In Knock! Knock! 3-6 players compete to host the coolest, hippest Halloween party possible. The game is a game of bluff as the only way partygoers can join a party is if you open the door for them; but since they are arriving from the other players, who knows if they will have a good or bad effect on your party? Guests include headless horsemen, vampires, and computer geeks (ewwwww, who wants those at a good party?)
The game is playable by anyone ages 7 and over and is a great family game as hands take only 10-20 minutes to play.
