Roulette holds the crown for the most popular table game in online and offline casinos. This massive popularity is mainly propelled by the fact that it has been around longer than most, having been invented back in the sixteenth century. On top of its long-standing nature, the game is loved for the inclusion of roulette table odds, math, and probability in its gameplay, which makes it possible for punters to understand exactly how much risk they are taking with every stake that they place.

Review

The probability of winning in roulette depends on numerous factors, among them being the variation that is engaged. In the world of gambling, this game comes in multiple varieties that are dominated by two main versions – American and European Roulette. These variations are expounded on below:

American Roulette

This type, also known as Double Zero Roulette, was the very first variation of the table set to hit casino floors. This version is identified with thirty-eight pockets on the wheel, which are accounted for by the numbers one to thirty-six along with single and double zero pockets.

European Roulette

European Roulette came into the picture in the eighteenth century, which was two centuries after the invention of the American variation. Even so, the version was quick to overtake the original in terms of popularity due to the exclusion of the double zero that left it with thirty-seven pockets; hence, players could exploit a lower house edge and the best odds in roulette.

On top of these variations is that of French Roulette, which is especially popular in European gambling destinations. The version is much like the European one, but it includes the En Prison and La Partage rules in gameplay. The En Prison rule, which translates to In Prison in French, is activated when even money bets are placed. In case the ball lands in the zero pocket, one’s bet is withheld by the dealer, and the wheel is spun again. If the correct pocket is landed in the next round, the gambler gets their full wager back. With the La Partage rule, however, gamers only get half their stake back.

The Main Types of Bets in Roulette

Even with the different variations available in casinos, the types of stakes that can be placed remain the same in all of them. These wagers come in a wide array, but they are placed in two main categories for more straightforward classification. These bet types are:

Inside Bets

Inside bets are those that are placed on one number or a small group of numbers. For instance, if a gambler places a stake on the single number thirty-five, or two numbers that appear next to each other such as nineteen and four, they are termed as inside bets. These types of wagers cover single bets on up to six numbers, and they are termed as follows:

Bet on numbers Given name
One number Straight
Two numbers Split
Three numbers Street
Four numbers Corner
Five numbers Basket
Six numbers Double Street

Outside bets

Outside bets are the roulette stakes that hold large groups of numbers that go as high as eighteen of them. Like inside bets, they also have special terms used to refer to them in casino jargon, and they are as follows:

Bet on numbers  Given term
The first, second, or third set of twelve numbers out of the thirty-six Dozen
One of the three twelve-number columns on the roulette table Column
Red or black Color
Even or odd numbers Parity
First or last set of eighteen numbers High or Low

Odds and Payouts for Outside Bets

Outside bets cover large portions of the game wheel, which makes them carry better odds of winning. For instance, in the case of parity, colour, and High or Low stakes, punters have the winning European Roulette odds of 48.6% and 47.4% in the American version. Column and dozen bets, on the other hand, have winning odds of 32.4% in European Roulette and 31.6% in American Roulette. However, these payout odds in roulette are quite low, ranging between one to one and two to one.

Odds and Payouts for Inside Bets

Inside bets are quite hard to land considering they cover a small portion of the roulette wheel, and some of them are granted as follows:

  • Straight 

The Straight stake is the most challenging to come by, and it carries winning odds of 2.7% in the European version and 2.6% in the American one. The odds in roulette for these bets, however, are monumental, and they stand at thirty-five to one.

  • Split and Street Bets

The Split and Street wagers follow with payout odds of seventeen to one and eleven to one respectively. The lowest paying inside stake is Double Street, with payout roulette wheel odds of five to one. Even so, they have the highest winning odds of 16.2%, even though it does not compare to that of outside bets.

  • Corner
  • Double Street
  • Basket

Probabilities and Payouts of Called Bets

The roulette game also includes several other special bet categories referred to as called bets. These options carry stakes that are not provided in the conventional game table, and some of the most popular ones include:

  • Neighbour bets

The neighbour bets operate like big outside bets, but they cover the seventeen pockets that are close to the zero pocket. Usually, punters are not allowed to stake less than nine chips.

  • Zero Game

This option is similar to the neighbour bets, but only seven numbers are covered in the stake. The odds for this winning are quite impressive standing at 26:1.

  • Thirds of the Wheel
  • The Orphans

Winning Odds and Best Bets

You can see all the betting options on the game table. In short, you can bet on a single number, a series of numbers, a color or whether the result will be odd or even. Each option pays a different amount. Payment rates are based on probability calculations. The lower the likelihood of a choice, the higher the prize.

Instead of listing all the possibilities, let’s show you the odds that you are most likely to win at Europian roulette:

Type of the Bet Probability Payout
Odd/Even 48.6% 1 : 1
Red/Black 48.6% 1 : 1
1-18 / 19-36 48.6% 1 : 1
1 – 12 / 13 – 24 / 25 – 36 32.4% 2 : 1

The first three options should be the preference of everyone who wants a safe game. The odds are so high that you can be confident that you will win soon. Those who are willing to place risky bets should choose column and dozen options. At any rate, we recommend you stay away from single bets. The odd of a single number is only 2.6%.

Do not forget that this list represents the European version. In the American version, rates are on average decreasing by 2%. For this reason, always prefer the European version. Variants known as French roulette have the lowest house edge ratio and should be your first choice.

Wrap Up

Roulette stands among the simplest games to engage, but the inclusion of odds and probability in gameplay also allows the category to cater to skilled punters. Both free and real money versions of the set are widely accessible online.
