ABSTRACT
Any game can be considered a grey game. Classic games are a special example of the grey game, while grey game theory is an expansion in the field of incomplete information (or bounded knowledge). Grey games are the broadening of the binding conditions of detailed knowledge (where precise information gains of game strategies can be mastered before implementation) for classic games, so we cannot solve all the problems of this area completely by applying classic game theories to a grey game. The solving processes of a grey game are more difficult and complicated than those for classic games and involve many more factors.
