'''Nagashi mangan''' {{kana|流し満貫}} is a special [[yaku]]. Unlike all other possible hands, this yaku emphasizes the discards, rather than the hand itself.  As for the [[Jikaze|dealer rotation]], only the dealer's hand matters in relation to [[tenpai]].  Even if the dealer loses points due to nagashi mangan, the seating may be retained if the hand is in tenpai.  That is assuming the rule of tenpai-[[renchan]], as opposed to agari-renchan.

Speed Extremely slow
Difficulty Very hard

Nagashi mangan 「流し満貫」 is a special yaku. Unlike other yaku, it is scored based off your discards, rather than the hand itself.

Scoring nagashi mangan

In order to score nagashi mangan:

  • The hand must play all the way to exhaustive draw, meaning no one can win before all the tiles have been drawn.
  • Every discard of the player must be a terminal or an honor tile.
  • No tiles may have been called from the player's own discard pile.
  • In some rulesets, the player's own hand must be closed to score nagashi mangan. (In online clients like tenhou.net & Majsoul, you do not need a closed hand.)

As the name implies, a successful execution of nagashi mangan rewards the player with points equal to a mangan tsumo. This cancels out the regular tenpai settlements at exhaustive draw. A player does not need a tenpai hand to score this yaku.

Wind seat rotation will depend on the dealer's hand. If the dealer is in tenpai, the seating is retained, even if they did not score nagashi mangan. If the dealer is noten, the seating switches, even if they scored a nagashi mangan. (This assumes tenpai renchan is used. If agari renchan is used, wind seats always rotate.)

If multiple players win with nagashi mangan, the different tsumo payments occur independently of each other. For instance, if East and South complete nagashi mangan, then their payments to each other will cancel out, and North and West will each pay 4000 to East and 2000 to South.

Timing at ryuukyoku

Rulesets may differ on the exact procedure to score nagashi mangan:

  • Some rules score nagashi mangan like a win, before players reveal tenpai hands. This means that nagashi mangan can score honba and riichi sticks, and noten riichis are not punished with chombo. Wind progression depends on whether East has won with nagashi mangan.
  • Some rules treat nagashi mangan like a bonus payment, not a proper win. Nagashi mangan happens at the same time as players reveal tenpai hands. The payment is not affected by honba or riichi sticks. Chombo takes precedence over nagashi mangan payments. If there is no chombo, then hand progression depends on whether East is tenpai.

Rule variations

Nagashi mangan is subject to a couple of rule variations. Some rulesets do not use nagashi mangan at all. It is often excluded when playing with physical tiles, due to players' tendency to forget about it.
