All players at the table are responsible for ensuring that each winning hand is scored correctly and to the maximum points.
First find the number of fan (doubles): Add the number of fan given by the yaku (at least one), 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). In case of a seven pairs hand, the hand is worth 25 minipoints and there is no rounding up. For hands with five or more fan the minipoints are irrelevant.
The value of the hand can now be found in the tables on
A-1. The tables are further described in
4.1.3. To the value in the table are added 100 for each counter on the table in case of self-draw, and 300 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.
When scoring is done with sticks, players should put the sticks on the table where all players can see them during the exchange. When scoring is done with sticks, players are obliged to count up their sticks when asked to by opponents. The game continues if a player’s score goes below zero; the player borrows score sticks from an opponent or the referee.
4.1.2Exact calculation of the hand valueInstead of calculating manually the value of the hand, the tables provided are recommended. For completeness, however, the calculation procedure is given here. For hands worth five or more fan, the table for limit hands is used. For hands worth less than five fan, the value is calculated thus:
The base value of the hand (the minipoints rounded up) are doubled by the number of fan plus 2. This figure is the base figure to be paid by all three opponents in case of selfdraw. For East, however, the figure is doubled one more time. East receives double payment, but also pays twice the amount of the base figure in case of an opponent’s self-draw. Payments are rounded up to the next 100, though never exceeding the value of a mangan.
In case of winning on a discard, the discarding player must pay for all opponents, incl. East, i.e. four times the base figure if the winner is not East, and three times the doubled base figure if the winner is East. The payment is rounded up to the next 100, though never exceeding the value of a mangan.
In addition to this is the value of counters and riichi bets on the table.
