Mafia is a party game for about 7 to 12 players and one moderator. A few players are secretly in the Mafia. Everyone else is an innocent townsperson, and the town has to work out who's in the Mafia before it's too late.
- Deal. The moderator sets the number of players and taps Deal roles. Pass the phone around: each player types their name, looks at their role in private, and hides it before passing it on.
- Night. Everyone closes their eyes. The moderator reads each line on the screen. The Mafia wake and silently point at a player to take out. The Doctor wakes and points at someone to protect. The Detective wakes and points at someone. The moderator says "I'll nod if they're in the Mafia and shake my head if they're not", then nods or shakes. The moderator taps each pick.
- Morning. Everyone opens their eyes and the moderator reads who was taken out in the night, unless the Doctor saved them.
- Day. Everyone talks it over. Then count down from three and everyone points at one player. The player with the most votes is out, and the moderator reads out their role.
- Repeat until one side wins. The town wins when the whole Mafia is out. The Mafia wins when there are as many of them as everyone else.
Players who are out stay quiet for the rest of the game. They can keep their eyes open at night and enjoy the show.
