If you're unsure of how to play, I suggest reading this guide: http://cataldo.freeshell.org/mafia/mafiascum04.swf
Also this guide says something about someone having more than half the total votes (majority) to be lynched. You can ignore that. How it'll work here is that votes are tallied at the end of the phase. Whoever has the most votes, they get lynched.
If you have any further questions/the guide doesn't help, please let me know. :3
