There are hundreds, even thousands of books out there that offer to teach the secrets of Roulette. Some of these books are actually pretty good, others don't really help out the average gambler much. Some of the secret strategies require you to start out with a bankroll that is too big for them to be effective for the everyday gambler. Some are better suited for average people because they let you start out with a smaller bankroll.
Roulette Secrets or Common Sense?
Some books that offer to teach you the secrets of Roulette really only give you simple pointers that anyone who knows even a little about gambling can already tell you. They tell you things like you should win big in only a few spins and then walk away. Well, sure, everyone knows that. But what if you want to play more than a few spins, then what do you do?
Other books tell you "secrets" of Roulette like sound money management. Don't bet more than you're willing to lose, they say, or don't get so caught up in the moment that you lost track of how much you're betting, or you could lose big. These are definitely good pointers that every gambler should know, but I would hardly call these secrets and I certainly would not pay money for one of these books.
The only Roulette secrets books that are worth the purchase price are ones that can teach you a unique, innovative system for reducing the house advantage and increasing your odds of winning. These are worthwhile and can show you how to start with a small bankroll and earn a lot of money over a longer period of time. Make sure to look for the words "Roulette system" or "winning system" somewhere in the description of the book, otherwise you might end up with a book that tells you such non-secrets as "the advantage is with the house." If you didn't know that, you should think twice before putting your hard earned money on the line, because you're most likely going to kiss it goodbye.
