Black Stories is a card game series by Holger Bösch with collections of tricky and morbid stories. The aim of the game is to guess, based on the short description text of a story, what the framework conditions and circumstances are that led to the situation described. For this purpose, the players may ask the game leader questions, which he may only answer with "yes" or "no". The idea corresponds to that of lateral puzzles. Black Stories are therefore often known as "laterals" or "yes-no puzzles".
