Riichi Competition Rules Scoring
Riichi Competition Rules: Overview Gameplay Scoring Penalties & Errors Resources

A minimum of one yaku is needed to call for mahjong. Emphasis is placed on concealed hands. After winning add up all the minipoints and yaku then convert the values using the charts below.

Initial Points

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.

  • Win by a discarded tile: Discarder pays winner full score plus values for other players as well.
  • Win by self-drawn tile: All player's pay the value of the winner's hand.


If you have less than five yaku in your hand you must add up any mini points 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 yaku in your hand you must use the limit hands chart below.

The winner of the hand will also collect any riichi bets on the table. If there is more than one winner, the player closest to the discard collects the riichi bets.

Consider the following example. East (東) round; South (南) position; Dora: b6.gif. Ura-Dora: d8.gif.

Dora (x2) 2 fan
Fully Concealed (menzen tsumo) 1 fan
Full Straight (itsuu) 2 fan
5 fan
Payment 2000/4000

Since the value is 5 fan we can skip counting the minipoints (fu) and go directly to the limit hands table. A self-drawn 5 fan hand (mangan) receives 4000 from the dealer and 2000 from each non-dealer (total of 8000).
