Subject, Skills, and Grade Level
It explores numerical symbolism and number theory in an experiential way. The numerical symbolism is partly used as analogy for other forms of prejudice, and partly to simulate monogamous and non-monogamous romantic and platonic relationships. This game would probably be most appropriate for a math class, or any other class concerned with stereotypes, how societies are built, or the marginalization of polyamory. I imagine running this game would require a progressive high school or college environment.

Time & Players
At minimum, it will take 15-20 minutes. The players may stop playing when they're ready. Theoretically, any number of players 5 or greater can play.

Rules, Tools, & Assessment
It is GMless. Everyone should carry a copy of the rules. You'll also need blank white masks, colored and black markers, and large white adhesive name tags.
