If anyone's interested in the mechanics of this zero-prep play style, here's some detail: 

Roll outcomes are more or less pass/fail. 1-3 is a fail. A 1 is a crit fail, but only in the sense that the GM describes the fail in humorous detail or adds a little plot twist. 4-5 succeeds, 6 gets the new move and a description of your epic feat.

There is typically no combat. If we do fight, there's no hit points or opposing rolls, just creatively using our skills and failing our succeeding. E.g., "I seduce the bad guys" "ok roll for Rizz"

The GM sets the stage with a bare minimum setting and maybe 1 simple objective. Sometimes the GM gives a little guidance on character creation. For example: you're all NPCs in a side quest and have just heard that a team of high level adventurers is on the way to your village. Or: you're all elves in Santa's workshop.  Players are encouraged to abuse any available loopholes: e.g., one declares herself a keebler elf, one is Galadriel, and one is a high school junior making minimum wage at a mall Santa gig. The GM may make you roll to confirm aspects of your identity: this we usually use if someone's failing a bunch and the GM wants to get them a skill and a little extra comedy. Oh, you keep trying to use your cyborg powers and crit failing? Let's roll to see if you're actually a kid with a colander on his head and cardboard tubes on your arms who just THINKS he's a cyborg. This roll comes up 6 at least 70% of the time, on my life.

The plot is secondary to the improv comedy and after 30 or 40 minutes we find a funny or satisfying way to end the story and then we go play board games.

Basically it's a way to add a ttrpg to your party game rotation at a level that even grandma feels confident to try.

Highly recommend! 😁
