma ==
*'''[[Uma]]''': {{uma|+15|+5|-5|-15}}. If players tie, uma is averaged (e.g. if two players tie for 1st, both gain +10).
{{main|Uma}}
*'''[[Abortive draws]]''': None
The uma for the tournament uses {{uma|+15|+5|-5|-15}}. However, in the event of a tie between players, then the uma is adjusted to accommodate the tie.
*'''[[Chombo]]''': -30 (as of the 2022 edition), applied after [[uma]].
** Before 2022: -20.
*'''[[Yakuman]]''': Hands can score a single yakuman maximum.
*'''[[Kazoe yakuman]]''': Off - a 13+ han hand is scored as a [[sanbaiman]].
*'''[[Pao]]''': On for [[daisangen]], [[daisuushii]], and [[suukantsu]].
