Guess Who?

• This is a game for two or more players.
• One of the players chooses a character that is most probably known by other players.
• The character can be either a real person (contemporary or a historical figure) or any fictional character (including non-humans).
• Other players try to find the character by asking "yes/no" questions. The player who finds the character chooses a new character and the game continues. 
• The yes/no answers have to be correct and consistent. When the player thinks neither ‘yes’ nor ‘no’ fits for the question, he/she may say ‘not applicable’ rather than giving a misleading answer.

• An example game where the character in the above picture is chosen can go like this:

-       Is it an imaginary character?
-       No.
-       Is it a she?
-       No.
-       Someone known for good things?
-       No.
-       Is it a politician?
-       Yes.
-       Is he still alive?
