Roulette is one of the most popular casino games in existence. It’s well-known by most people on Earth and also relatively simple.
I know that you will most likely be able to walk up to a roulette table and play the game without even reading about it. However, I believe proper preparation shouldn’t be neglected. If you want to play roulette (whether in a brick-and-mortar casino or online), you should know the basic roulette rules and the types of bets you can place in this game.
That’s why I put together this article. Think of it as a beginner’s guide to roulette that will teach you everything you need to know to have fun and maybe even win something while playing roulette. Keep reading and get ready for the game!
This article contains only the basics about roulette. If you already excel in your knowledge of the game, feel free to skip this article and move on to the roulette strategies that can help you increase your chances of leaving the casino with a win in your pocket.
Roulette rules
Roulette is a very simple game in its nature. It’s played using a roulette wheel that has 37 or 38 numbered and colored slots on it:
- European (French) roulette: numbers from 1 to 36 (red or black) and 0 (green)
- American (double zero) roulette: numbers from 1 to 36 (red or black), 0 and 00 (green)
A small ball is thrown into a spinning roulette wheel, and players bet on the number where they think the ball will land. Players can bet on an individual number or on many different groups of numbers. Bets on fewer numbers are less likely to win, however, award players with bigger wins. I will go through all of the possible bets, sizes of winnings and the probability of winning with different bets later on in this guide.
Apart from the ball and the wheel, there is also a roulette table with a layout used by players to place their bets. Bets can be placed before the dealer spins the wheel and throws in the ball. However, they can often also be placed even when the wheel and the ball are rotating, until the dealer announces that bets are closed.
The number the ball lands on is the winning number. All of the bets are then evaluated accordingly. The losing bets are collected by the dealer, while the winnings for the winning bets are paid out to the players.
Special roulette rules
Apart from the basic rules described above, there are some special roulette rules that change the way roulette is played, at least to some extent. The most used and well-known of these rules are:
- The rule “La Partage”
- The rule “En Prison”
- The rule “Surrender”
These special roulette rules are beneficial for the player, as they reduce the house edge and make the player lose less money in the long run. Therefore, if you have a choice, always choose a game with one of these rules in place.
The rule “La Partage”
“La Partage” applies to the so-called even chance bets (red/black, odd/even, 1-18/19-36) that have the same probability of winning and losing, and is used on many French roulette tables.
If a player places an even chance bet and the ball lands on 0, half of the wager is returned to the player.
The rule “En Prison”
“En Prison” is a more complicated variant of the “La Partage” rule. Here, instead of half of the bet being returned to the player, each even chance bet remains on the table after the ball has landed on 0. The dealer places a marker on it, which signalizes the bet is “in prison”.
The bet is then evaluated in the next round. If an “in prison” bet wins, the original wager is returned to the player. If not, the player loses it.
This means that the rules “La Partage” and “En Prison” bring more or less the same result in the long run, however, there is a small difference that is worth noting. Some players prefer “La Partage”, while others enjoy the added rush of “En Prison”.
The rule “Surrender”
While the two aforementioned rules are used for the French and European variants of roulette, the “Surrender” rule is used specifically in some American casinos as a part of their American roulette game.
It’s basically the same as the “La Partage” rule, but it applies to both 0 and 00. If the ball lands on one of these numbers, half of each even money outside bet is returned to the player.
California roulette rules
In the state of California, casino games in which outcomes are decided by balls or dice are banned. This outlaws the “normal” form of roulette, but casinos in California found a way to offer one of the most popular games of chance to their visitors. In Californian casinos, roulette is played with cards instead of the combination of a roulette wheel and a ball.
Players place bets pretty much the same way they would on a normal game of American roulette, but everything changes once the bets are closed. Instead of spinning a wheel and letting a ball “generate” the result, 38 cards identical to slots on an American roulette wheel are used. These are placed into an automatic card shuffler, and a randomly selected card represents the result of a roulette “spin”.
This is very much different than the three special rules mentioned above. The rules of California roulette don’t change the odds, but they are still worth noting. If you ever visit a casino in California, don’t be shocked, as Craps are played with cards, too.
Roulette etiquette
If you want to enjoy a game of roulette in a brick-and-mortar casino, you should also know how to behave at a roulette table, as well as what you should and shouldn’t do. That’s where roulette etiquette comes in. This part of the article will be especially helpful if you plan to play roulette in a big and fancy casino.
You can find the most important roulette etiquette “rules” in the list below:
- Know when to place bets. The dealer opens the betting round by saying “Place your bets!” From that point you are allowed to place your bets, until the dealer closes the betting round by saying “No more bets!”. You shouldn’t place any bets outside of this time window.
- Know when to cash chips and how to work with them. Roulette chips are quite different to chips for other casino games. In roulette, every player has chips of a unique color, so that he/she doesn’t mistake them for chips of other players. Roulette chips can’t be used for other casino games. Therefore, you should exchange money (or standard casino chips) for roulette chips when joining a roulette table and do the opposite when leaving it.
- Keep your excitement under control. It’s okay to be happy after a nice win, but you should be able to keep your emotions under control. No shouting, swearing or calling other people (the players or the dealer) names, neither when winning or losing.
- Help others place their bets or let them help you. Roulette tables can be quite big and some sectors of them might be hard to reach. If that’s the case for you, don’t throw the chips at the table. Instead, politely ask other players to put the chips on the table and explain exactly what bets you want to make. If it’s the other way around, don’t hesitate to help other players place their bets.
- Don’t drink too much. It’s okay to drink alcohol at a casino, but you should be able to keep it under control. Don’t get drunk. You might be impolite towards casino staff and other players, and you also might start making bad decisions.
- Follow the rules about tipping. Tipping is allowed in some casinos, while banned in others. Find out what the rules about tipping are in the casino you are in and follow them.
When playing roulette online, it’s not difficult to follow the roulette instructions. When playing a purely software based online roulette, you can’t really go against the rules. Live dealer roulette tables might be the only exception. In these games you can chat with the live dealer. Just be polite and everything will be fine. 🙂
Roulette bets and payouts
In roulette, there are many different types of roulette bets available. Players can bet on a single number or many different groups of numbers. The different types of bets allow players to place bets with a range of winning frequencies, as well as a range of differently sized wins.
Roulette bets are divided into three categories:
- Inside bets
- Outside bets
- Announced bets
The inside and outside bets are all the standard bets that every single player should know. The announced bets are a bit more advanced and not even available in every casino, so being familiar with them is certainly not a necessity when playing roulette on a basic level.
Inside bets
When you take a look at the roulette table layout, you will see that there are the numbers (1-36, 0 and 00 in the American roulette), as well as other sectors for bets. The inside bets are the ones that can be placed directly on the numbers themselves. You can find out more about them from the table below.

Announced bets (Call bets)
Announced bets (also sometimes called “call bets”) are a special type of bet that a player can announce to the dealer before they place the required amount of chips on the roulette table. These bets most commonly cover a specific section of the roulette wheel, which means that the numbers are not next to each other on the roulette table layout as they would be for a regular inside or outside roulette bet.
There is another way of placing announced bets apart from simply announcing them. On some roulette tables, there is a special area called a racetrack, which serves specifically this purpose. It’s basically a schema of the entire roulette wheel, with a special sector for each announced bet. Read more about the racetrack in my article about roulette table and wheel layout.
Third of the wheel (Le tiers du cylindre)
This bet covers 12 numbers from 27 to 33 (inclusive), specifically numbers 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16 and 33 on a single zero roulette wheel. While both of the previously mentioned bets cover the space on the roulette wheel around the number 0, the “Third of the wheel” bet’s coverage is located on the opposite side of the wheel.
Six chips (or multiples of six chips) are needed to place this bet. For a bet of six chips, the individual bets are placed on the following splits: 5-8, 10-11, 13-16, 23-24, 27-30, 33-36.
Neighbor bets
Neighbor bets (or neighbour bets in British English) are different to the aforementioned announced bets, because a neighbor bet can be applied to any number(s) on the roulette wheel.
A neighbor bet is a bet of five chips (or multiples of five chips) that covers any selected number and the four numbers closest to it on the roulette wheel (two on the left, two on the right). For a total bet of five chips, one chip is placed on each of the numbers straight up.
Final bets
A final bet is a bet on all numbers that end in a specific digit. A selected number of chips is placed on each of the numbers:
- Four chips (or multiples of four chips) are required to place one of the bets from “Final 0” to “Final 6”.
- Three chips (or multiples of three chips) are required to place one of the bets from “Final 7” to “Final 9”.
Third of the wheel (Le tiers du cylindre)
This bet covers 12 numbers from 27 to 33 (inclusive), specifically numbers 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16 and 33 on a single zero roulette wheel. While both of the previously mentioned bets cover the space on the roulette wheel around the number 0, the “Third of the wheel” bet’s coverage is located on the opposite side of the wheel.
Six chips (or multiples of six chips) are needed to place this bet. For a bet of six chips, the individual bets are placed on the following splits: 5-8, 10-11, 13-16, 23-24, 27-30, 33-36.
Neighbor bets
Neighbor bets (or neighbour bets in British English) are different to the aforementioned announced bets, because a neighbor bet can be applied to any number(s) on the roulette wheel.
A neighbor bet is a bet of five chips (or multiples of five chips) that covers any selected number and the four numbers closest to it on the roulette wheel (two on the left, two on the right). For a total bet of five chips, one chip is placed on each of the numbers straight up.
Final bets
A final bet is a bet on all numbers that end in a specific digit. A selected number of chips is placed on each of the numbers:
- Four chips (or multiples of four chips) are required to place one of the bets from “Final 0” to “Final 6”.
- Three chips (or multiples of three chips) are required to place one of the bets from “Final 7” to “Final 9”.
Complete bets (Maximum bets)
A complete bet (also called a ‘maximum bet’) is a bit more complex, because it contains many different kind of bets. The main idea behind these kind of bets is to maximize the total amount of inside bets that can be placed on any number.
That means that a bet called “17 to the maximum” takes 40 chips in total (1 chip being the maximum bet on a number straight up). These chips are placed on the roulette table like this:
- One chip on the number 17 straight up
- Two chips on each of the splits 14-17, 16-17, 17-18 and 17-20
- Three chips on the street 16-17-18
- Four chips on each of the corners 13-14-16-17, 14-15-17-18, 16-17-19-20 and 17-18-20-21
- Six chips on each of the “Six line” bets 13-14-15-16-17-18 and 16-17-18-19-20-21
If a player bets 40 chips like this and the roulette ball lands on the number 17, all of the bets win and the player achieves the highest possible winnings from a maximum bet (432 chips including his original bet, 392 chips net win). If the ball lands on some of the neighboring numbers on the roulette table layout, the player still wins something – just not nearly as much.
Roulette odds and probabilities
So, now you know all of the roulette bets, as well as how much you can win by placing them. Now, we are approaching the most interesting part of this article. It’s time to calculate roulette odds and find out the long-term value of each roulette bet.
I calculated so-called RTP (Return to Player) for each of the bets listed in the tables below. It’s also called the payout ratio. The payout ratio is the expected long-term value of a bet. Feel free to read more about it in my article about RTP and variance.
Inside bets – odds and probabilities
Everything you need to know about the odds of the inside roulette bets can be found in the table below. Some of the bets are only available in either American or European versions of the game, which is why some of the table cells are empty.

Announced bets – odds and probabilities
Announced bets are special. They consist of smaller bets that cover various sectors of the roulette table layout. That means the odds and probabilities of announced bets can be divided into the odds and probabilities of the individual smaller bets.
Therefore, I will not list the RTPs of these bets like I did for the standard inside and outside roulette bets. Any announced bet on single zero roulette has an RTP of 97.3 %. The announced bets I mentioned in this article only consist of inside bets, which means that the RTP of the total bet can’t be influenced by special roulette rules that change the RTP of the even chance bets.
Announced bets are almost exclusively used on European (French) roulette. However, if they were used (in a changed form) on American roulette, they would have an RTP of 94.74 %, unless they contained the “top line” bet which has a different RTP and would change the RTP of the total bet slightly.
Roulette house edge
House edge is the long term advantage the casino has over players. It can be easily calculated (for any game) as:
House edge = 100 % – RTP (Return to Player)
Therefore, the standard house edge for roulette is:
- European roulette (single zero roulette) – 2.7 %
- American roulette (double zero roulette) – 5.26 %
However, as you can probably tell after reading other parts of this article, there are some bets that are exceptions to this, as well as special roulette rules that can lower the casino’s advantage over players.
Here are the bets and rules that can change the house edge of the casino:
- The rules “La Partage” and “En Prison” decrease the single zero roulette house edge for even money bets (red/black, even/odd, high/low) to roughly 1.35 %.
- The rule “Surrender” decreases double zero roulette house edge for even money bets (red/black, even/odd, high/low) to roughly 2.6 %.
- The bet called “top line” that covers the numbers 0, 00, 1, 2 and 3 on a double zero roulette has the highest house edge found on a roulette table – 7.9 %.
The lower the house edge, the better off the players. From an RTP and house edge perspective, the even money bets on French roulette with either “La Partage” or “En Prison” rules are the most advantageous for the players, because they statistically lose only 1.35 % of their bets.
How does roulette house edge compare to other casino games?
Thanks to the house edge and RTP, it’s easy to compare various casino games and find out which of them are the least beneficial for the casino and the most beneficial for the player. So, is roulette’s house edge any good when compared to other games?
Here are the house edges of the most popular casino games:
- European roulette – 2.7 %
- American roulette – 5.26 %
- French roulette (with one of the rules “La Partage” and “En Prison”) – 1.35 %
- Blackjack (with basic strategy) – less than 0.5 %
- Slots – approximately 1 % to 8 % (roughly 4 % on average)
- Baccarat – approximately 1 % (when betting on Banker)
- Video Poker (Jacks or Better) – less than 0.5 %
As you can see, when it comes to table games, there are some games that are better for a player in the long run. American roulette is far worse for the player, which means that if you want to play roulette, try to find a casino that operates the single zero variant of this game, ideally using some of the rules that decrease the house edge in roulette.
How is roulette RTP and house edge calculated?
As I already mentioned, the game of roulette is relatively simple, which means that its RTP and house edge are quite easy to calculate. In this part of the article I will explain why the casino will always have an advantage in roulette, as this advantage is mathematically connected to the way this game works and to its odds.
For other bets, the expected value is the same:
- Expected value ($1 bet on red/black) = $2 * (18/37) = $36/37 = $0.973
- Expected value ($1 bet on a split) = $18 * (2/37) = $36/37 = $0.973
- Expected value ($1 bet on column) = $3 * (12/37) = $36/37 = $0.973
I could continue and write a calculation like this for every single possible European roulette bet, but it’s really not necessary. Payouts for every roulette bet are calculated according to the same formula, which means that every single European roulette bet has the same RTP of 97.3 % (the player statistically wins $0.973 for each $1 wagered).
For American roulette, the calculations are very similar. All that needs to be done is to substitute every number “37” in the calculations with the number “38”, as there are 38 possible outcomes of a double zero roulette game.
Every outcome of an American roulette game is a little bit less likely to occur than in European roulette (apart from “00” which can’t be found on the single zero roulette wheel), while the payouts remain the same. That’s precisely why American roulette has a worse RTP of 94.74 %.
The house edge can be easily calculated using the RTP like this:
House edge = 1 – RTP
Therefore, the roulette house edge is:
- House edge (European roulette) = 1 – 97.3 % = 2.7 %
- House edge (American roulette) = 1 – 94.74 % = 5.26 %
Conclusion
Roulette is not the game with the best odds in a casino, nor is it the one that can be the most thrilling to play. However, many would argue that roulette is the classiest table game you can find, which makes it a great experience to play.
What’s more, roulette is a game with a very simple set of rules and quite good odds for the player. It can be played even without an understanding of the concept of the game, although I believe that it’s always good to do some research and studying to grasp the basics and make good decisions while playing it.
That’s why I decided to write this article. I hope it helps you and I wish you good luck at the roulette tables, if you decide to try your luck at this game. If you want to play roulette online, I suggest picking a good casino from our list of roulette casinos or exploring dedicated roulette websites such as roulettevision.com.
