To score honroutou, the hand must contain only honors and terminals. The hand must contain at least one honor and one terminal; an all honor hand would be [[tsuuiisou]], while an all terminal hand would be [[chinroutou]]. | ||

This yaku requires [[ | This yaku requires every tile to be a [[terminal]] or [[honor]] tile. [[Shuntsu|Sequences]] are not allowed, because a sequence always contains non-terminal tiles. Naturally, a concentration of honor and terminal tiles are required to even consider this yaku. A majority of honroutou hands are open, using [[pon]] to complete a triplet-based hand. | ||

It is impossible to score this yaku without at least either [[toitoi]] or [[chiitoitsu]]. So this yaku is, at minimum, worth 4 han. | |||
When factoring [[fu]], the combination of [[koutsu|ankou]] and [[koutsu|minkou]] (closed and open triplets) produces a fu count of higher than 10. The lowest possible fu is generated with 4 minkou, leading to [[tanki|hadaka tanki]] (lone pair wait). Adding the base 20 fu for any hand, this yaku is guaranteed greater than 30 fu; and with the rules of fu, that number is actually rounded up to at least 40 fu. Therefore, a honroutou composed of ankou and minkou is at minimum a [[mangan]]. | When factoring [[fu]], the combination of [[koutsu|ankou]] and [[koutsu|minkou]] (closed and open triplets) produces a fu count of higher than 10.
