The basic concept of Detective Stories is quite similar to what Sleuth online game was offering in the past - you get a short, few sentences long story, often quite baffling or not providing with a lot of details. And that is it. From that point you can test your creative thinking what is the full story behind the described event.
There are clues available, if you have no idea how to start, and you can access the answer, but you should only use them as last resort, because it is after all a game, in which you should work out from available description the full picture.
Basically it is a single player game, you can just play alone, but as the creators described it, it should be played by at least two: one as a detective and one as game master (or host). The host knows the story, the detective can ask questions, to which the game master can only answer with "yes", "no" or "I don’t know".
It is interesting variation on old concept, plus most of the stories have nothing to do with crimes, so it could be played by kids as well.
