So “lynch-or-lose”, basically the day of the game where village loses the game if they don’t lynch a wolf. Wolves win when they hit parity, aka there’s the same number of wolves as villagers, so if there are only one or two more villagers than wolves, if village mislynches a villager, either wolves win immediately or after their successful night kill. So in this game specifically at LyLo only, once you vote it can’t be unvoted or changed, so you’ve gotta be really sure about your vote. This is the first time I’ve played a game like that, it’s a rule for the real game so I think AM’s trying to make this as close to the real deal as possible.
