One Night Ultimate Werewolf Daybreak

Technically a stand-alone game, Daybreak plays best as an expansion to One Night Ultimate Werewolf, which was easily the most fun party game of 2014. To start, up to ten players are dealt one of many face-down character tiles, secretly assigning them to either the evil werewolves' team or the villagers' team. The game starts with a "night phase," where players close their eyes and take turns switching and messing with other players' tiles depending on each character's power. (Luckily, this phase is choreographed with the game's free iOS/Android app.)
During the "day phase," the players spend a few minutes lying, misleading, or trying to put together what happened during the night. Then a player is elected by vote to be killed, and everyone flips their cards to see who became what, and which team won. Daybreak brings new characters with fresh powers to the table—further revitalizing an already replayable game.
