My brother's idea:
Here are the basic rules:
1. A person comes up with a premise to a story(a few sentences, at most 5)
2. The premise's last sentence will be a question, which the other players will have to find the answer to.
3. The investigation consists in the other players asking yes/no questions from the story creator.
4. The winner is the one who will find the correct answer to the question.
5. When someone wins, then he will come up with his own story, and the previous story creator will share the entire story with the others.
The specific mechanics will be apparent and clear after a few exchanges with my brother...
PS: the premise of the story might be misleading...don't take anything in the premise for granted, take note of the precise information that is revealed
Enjoy!
