Mastermind (1990)(Hasbro)

Mastermind was a computerized (DOS) version of the famous code-breaking board game, Mastermind, which game was introduced in 1971 (see Wikipedia entry for further historical details)  It became a huge success shortly after it was introduced. introduced.  Mastermind was available by the mid-1980s as a DOS program, put out by a company called Spinnaker.  One competed with the computer to break codes.  It was a great game in its original computer permutation, as it was/is in board-game format - still sold today.  Not sure how Hasbro got involved but I suspect they acquired Spinnaker.  The game is currently available in Windows along with a variety of portable apps  - don't know how the modern version compares with the orginal Dos permutation.
