Rene, as you can see by the responses, all you need to do is get one good book on casino gambling and it will answer your question and the next 15. <G> I've made a study of this over the years, and my additional point would be... Knowing the odds will not make you a winner, but it will prevent you from losing your faster by making stupid bets.

Here's the whole truth about roulette, and you don't have to read 50 books, or do major math studies to understand it. ALL bets on the roulette game are the same! (and before someone points out the 0-00-1-2-3, it's the exception and worse, so just ignore it) The house odds and your chance of winning are the same whether you bet on one number or 37 of 38 numbers.

It's fun, entertaining and the expected loss (EL) per hour is actually much lower than many other forms of gambling entertainment. Slots have a theoretical 2% house take, but trust me, they are one of the worst bets in the casino. So don't just look at the odds, look at what it costs per hour to play.

If anyone ever tells you they have a system that can beat the casino. There are a number of reasons why you can assume it's not true. One that was already mentioned, but is important. If someone did the casinos would change the rules. But you can add - If I had a winning system, would I tell anyone else? Would I be selling it for $25 or $100 instead of keeping it to myself and getting rice on the casinos money? There is no free lunch and there isn't a system that will beat the odds.
