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 reveal their hands and receive points from those in noten (players not in tenpai). Players in noten may choose to reveal their hands, but it is not required. Doing does not affect the point exchanges.
Nearly 40% of professional games go to an exhaustive draw due to players immediately dropping out of the race when a player declares riichi.
