Chuuren poutou: Difference between revisions

'''Chuuren poutou''' {{kana|九連宝燈}} is a [[List of yaku#Yakuman|yakuman]] and a specific instance of [[chinitsu]]. It contains the 13-tile pattern 1-1-1-2-3-4-5-6-7-8-9-9-9 of the same suit, plus any one more tile from the suit. In addition, the hand must be closed. Calling a [[kan]] on the 1 or 9 invalidates the yakuman.

A special pattern of chuuren [[tenpai]], '''junsei chuuren poutou''' {{kana|純正九蓮宝燈}} ("pure churren poutou"), results in a 9-sided wait. It occurs when you complete the 1-1-1-2-3-4-5-6-7-8-9-9-9 pattern without any duplicate tiles. Unlike the 13-sided [[kokushi musou]], this 9-sided wait is formed naturally with four sets and a pair. Some [[yaku variations|rule variations]] consider this a [[double yakuman]].
