Everyone has an index card or sticker on their forehead.
On the sticker is written the name of a country; the person should not know the country that they are. The participants must then walk around and ask “yes or no” questions about their country which will give them clues as to what country they are.
For example, one could ask “Does it rain a lot in this country?”
The purpose of the game is to figure out what country you are.
