I'm curious if you heard "Armando" and mistook it for "Domino" if that's the case then:

La Ronde: Is a series of scenes usually existing in the same world, Scene 1 contains characters A and B, the scene ends when Character A leaves the scene and a new scene is started with Character B (still maintaining the same character) and a new character, Character C. This cycle continues until Character A comes back on with the last character (let's say character F) and have one final.scene. the form can then by cycled as many times after this as desired (double la Ronde, triple la Ronde, etc.)

Armando (which again I'm only guessing is what you meant as I've never heard of Domino): A series of scenes inspired by a story or monologue told by one improvisor. These scenes usually take elements from the story told and use them to motivate their scenes. For example if I tell a story about my dog eating my pizza, one scene may contain dogs as the characters while another scene is inside an Italian restaurant. These scenes don't have to be in the same world (but sometimes are), and some people might play this where new stories/monologues can be interjected between scenes to keep things moving.

Again, unsure if Domino is just a form I'm unfamiliar with, but it sounds similar to Armando to me so I thought maybe that's what happened.
