C9

After 60 or 70 games of the Original Newbie setup, it became obvious that there was a Breaking Strategy of having the Cop roleclaim on Day One and then engaging in a series of Investigations while automatically protected by the Doctor until the Doc was found and killed by the Mafia. While this setup was still basically balanced, it led to a deterioration of the quality of play and lent itself to a Follow-the-Cop mentality, not good in a teaching game. Instead, a semi-open setup known as 'C9' (see below) was devised:

• 1 Cop, 1 Doc, 2 Mafia, 3 Townies;
• 1 Cop, 2 Mafia, 4 Townies
• 1 Doc, 2 Mafia, 4 Townies
• 2 Mafia, 5 Townies,

with the players unaware of which variant was chosen for that particular game. Officially this should be done at random with a 25% probability for each type, although some mods did not follow that instruction or chose one secretly.

The name 'C9' comes from Norinel, the List Moderator for Newbie Games, who used it as a hexidecimal shorthand for the binary sequence 11001001 - and if you have to ask more than that, look at this post.
