Roulette Probabilities

Roulette Probabilities

Roulette is a simple game played in most casinos, it contains a fixed set of probabilities with no real skill required to play the game.
In most parts of the world the roulette wheels have 36 numbers, one 0 and two 00, overall 38.
At the Europe wheel there are the same numbers, 1 through 36, but only a single 0.

Let’s have a look on the American Wheel:

We suppose you are betting on black. 18 of the 36 numbers of the roulette table are red and the other 18 are black. Only the 0 and 00 are green. On average, you will win 18 times out of 38, or your probability of winning is 18/38 = 9/19 = 0,474 which is slightly less than half.

Another typical 2:1 bet is to bet on a group of 12 numbers, you can do this by betting on a column of numbers. So overall you will win 12 times out of the 38 possible, for a probability of winning of 12/38 = 6/19 = 0,316.

You can calculate it for any other probability the same way. Just sum up how many of the results represent the win, and divide that by 38, on the European Wheel you divide it by 37. Multiply that value with 100 and you have the percentage.

If you only bet on a single number and the ball lands on that one, then you win with a ratio of 35 to 1. This happens once in 38 times / 37 times, but some people got very rich through this just having a lucky day.

Overall the house advantage is at around 5,2%, if you learn the betting strategies and tricks at roulette [link] you might be able to beat the bank almost daily!

  • Corner (or square): a bet on four numbers in a square layout (as in 11-12-14-15). The chip is placed at the horizontal and vertical intersection of the lines between the four numbers.
  • Six Line: a bet on two adjoining streets, with the chip placed at the corresponding intersection, as if in between where two street bets would be placed.
  • Trio: a bet on the intersecting point between 0, 1 and 2, or 00, 2 and 3.

Roulette History

The roulette was invented in China. Brought to Europe by traders, who were trading with the Chinese.
Several early versions of a wheel and spinning ball were invented in the 17th and 18th centuries in Europe. The first games that we would recognize as modern roulette were introduced in Paris casinos around the end of the 18th century. This game contained all of the features that we have today with the one exception, the single zero was red while the double zero was black. This led to some confusion for players and the color green was introduced for the zero and double zero to alleviate the confusion.

In the mid 19th century the single zero game was invented in France, this reduced the casino’s edge thereby increasing the odds of the player. When gambling was outlawed in Germany the inventor of the single zero machine (Louis Blanc) accepted an invitation to go to Monaco to establish and operate a casino. The casino set the standards for roulette in Europe, and roulette remained exclusive to Monte Carlo until 1933. This led to the gambling and resort industry in Monaco as many of Europe’s rich were attracted to the luxurious Monte Carlo casino.

The use of the double zero roulette wheels survived in the United States and is sometimes called the “American Wheel”. The introduction of the single zero wheel (with better odds for the player) resulted in the demise of the double zero wheels in Europe and has become known as the “French Wheel” in roulette history.

Roulette table layout can be named the most easily recognizable symbol of gambling in the entire world. Roulette table contains some typical parts, which can be found on the every roulette set. The long roulette table, which the player usually sees in the large casinos, can accommodate between six and eight roulette players quite easily.

On the table there is a layout containing the numbers that you can bet on. As you’ll learn in the roulette bets section, when you bet on a number, you’re basically betting that when the wheel is spun and the ball finishes its bounce, that it will come to its final rest on the number that you’d bet on.

For American roulette, the layout will contain thirty-eight numbers including a zero and a double zero. For European roulette, which is also called French roulette, the roulette table layout will contain thirty-seven numbers including a single zero. The picture shows an outline of an American Roulette table layout. The side and the end of the table that has the thick gray border is the section that’s fully dedicated to the players. They stand there to place their bets and observe the proceedings and in most cases, especially on a hot casino night, it’s standing room only at the roulette tables.

The end of the table is the dealer or croupier domain and only he/she may enter there. From there, the croupier spins the wheel, and calls the numbers, and is basically in charge of the roulette table proceedings. Online casinos of course it’s a whole different matter. In the world of online roulette, all you really need to know how to do is to use your mouse to place bets. Try it for yourself by playing on our own free virtual roulette game. No real cash involved, it’s all for fun, so try it out. If you want to try it with an online casino be aware their are only certain US accepted casinos.

European roulette has thirty-seven numbered slots including one for the number zero, while the American roulette wheel has thirty-eight numbered slots including two for the number zero (0 and 00).

Famous Bets

  • In 1873, the Englishman Joseph Jaggers made the first famous roulette biased wheel attack. Mr. Jaggers with a team of six clerks, clocked all the wheels at the Monte Carlo casino and found one wheel to show significant bias. In their attack exploiting this flaw they won over $325,000, an astronomical sum in 1873.
  • In the summer of 1891 at the Monte Carlo casino, a part-time swindler and petty crook from London named Charles Wells, broke the bank at each table he played over a period of several days. Breaking the bank meant he won all the available money in the table bank that day, and a black cloth would be placed over the table until the bank was replenished. In song and life he was celebrated as “The Man That Broke the Bank at Monte Carlo.” He later admitted that it was all luck, and he eventually ended up in jail for many years because of his fraudulent schemes.
  • In the 1942 film Casablanca, Rick’s Café Americain has a trick roulette wheel. The croupier can cause it to land on 22 at will. Rick (Humphrey Bogart) urges a Bulgarian refugee with whose case he becomes sympathetic to put his last three chips on 22 and motions to the croupier to let him win. After the man’s number dramatically comes up, Rick tells him to let it all ride on 22 and lets him win again. Although the details are not mentioned in the film (the croupier only notes that they are “a couple of thousand” down), it appears that Rick has given the man 3885 ((3*36*36)-3) francs.
  • Near the beginning of the 1973 film The Sting, Johnny Hooker (Robert Redford) takes his share of the money conned from a numbers runner and loses nearly all of it on a single bet against a rigged roulette wheel.
  • In the third part of the 1998 film Run, Lola, Run, Lola uses all her money to buy a 100-mark chip. (She is actually just short of 100 marks, but gains the sympathy of a casino employee who gives her the chip for what money she has.) She bets her single chip on 20 and wins. She lets her winnings ride on 20 and wins again, making her total winnings 129,600 marks (29,600 more than her smuggler boyfriend owed his boss, Ronnie). The odds of two consecutive wins on the same number on a European roulette wheel are exactly 1369-to-1 against.
  • In the South Park episode “Red Man’s Greed”, the town, facing destruction at the hands of Native Americans, bets $10,000 to raise money to save themselves. They win, but let it ride, and lose all of it.
  • In 2004, Ashley Revell of London sold all of his possessions, clothing included, and brought US$135,300 to the Plaza Hotel in Las Vegas and put it all on “Red” at the roulette table in a double-or-nothing bet. The ball landed on “Red 7” and Revell walked away with his net-worth doubled to $270,600.
  • In the music video for “Palace & Main” by Kent, guitarist Harri Mänty goes to Las Vegas and bets the entire video budget on black. He wins, and the profits were donated to charity.

Roulette Gambling Tipps and Tricks

One way win strategy: Try to start with small bets. When you win, boost the betting stepwise

Roulette online gaming tips

as you win risking only a calculated amount of your wins. Put no limit to winnings as long as profit is raising.

Set your target profit levels backwards: It is easier to fulfil a target level backwards (as profit recedes) than forward. The danger of forward profit targeting is that you can get close to it, and then lose the lot. Backward profit level targeting is more suitable on low risk/win ratio betting systems, so you risk a little to win a lot but you win fewer times. Thus when devising your system you should aim to win more money with fewer bets and in fewer winning spins, rounds, hands or cues. Positive stepwise betting is one way to achieve that. This is a more efficient way to bet and gives you more flexibility in managing your winnings.

Approach gambling realistic: You cant force a winning outcome and dont expect to win every time! Decide on a plan that lets you play in sessions or intervals, closing each session once certain criteria are met, and do not aim to win each one of them. What matters is the overall result.

Pocket winnings: Keep your winnings as you win and continue playing only with your principal bankroll. Once your principal bankroll is gone, count your pocketed winnings and continue playing only with half of any excess you have, that is, play with half of your net win (your winnings less your original bankroll). For example, if you start with 200 dollars, pocket winnings as you play and keep playing from your original amount. Once the 200 dollars are gone, if your pocketed winnings are $240, continue playing only with half the surplus, $20 (240-200=40/2=20).

Know when to stop: Before or during any game, tell yourself you are going to win and stay focused on the Task of winning your games. Just being positive will alter your winnings a little. And if you get hot or cold, dont get cocky or start to think everything is over for you. Just refresh and devise a good strategy that works for you personally. One that has been successful in the past will be in the future also. And most importantly, know when to stop, keep ur winnings.

Definition Roulette

Roulette is a casino and gambling game named after the French word meaning “small wheel”. In the game, players may choose to place bets on either a number, a range of numbers, the color red or black, or whether the number is odd or even. To determine the winning number and color, a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the circumference of the wheel. The ball eventually loses momentum and falls on to the wheel and into one of 37 (in European roulette) or 38 (in American roulette) colored and numbered pockets on the wheel.
