Kartenglück und Schicksalszeichen (Cards and signs of fortune) is a supplement to the deck of Inrah cards that is available separately. Inrah is the Tarot variant of Das Schwarze Auge and is used for fortune telling and also for a gambling game called Boltan.
The book gives a short history of Inrah, presents several ways to deal the cards for fortune telling and how to interpret the cards. It presents the rules for Boltan (a poker-like game) and five different variants of play. The last part of the book deals with using the Inrah deck as a tool to supplement skill checks, use them as action points or to generate adventures.
