it is "game to find out fellows". All participants are given a certain word (eg elementary school). This word is common to all, but only one person is a different word (eg kindergarten). A person given a different word becomes "word wolf". And everyone talks about the given word. As word wolf has only one word different, gradually a slight gap will occur. If you can see this gap and the participant can identify Wolf Wolf, you win if you escape without bullfight, Wolf Wolf is the winner. The point of this game is that I do not know if I am a majority or a minority (Word Wolf).
