Welcome to the sex party. Your goal tonight is to score three times or have one unforgettable threesome.
Clusterfuck is played in two phases. First, players go around the table and pass each other sexy notes. Once each player has passed notes, everyone closes their eyes and points to the people they want to hook up with with one or both hands.
Then, everyone opens their eyes. If two players are exclusively pointing to each other, they score, and each gets one point. If three players are all pointing to one another and forming a threesome they each get three points for their feat of sexual teamwork. The first player (or players) to get three or more points wins the game. A successful threesome immediately ends the game, just like Quidditch.
