The Mystery Party Guest
All you need for this simle game is pencil and paper. People will walk around talking to each other and take notes as they do.
After about 20 minutes the host will read out a list of things about 1 person who has been chosen as the mystery guest.
Things like favourite things to eat, pastimes, where they went to shcool etc.
The first person to shout out the right person is the winner.
