Bo Rad

Bo Rad is a 1992 Macintosh puzzle game by Joe Fleck, modeled closely on the classic code-breaking game Mastermind. The player tries to deduce a hidden sequence using only feedback about how many guesses are correct in color and position, a tight loop of logic that suits the Mac's mouse-driven interface.

Mastermind, Mac-style

Each round the computer hides a secret pattern. You enter a guess, and the program reports how many pegs are right in both color and position versus right in color only. With each pass, the search space narrows until the code falls.

Why it works on the Mac

Mastermind translates naturally to a point-and-click interface: rows of choices, a clean feedback column, and instant visual scoring. Bo Rad keeps the layout simple and readable, in line with System 7-era HIG conventions.

System support

The game is a 68k application targeting System 7.0 through 7.6. It runs comfortably on later Mac OS 8 and 9 systems and inside common 68k emulators for modern play.

Preservation

Bo Rad is preserved on Macintosh Garden as a small shareware curiosity from the early 90s, representative of the many one-author logic games that filled BBS and FTP shareware libraries of the period.
