Crepe tape or sticky notes and pens are needed.
Everyone writes a person known to the group or an object (for children) or something funny on a piece of paper or a piece of tape. Now everyone gets a piece of paper sticked to their forehead so that the others can read it. Now everyone has to find out, “Who am I” that is, who is on his forehead. This is done by asking a series of yes and no questions. The others answer. Everyone can ask until they get a no for the answer.
