Ryuukyoku is also known as the "exhaustive draw". Sometimes, all the tiles aside from the dead wall are drawn, and no player manages to produce a winning hand. In this case, the hand ends in a draw. In this case, player(s) tenpai receive points from those in noten. A hand in tenpai is one that needs just one more tile, either by draw (tsumo) or discard (ron) to win. However, that needed tile was never claimed. Nearly 40% of professional games go to an exhaustive draw due to players immediately dropping out of the race when a player declares riichi.
Examples of tenpai hands:
Examples of noten hands:
No matter what, the total exchange of 3000 points are evenly split between among the tenpai players from the noten players. Any leftover rīchi bets on the table are placed near the counters until collected by the winner of a hand.
Point exchanges are as follows:
- 1-player in tenpai: All players in noten pays 1000 points.
- 2-players in tenpai: One player in noten pays 1500 to one player in tenpai. Likewise, the other player in noten pays 1500 points to the other player in tenpai.
- 3-players in tenpai: The one player in noten plays 1000 points to each player in tenpai.
- 4-players in tenpai: No points exchanged.
- 0-players in tenpai: No points exchanged.
If the dealer is not in tenpai, then the dealer indicator moves to the right; and that player becomes the new dealer. If the dealer is in tenpai, then the dealer indicator remains. For both cases, the count for honba increases by 1.
