Tried playing it but i didnt understand shit. Was a jailor but didnt know how to play xD
Yeah, sometimes you're unlucky with more advanced roles. Better to watch some videos of it to get an idea of how to play. Or look at the role descriptions.
As a jailor, your job is to jail someone every night (There's an icon on the top that looks like a sun *Only shown during the day*) and pick a person that you think could be evil (Mafia, serial killer, etc). Ask the person for their role and if they say a town role, add it to your last will, saying that person is this or that. The Last Will is at the top as well next to the sun icon.
You can execute the person if you feel they are evil but if you're wrong, you can't execute anymore but you can still jail people. The Serial killer can kill you if you don't decide to execute him though so it's best to put the persons name on your Last Will the moment you jail the person.
Such as:
N = night
N1 - jailed Brothership - claims to be the sheriff
N2 - jailed MisterkNiss - claims to be medium
