The Complete Guide to Roulette Odds

Here follows a comprehensive guide to Roulette odds and the steps to improve them so your Mobile Live Roulette experience only gets better.

The Complete Guide to Roulette Odds

Introduction to Odds

Being a game of chance, Roulette is entirely reliant on odds. Your odds of winning by betting on any number are 37 to 1 since there are 37 numbers on the typical Roulette wheel. However, the reward you get from the house upon winning is only 35 to 1. This gives the house a fairly big edge in Live Roulette Games.

There are different types of bets you can place in Roulette, and the odds vary considerably according to the variation you’ve chosen to play.

For example, European Roulette has only one ‘zero’ on the wheel and therefore, offers better odds to the player than American Roulette. Interestingly, however, when Roulette originated in France, the wheel had two ‘zeroes’ in it and the same was carried over to the US. But when the Monte Carlo casino switched to one ‘zero’, all European casinos followed suit and the version came to be called European Roulette. You’ll also find Live Roulette variations in the way top casinos offer their services — they differ in the game providers available, website user interface, Live Roulette bonuses offered, and more.

As stated earlier, Roulette’s odds also change according to the bet type. Let’s explore the different types of bets and associated odds you’ll come across in live casinos.

Types of Bets

Roulette has mainly two types of bets — Outside Bets and Inside Bets. They are named so because of their positions on the layout on the table. Here’s a quick summary before we dive into the details.

Types Of Bets Payout Ratio American Roulette Odds American Roulette House Edge European Roulette Odds European Roulette House Edge
Reds / Blacks 1:1 47.37% 5.26% 48.65% 2.7%

Straight 35:1 2.63% 5.26% 2.70% 2.7%

1. Outside Bets

Outside bets have higher odds of winning, which is why people who choose them prefer to play it safe. Their only caveat is that the payouts are minimal because of the high win probability. The most common and popular Outside Bets are the ‘even-money’ bets. They cover almost half of all possible outcomes; the number ’zero’ in European Roulette and the ‘double zero’ is excluded in American Roulette. You’ll find three options in even bets in Roulette: red or black, even or odd, and 1-18 or 19-36.

Even-money bets have a measly payout of 1 to 1 because of their high win probability. To go into the details, they have a winning chance of 48.65% in European Roulette and 47.35% in American Roulette.

The other outside bets are Column and Dozen, each of which covers 12 numbers on the layout. You can bet on the first, second, or third column of numbers or the first, second or third dozen of numbers (1-12, 13-24, 25-36). These cover approximately one-third of the total outcomes and so offer better odds than even-money bets. Column and Dozen have winning chances of 32.43% for European Roulette and 31.58% for American Roulette and consequently offer a payout of 2 to 1.

2. Inside Bets

While placing an Inside Bet, you bet on a single number or a small group of numbers. They have significantly lower winning probabilities and much better payouts. You can group your numbers in the following ways.

  • Straight

    Betting on a single number is called a straight bet or a single-number bet. It has the lowest winning odds and the highest payout of all — 35 to 1. The precise chance of the ball landing in your favourable pocket is 2.70% in European Roulette and 2.63% in American Roulette.

  • Split

    You can pick any of the two numbers on the table on the condition that those numbers are neighbours on the table. You’ll get a payout of 17 to 1 for a winning percentage of 5.41% in European Roulette and 5.26% in American Roulette.

  • Street

    You can also choose to bet on a group of three numbers that are in chronological order, like 1, 2, and 3. The payout that accompanies this bet type is 11 to 1 with a success probability of 10.81% and 10.53% in European and American Roulette respectively.

  • Corner

    You need to bet on four numbers that are in the form of a square on the table. You’ll get a payout of 8 to 1 for a win probability of 10.81% and 10.53% for European and American Roulette respectively.

  • Double Street

    In a street, you bet on a row of numbers; in a double street, you bet on two rows of numbers, that is a total of six numbers. For a win probability of 16.22% for European Roulette and 15.79% for American Roulette, you get a payout of 5 to 1.

  • Basket

    Also called a ‘five-number bet’, this bet type allows you to bet on zero, double zero, 1, 2, and 3. You can only find this in American Roulette (winning probability of 13.16%) and offers a payout of 6 to 1.

3. Called Bets


Called bets are exclusive to European/French Roulette, and are also called as ‘Announced Bets’. In this type of bets, you can bet on numbers combined according to their positions on the Roulette wheel, not the table layout. Called bets are classified into two types — Fixed bets and Variable bets. Fixed bets are as follows:

  • Neighbours of zero

    You need to place at least 9 chips to cover the 17 numbers on the wheel that is close to the green zero. The winning odds come up to a staggering 45.9% and you can get a payout as high as 24 to 1 depending on the winning number.

  • Zero game

    This is a smaller version of ‘Neighbours of Zero’ and covers only 7 numbers close to the green zero. Payouts can reach up to 26 to 1 and the winning odds are 18.9%.

  • Thirds of the wheel

    You can bet on the 12 numbers that are situated directly across the ‘Neighbours of Zero’ numbers. You’ll get a payout of 17 to 1 for a winning probability of 32.4%.

  • The orphans

    This type lets you bet on any of the numbers that are not included in the called bets listed so far. They offer a winning probability of 21.6% and a payout of 26 to 1.

Variable bets are also of two types — the neighbours and the finals. In the former type, you can bet on any of the five neighbouring numbers, while for the latter, you have to bet on the last digit.

4. En Prison and La Partage bets

European Roulette House Edge
WITHOUT La Partage and En Prison 2.7%
WITH La Partage and En Prison 1.35%

These bets are also common to European/French Roulette. In fact, the La Partage rule is a default offering in most French casinos. En Prison is harder to find but is much more beneficial for the players.

  • La Partage

La Partage translates to ‘the divide’ in French and divide is exactly what it does. So when you place an even-money bet and the ball lands on ‘zero’, the dealer splits your bet amount in half, gives you back apart and keeps the other for themselves. This rule cuts the house edge in half from 2.70% to 1.35%.

  • En Prison

In this rule, when the player makes an even-money bet and the ball lands on the ‘zero’, the dealer places a marker on the bet indicating that it’s ‘in prison’. The wheel is spun again and the new outcome determines the winner or loser.

How to Improve your Roulette odds?

Now that you’ve understood the basic gameplay and terminology of Roulette, you can take advantage of this knowledge to improve your Roulette odds in many ways.

  • Memorise the odds

There is a wide variety of bets that you can place in Roulette and you need to know the odds associated with any bets you’re placing. While we’ve mentioned all the odds above, committing them to memory will help you make the most of your bankroll.

  • Pick the best variant

There are a lot of Roulette variants out there. All of them are fun but it’s important to find the one that’ll have the lowest house edge. We suggest that you play European Roulette and try to find casinos that have the La Partage and the En Prison rules.

  • Play safe

If you want to have fun without hurting your bankroll, it’s best to play safe. Outside bets pay out more frequently and ensure high win percentages. So stick to a table’s minimum bet and place two equal outside bets.

Armed with the extensive knowledge of Roulette odds and how to improve them, you’re now ready to take on the world of gambling by storm, or at least not look like a fool at the table. Have fun!
