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.
In some variants the STAR shape is replaced by a CIRCLE.
There is an edition dated 1978 with different packaging.
