- No players may talk outside of the game thread during the day phase.
- Mafia members, masons, cult members, and some other groups may be able to talk outside the thread during the night phase.
- Voting is generally done in some specific format (such as Vote: SomePlayer) to make it easier for the Moderator to keep count.
- In most games, once someone reaches a majority that player is lynched and the moderator reveals that player's role.
