Everyone sits in a big circle and there is one person in charge of the game.
There will be 1 mafia or multiple mafias depending on what the game master (person in charge of game) wants and depending on how big the group is.
The object of the game for Civilians is to kill off all the mafias by accusing someone.
Meanwhile the mafias will be winking as "discreetly" as they can so they don't get caught at it by people. If you get winked at you die.
Also beware civilians if you accuse wrong you die as well.
