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. | |||

While the term "ryuukyoku" is usually used to refer to an exhaustive draw in Japanese, on occasion this may be ambiguous, as the term technically refers to any draw (cf. [[tochuu ryuukoku]], {{kana|途中流局}}). When ambiguity occurs, it may be referred to as '''tsuujou no ryuukyoku''' {{kana|通常の流局}}, which translates roughly as "usual kind of draw". | |||
Nearly 40% of professional games go to an exhaustive draw due to players immediately [[betaori|abandoning the hand]] when a player declares [[riichi]]. | |||

Tenpai is the state of the hand waiting on just one tile to claim for a win, either by draw or discard. Even if the hand does not win, it can still be awarded a small amount of points at the end of the hand, after all possible tiles are drawn and discarded. So, hands at tenpai during ryuukyoku still has some value. | |||

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. | |||

Often, a hand may end in a draw, where players had declared riichi. Any leftover [[riichi]] bets on the table are placed near the counters until collected by the winner of a hand. If the dealer is not in tenpai, then the seat winds rotate normally. If the dealer is in tenpai, the seat winds remain the same for the next hand. | Often, a hand may end in a draw, where players had declared riichi.

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. | |||
:{{#mjt:12m567p888s11z}} {{#mjt:0z33m0z}} | |||
Some many consider this hand as noten, despite needing one tile for completion. However, that one tile is one among the tiles called for a closed kan by the same player. The hand is also [[karaten]], or impossible to complete. All possible tiles for completion are used with the dubious [[kan]] call. So, instead of gaining points, the player loses points at ryuukyoku. | |||
:{{#mjt:123333m567p888s11z}} | |||
At some point, the hand looked like this. As it stands, this hand is actually complete. The kan was closed, and no [[Naki|open call]] was made. The tiles already constitute the necessary [[Mentsu|tile groups]] and the [[Jantou|pair]]. Therefore, the hand should have been properly called for a [[Agari|win]] or tsumo instead. | |||
