4.1 Scoring a winning hand
First find the number of fan (doubles): Add the number of yaku (at least one), the number
of red fives, the number of dora tiles, kan dora tiles and in case of a riichi hand the number
of ura dora in the hand. This sum is the fan value of the hand.
Then the base value of the hand, the minipoints, is calculated. Round the number up
to the next 10. (e.g. 32 minipoints are rounded up to 40). For hands with five or more fan
the minipoints are irrelevant.
of the hand can now be found in the tables here
To this value is added 300 for each counter on the table in case of self-draw, and 100
in case of winning on a discard. In addition any riichi bets from players who didn’t win
the hand are collected by the winner.
In case more than one player wins at the same time, the discarder settles the score
with each winner individually. Each winner receives the value of the hand including the
value of counters in play.
In case more than one player wins at the same time, the riichi bets from players who
declared riichi without winning go to the winner closest to the discarder’s right. Riichi
declarers that win, always get their riichi bet back.
You always get minipoints for one the three following ways of winning:
Minipoints for winning:
Concealed on a discard 30
Seven pairs (no further minipoints are added) 25
Otherwise (Self-draw or Open hand) 20
Add minipoints for pungs and kongs in the hand. Chows have no minipoint value. If
the winning tile finishes a pung, it counts as a concealed pung in case of self-draw, and it
counts as an open pung in case of winning on a discard.
