Each round, everyone will choose their alignment for the round. This will determine how they will score points: for winning or not winning a trick.
To denote your alignment, you place your alignment dial in front of you, revealing your choice of either the hero or villain side.
The difficulty of being a villain depends on both player count and villain. If you slip up as the villain and win 1 trick, you might as well win more (even though you will score 0 VP, each trick you win is 1 VP that a hero won’t gain).
Note: There are a few story cards that can change your alignment during the round. For all hero/villain scoring, it’s only your end-of-round alignment and tricks won that matter.
