MASTERMIND II - Lots of people have written digital MASTERMIND programs that create the code and give you the clues. This one will also let you make the code and give the clues. You can play either way or take turns with the computer. 10 rounds make up a game, and at the end of each round, player averages are displayed. Becase this is a machine language program, it takes the computer 3 seconds or less to come up with a guess.
MASTERMIND I - Same as above but written in BASIC for 4K machines. It only plays one way, the computer makes the code and gives the clues; you must break the code in 10 turns or less.
