A minimum of one yaku is needed to call for mahjong. After winning add up all the minipoints (fu) and yaku/han then convert the values using the charts below.
As these rules are based on tournament play there are no initial starting points. If you are playing casually everyone can start arbitrarily with 25000 points.
A minimum of one yaku is needed before going out. When there are five counters out (due to Dealer's consecutive wins or draws) a minimum of two yaku are needed to go out. Dora and red five tiles do not count towards the yaku minimum. The dealer usually pays more upon losing but on the same token receives more when winning.
| Double Ron. (Variation) Allowing two players to win on a discard. The discarder pays the full score of both players. Riichi bets go to the next closest player to the discarder. Players who declared riichi are privileged to the ura and kan ura dora bonus. |
You need at least one yaku in order to call mahjong. Upon scoring, if you have less than five han in your hand you must add up any fu and follow the values based on the charts below. The minipoints (fu) are then rounded up to the nearest multiple of 10. If you have five or more han you do not add up any fu directly use the limit hands chart below.
All patterns below qualify as a yaku and show their han value. Players who score a yakuman or double yakuman do not count any additional han. Note that the following is a comprehensive list of yaku, some of which may not be recognize by all players. It should be agreed upon which yaku can be counted before playing.
