Here's another way to look at it:  Let's say you bet $10 on every number, one bet on each of the 38 spots.  So you've just thrown down $380 in bets.  Only one of those numbers will win, and will pay 35 to 1, so you'll get back $360 (the $350 you won plus your original $10 bet on that number).  You bet a total of $380 but you walked away with only $360, so you lost $20.  That $20 you lost represents the house edge of 5.26% ($20 lost divided by the $380 that you bet; $20 ÷ $380 = 5.26%).
Those of you have gambled in a casino, even only a few times, have probably stumbled on the Martingale system, even if you didn’t know the word Martingale. You might have even figured you invented it. I know I did. It seems this is the very first concept most gamblers have and it is expressed in the following phrase: “I have to win sooner or later, right?” 
This roulette strategy is the equivalent of a YANS and it might even be more wild and crazy than that. It is based upon the assertion that a chaotic betting system can overcome the chaos of randomness. Two wrongs make a right; that kind of thing. Two wrongs don’t make a right and chaos versus chaos is just, well, chaos versus chaos, as you shall see.
World Best Roulette System – A convincing website that tells readers what they want to hear but in the end, we have no problem in labeling as a fraud because it has absolutely no chance of winning real money – even though it wins every time in fun mode. If you only take one piece of advice on this website it would be to avoid this system.
Few games in a casino are as intimidating to a beginner as the Roulette table – a sea of numbers, colors, and apparent impossibilities. Isn’t it easier to just go press buttons and watch reels spin on a slots machine instead? Surprisingly, no. While the Roulette table may seem confusing at first glance, in fact it’s a wonderfully simple casino game to understand… once you get the hang of it, of course. The key is to learn how to bet properly.
Some scammers will attempt to convince roulette players that betting trends can actually give them an edge even though the game is random. This section will explain why that can’t happen. Players should understand the bottom line of betting into a random game that has a house edge and that is – the house has the edge! Not too hard an idea to assimilate.
This betting option is one of the most diverse offered, with several different options. Basically, instead of just betting on one number, you have the option to bet on a group of numbers. This can be as wide of a range as 1-18 or 19-36, or as tight of a range as picking two numbers like 1 and 2. Ranges in between are also available for players to choose.

More than you’ll ever play. Somewhere between 100 to 500 or even more. Most of them use the same few wheels and live video footage provided by another company. So you can often play on the same wheel, but through a different online casino. The casino pays the live-video-provider a fee, but the casino itself is responsible for paying winnings. Although there are hundreds of live roulette casinos online, there are only about 30 different wheels.

There are countless other losing strategies but you’ll find they are much the same, just repackaged a different way. I don’t mean any disrespect to the creators of these and other losing systems. It’s only my intention to help people understand how to develop a winning strategy. In fact it took me around 10 years of developing roulette systems before I had anything that worked, or even understood the basics of why my systems failed. So I understand the mind of the typical roulette player.
Are online casino games (also known as Internet games) safe? Many of the gambling sites are owned by large casino companies or big businesses that are not looking for controversy or quick cash. They are in the games for the long run, just as land-based casinos are. So compared to the Internet world of three decades ago you will find most of these sites to be honest. There are two ways to check the honesty of an Internet online casino site. If the site passes either of the two tests, or both of them, you can have confidence that you are probably getting a fair deal. It can never hurt to check out gambling sites.
It's important to understand that the outcome of the roulette wheel is truly random.  If Black has come up for the last 10 spins in a row, the next spin is not more likely to be Red.  Black and Red are still equally likely. There's an old saying, "The wheel has no memory."  That means it doesn't know what it spun before, and even if it did, the wheel can't select what number comes up out of its own volition.  There's more on this in my article Debunking the Gambler's Fallacy.
Betting trends properly can reduce exposure to the house edge and increase one’s pleasure at the game. My trend betting strategy will cover how to play trends and enjoy them more! Hey, give these a try: My Hello Red/Black, Odd/Even, and High/Low trend betting. Or my The Counter Trend betting strategy. Or my really conservative trend betting system. And there’s more!

For any complete novices out there, a roulette wheel is made up of 37 numbered pockets (or 38 if you are playing American roulette – and as an initial piece of advice you shouldn’t, as it decreases your chances of winning!). Half of these numbers are coloured red and half are black with the ‘0’ pocket green. A small ball is introduced when the wheel is spinning and players must predict where the ball will land.
Step 2 is very easy. You need to break down your 24 chips in half, so you have two stacks of 12 chips. You then put one of the stacks of 12 on one of the dozens, and the other stack on another of the dozens. So you now have two out of the three dozen’s covered. If the ball lands in one of your dozens you will win 2-1 on your bet, so that will pay you 24 chips, plus the 12 from the winning bet will mean you now have a total of 36 chips.

They are equal in that there are 18 red and 18 black numbers on a roulette wheel. The 0 and 00 are both green numbers. However, there are 10 odd red numbers and 8 even red numbers. Also,the opposite is true in that there are 10 even black numbers and 8 odd black numbers. If you bet even and red or odd and black it seems you would have a slight edge as you would be covering 20 numbers instead of 18.
When a player gets to the upper reaches of the Martingale what is he looking to accomplish? Very little. Using the above dollar amounts, even should the player bet $640 or $1280, he is looking to win a mere $10. That is an awful lot to wager for a $10 win. At every step of the traditional Martingale the payoff is merely that $10. The untraditional Martingales are even worse! If you must allow yourself the Martingale then stick to the original.

Roulette Computers – These are cheating devices that, realistically, can only be used in real casinos. Without doubt, the use of an effective computer is the best and easiest way to win at roulette, but finding such a device is difficult. Then there’s the fact that in many countries and jurisdictions, they’re illegal and you will end up in jail for using one, so for this reason, we can’t recommend them.

Variations of games very similar to Roulette have been around for hundreds of years, therefore its exact origins are hard to trace. However, the version that we know and love today was devised by a French physicist, inventor and mathematician by the name of Blaise Pascal back in 1655. Of course, a game as seemingly complex as Roulette could only have been invented by a mad scientist – okay, he wasn’t really mad but he was a scientist. Pascal was trying to invent a perpetual motion machine – an experiment that failed in its original endeavor. For the non-science minded, a perpetual motion machine is a device that continues to operate without drawing energy from an outside source. A popular notion in the realm of “science” at the time. Though Pascal failed, he gave the world one of the most popular casino games in existence!
Yes, there are now plenty of online casino sites that offer real games as in r-e-a-l games! That’s right, you will have a live dealer spinning that real roulette ball and calling out the winners. A live dealer. A person. These are real games. It is important to carefully manage your money while playing casino games in your home as there can be (for some) a tendency to overdo it. Don’t let yourself become numb!
By the way, I want to take a moment to point out that this tidbit above about even money bets in Atlantic City is just one of the many fabulous bonuses you learn about for free on this site, which you might not find out about from books that cost actual money.  When I was learning about gambling, the first thing I did was to buy and read the book The Complete Idiot's Guide to Gambling Like a Pro. But in 332 pages they didn't see fit to mention the low edge in Atlantic City, so I didn't know about it.  I found out about it when an Atlantic City dealer took only one of my two chips on a losing bet and I had to ask why.
