From the Game's Introduction:
In|Compatible is a game about romantic relationships for three players.
Using a standard deck of playing cards, four smaller decks are formed that represent potential partners (with the suit being the important attribute of each card). Each player individually chooses a suit to represent themselves.
Cards are revealed as play progresses. If the partner's card has a suit matching the player's suit then a conflict ends perfectly. A different suit of the same color has a positive outcome. A suit of a different colour has a negative outcome. After each round, players may decide to change their partner.
The game runs for a dozen rounds, with players narrating the conflicts and consequences of their love lives throughout. At the end, the results can be scored by a number of points for each card revealed by suit.
