In order to score the most points you need to ice players that are on the opposite side. You will receive 3 points for every player of the opposite team that you ice and 1 point for every player you ice that is on your team. For example.. if you are a Hunter, you will get 3 points for every Werewolf you ice and 1 point for every Hunter you ice. Your points are kept if you change sides in the middle of a 'wave', but the reward you receive at the end of the wave will be for the side you finish on.
