I'd say that creating a basic 'variation' of the game would be much easier, and much less intimidating than attempting to acquire rights. If you're adamant, however, on using that particular title, I'd suggest enquiring [email protected], the general licensing advisory of Warner. They may not be able to directly help you however, you may be put through to Warner Game, or Warner entertainment to speak further. I'd also suggest, if you are able to, make use of a lawyer, who has experience in licensing products (be it brands or things of that sort)for books.
I hope this helps, and if not, I hope you find the answer you're looking for books.
