Thank you for trying Master Mind! This is a HyperCard 2.0 stack that simulates the board game MASTERMIND. If you've ever played it, this should be pretty familiar. In this version, though, the computer randomly picks the hidden code pegs, so you don't need two people to play!

What do I need to run it?
You need a color Macintosh with a hard drive and at least 6MB of RAM. I'm pretty sure you need System 7 or later, too. You also need HyperCard 2.0 or later or HyperCard Player 2.0 or later.

How do I run it?
You can run it as-is from wherever, but make sure you allocate at least 2300K or higher to HyperCard. If you don't, you'll get error messages. You can set the allocation by selecting the HyperCard icon and choosing Get Info from the File menu. Next, type 2300 in the Preferred Size box. (If you can't change what's in the box, make sure HyperCard isn't running.) Close the Get Info window and you're done.

What's the point?
If you have never seen the board game, the object is to guess the sequence of code pegs in the hidden row. There are four code pegs in each row. The board is a grid of "holes" and you work with one row at a time, placing colored code pegs in a row.
After you place a row of code pegs, you are scored with score pegs. If there is a code peg in the row that you placed that matches the color of one of the hidden code pegs, but is not in the same column, you are given a white score peg. If there is a code peg in the row that you placed that matches the color of one of the hidden code pegs and is in the same column, you are given a black score peg. However, the score peg holes and the code peg holes do not correspond. In other words, if you get scored with one black score peg in the 1st key peg hole, that does not necessarily mean that the code peg in the 1st code peg hole is the matching one.

What does it cost?
It's free! I would certainly appreciate any contribution toward my college education, but there's no obligation to pay. Play with it, look at the scripts, give it away to friends, just be sure you don't give modified versions away, and be sure you always include this ReadMe file.
