Mhm interesting, didn't know that it is seemingly just a German thing, only with some editions that are translated. The stories are often very hardcore, but nonetheless we played these as teens after School together or even in school. It's an analogue "card game", one side of the card is known to all who participate which contains the story and the other side is only known to one person which has the solution. The participants that don't know the solution only can ask yes or no questions to the one who knows the solution. I don't own one personally, and the only things I found on the internet are some images of these cards, but in german. You could try to translate one with Google Translate. If you search for black stories on the official store you can see that there are 135 different versions of it (some are called different colors/names, e.g. pink stories, which are more harmless stories for children or "pferde stories" which are about horses)
> After the meal, the queen died.
If the guests had been more boring, she would still be alive.
Translation (solution):
> A beauty queen (like e.g. Miss America) was invited to dinner every night after her election. To maintain her weight, she stuck her finger down her throat after each meal. At a reception she was involved in many interesting conversations and forgot to retire to the toilet after the main course. Her overfull stomach ruptured and she died as a result.
