An adventure in the twisted, wicked Wizard of OZ The Wicked Wizard of Oz is a strange sort of a book. In fact, it is a portal to another world, the Marvellous Land of Oz. As well as the book itself, you will need two dice (or a standard pack of playing cards), a pencil and an eraser. Using these tools, and a simple set of game rules contained within the book, you will take on the role of the one of the protagonists of L. Frank Baum's The Wonderful Wizard of Oz on a new and perilous quest as they find themselves called upon to save the world once more.
