A village hides a few werewolves. Every night the wolves secretly kill a villager. Every day the survivors talk, accuse each other and vote to lynch someone they suspect.
Starting and joining
Anyone can start a game with /startgame. Tap Join under the message, or send /join, before the timer runs out; a game needs at least 5 players. Start the bot in a private chat first: that is where it tells you your role and gives you your buttons. Changed your mind? /flee leaves the lobby. /nextgame tells you when the next game starts.
Your role
When the game starts the bot sends you your role in private. Keep it secret, or don't: bluffing is part of the game. /rolelist lists every role, and the roles page explains each one.
Night
Roles that act at night get buttons in the private chat: the wolves choose a victim, the Seer learns someone's role, and so on. Choose before the night ends.
Day and the vote
Everyone wakes up and learns who died. Talk in the group: share what you know, or what you want the others to believe. Then the vote starts: every living player gets a list of names in private, and the player with the most votes is lynched.
Winning
The village wins when every wolf and every other killer is dead. The wolves win when they are at least as many as the rest. Some roles play alone: the Tanner wants to be lynched, the Serial Killer wants to be the last one standing.
