A group in Hungary plays that the mafia must choose who to kill with their eyes closed-- as best we can tell, the moderator calls out the names of each player in turn, and each mafia member raises his hand when he hears the name of the civilian he wishes to kill. A majority of the mafia must choose the same civilian. If no majority is attained, the moderator, after coming to the end of the list of names, announces that noone was killed during the night. The mafia know who each other are, because they are allowed to see each other during the first night. However, because nighttime communication between them is forbidden, they must somehow communicate by secret signals during the day.
