A variation of a very old board game, my son and I worked for a week on this for his sophomore math class project. We didn't spend a lot of time on the graphics, but we worked diligently on the logic. The result is a playable game that is reasonably challenging in easy mode, and quite a brain-teaser in hard mode.
We designed easy mode with
8 color pegs and a 4-color code, while hard mode has
16 color choices with a 6-color code. The player gets 10 guesses, and hints are provided with red and white pegs. For more info, a "How To Play" text file is included.
Enjoy!
