Nord and Bert Couldn't Make Head or Tail of It

Nord and Bert Couldn't Make Head or Tail of It is an interactive fiction computer game written by Jeff O'Neill and published by Infocom in 1987. It was released simultaneously for several popular computer platforms of the time, such as the PC and Commodore 64. Nord and Bert was unique among Infocom games in that it used the game engine to present wordplay puzzles rather than an adventure story. It was Infocom's twenty-seventh game.
