The Paroli system is merely the parley system that many gamblers use; that is, you increase your bet after a win and keep increasing your bet as the wins increase. Generally, a Paroli player will go three decisions before decreasing his bet to its original amount. So it would go $10, then a win and a $20 bet, then a win and a $40 bet. Then the winning bets are kept and the original $10 is wagered to begin a new series.
Neverminding the fact that roulette is definitely not a new game, roulette strategy is one of the most required things on the Internet. Although there are a lot of resources suggesting ways to beat a roulette table, all players should remember a phrase by one of the brightest men on the Earth, Albert Einstein - "You cannot beat a roulette table unless you steal money from it".

Play on European wheels instead of American wheels when possible. The American Roulette wheel has an extra slot, 00, which decreases the odds of winning. One pocket may not seem like a big deal, but the impact on probability is drastic. On an American wheel, the house advantage is twice that of a European wheel, which means you could lose money twice as fast.[8]
The “house edge” is what enables the casino to profit. An example is the European wheel has 37 pockets, but a 35-1 payout on single numbers. So if you win 1 in 37 as you’d expect with random bet selection, you’d be paid 35 units plus your original bet, leaving you with 36 units. But if roulette’s payouts were fair, you’d be left with 37 units after the 37 spins. Simply the house edge is unfair payouts. And it affects every bet and every roulette strategy. Even when you win, you are still getting paid unfairly.
Here’s why: the third column contains more red numbers than any other column, giving yourself a good chunk of red on the wheel. At the same time, you’re betting on black, which gives you a little under half the wheel. The third column has a payout of 2:1, and the black has a payout of 1:1, so your column bet should be half the black bet to break even. This is because if a red number shows up on the third column, you win double your bet, but lose your black bet, which is the same amount – it’s considered a push, since you’re even. It’s the same when a black number comes up: you win your black bet, but lose your column bet. But when a black number on the third column comes up, you pull ahead. This system of betting minimizes the risk while giving you a solid chance of steadily padding your bankroll.
Of course, casinos tend to frown on precise measurements and computer simulations by their gamblers, so the researchers developed a simpler method of predicting the outcome of a roulette game that could be deployed without notice. The first step is simply for a player to note the time it takes for the ball to pass a fixed point to get a rough approximation of the velocity of the ball. That approach, according to the researchers, produces results that " although noisy, are feasible" for making predictions.
Some French tables will employ rules that generally help out the players. The "La Partage" and "En Prison" rules apply to outside even money bets like odds or even, black or red and low or high; they also apply when the ball lands in the zero slot. They are similar in the sense that players only lose half of their bet, but players cannot leave their bet on the table for another spin with the La Partage rule. If a player loses, they can collect half their bet in the En Prison rule, or leave half their bet on the table for the next spin with the La Partage rule.

Casinos will normally post a maximum and a minimum stake for a roulette table and this is sometimes done for recreational play, too. Typically, for each spin of the wheel, if a player the total amount of a player's inside bets must exceed the minimum stake. The listed maximum stake usually shows only the maximum allowed for a single number "straight up" bet. The maximum stakes for other types of bet increases proportionately e.g. The maximum bet allowed for a pair of numbers is double the maximum straight-up bet, the maximum allowed for a corner bet is 4 times the straight up maximum and so on. So that really the limitation is on the amount that the casino can lose!
In addition to the 36 regular numbers, the American roulette wheel features two green slots that have 0 and 00 inscribed on them. They reside at the opposite side of the wheel, as do all consecutive and same color numbers. The distribution of regular numbers is also different from European Roulette, and this is how they go counterclockwise: 0, 2, 14, 35, 23, 4, 16, 33, 21, 6, 18, 31, 19, 8, 12, 29, 25, 10, 27, 00, 1, 13, 36, 24, 3, 15, 34, 22, 5, 17, 32, 20, 7, 11, 30, 26, 9, 28.
You have a better chance at winning when you bet on the "outside" side, which includes betting on a color, group of numbers, even or odd. Since almost half of the numbers are either black or red (except for the green that are 0 and 00) it's very close to 50% chance that you will win, being exact you have a 46.37% chance of winning. This also happens with even or odd and with the groups that includes numbers from 1 to 18 and 19 to 36. The closer you get to a specific bet the harder it gets to win. These probabilities up next are for the American Roulette: Black or red - 46.37%; Odd or even - 46.37%; 1 to 12 - 31.58%; Single Number - 2.63% (just to give some examples).
This is the most basic bet you can make in the game of roulette. You are betting on one particular number, and you can only win if that number is spun. If you bet that the number 13 is going to come out, you only win if the number 13 is rolled. As you can imagine, this is fairly tough to pull off. For that reason, though, you’ll get paid $35 for every $1 you bet when it hits. This bet is riskier but offers an enticing payoff.
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!
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.

 One of the most popular Roulette strategies, the Martingale system, is a fairly easy one to learn and replicate. The system itself is named after London casino owner John Henry Martindale, who encouraged players to double their bets after a loss. It works like this: simply place an even money bet, and if you lose, double your bet the next time round. If you win, place the exact same original bet on the next spin. Using this betting strategy will help you keep control of your bankroll, and while you may not win millions, you’ll be able to walk away with a healthy account balance – which most players would call a win in itself.
Roulette is a simple game to play as long as the players follow the rules. This section will explain how the game works and what general types of bets can be made. This chapter is the primer for the entire game including the “inside” bets and “ outside proposition” bets; how to buy into a game; the purpose of the scoreboards and why the concept of a Horse’s Ass reflects itself in some workers. I’ll also show you how the numbers around the American and European roulette wheels are ordered in such a way that they do not reflect the betting layout. Then I’ll explain how the casino builds its edge at both the American and European game by using two distinct methods.
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 note that you don’t have to guess the number exactly, but you can guess characteristics of the number and still get paid. For example, if you choose to bet that the number rolled will be odd, you will get paid if the number determined by the white ball is odd. It doesn’t matter to you if it’s 13 or 31; you will still get paid on your bet. 

On an American wheel, there are 38 spots: numbers 1-36, plus 0 and 00.  Your odds of winning a one-number bet are 37 to 1 (37 ways to lose, 1 way to win).  But if you win, the casino doesn't pay you 37 to 1, they pay you less: 35 to 1.  The difference between the true odds and what they actually pay you is 2/38, or 5.26%.  You can do this same calculation for the other bets, and it comes out the same.
