Don't Play the Slot Machines (Until You've Read This Book) should be titled Don't Buy This Book. This is the most useless book on gambling ever written. The only good thing that you can say is that the book is only 128 pages and you can read the whole thing at lunch, sans desert. The author provides such valuable insights as - most players lose and a few win. And, the plastic thing that casinos give you to carry your coins is a cup. Or, the place where coins fall is called a tray. Or how about this one - if you win a lot of money, the casino will pay you by hand. The back cover says the author's job is to answer customer questions in a South Dakota casino. If this is the type of advise he thinks South Dakotans need, he does not think much of the good people of that state. I would sell my copy, but it is not worth the postage. Save your money and put it in a slot machine.
