C9++ is a semi-open setup for 13 players, originally designed by Fiasco of MafiaScum. The idea behind a C9++ setup is that for every power role the town rolls, anti-town forces also grow stronger.
To set up a C9++ game, randomly choose 7 numbers between 1 and 100. Each number corresponds to a letter, which signifies the type of power role rolled:
Number |
Letter |
1-50 |
T (Townie) |
51-65 |
C (Cop) |
66-75 |
D (Doctor) |
76-85 |
V (Vigilante) |
86-95 |
M (Mason) |
96-100 |
B (Blocker) |
Then based on the letters you have, consult the following list to add roles to the game (where not specified, they are town roles):
Cop Roles
C = 1-Shot Cop
CC = Cop
CCC = Cop, 1-Shot Cop
CCCC = 2 Cops
CCCCC = 2 Cops, 1-Shot Cop
CCCCCC = 3 Cops
Doctor Roles
D = Doctor
DD = Doctor, 1-Shot Doctor
DDD = 2 Doctors
DDDD = 2 Doctors, 1-Shot Doctor
DDDDD = 3 Doctors
Vigilante Roles
V = 1-Shot Vigilante
VV = Vigilante
VVV = Vigilante, 1-Shot Vigilante
VVVV = 2 Vigilantes
VVVVV = 2 Vigilantes, 1-Shot Vigilante
Mason Roles
M = Innocent Child
MM = 2 Masons
MMM = 2 Masons, Innocent Child
MMMM = 3 Masons
MMMMM = 2 Masons, 2 Masons (i.e. two separate pairings)
Blocker Roles
B = Roleblocker
BB = Roleblocker, 1-Shot Roleblocker
BBB = 2 Roleblockers
BBBB = 2 Roleblockers, 1-Shot Roleblocker
Scum Roles
TTTTTTT = Mafia Goon, Mafia Godfather; Serial Killer + 1 Bulletproof Vest*
TTTTTT = Mafia Goon, Mafia Godfather
TTTTT = Mafia Goon, Mafia Godfather; Serial Killer + 1 Bulletproof Vest
TTTT = 2 Mafia Goons, Mafia Roleblocker
TTT = 2 Mafia Goons, Mafia Roleblocker; Serial Killer + 1 Bulletproof Vest
TT = Mafia Goon, Mafia Roleblocker, Mafia Godfather
T = Mafia Goon, Mafia Roleblocker, Mafia Godfather; Serial Killer + 1 Bulletproof Vest
0 Ts = Mafia Goon, Mafia Roleblocker, Mafia Godfather
*The original setup allows the serial killer to choose either investigation immunity or a bulletproof vest, but this is not possible with the current software - you can't edit a role's modifiers after the game has been randed. Typical precedent has dictated giving the vest by default.
Then, add Vanilla Townies until you have 13 roles.
For example, I rolled the following numbers using random.org: 91, 32, 92, 81, 87, 83, 93. Converting them to letters gives me MMMMVVT. This means my setup will have the following power roles:
- 3 Town Masons in a group together
- Town Vigilante
- Mafia Goon
- Mafia Roleblocker
- Mafia Godfather
- Serial Killer + 1 Bulletproof Vest
That's 8 roles, so adding 5
Vanilla Townies completes the setup.
