Drinking Games - Killer

To play you need 5 people to play and a deck of cards. (Note: you change the cards accordingly to suit the number of people you have, this is just the suggested version) Person who suggests game draws out 4 black cards and one red card Cards are placed on playing surface and mixed around by a player not being the one who chose the cards. All players choose one card from the five on the playing surface the player that picks that gets the red card Is the "killer". Everyone stares at eachother and at the right time the "killer" winks at another player that player must put in his card and chug drink or shoot, according to what you are drinking. This goes on and The players become "detectives" trying to figure out who the killer is if they are wrong (each player only gets one guess.) they must drink if there guess is wrong. If it is right then the killer must then drink what is left of each players drink..
