In this meeting, we will play.. Mafia!
Mafia is a game created in the USSR by Dimitry Davidoff in 1986,modelling a battle between an informed minority and an uninformed majority.
Players are secretly assigned roles: either "mafia", who know each other; or "townspeople", who know only the number of mafia amongst them. In the game's "night" phase the mafia covertly 'murder' a townsperson.
