I found this book, Unlocking the Secrets of American Mah Jongg, to be a “must have” resource for any new person wanting to learn the game. Not only is it good for beginners but it is an excellent “refresher course” for seasoned players. Debbie has meticulously explained the fine details of the game so that all ages can understand the procedure for playing Mah Jongg. I am teaching my 12 year old granddaughter how to play and this book is invaluable! Thank you Debbie for such a wonderful teaching tool!!!
