From the introduction:
With music as the narrative backbone, cooperatively tell a story with your friends. A story that may very well be messy. A story that will end.
Games have rules. Dance 'Til Dawn has rules for narrating this story. Rules for shocking revelations. Rules for the length of story. Using the algorithms of music streaming services as a randomizer in conjunction with Scrabble tiles, players alternate narration throughout the session. The songs serve as a timer, when the song is over, another begins, and with it, a narrative shift.
Dance 'Til Dawn stories are driven by the music surrounding the players.
