The game

It has been a while since I made my last guide. This game has some familiar aspects of some board games I really like, so I made a guide for it.

For the asassin it's really easy. If you at first agree with everybody that says someone else is the assassin, the others will slowly think everyone but you is the assassin. Then gain trust from people that don't trust you that much, and you will get 80% to 100% trust from everyone.
You don't need to assassinate anyone, at least I didn't when I was on my "5 people killed" medal run.

For the boss take note who helps each other. The assassin will (almost) never say someone else isn't the assassin. At least I've never had that. Just draw eight circles on a piece of paper in a shape of all the people that sit on the table, and tally next to each circle that represents one person sitting on the table if someone helps another person. An example of this is drawn at the bottom of this guide.

For the 50-point medal:

A meeting makes everyone accuse/help someone three times. I call one of those three times a round.
During the first round of the meeting, use the method described above (in italic) to determine who certainly isn't the assassin. You'll want a maximum of three people left at the end of the first round who haven't helped anyone yet.
During the second round, accuse one of those three and help anyone who does. If you have enough influence points left you can also try to defend people who aren't the assassin, so they don't take away votes at the end of a meeting.
In the third round there should be one guy left who hasn't helped anyone. That's probably the assassin. Accuse him, help anyone who does that too. If you can, defend people who aren't the assassin and don't have much trust %.
Now vote for the assassin and hope you made others trust him little enough to vote for him too.
