Roulette is a simple casino classic: you place a bet on where the ball will land on a spinning wheel. You can bet on a specific number, where the number will be odd or even, the color of the number, or a group of numbers. Once bets are placed, the dealer spins the wheel and the ball drops.

In this guide, we’ll walk you through the two main versions of roulette you’ll see being played at US casinos. You’ll learn to tell the difference between European and American roulette, what will give you better long term odds, and how to start playing at roulette at licensed and recommended real-money roulette casinos.

How to Play Roulette

Roulette is an iconic and instantly recognizable game on any casino floor. It often draws an engaged crowd due to its fast-paced nature and the easy rules and gameplay.

The basic aim of the game is to attempt to guess the number the ball will land on. The numbers on the roulette table correspond to the numbers on the roulette wheel. The two most common variations of roulette you will find at most casinos are:

In European roulette, the wheel contains 37 numbers from 0-36 which are color-coded in red and black with green for the 0.

In American roulette, the wheel has 38 numbers from 0-36 also in red and black but this version has an extra 00 green pocket. The numbers on the American roulette wheel are also arranged in a different order to European and other versions of roulette.

These rules and differences appear in both online and in physical casinos.

Understanding the Roulette Wheel

Roulette revolves around a spinning wheel with numbered slots or ‘pockets’. The dealer will take bets from gamblers before dropping the ball onto the spinning wheel.

Whichever players correctly guess the color, number or section the ball lands in, wins. In online roulette, the wheel and pocket the ball lands in are controlled by a Random Number Generator (RNG) mimicking the randomness of real-life roulette and ensuring game fairness to online players.

Placing Bets on the Roulette Table

With over 20 different types of bets available, betting on roulette is both varied and exciting. Inside and outside bets are the two main types of wagers; each one has its own range of varying payouts and odds, ranging from even money all the way up to 35:1.

Inside Bets

To break it down simply, inside bets are placed within or ‘inside’ the roulette table and include bet names such as street, corner, straight up and split. These types of bets are high payouts, long odds. This means you have a much lower chance of winning than with outside bets but the amount you win is much higher.

Outside Bets

Outside bets cover the rest of the roulette table, or the ‘outside’. They feature the more recognized bets such as red/black, odd/even, dozen and high/low. Since these are bets with low payouts, you probably won’t score huge wins with them. However, you will have higher chances of hitting than inside bets, so you can maintain your bankroll for longer.

Which Bets are Best?

There are no best bets in roulette; only good bets that work for you. If you're looking for a big win on a low budget, choose some inside bets and maintain your bankroll.

Roulette Game Variations

There are many different variations to roulette; some use more than one ball, others have more than one wheel and in some cases, the house edge can be less than the ‘regular’ variations so could see you winning more money in the long run.

Explore the different variations below, try them all out and discover a new favorite:

American Roulette

American roulette is one of the most popular versions of the game, played on a 38-pocket wheel numbered 1-36 plus 0 and 00. The extra 00 creates an extra pocket on the wheel which doesn’t exist on European roulette and increases the house edge to 5.26%.

This roulette variation offers unique five-number (or “top line”) bets on 0, 00, 1, 2, and 3. This option pays out at 6:1 but has a house edge of 7.89% and the worst odds on the table. The usual inside and outside bets we described above are also still available.

European Roulette

European roulette only has a single 0 on its wheel, making its house edge 2.7% - one of the lowest of all the roulette variants.

Players can also play with ‘call’ and ‘announced’ bets on the European table, ensuring fast and exciting gameplay online or in a physical casino.

Royal Roulette

Royal roulette has the same rules and format as European roulette, with the addition of a progressive jackpot bet. Alongside your main bet, you have the chance to make a second wager on either inside or outside bets, or singular numbers. To win the progressive jackpot bet, the number you choose must land five times in a row.

Multi-Ball Roulette

Using a European roulette wheel and table, multi-ball roulette adds as many as 10 balls at once. This increases the number of betting options players can make, making it an exciting and modern update to the classic roulette format.

French Roulette

French roulette uses the same single 0 wheel as European roulette and therefore has the same house edge. However, the French roulette table layout does differ slightly. In this game, the outside bets are split between the two long sides of the board. The bet types are the same as European roulette although of course in French; odd and even are ‘pair’ and ‘impair’, high bets are ‘passe’ and low bets are ‘manqué’.

Also on the board are 12 P (premiere douzaine), 12 M (moyenne douzaine) and 12 D (dernier douzaine). These refer to the 1st, 2nd and 3rd 12s (respectively) on the American or European roulette table.

French roulette includes the ‘En Prison’ rule, which means that your full stake is ‘imprisoned’ and carried over to your next spin if 0 hits on an even-money outside bet. If the next spin wins for that bet, you get your stake back (though with no profits), but you will lose the whole stake if the next bed loses. Another rule is ‘La Partage’, which means you immediately lose half your bet if the ball lands on an even-money outside bet. Some casinos offer a choice between these two rules.

Mini Roulette

Few online casinos offer this scaled-back version of roulette. Only half the size of a regular roulette table and with fewer betting options, it's a good game for new gamblers to practice their betting and wagering skills.

Multi-Wheel Roulette

Keep the fun going with multi-wheel roulette. This version of the game gives you even more chances of winning by playing with more than one wheel. The game also uses the same rules and set-up as European Roulette allowing you to bet on sections of the wheel and the table.

Live Dealer Roulette

Players can enjoy the energy and thrill of roulette games online in the comfort of their own homes. The house edge, bet types and rules will be the same in live dealer online roulette games as those in land-based casinos. While these appear less often on casino sites, the best online casinos for roulette will offer live dealer games.

Roulette Glossary of Terms

Whether you’re playing roulette online or in a physical casino, understanding the terminology used around the roulette table will allow you to keep track of the game and keep track of your bankroll.

Here, we’ve broken down some of the most common terms and phrases that you might hear while playing roulette:

Term Definition
Corner Bet This is an inside bet that can also be known as a square bet, box bet or quarter bet due to the shape the bet placement takes. If you place your chips on the position where four numbers meet, you'll have placed a corner bet.
Croupier This is another name for the dealer and is more commonly found in European casinos or when playing European or French roulette.
En Prison This rule can only be used while playing French roulette, however, it can be hard to find a casino or game that uses it. Essentially, if you have bet on any outside even money sections such as red/black, odd/even, high/low and the ball lands on 0, you have your initial wager ‘en prison’ or ‘in prison’ until the next spin of the wheel. If your original bet wins in the next round, you will get your entire wager returned in full.
Double Zero (00) The 00 is found only on American Roulette wheels and raises the house edge of the game to 5.26%. There are certain bets with American Roulette that allow you to bet on the 0, 00, 1, 2 and 3 of the roulette table.
High/Low High/Low is a type of outside bet. It refers to betting on the ball landing on the high end of the table (19-36) or the low end (1-18).
Inside Bets Inside bets are wagers you can make ‘inside’ the roulette table. You can choose from all the numbers; a single number, a set of numbers, a row, or even a whole chunk of numbers.
La Partage This rule is valid only when playing French roulette and in most cases is already in play with no action required by the player. If you have placed a wager on the outside even money sections such as red/black, odd/even, high/low and the ball lands on 0, all players will get half their wager returned.
Line Bet This bet can also be referred to as an avenue bet or a double street bet. Here, you bet on two adjoining rows of the table which amount to a total of six numbers.
Neighbors A called bet on one specific number, plus its immediate neighbors on the wheel. Usually this includes the two numbers on each side, so five numbers in total.
Voisons du Zero An announced bet that covers the section of the wheel around 0, usually this goes from 22 to 25 on a single-0 wheel, covering 17 numbers in total.
Odd/Even With this bet, you’re choosing if the ball will land on an odd number or an even number (excluding the 0 and/or 00).
Orphans/Orphelins This bet refers to the section of numbers that are not included in the voisins du zero or the tiers bet. This is more commonly seen on European and French roulette tables but can also be found on some double zero American roulette wheels too.
Outside Bets Wagers placed on the outside area of the roulette layout. These cover large groups of numbers, such as red/black, odd/even, high/low, dozens, or columns.
Pocket This is the name given to the individual numbered slots on the roulette wheel that the white ball falls into after a spin.
Red/Black Similar to odd/even, this outside bet allows you to bet on the ball landing on a red number or a black one.
Street Bet This inside bet allows you to bet on a ‘street’ by placing your chip(s) on the top of a three-number row on the roulette table.
Straight Up This is a bet on a single number on the roulette table. With a payout of 35:1, this is one of the highest paying inside bets available.
Thirds / Tiers This is a bet that can be made on the 12 numbers opposite the 0. Typically found on the European or French roulette table, you can also play it on certain double zero American roulette wheels too.
Zero (0) A single 0 can be found on all roulette wheels. European and French roulette both only have the single zero. American roulette has both 0 and 00, which increases the house edge to 5.26%.

The betting, the rounds and the odds and payouts for roulette in your own time, all without risking your own money.

What are the odds for online roulette?

The true odds in American roulette are 37:1 as there are 38 numbers on the roulette wheel. However, because of the house edge, the actual payout odds are 35:1.
