I am now a (very slow) Scrabble KING, although I do feel a bit of a sleazy cheat pulling all these odd words out like they actually mean something. It's more for proper Scrabble games with people who care I suppose, not friends and family who are just playing for a bit of fun. Careful you don't end up with no friends to play with anymore if you do purchase this!
Found this to be a very good reference book as well as being very helpful. I am new to this absorbing game and have learned a lot in the few short weeks I have had it Definitely recommend this book for beginners
