Influentia is a card game based on classic trick-taking card games. In each trick, players play one of their Resource Cards. The winner of the trick may choose one of the City Cards from among those available or the Resource Card that was just played by another player. The other players keep the cards they played as these will allow them to activate a variety of effects once they have two identical Symbols. After 3 rounds, the player who has won the most victory points wins the game.
