One suit plus winds or dragons, and nothing else.
Every numbered tile comes from a single suit. Winds and dragons are allowed alongside it, in any number. One tile from a second suit breaks the pattern entirely.
Drop the honours and it becomes Pure One Suit, worth 7. Honour pungs inside it keep paying on top of the 3.
