Nagashi mangan
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 ryuukyoku, 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.
- Some rules may only count nagashi mangan if the player's own hand is closed.
As the name implies, a successful execution of nagashi mangan rewards the player in the amount of a mangan tsumo. This cancels out the regular tenpai settlements for ryuukyoku. A player does not need a tenpai hand to score this yaku.
Wind rotation depends on the dealer's hand. If the dealer is in tenpai, their seating is retained, even if did not score nagashi mangan. If the dealer is noten, the seating switches, even if they scored a nagashi mangan. (This assumes the rule of tenpai-renchan is used.)
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.
