Nagashi mangan

Nagashi mangan (流し満貫) is a special yaku. Unlike all other possible hands, this yaku emphasizes the discards, rather than the hand itself. To score nagashi mangan, the hand must play all the way to ryuukyoku; and every discard must be all terminals and/or honors. In addition, none of the discarded tiles are claimed by tile calls. As the name implies, successful execution of nagashi mangan rewards the player in the amount of mangan.
