Spying Them All

WHAT YOU'LL NEED:
Personal things or Childhood Photographs of every guest in the party
Paper and Pen for each guest
A notice board or desk to display all things numbered

HOW TO PLAY:
Collect the personal things or the childhood photographs of your party guests stealthily, so that they do not know about it.
Distribute pen and paper to everybody and ask them to guess, to whom the displayed photograph or personal thing belongs.
Person with the most correct guesses is the winner.
