Tochuu ryuukyoku
Tochuu ryuukoku (途中流局) is more commonly known as an abortive draw. Specific game situations end a kyoku (hand session) without any player declaring a win or drawing all tiles from the wall.
Consequences
Causes
Suufon Renta
The first discard of each player is the same wind tile.
Kyuushuu Kyuuhai
A player's initial hand is composed of 9 different honor or terminal tiles. A player may call this, and the tiles are reshuffled. However, this option is denied when a discard is called before the player's turn. Instead of calling kyuushuu kyuuhai, a player may instead go for kokushi musou.
Suucha Riichi
All four players call riichi and the 4th player's discard is not a winning tile.
Suukaikan
Kan is called four times by different players. If all four quads are called by one player, play continues as to give the player the opportunity to score the yakuman, suu kantsu. The hand then ends in an abortive draw when a fifth quad has been called.
Sanchahou
Three players call ron on the same tile. In this case, no player wins the hand. Although, some allow this triple ron scenario to take place
