Kara's right - the best way to learn is to play!
It's definitely not as complicated as it looks when reading through the threads.
But, because I need a quick break from finals...
Basics:
- Typically the game is divided into day cycles and night cycles (in these games, the day/night cycles typically kind of coincide with actual day/night). Games last a variable length of time; the most common length on this site seems to be around 8-12 days.
- There are groups of good guys (villagers) and bad guys (werewolves). Sometimes there are more groups, but the basics are just good vs. bad.
- At the start of the game, none of the villagers know who the wolves are. All of the wolves know who the other wolves are because they are put into a special group PM that is opened by the moderators. Which players are on each team is decided randomly (using "rng" or a "random number generator" system) by the moderators prior to the game start.
- The goal of the village is to lynch all the wolves (eliminate them by voting to lynch them during the day time). The goal of the wolves is to kill all the villagers by telling the moderator who they want to kill each night (usually one villager per night). The game ends when all of the wolves are lynched or the number of remaining villagers is equal to the number of wolves -- whichever happens first.
- Villagers decide who to lynch by talking about who they find suspicious (online, that means posting in the game thread). Wolves also post in the thread and pretend to act like villagers so they don't get caught.
- Lynches are majority rules: each player submits their own vote by posting it, e.g. Lynch Pippy. Moderators tally the votes, and whoever has the most votes at the end of the day cycle is lynched.
- Once players are lynched or killed by wolves, they are eliminated from the game. So, players will try to convince people to vote to lynch someone else.
- In many games, private messages (PMs) are opened up as extra lines of communication between individual players. The extent of these communications is up to the game designer. Wolves almost always have their own group PM where they can talk about their strategy without the village "hearing" what they are up to.
- Special Abilities (e.g. "seer" and "protector") are often given to villagers and to wolves at the start of the game to help them towards meeting their win conditions. These are often referred to as Roles, because in themed games you will typically get assigned a character along with your role. For example: in the Lion King game, I was Scar -- a wolf who could avoid being lynched a few times. So, I was on the wolf team, Scar was the role, and lynch avoidance was the ability. Roles and abilities can get very complex and the exact allocation changed for every game based on who designed the game. In noob games, typically the abilities will be pretty sparse/straightforward and your manator can help you figure out how to use your ability if you are given one. Players without abilities are referred to as "vanilla" or "vanillagers," if they are on the village team.
General guidelines:
- it is good form to submit a lynch vote every day!
- active participation in the game helps you figure things out, hence it can help your team win (pro tip: on SDN you can "watch" the game thread so you get alerts when things are posted in the game thread & therefore keep track of it more easily).
- If you are given a special ability, it is good form to submit the name of the player on whom you want to use your action every night. Submissions happen in a private role PM between you and the moderator.
- Moderators aka mods design the game (pick a theme, choose the # of wolves vs. villagers, determine what special abilities they would like to give to players) and keep the game running by talking up lynch votes and executing all of the night actions submitted by players (e.g. killing the night kill targets submitted by wolves). They are usually available to answer questions about roles and abilities, but may not answer all of them if it would be detrimental to the fun of the game to give too much away. Be nice to them; they put a lot of work into these games! 😉
(Can maybe format this later so it's not a giant wall of text...)
