Rules in effect


Following discussions having taken place over the internet regarding rules and options in use at the club, we are publishing the list of rules in effect in Montréal, dating back to its last update in January 2014.

Summary of rules for advanced players, as commonly understood by the global riichi community:

  • Ari-ari style (kuitan and atozuke), without oka or uma. 25 000 points to start, must finish with 30 000 points or more.
  • A negative score ends the game. Extra hands exist and end as soon as someone goes over 30 000 points with a winning hand only (i.e.: no final victory by draw or chombo).
  • Ties exist. Riichi deposits are given to the winner(s).
  • All standard dora are in effect. Late flip rules apply except for closed kans. A rinshan win counts new dora, a chankan win never counts as having formed the kan in question.
  • Repeats follow nanba-renchan rules: you need to be tenpai in the East round, you need to be bounced out in South round.{TO BE DISCUSSED}
  • The repeat is increased by 300 points per extra hand added or transferred : 100 per player in the case of a tsumo win.
  • We count paarenchan as being the winning hand following the placing of 8 repeat counters, be they repeats (renchan) or transfers (changing oya in East round {+1}, loss of oya following a chombo {+0}).
  • All aborted hands (forced draws) are accepted, all while specifying that nine terminals require nine distinct terminals.
  • Double ron counts, triple is refused. A double ron allows to see the hand of the last player to check the possibility of a triple ron. {TO BE DISCUSSED}
  • Temporary furiten is lifted at the completion of the next turn played by the affected player (pick and discard / call and discard). A furiten in one’s own discards persists until the wait is changed, a furiten state in riichi is permanent.
  • Priority calls must be promptly made (0.5 seconds). Ron calls can override a simple call within 3 seconds of the discard only.
  • Ippatsu, double riichi and open riichi are all accepted at the club. Open riichi is banned from competition play.
  • Nagashi mangan (All terminal discards) counts. No calls, neither for nor against nor closed kan may be made by or from the concerned player.
  • Haitei tsumo and houtei ron count. We refuse “haitei rinshan” as 2 distinct yaku (totaling 2 han), the term itself is a contradiction. Briefly, rinshan can never be haitei and only can count the one 1-han yaku.
  • The list of tolerated yakuman : Tenhou/chiihou (miracle starts), kokushi musou (including the closed kan override), ryuuiisou (all green, with or without the dragon), paarenchan, daisharin (22 to 88 in the same suit, all three suits accepted), kazoe yakuman (counted yakuman of 13 han+ as a last resort, not cumulable), as well as the non controversial daisangen, daisuushi, shousuushii, tsuuiisou, chinroutou, chuuren poutou, suuankou, suukantsu.
  • Double yakuman are counted as such, and are cumulable.
  • Responsability (pao) is in full and maximum effect. Daisangen, daisuushii, suukantsu as well as throwing a live tile for a completed kan (daiminkan) leading to victory. Any sum added by repeat counters is also borne by the responsible player. For yakuman, a ron win costs him half and a tsumo win costs him everything in the hand.
  • Minipoints worth specifying are of 4 fu for a pair of double-dominant winds and of 0 fu for a replacement tile.
  • False ron is a serious fault, penalized as chombo. {see note 1}.
  • Dropping six tiles or more from the wall is a serious fault. The dead wall carries no extra penalty.
  • chombo is considered as paying a reverse mangan. An extra penalty is levied against any player committing a serious fault if another player has a tenpai-ready hand potentially worth a yakuman, even if the necessary tiles are already dead. The oya who commits a serious fault loses his deal and the seat winds turn, except if there is a chance of winning after paying the chombo penalty. In this extreme case, another hand must be played without rotating the seat winds.
  • A victory can cancel a chombo payment. Two simultaneous chombos implies two payments to be made, if the fault of one is not dependant on the second.
  • Minor faults are sanctioned 1000 points. The only intermediate fault leading to a dead hand penalty is from picking or revealing from another player’s hand. A noten riichi or an illegal kan override the noten payments or of the presumed hand, replaced by the chombo payment.
  • Renhou and all crap (shiisanputa) are mangan only.

1. We believe in the “actions speak louder than words” theory, because some players have problems articulating consonants. A falling hand without a call is accepted but is in no case retractable. This being said, “ron” jokes are also penalizable by a chombo payment. A simple call may be upgraded to a ron win as long as the call was not revealed, as well as within a reasonable timeframe.
