Fooblitzky is a board game-style computer game published by Infocom in 1985 and designed by a team including interactive fiction authors Marc Blank and Michael Berlyn. Brian Cody illustrated this game while working for infocom. [source: briancody.com] It is unique among Infocom titles because (among other reasons) it was the first game Infocom released to incorporate graphics beyond ASCII characters. Like most Infocom titles, it was written in highly portable ZIL and made available for an array of popular computer platforms, including the Apple II, IBM PC, and the Atari XL and XE series.
Infocom marketed Fooblitzky as a "Graphic Strategy Game", and gameplay was compared to that of Clue and Mastermind. Two to four players travelled around the virtual city of Fooblitzky, spending "foobles" and attempting to deduce what four objects were needed to win the game (and then obtain them).
Players purchased objects in stores and could visit City Hall to have their possessions evaluated. Much in the same style as Mastermind, the player would be told how many of their objects were correct, but not which ones.
Each box contained four sets of laminated game boards and erasable markers which could be used to track the progress of a game. Two sets of documentation were also included: a set of "quick-start" guidelines ("The Bare Essentials") and a more detailed set ("Official Ordinances").
