Chanta

Chantaiyao 「全帯么」 is a terminal and honor based yaku. For this yaku, every tile group and the pair must contain at least one terminal. To score chanta, a hand must contain at least one honor and one non-terminal tile, otherwise the hand will score junchan, honroutou, or chinroutou instead. This yaku is more commonly referred by its shorter name, chanta 「チャンタ」.

Formation

By definition, every tile group must include a terminal or honor tile. So combinations of tile groups involving 1-2-3, 7-8-9, 1-1-1, 9-9-9, and/or any honor pairs/triplet applies here. This brings about the limitations of the terminal tiles, by which they're at the ends of the 1-9 number scale. Often, this yaku is particularly made easier with tile calls; but closed hands are very much doable.

Compatability

Chanta's pattern is similar to junchan; however, the two can never combine as junchan implies a chanta hand. Honroutou likewise implies chanta and is thus incompatible. Chanta with toitoi or chiitoitsu actually forms honroutou instead of chanta, while chanta with chinitsu is actually junchan instead of chanta.

Chanta is incompatible with tanyao and ittsu because both of those require a group which is not a terminal or honour---in tanyao's case, it is required of all tiles in the hand, and for ittsu, a 4-5-6 sequence is needed.
