"As for random.org: is there a way to use that website to randomly generate Mafia roles *without anyone in the game knowing who they are*? I don't know of one."
Go here ->
https://www.random.org/lists/One name per line, enter the name of every participant, and click "randomize". The top five names are the
mafia members.
There's no way any way anyone else can view the results. Of course, that means you must trust your game master, and that the game master cant play.
