'''Ryuukyoku''' {{kana|流局}} is also known as an '''exhaustive draw'''. Sometimes, [[haiyama|all the tiles]] aside from the [[dead wall]] are drawn; and no player manages to produce a winning hand. Points are exchanged based on the number of players with a [[tenpai]] hand vs those who are in [[noten]] (not tenpai). | '''Ryuukyoku''' {{kana|流局}} is also known as an '''exhaustive draw'''. Sometimes, [[haiyama|all the tiles]] aside from the [[dead wall]] are drawn; and no player manages to produce a winning hand. The hand ends after the player with the [[haitei|last tile]] draw makes the last discard of the hand. If no one claims a win on that discard, then the hand simply ends. Points are exchanged based on the number of players with a [[tenpai]] hand vs those who are in [[noten]] (not tenpai). | ||
In this case, players in tenpai' reveal their hands and receive points from those in noten. Players in noten may choose to reveal their hands, but it is not required. Noten hands do not affect the point exchanges, when revealed. Though, players in tenpai are not particularly required to reveal their hands. Instead, they may opt to declare noten, despite having a tenpai hand. In exchange for keeping the hand hidden, a player loses points. | In this case, players in tenpai' reveal their hands and receive points from those in noten.

Sometimes, the ryuukyoku point exchanges is enough to determine the final position in games, especially in [[oorasu]] (the last hand). Dealers in tight point races need to take particular note about the need to attain tenpai or allow the game to end. It may be desirable to pass on a small winning hand in order to collect the payment from noten players instead. | |||
===Nagashi mangan=== | |||
{{main|Nagashi mangan}} | |||
A special case may occur where a player achieved [[nagashi mangan]]. Here, the payment exchange applied by ryuukyoku is replaced by a "reverse mangan tsumo" payment. The dealer pays 4000, while the other two players pay 2000 each. If the nagashi mangan is at the dealer position, then all three players pay 4000 each. | |||
==Seat rotation== | |||
[[Jikaze|Wind seat rotation]] is dependent on the dealer's hand state: tenpai or noten. If the dealer's hand is tenpai, then [[renchan]] is applied and wind seating does not rotate. If the dealer's hand is noten, then the wind seating rotates with an additional [[honba]] applied. | |||
==Chombo== | |||
{{main|Chombo}} | |||
Seldom, a player may actually call a noten riichi and the hand ends in ryuukyoku. Here, the player in [[riichi]] reveals a noten and is penalized for [[chombo]]. No wind rotation is applied, and no point exchanges are applied. The honba count is not increased. The next hand continues as if the chombo hand did not even occur. Of course, the appropriate penalty for chombo is applied and the game continues. | |||

Variation on ryuukyoku stems from the qualification of tenpai. Under some rules and conditions, some hands may be declared as noten instead, even if they appear to be in tenpai. | Variation on ryuukyoku stems from the qualification of tenpai.
