This book is written for those who occasionally visit Las Vegas or Atlantic City for a vacation, or a couple days of fun. While there, one can't help but drop coins into the slot machines in hopes of hitting a jackpot. They are drawn to the casino's gaming floor like a metal paper clip is to a magnet by the sound of coins dropping into the slot machine's metal pan, flashing lights, strange slot machine sounds, and screams of those hitting a jackpot. Upon reading this book, one will have an insight on how a slot machine functions, and be informed of a method of play that will increase one's odds of winning. Let me be honest, though, and say that no matter what method one plays the slot machines, luck is a major factor in whether one wins or not. To know what slot machines to patronize, and having a good method of play will certainly increase one's luck. One will also be informed when it's time to depart the casino's gaming floor, and I can only hope they heed the advice as not to ruin their vacation.
