Designing for the Milton Bradley Company, toy inventors Marvin Glass Associates penned the board game Which Witch? in 1970. The game draws upon several precursors in design, such as Mousetrap--for some of the action features, and The Game of Life--for the 3-D board design. Which Witch? made for a happy haunted house and Halloween-themed game for young children. There are no real reading skills necessary, after a grown-up introduces the game's simple mechanics.
