Roulette Probabilities - One of the casino games with the best odds

Roulette is a classic table game whose origin dates back to the 17th century when this game was played in Italy. Even though roulette is commonly associated with France since the term means “wheel” in French, it was actually first played in the land of pizza and pasta. One of the reasons why roulette managed to stay so popular for so many years is its pretty low house edge. Furthermore, players have numerous betting options on the elegant roulette table as well as many odds that add a unique thrill every single game session. Roulette as a game can offer hours of entertainment and huge prizes, plus it suits players that want to take high risks just like it suits players that want to take it slow. All these features give roulette an irresistible charm that attracts a huge number of players wherever the game is offered. On our page readers will find all probabilities, strategies, systems and tips for the amazing game of roulette.

French Roulette Game Rules

French Roulette is a variant that is most commonly played in Europe. The reason why French Roulette is preferred by so many players is its low house edge, which is actually the lowest in comparison to other variants such as the European or the American one. Just like all other roulette games, French Roulette is played on a table which features the recognisable green roulette layout as well as a roulette wheel. French Roulette layout features numbers from 0-36 painted in red or black; the only exception is the zero field which is green. Additionally, the layout offers various betting opportunities such as black, red, odd and even fields that are next to the number area. The roulette wheel, on the other hand, consists of a rotatable disc with red and black slots on which all the numbers from the layout are written. Plus, there’s a small white ball that determines the winning number by landing in its slot once the wheel stops rotating.

Roulette has very extensive game rules and therefore we’ll only give you the general idea of how it’s played. The main objective of the game is to guess which number and/or colour will be the winning one by placing your bet on the appropriate field. For example, if you believe that 26 is going to be the winning number, you place your chips over the 26 field on the layout and wait for the outcome. The phases of the game are as it follows: placing bets, spinning the wheel, determining winning bets, removing losing bets, paying out and calling for bets for the next round. It has to be noted that when the dealer spins the wheel, he or she throws the ball in the opposite direction of the spinning of the wheel.

Chances at Winning on Roulette

European Roulette BowlMany roulette fans are worried when it comes to roulette probability, even though roulette probabilities are not even hard to calculate and follow. Roulette is a game of chance, completely unpredictable; each and every spin is unrelated to the spin before or the spin after. Therefore, even though the ratio of hitting black/red or odd/even in hundreds of days is stabilised at approximately 50:50, you can never be sure what the next outcome is going to be. For example, in one 100-session night there can be only 30 black hits and 70 red, whereas the next night the situation can be completely opposite. If you’re interested in finding out more about different roulette strategies and systems you can browse our site. When it comes to the game’s odds, they seem complicated because of the wide range of betting options. However, once you learn them, you’ll see how interesting game roulette is.

1. Simple Chance:

Simple chance bets, or better known as even paying bets, are the most popular among new players as well as among players that use progressive strategies. These bets have the highest odds of winning since they include 18 out of 37 numbers in total (zero included). By a simple calculation, you can see that the winning chance is almost 49% (48.6) and that’s the best one you can get on roulette tables. There are three different types of even paying bets and those are by colour, by type and by group. The payout for all this payout is even i.e. the players gets a prize exactly the same as the amount he or she wagered.

The first categorisation according to colour includes 18 numbers placed on black fields and 18 numbers placed on red fields. When players place their bet, they either place it on black or red; then they wait to see whether the ball lands in a black or red slot. Black and red slots are placed arbitrarily on the wheel, but the numbers printed on them are not in a correct order like 1, 2, 3 and etc. When placing a black/red bet it’s not important what the winning number is; the only thing that matters is the colour.

The second categorisation is according to number type i.e. odd or even. Similarly, the player places the bet on one of these two fields and waits to see whether the winning number is odd or even. There are 18 odd and 18 even numbers on the layout, thus the chances to hit either are equal. Again, it’s not important what number wins, but what type of a number it is. Therefore, if you bet on even you win regardless whether the winning number is 2, 12, 26 or 30.

The final types of even paying bets with 48.6% odds of winning are low and high. Low numbers are all numbers from 1-18, while high numbers are those from 19 to 36. On French Roulette the low numbers are also called Manque, whereas the high are called Passe. It’s interesting that unlike black/red and even/odd, low/high are not such popular bets among players even though they have exactly the same odds.

2. Dozen and Column Bets:

Simple Roulette ChancesBetting on one third of the numbers featured on the layout, instead of betting on half the numbers, is known as placing a dozen bet. These bets have lower chances of making you a winner, but, on the other hand, offer better payouts. You can bet that the winning number will belong in the first, second or third dozen i.e. 1-12 (Premier), 13-24 (Milieu) or 25-36 (Dernier). The payout rate for these bets is 2:1; that means that a winning £10 bet earns you a £20 prize.

Very similar to dozen bets are column bets. They also include 12 numbers each; these numbers are featured in column 34, column 35 or column 36. The payout and the winning odds are the same as the one offered on dozen bets. Both types are very popular among players because they include many winning combinations accompanied with a good payout rate.

3. Six Line

Six line bets include a total of six numbers that are featured in two consecutive horizontal lines. These bets are also called transversal bets and when a player wants to place such a bet he or she should point out the first and the last number of the bet. For example, betting on the numbers 1, 2, 3, 4, 5 and 6 should be announced like “Transversal 1-6.” Naturally, European layout features 37 numbers in total and since only six can earn the player a prize when a six line bet is placed, the chance of winning is pretty low 16.2%. Therefore, the payout is generous 5:1; this means that a £20 winning bet results with a £100 profit.

4. Corner

Besides betting on six consecutive numbers, you can bet on four numbers as well and this bet in roulette is known as corner bet. Because of the low chance of winning that equals 10.8%, corner bets have a lucrative payout of 8:1; bet £10, get £80. Sounds like a pretty good deal right? When placing this bet, players can’t simply choose any four numbers, but numbers that are neighbours on the layout. For example, such numbers are 8, 9, 11 and 12 or 19, 20, 22 and 23. Similarly like announcing six line bets, when corner bet is announced the lowest and the highest numbers are always mentioned.

5. Street and Basket

Obviously, the less numbers are included in a combination, the higher the payout is. Therefore, we came to the third best-paying bets on roulette and those are street and basket. Both of the bets include only three numbers. However, what makes basket special is the fact it has to include at least one of the zero fields. Therefore, if you’re playing on European layout, placing a basket bet means betting on 0, 1 and 2 or 0, 2 and 3. When playing on American layout you can choose between several combinations such as 0, 00 and 2 or 00, 2 and 3. Street bet, on the other hand, includes any three horizontal numbers like 1, 2 and 3 or 13, 14 and 15. The payout for these two bets is high 11:1, while the odds of winning are 8.1%.

6. Split Bet

Just like the name suggests, this bet is split on two neighbouring numbers, It doesn’t really matter whether the numbers are next to each other or one above the other; thus, you can bet on 16 and 17 as well as on 16 and 19. The payout offered to those that place split bets is 17:1 and it’s the second best paying bet offered on the game. Naturally, the chances of winning a split bet are pretty low 5.4%. However, it’s amazing to win £170 with a £10 bet, isn’t it?

7. Straight Up

Well, the last betting option on the inside area of the layout (area with the numbers) is wagering on a single number. This type of bet is commonly known as straight, straight up and plein. The risk of trying to guess the exact number is very high and therefore the odds of winning are low 2.7%; the player tries to guess a single number out of 37 in total (on European layout). Nevertheless, the reward is high and thus if a player places a winning straight bet he or she will profit 35 times the initial bet amount. In other words, a £10 bet can bring you a £350 profit.

The Zero on Roulette

Roulette House Edge through the ZeroEven though the zero field on roulette seems not as important as the other numbers, it actually has a very special role. Often unnoticed by players, the zero is what makes roulette house edge so high because it adds one extra number and colour that affect all betting options. Because of the zero the winning odds of the even bets, for example, are not 50-50 and the single bet’s odds are not 36:1, but 37:1. The zero decreases players’ chances of hitting a winning combination and makes roulette less favourable towards players.

However, the zero is not present only to build up the house edge of the game. Players can actually bet on this number and win a good prize with payout 37:1. Also, sometimes the zero means a second chance for players if the game is played with the La Partage rule. Namely, all bets are lost when the ball lands on zero. The only exception is French Roulette played with La Partage or En Prison rules that allow players to either keep 50% of their bet or leave it on the table for another round.

Betting in Accordance with the Roulette Wheel

Odds of the betting optionsBasic roulette bets and betting opportunities are formed in accordance with the layout. However, experts know that another way of placing bets is by taking into account the numbers’ setting on the roulette wheel. Noticing this, some game developers have even made separate fields on the layout to make it easier for players to place such bets. As we have already mentioned, the numbers on the wheel are not arranged in the correct order and that opens various opportunities to players such as bet on wheel neighbouring numbers, large series, small series, orphans and etc. Find out more about each of these options that many times proved profitable for players.

1. Wheel Neighbours (Voisins)

Just like there are neighbours on the layout, there are neighbours on the wheel as well. When announcing such bets players have to state the central number and then the number of neighbours on either side of the wheel. For example, if you place a bet on 28 with two neighbours, you’re actually betting on 29, 7, 28, 12 and 35. The winning odds as well as the payout rate always depend on the exact number of fields included in the bet. In the situation explained above the player bets on five numbers in total and thus the chance of winning is 13.5%.

2. Zero Game (Jeu 0)

Another popular way of betting on the roulette wheel is placing four bets on zero and six numbers around it. Such game is known as zero game and includes four different types of bets, seven numbers in total and 18.92% chances to win. Split bets are placed on three pairs of the numbers, while one number gets a single bet. The winning amount, in case the ball lands in one of your slots, depends on the type of bet placed over that number.

3. Large Series (Voisins du Zero)

Stakes Roulette SeriesEven though rarely played, large scale made of 17 numbers in total is another betting option to roulette players. Large scale takes nine chips at least; two chips on two corners and one chip on five splits. However, the payout for guessing one of the mentioned combinations is not that big compared to the invested amount; hence the low popularity of the bet.

4. Small Series(Tiers du Cylindre)

Small series is the second part of the large series and therefore includes 12 numbers. A total of six chips are used for completing the small series. This bet is also called the Tiers and includes six split bets; the splits are 5/8, 10/11, 13/16, 23/24, 27/30 and 33/36.

5. Orphans (Les Orphelins)

There are eight numbers on the wheel that are not included in any of the combinations and those numbers are called orphans. Les orphellines, as the French call them, make two slices of the wheel between the Tiers du Cylindre and the Voisins du Zero. Those numbers are 1, 20, 14, 31, 9, 17, 34 and 6. Playing the orphans can be made with either eight or five chips, depending on the combinations you want to use.

Other Popular Roulette Bets

We mentioned that one of the top reasons why roulette is such a popular game, which can rarely become boring, is the fact it has numerous betting options. We already explained a good deal of bets that players can place on roulette tables, but don’t be fooled that those were the only one. Finals and Chevaux-finals are two other types of bets preferred by experienced gamblers.

1. Finals

Did you know that many people pick a number from one to nine as their favourite number? Usually, when someone has a favourite number, not only he or she gambles on it, but also on two-digit numbers that end on it. For example, if your lucky number is four, the chances that you’ll want to bet on 14, 24 and 34 are very high. Such bets are called finals because they’re determined by their final number. The number of chips needed for completing a final is either four or three, depending on the number. The chances to win are determined by the number of bets placed, whereas the payout is calculated as it follows: straight up bet payout minus the losing bets.

2. Chevaux-finals

Chevaux-finals are combinations of two standard finals and require a three chip investment. Unlike the standard finals where the bets are straight ups, here the bets are splits. Therefore, a player can complete the 2 finals and 5 finals by placing split bets on 2/5, 22/25 and 32/35. This type of bet covers six numbers out of 37 and thus has odds of winning of 16.2%. The payout is 17:1, but from the winning amount you have to take out the losing chips in order to calculate the exact profit.

American Roulette

American Roulette with two ZerosAmerican Roulette is a game similar to French Roulette. It’s played on a roulette table and it features a layout and wheel too. However, the crucial difference is in the additional green double zero field that drastically increases its house edge and thus makes it unfavourable towards players. Some other minor differences between American and French Roulette are the table size and the way of pronouncing the winning number. On French Roulette the table is bigger, while American Roulette is usually played on a smaller table. Furthermore, when a winning number is revealed on French Roulette, it’s displayed with the help of the Rateau. On the other hand, croupiers that host American Roulette tables use a Dolly, which is a small metal figure.

Probabilities in American Roulette

The house edge of French Roulette is 1.35% if the game is played with the La Partage rule. European Roulette, which is traditionally played without that rule, has a doubled house edge of 2.70%. American Roulette has even higher house edge of 5.26% because of the additional field. Therefore, it’s usually said that this variant is the worst; even though that’s not true since Mini Roulette has even worse house edge. Nevertheless, players must have this in mind when deciding what game to try. Naturally, the thrill might be bigger when playing a game that is less favourable towards you; however, the risk is bigger as well.

1. Even Paying Bets

Even paying bets such on American Roulette as red/black, odd/even and high/low include exactly the same numbers as French Roulette. The only difference here is that instead of betting on 18 numbers/fields out of 37, you’re betting on 18 out of 38. Therefore, the chances to win are lower and the house edge is higher.

2. Dozens and Columns

Just like there are dozen and column bets on French and European Roulette, players of American Roulette can place dozen and column bets too. Once again, the numbers featured in the dozens and columns are the same; for example, the first dozen is 1-12, while the first column includes all numbers in line with 34. Not surprisingly, the house edge of this bet on American Roulette is higher than the one found on French Roulette and the chances to win are 31.58%. The payout rate is the same nonetheless. Thus, a £10 bet earns players a £20 profit.

3. Straight Up

Obviously, straight up is another betting option offered on all roulette games, American included. There are 38 numbers in total and the players try to guess only one. This means that this bet has even worse odds than straight up bets on French Roulette. Plus, the lower chances to win don’t affect the payout, which is exactly the same as the one on the French variant i.e. 35:1.

The Zeros on American Roulette

Doublezero at the American RouletteWell, we mentioned more than once that there are not one, but two zero fields on American Roulette. They are located on opposite sides of the wheel to each other. Both fields are green, but one of them features two zeros instead of one. This field almost doubles the house edge and increases players’ chances of losing. If the ball lands on either of these two zero fields, they lose their bet if it’s placed on any other field. The American version of the game still has 18 red numbers and 18 black numbers. It is simply the inclusion of an extra zero on the wheel which makes American Roulette less favourable to players in the long run.

Memory of the Roulette Ball

The Roulette Ball in useIt’s crucial to remember that roulette, any variant, is a completely random and unpredictable game. Many players make the mistake of believing that if the ball landed in black slots several times in a row, it will certainly land in a red one very soon. This belief is known among players as the “Memory of the ball” and it’s completely untrue. Nobody can guarantee that the ball will land on red, odd, high and etc. There can be 10 or 20 sessions when it lands on same colour or even number, just like there can be 10 or 20 sessions when it lands on a different colour each spin. Therefore, you should avoid the Roulette Coups strategy since it can cost you lots of money.

Roulette Compared to Other Table Games

Depending on the selected roulette variant, this game’s house edge can vary from 1.35% to 5.26%. Knowing this, we can easily compare the classic game to other commonly played table games and see whether there are better options than roulette. Baccarat is a game with pretty low house edge of 1.06% on the banker bet, whereas the player bet comes with a 1.25% house edge. Thus, regardless what bet you place, you’re still in a better position than playing roulette. Craps has bets whose house edge is extremely high, but also bets with zero house edge. Therefore, it can be both a better and a worse option than roulette. Finally, another game with low house edge is blackjack played under liberal rules. This variant has a low favourability towards the house of 0.28%.

To sum up, there are some games with a better house edge than roulette. Nevertheless, roulette offers many betting opportunities, good payouts and thrill that can’t be found on any other casino game. Therefore, it’s far from a surprise to see it survive for so many years and staying one of the top picks in land based as well as at online casinos.

‘… Roulette remains one of the most popular casino games. With 97.3% of bets paid out as winnings, it is also considered to be one of the most favourable games.’ – Quote – ICRT (International Consumer Research & Testing)
