This osunds similar to a game we used to play called ‘Mafia’ (Yes, of course I know the mafia doesn’t really exist - of ocurse they don’t…). Basically you take a standard deck of cards, count out the number of cards as you have people. Include exactly 3 aces in the deck you are dealing from, shuffle, and pass out the cards. Those with the aces are in the mafia, there is one moderator who facilitates the game, and the rest of the players are the townspeople.
The moderator tells everyone to close their eyes (They are going to sleep for the night). The three mafia members do this and then open their eyes and using whatever silent means of communication decide on one victim for the round. They make this decision known to the moderator and pretend to go to sleep again (ie close their eyes).
The moderator wakes everyone up (tells them to open their eyes). Tells everyone who is ‘dead’ and let’s them start talking. Basically at this point people try to decide who is in the mafia. The mafia of course play along, but throwing everyone off as best they can. At the end of the round, the group must come to a majority decision on one person they think is in the mafia. The moderator has everyone go to sleep (close eyes again) and announces whether or not this person is in the mafia. Either way they are ‘dead’ and can not participate any longer. The mafia pick another victim, and the cycle repeates it self.
The game continues in this manner until one side or the other wins by being the only team with members still alive.
This game is a hell of a lot of fun because you get really deep into the psychology of fooling each other and breaking people’s non-verbals and other tells. I ruled at this game because I could play people so easily.
