I have always loved this game.  I used to play Mastermind for hours with my siblings.  Now, I have shared this game with my kids.  We got this new version since my original game has been long lost.  This version seems to have some design flaws though.  The storage compartment is difficult to close and is always getting pegs stuck in the tiny holes on the side.  I have given up using it and store the pieces in a separate bag.  Also, it is hard for adult fingers to put pegs into the code maker section.  Otherwise, it is a terrific game.
