StoryCards: Die drei ??? – Buch der Finsternis is a storytelling game of sorts in which a player or team is confronted by a situation that presents them with two options for a journey. Which way should they go to solve the mystery? Once they choose, they lay down the card, then search for the appropriately numbered card that they chose. The more cards they lay down, the more they score. If a card is no longer available, however, then the game ends and the detective trio has failed.
