(3 to 5 persons per team for "Mystery of Black Beard" and 3 to 6 persons per team for "Arthur and the knights of the round table" and "psychiatric hospital" and "The Orphanage"). The most "Enigmatic" : we have 5 rooms, so 5 teams can play in the same time, every in a different room (Total = 29 players for the same hour).
