Good Rengay have
- a unifying theme that runs throughout. Superior rengay have more than one theme without the themes seeming forced; each verse responds, in some way, to the preceding verse;
- verses that can stand alone as poems
- a title that reflects the theme(s), but does not seem obvious;
- 2-line verses that are not simply 3-line haiku written in two lines.
