Mafia 79. 1/0

Why are some of them multicolored?

That's how I want it.

Is the "Roulette" a maniac, or is there no maniac?

Urban shooter.

Are 4 Mafia members enough for 15 players?

I think so. Considering the possibility of changing their characteristics if players feel that there is an imbalance. It is also possible to add one more Normal. But considering the activity, waiting for another person may take more than a day.
