In a werewolf game, players are divided into 2 or more groups. These are generally "good guys" (villagers) and "bad guys" (wolves) although these names and their composition will vary from game to game. There will typically be an approximate ratio of 4 villagers to 1 wolf.]
Players are usually assigned further into "roles". Roles can vary greatly from game to game, and frequently have "powers" or other rules assigned to them. Some standard examples include:
- Seer: Every night can divine someone's true identity (Will message the GM (person running the game) and say "Tell me Bob's identity tonight")
- Bodyguard: Can opt to protect a person from being killed at night, sometimes at risk of their own life (Will message the GM and say "Would like to protect Bob tonight")
Note that these roles may exist by different names or slightly varied rules. Additionally, there may be more than one player assigned to a given role (there may be two seers, or three bodyguards.) The players are not (usually) told beforehand how many of each role are present in the game.
When the game begins, the wolves all know who each other are. They will have a private conversation where they can coordinate and strategize with each other. The villagers on the other hand will have no idea who anyone is and must try to figure it out as the game proceeds.
Every day the town (villagers + wolves) have to vote on who they're going to lynch (kill, remove from game). The wolves are generally going to try to guide the voting so that a villager is lynched. The villagers will be trying to identify and lynch a wolf. This process involves a lot of bitching and arguing and lying and debating. Players will be having sneaky conversations pretending to be this role or that and generally trying to guide the voting their way.
At the same time, the wolves privately vote on one player to kill, who will typically (and obviously) tend to be a villager.
At the end of the 24 hour period, the GM goes over the day's activities. Depending on the rules, they'll tabulate the votes, kill someone via a lynch, kill someone via the wolves, and smite (kill) anyone caught breaking the rules. Then the next day starts. (A game day usually reflects a real-life day, and begins and ends at a time of the GM's choosing.)
The game ends when any preset victory conditions are met (all the wolves are dead, all the villagers are dead, etc).
