Billionaire Banshee is a game where everyone playing pretends they're single and looking for a soul mate. There are two card piles: exciting Perks and questionable Quirks. The player whose turn it is grabs one card from each pile and the combination of traits listed makes up their potential lover. For instance:
- PERK: They Have A Giant Robot
- QUIRK: They Have An Adult Baby Fetish.
Everyone secretly votes if that player would date the weird combination, and those that know their friend best get a point.
The game continues as you find out weird facts about your friends, and the person that knows their friends' preferences best wins!
