One Hundred and One Monochrome Mazes from IBM is a maze action game which will run only on the monochrome display, using high intensity, low intensity, and black colors for different elements of the environment. Players can select the maze number, marker speed, sound options, and type of scoring - timed or point value. Scoring is a combination of maze level, marker speed (1-9), and time of completion.

There are 11 levels of difficulty, each level has 10 mazes, the last one has only one final level. The more difficult mazes brings new hazards, such as trap doors or invisible walls. The game is played with the numeric keypad only.

Display Support

Since the game runs in 80x25 text mode, it may not be immediately obvious why a monochrome display adapter is required; after all, any color card can support this mode just as well.
The most likely technical explanation lies in the format of the level data. Hidden traps and triggers are designated by a different attribute byte (in video memory) from that of the surrounding floor. On monochrome cards (MDA or Hercules) this difference is not visible on screen, but on CGA or compatible standards, these locations would show as differently-colored characters - which would obviously defeat the purpose.
