This is significantly different from standard Mastermind in that the code is made up of two elements - each position has one of five shapes and one of five colors. Consequently there are now three different kinds of key pegs to give responses with.
The interior is in excellent condition and is more than complete - there are a lot more shape and color chips than the rules specify. The box has some wear and tape on one end (it's intact so I don't know why the tape is there). The rules are in multiple languages including English.
