The participants are in pairs, and instead of telling each other facts about them selves they give the answer, to which the other person has to guess the question eg: "One of each", the other person then would guess things like, "Do you have brothers or sisters?" or "Do you have a cat or a dog?". It can get quite obscure eg. "17" 'The day of June that you were borne?' "nope" the number of sub saharan countries that you have visited? "Well done" Its a good fun game that can bring up some funny stuff.
