Ryuukyoku
Ryuukyoku is also known as an 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, players in tenpai receive points from those in noten, i.e., players not in tenpai.
Nearly 40% of professional games go to an exhaustive draw due to players immediately dropping out of the race when a player declares riichi.

Point exchanges
If some players are tenpai and some are not, a total exchange of 3,000 points are evenly split between among the tenpai players from the noten players.
Point exchanges are as follows:
- 0 players in tenpai: No points exchanged.
- 1 player in tenpai: All players in noten pays 1,000 points to the tenpai player.
- 2 players in tenpai: Each player in noten pays 1,500 points, each player in tenpai receives 1,500 points.
- 3 players in tenpai: The single player in noten plays 1,000 points to each player in tenpai.
- 4 players in tenpai: No points exchanged.
Hand progression
Any leftover riichi bets on the table are placed near the counters until collected by the winner of a hand.
The count for honba increases by 1.
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.
