Roulette Odds Guide

The appeal of Roulette for players lies in the fact that it’s an easy game to understand and fun to play. Like most games of chance, there are no complicated rules which leaves straightforward gameplay.

What’s unique about roulette is that there are so many betting options, which means the odds of winning roulette are different for each one. If you want to play roulette online with a better understanding of the roulette wheel odds, this roulette odds payout guide will explain it all. I’ll explore how roulette odds work and vary according to bet type.

Roulette Odds Explained

The odds in any casino game refer to the likelihood of winning or the chances of a specific outcome occurring. For example, the odds of red or black in roulette refer to which colour the ball will land in, while the odds of a single number indicate the likelihood of the ball landing on that number.

The odds for either of these outcomes are different because of the roulette wheel structure. A single number occurs once on the wheel, but there are 18 red numbers on the wheel, which is why the odds of betting on colour are much higher. It’s important to keep roulette probabilities and odds in mind when playing roulette because it will help you choose your bets.

Roulette Wheel Odds

The roulette wheel is the most important part of the game because it produces the winning result. The standard wheel (European roulette wheel) has 37 red and black pockets, numbered zero to 36. The zero pocket is the only one that’s green in colour; the rest of the numbers are red or black in an alternating pattern.

The odds of the roulette wheel refer to how likely each possible result is expected to occur. As explained earlier, there are different odds on roulette numbers and other bet types like red or black, odd or even, outside bets, and so on.

Roulette Table Odds

The roulette table is another pivotal part of the game because it’s where roulette bets are placed. The chips are placed on the roulette table or betting board to indicate to the croupier what bets you want to play. In online roulette, virtual chips are used instead, but the process is the same.

The online roulette odds of the table are the same as the wheel odds for each bet. However, the roulette table odds in the European version differ from the American roulette wheel, as discussed in the following sections.

Roulette Odds by Game Version

The term ‘roulette odds’ refers to the chance of winning any bet in a roulette game. The odds on the American roulette wheel are lower than those on the European wheel because the former has a higher house edge.

There are three main versions of roulette: European, American, and French roulette. The difference between these versions is the type of wheel used. Although French roulette uses the European wheel, it has some different rules.

European Roulette Odds

The European version of the game offers the best odds in roulette because of the 37-pocket wheel. This wheel only has one zero, giving it a low house edge of around 2.70%. Compared to the American version, the European roulette odds are much more favourable.

You can use a roulette wheel odds calculator to determine the odds for each bet, but it’s also simple to calculate the odds yourself, which I’ll explain further in this guide.

American Roulette Odds

The main difference between European and American roulette odds is the addition of the double zero pocket in the latter. This gives the wheel an extra pocket which means it has 38 numbered slots with numbers ranging from one to 36. The zero and double zero pockets are both green.

Due to the extra pocket, the casino gets a bigger house edge. For each bet, there’s an extra non-winning outcome. For example, the probability of winning a bet on the number ’12’ in European roulette is 1/37, but in this version, it’s 1/38. In other words, American roulette doesn’t give you the best roulette odds, which is why it’s less popular than its European counterpart.

French Roulette Odds

French roulette is the third variant commonly found in online casinos and brick-and-mortar ones. This version is just as popular—if not more—than European roulette games. The same wheel with 37 pockets and a single zero is used in this game, which is why the roulette odds chart for this variant is the same.

However, the odds for even money bets are even better because the casino’s house edge is even lower due to special rules in this game. The La Partage and En Prison rules apply to losing even money bets and reduce the house edge to just 1.35%.

Roulette Odds by Bet Type

Roulette has many bet types that can be placed on the roulette table as separate bets or combinations. Bets in roulette can be split into two main categories: inside bets and outside bets. The third category is called bets, which are usually available on French roulette tables and sometimes in European games.

Inside Bets Odds

Inside bets in roulette are bets placed on a single number or a selection of numbers on the roulette table. These bets make up the interior part of the betting table and include straight bets, split bets, and six-number bets.

The roulette single number odds are the least favourable because they cover a few numbers. However, the payouts are quite high. This is true for all inside bets; the odds of winning are low, but the payouts are significant.

🎲 Inside Bets	✅ European Roulette Odds	✅ American Roulette Odds	✅ French Roulette Odds
👉 Straight Up Bets	2.70%	2.60%	2.70%
👉 Split Bets	5.40%	5.30%	5.40%
👉 Corner Bets	10.80%	10.50%	10.80%
👉 Street Bets	8.10%	7.90%	8.10%
👉 Six Line Bets	16.20%	15.80%	16.20%
👉 Basket Bets	N/A	13.20%	N/A
👉 Five-Number Bets	13.50%	13.20%	13.50%
👉 Trio Bets	8.11%	7.89%	8.11%
👉 Snake Bets	32.43%	31.58%	32.43%

Outside Bets Odds

Outside bets in roulette are the ones that make up the outer parts of the betting table. These cover at least 12 numbers and include betting on groups of numbers according to the colour, type, or section on the table.

Most outside bets are even money bets, which means they pay 1:1. The rest pay 2:1, which is rather low compared to the payouts that come with inside bets. However, as you can see from the table below, outside bets offer much higher odds.

🎲 Outside Bets	✅ European Roulette Odds	✅ American Roulette Odds	✅ French Roulette Odds
👉 Odd/Even	48.65%	47.37%	48.65%
👉 Red/Black	48.65%	47.37%	48.65%
👉 High/Low	48.65%	47.37%	48.65%
👉 18 Numbers	48.65%	47.37%	48.65%
👉 Dozen Bet	32.40%	31.60%	32.40%
👉 Column Bet	32.40%	32.40%	32.40%

Announced Bets Odds

Announced bets or ‘called bets‘, are types of bets usually called out to the dealer when playing in a real casino. The dealer must acknowledge the bet when you call it out rather than placing chips on the table like the previously described bets.

Announced bets are more complex because they cover specific sections on the wheel, and their odds aren’t always easy to calculate. Like outside bets, many offer relatively high winning odds but modest roulette payouts.

🎲 Announced Bets	✅ European Roulette Odds	✅ American Roulette Odds	✅ French Roulette Odds
👉 Neighbours of Zero	45.90%	N/A	45.90%
👉 Jeu Zero	18.90%	N/A	18.90%
👉 Thirds of the Wheel	32.40%	N/A	32.40%
👉 Orphans	21.60%	N/A	21.60%
👉 Final Straight	Depends on the numbers chosen	N/A	Depends on the numbers chosen
👉 Final Split	Depends on the numbers chosen	N/A	Depends on the numbers chosen
👉 The Neighbours	13.50%	N/A	13.50%

Learn How to Calculate Roulette Odds

The easiest way to calculate roulette odds is to use an online roulette odds calculator. However, you can also calculate the odds for each bet type yourself by following the step-by-step guide below:

1.  Choose a bet to calculate the odds for.
2. Next, determine the number of winning scenarios. For example, if you’re calculating the roulette number odds for one number, there’s only one winning scenario. If you want to bet on black, there are 18 winning scenarios.
3. Calculate the total number of outcomes. European roulette has 37 possible outcomes, while the American variant has 38.
4. Divide the number of winning outcomes by the total number of outcomes. This gives you the probability of winning that bet.
5. Multiply this number by 100 to change the probability to odds. Odds are always expressed as a percentage.
