'''Tochuu ryuukyoku''' {{kana|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 [[Ryuukyoku|drawing all tiles]] from the wall.  With the exception of kyuushuu kyuuhai, all cases of tochuu ryuukyoku are mandatory, when they occur.

'''Suufon renda''' {{kana|四風連打}} means "consecutively (ren) discarding (da) four (suu) winds (fon)".  The hand is aborted when all four players' initial discards are the same wind type.  In other words, every player [[haipai|started with hands]] containing the same wind; and each chose to discard that same wind tile.  At the moment North plays the fourth tile, the hand is reset; and all tiles are reshuffled immediately for the next deal.  Any [[Naki|tile calls]] would render this rule invalid as all four discards must be uninterrupted.  Even so, it would not have been possible, as three out of the four required wind type ends up in one player's hand anyways.

'''Kyuushuu kyuuhai''' {{kana|九種九牌}}, literally means 9 (kyuu) kinds (shuu) of honor or terminal (kyuu) tiles (hai). If a player's 14-tile hand after the initial draw is composed of 9 different honor or terminal tiles, the player may announce this and reveal his hand to abort the deal. If any such tile is paired, then they are counted together as one, while invoking this rule.  This option is only available if no tile call has interrupted the initial turn earlier.  Instead of calling kyuushuu kyuuhai, the player may play the hand normally, maybe aiming for [[kokushi musou]] or a terminal based yaku, such as [[chanta]].  This is the only case where the call for tochuu ryuukyoku is optional.

'''Suukaikan''' {{kana|四開槓}}is declared when four [[kan|quads]] are formed by different players. The rule literally means open (kai) four (suu) kans.  If all four quads are called by one player, play continues as to give the player the opportunity to score the yakuman, [[suukantsu]]. No other players are allowed to declare kan from then on. If the four quads have been formed by more than one player, hand abortion after formation of the fourth quad depends on the rules.
