Welcome to mafiascum.net!
Playing Mafia online for the first time can be a bit confusing, so this guide is here to point you in the right direction. If something isn't clear, or we managed to miss something entirely, feel free to ask questions in the forums.
The first step is registering. To register, simply visit to the registration page and fill out the form. You will need a valid email address, and when you have registered you will receive an email allowing you to activate your account.
Once you have registered, head to the Queue forum. This is where you sign up for all types of Mafia games. The Queue page contains detailed information on the Queue system. As a summary, here are the five types of games.
- Open Games - Open and Variable Open setups are those where either the entire setup is known ahead before players sign up, or how the setup is determined is known before players sign up. Setups are determined by the community and by player signups, rather than by the moderator. There is currently no limit for the number of games you may play at the same time. Signups take place at the Open Game Queue Thread. Open games are played in the Central Park subforum. Newbies are recommended to play in Open games or Normal games.
- Mini Normals - Mini Normal games have at most 13 players. Mini Normals with 9 or less players are known as Micro Normals. Games must meet Normalcy standards and are vetted for balance by a panel of experienced reviewers before they are run. Mini Normal games are a step up from Newbie games in that they are usually larger and the setup is not known in advance, but are still generally tame. In order to join these games, you will need to post in the Normal Queue that you want to be assigned to the next Mini Normal that will run. These are played in the New York forum. Newbies are recommended to play in Open games or Normal games.
- Large Normals - Large Normal games are games with over 13 players that are run with basic roles and rulesets. Games must meet Normalcy standards and are vetted for balance by a panel of experienced reviewers before they are run. In order to join these games, you will need to post in the Normal Queue and ask to be added to the next Large Normal that will be run. These games can be found in the New York forum. Note that while these games are straightforward, they will take a long time simply due to their size. Make sure you are willing to be committed to a lengthy game before you sign up. Newbies are recommended to play in Open games or Normal games.
- Mini Themes - Mini Theme games are based on a theme and for at most 13 players. Mini Themes with 9 or less players are known as Micro Themes. While these games do not need to adhere to Normal standards, most of the time, these games are advertised in advance so you can get an idea of what is different about them before you join. There are two games taking signups at any one time. To play one, post in the Theme Game Queue saying that you want to play, specifying which game you want to play in. Mini Theme Games are played in Coney Island.
- Large Themes - Large Theme games have over 13 players and are based on a theme (such as The Lord of the Rings, Star Wars, Ancient Greece, Aliens, etc.) or are otherwise varied enough that they cannot be classed as Normal. Because Large Themes can be fairly complex or confusing, they are not recommended for completely inexperienced players. Each Large Theme game has its own signup thread in the Queue. Large Theme Games are played in Theme Park.
Note that there may be a delay between when you sign up for games and when they actually start. This is common, especially in the Newbie queue where a precise combination of experience groups needs to be represented. Don't panic.
At the beginning of the game, the Moderator will secretly send everyone their role. The Mafia will know each other, while (in the basic game) everyone else will only know their own role.
The game has two phases, the first of which is Day. During Day, the Town must choose someone to Eliminate; they are trying to get rid of the Mafia, but the Mafia can lead them astray by casting suspicion elsewhere. Generally, players will vote for someone they think is Mafia (the Mafia will vote so that they seem to be doing this as well, and might even vote for each other to confuse the Town); when a player gets a majority of the votes, they are eliminated. Their role is revealed by the Moderator, and it becomes Night.
During the Night, the thread is locked and no one can talk publicly. The Mafia, however, can speak to each other privately to plot strategy and decide who to murder before the next Day begins. In this way, they can silence members of the Town who are threats to them. At the end of the Night, the murder is carried out and another Day begins. In effect, the Town gets to kill someone, and then the Mafia gets to kill someone.
The game alternates between Day and Night until either the Mafia are gone, or the Mafia have killed everyone else (or nothing can prevent the same).
The above suffices for a Vanilla game, but most games have roles other than just Mafia and Townie. These roles have additional abilities (which are usually used during the Night, though there are some Day abilities as well). Some more common roles are listed here.
Cop - Each Night, the Cop can investigate one player (by sending their name to the Moderator), and the Moderator will tell them whether that player is Mafia or not.
Doctor - Each Night, the Doctor can choose one player to protect (by sending their name to the Moderator). If the Mafia (or anyone else) tries to kill that player, that kill will be prevented.
Vigilante - Each Night, the Vigilante may kill another player (by sending their name to the Moderator).
Mason - The Masons are a group of players who are confirmed to each other as Town and can talk to each other at Night.
All of these roles are generally Town-aligned.
Serial Killer - The Serial Killer (often abbreviated as SK), like the Vigilante, may kill another player each Night (by sending their name to the Moderator). However, the Serial Killer is not on the Town's side or the Mafia's side. The Serial Killer wins when everyone else is dead.
Multiple Families - On occasion, in larger games there may be more than one group of Mafia. These act independently of one another, and must kill the other group as well as the Town in order to win.
Roleblocker - Each Night, the Roleblocker can choose a player. That player will be prevented from using their Night choice, if they have one. Roleblocker has been known to be a Town role as well as a scum role.
There are many variations on the above roles that will often appear in more complicated games; for more information, visit the Roles page.
