Scum Reading and the Numbers Game

Scumreading is one of the most important parts of any good town. The numbers game is equally important, but more useful to roles such as the Vigilante.

What is scumreading?
Scumreading is the ability to analyse someone's actions and claims, as well as the way they write and talk, to determine whether or not they are evil. For example:

The Death Note that the Mafia have been writing is written in perfect prose. Apart from the Vigilante, one person talks in terrible prose and one person talks in perfect prose. The Vigilante shoots the person with perfect prose, and they are the Mafioso.

Why is it important?
Scumreading is valuable to the town because it provides an alternate avenue to figuring out evil roles. It also requires skill, which means that some people are better at it than others. Without scumreading, all investigation is purely down to chance. With scumreading, it is easier and more fun to narrow down roles that are harmful to the town.

How can I use it?
Scumreading can be learnt simply by taking note of the way evil roles talked before death. Most evil roles talk similarly, usually trying their best to be a help to the town so as to throw off suspicion, often redirecting interest to other evil roles apart from themself, or simply staying silent so no one cares about them. After using scumreading for a few matches you'll probably figure out how to use it properly, and to full effect.

What is the numbers game?
The numbers game is when there are fewer town roles than evil roles, and so the Vigilante will random shoot on the basis that he is more likely to hit a non-town than a town.

Why is it important?
Although less important than scumreading, the numbers game is still a very valuable tool to a town short on members. Even though the only person who can actually use it is the Vigilante, often times games hinge on whether or not the Vigilante chose to random shoot late game or not.

How can I use it?
Using the numbers game is easy. Simply match the roles dead in the graveyard to the spots they would fill in the role list. If there are more spots for evils or neutrals left open than there are for town, then playing the numbers game is a valid strategy.
