This is a variant to the original Mastermind game. In this version, the player must crack a a code that consists of four elements, each of which consists of both a color and a shape. There are five different shapes and five different colors. There are now three 'Codemaker response pegs' instead of the two for the standard game. Black represents a completely correct response, blue represents a partially correct response, and white represents a correct pair in the wrong column. - BoardGameGeek
