The first player to complete three of these missions wins.
You don't sit at a table to complete missions, though. This game is designed to run in the background of whatever else you have going on, which means you can play it anywhere: at home, on holiday, in the office, or yes, at a party.
Mission examples include getting a player to compliment your hair, hiding this card in a jar and getting another player to open it for you and making up a word and getting a player to ask what it means.
