The Basics of Roulette Wheel Numbers
Roulette wheel numbers form the foundation of this popular casino game, with slight variations depending on the version being played. Understanding these differences is crucial for players looking to improve their odds and develop effective betting strategies.
European vs American Wheels
The main difference between European and American roulette wheels lies in their layout and the number of pockets. European roulette wheels feature a single zero (0), while American roulette wheels have an additional double zero (00) pocket 1 2. This seemingly small variation has a significant impact on the game's dynamics and the house edge.
The presence of the extra 00 on the American wheel results in a higher house edge compared to its European counterpart. In fact, the house edge in American roulette is almost double that of European roulette 1. This means that, over time, players are likely to lose more money playing American roulette than European roulette.
It's worth noting that the addition of the 00 pocket in American roulette isn't simply inserted into the existing European wheel layout. The order of numbers on both wheels is completely different 1. This variation in number sequence adds another layer of complexity to the game.
Number of Pockets
The number of pockets on a roulette wheel is a key factor in understanding the game's odds and probabilities.

American Roulette:
This difference in the number of pockets directly affects the probability of winning and the house edge. The house edge for European roulette is 2.7%, while for American roulette, it increases to 5.26% 4.
Colour Distribution
Both European and American roulette wheels follow a specific pattern in terms of colour distribution:
-
Alternating colours: The numbers on the wheel alternate between red and black, creating a visually balanced appearance 4.
-
Green pockets: The zero (0) in European roulette and both the zero (0) and double zero (00) in American roulette are coloured green 2 3.
-
Low and high numbers: On the European wheel, low (1-18) and high (19-36) numbers alternate as much as possible 4.
-
Odd and even distribution: Both wheels ensure that odd and even numbers are evenly distributed, with no more than two consecutive odd or even numbers adjacent to each other 4.
The sequence of numbers on both wheels may appear random, but it's carefully designed to achieve several objectives:
- To confuse players and prevent easy prediction of where the ball might land.
- To maintain a balance between red and black numbers.
- To distribute low and high numbers evenly (especially in European roulette).
- To ensure a fair distribution of odd and even numbers 4.
While both wheels are designed with these principles in mind, many consider the European roulette wheel to be more balanced due to its more even distribution of low and high numbers 4.
Understanding these basics of roulette wheel numbers provides players with valuable insights into the game's mechanics and probabilities. Whether playing European or American roulette, knowledge of the wheel layout, number of pockets, and colour distribution can help inform betting decisions and strategies.
European Roulette Wheel Layout
The European roulette wheel has become a standard in casinos worldwide, known for its single zero pocket and favourable odds for players. This variant features 37 pockets, including numbers from 1 to 36 and a single green zero 1. The layout of the European wheel has been carefully designed to create a balanced and unpredictable game.
Number Sequence
The sequence of numbers on a European roulette wheel may appear random at first glance, but it follows a specific pattern designed to maintain balance and fairness. The numbers are arranged as follows:
0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26 2
This arrangement ensures that:
- Red and black numbers alternate around the wheel.
- Low (1-18) and high (19-36) numbers are distributed as evenly as possible.
- Odd and even numbers are balanced, with no more than two consecutive odd or even numbers adjacent to each other 2.
An interesting fact about the European roulette wheel is that the sum of all numbers equals 666 3.
Sector Bets
The European roulette wheel layout allows for unique betting options known as sector bets or announced bets. These bets cover specific sections of the wheel and are popular among experienced players. Some common sector bets include:
-
Voisins du Zéro (Neighbours of Zero): This bet covers 17 numbers surrounding the zero on the wheel, from 22 to 25. It requires nine chips to place 4.
-
Jeu Zéro (Zero Game): A smaller version of Voisins du Zéro, covering seven numbers (12, 35, 3, 26, 0, 32, 15) with four chips .
-
Tiers du Cylindre (Thirds of the Wheel): This bet covers 12 numbers on the opposite side of the wheel from the Voisins du Zéro, using six chips .
-
Orphelins (Orphans): This bet covers the remaining eight numbers not included in the Voisins du Zéro or Tiers du Cylindre bets, using five chips .
-
Neighbours: This bet covers five consecutive numbers on the wheel, with the player indicating the middle number "and its neighbours" .
These sector bets add an extra layer of excitement and strategy to the game, allowing players to cover large sections of the wheel with a single wager.
House Edge
The house edge in European roulette is significantly lower than its American counterpart, making it a more attractive option for players. The single zero on the European wheel results in a house edge of 2.7% 1. This means that, on average, for every £100 wagered, the player can expect to lose £2.70 over the long run.
To put this into perspective, let's compare the house edge of different roulette variants:
| Roulette Variant | House Edge |
|---|---|
| American Roulette | 5.26% |
| European Roulette | 2.70% |
| European Roulette (En Prison/La Partage) | 1.35% |
The lower house edge in European roulette is due to the absence of the double zero (00) found in American roulette. This single difference nearly halves the casino's advantage, making European roulette a more player-friendly option 1.
Understanding the European roulette wheel layout, its number sequence, sector bets, and house edge can help players make more informed decisions and potentially improve their chances of winning. However, it's important to remember that roulette remains a game of chance, and no strategy can guarantee consistent wins.
American Roulette Wheel Layout
American roulette, a variant less commonly found in casinos outside the United States, features a distinct wheel layout that sets it apart from its European counterpart. This version of the game has a significant impact on the odds and gameplay experience for players.
Double Zero
The most notable feature of the American roulette wheel is the presence of an additional pocket: the double zero (00). This wheel has a total of 38 pockets, including numbers from 1 to 36, a single green "zero" pocket, and the extra green "double zero" pocket 1. The inclusion of this additional pocket has a profound effect on the game's dynamics and the house advantage.
The 0 and 00 pockets are strategically placed on opposite sides of the wheel 2. This placement ensures that these green pockets are evenly distributed, maintaining the wheel's balance while maximising the house's edge. The green colour of these pockets distinguishes them from the alternating red and black of the numbered pockets, making them easily identifiable to players and croupiers alike.
Number Sequence
The sequence of numbers on an American roulette wheel follows a specific pattern designed to create a balanced and unpredictable game. The numbers are arranged in a clockwise manner, with the following sequence:
0, 28, 9, 26, 30, 11, 7, 20, 32, 17, 5, 22, 34, 15, 3, 24, 36, 13, 1, 00, 27, 10, 25, 29, 12, 8, 19, 31, 18, 6, 21, 33, 16, 4, 23, 35, 14, 2 3
This arrangement ensures that:
- Red and black numbers alternate around the wheel.
- Low (1-18) and high (19-36) numbers are distributed as evenly as possible.
- Odd and even numbers are balanced, with no more than two consecutive odd or even numbers adjacent to each other.
The American roulette wheel layout also adheres to certain principles:
- There are no adjacent numbers of the same colour 2.
- Consecutive numbers are placed on opposite sides of the wheel 2.
- The sum of any two adjacent numbers on the wheel is always an odd number.
These design features contribute to the game's unpredictability and fairness, making it challenging for players to identify patterns or predict where the ball might land.
House Edge Comparison
The inclusion of the double zero pocket in American roulette significantly impacts the house edge, making it less favourable for players compared to European roulette. This difference in house edge is a crucial factor for players to consider when choosing which version of roulette to play.
The house edge for different roulette variants is as follows:
| Roulette Variant | House Edge |
|---|---|
| American Roulette | 5.26% |
| European Roulette | 2.7% |
To illustrate the impact of this difference, let's consider a simple betting scenario:
Suppose a player places £7.86 on red and £7.86 on black, for a total bet of £15.71. In European roulette, with 37 pockets (including one green zero), the player will win back their £15.71 bet 36/37 times when the result is red or black. They will lose their entire bet only 1/37 times when the ball lands on the green 0 4.
In American roulette, however, there are 38 pockets (including two green numbers). The player will still win back their £15.71 bet when the ball lands on red or black, but now they have two opportunities to lose their entire bet: when the ball lands on either 0 or 00. This increases the probability of losing to 2/38 4.
The presence of the double zero nearly doubles the house edge in American roulette compared to European roulette. This significant difference in house advantage has led many players to prefer European roulette when given the choice between the two variants.
Despite the higher house edge, American roulette remains popular in many casinos, particularly in the United States. Some players may choose this variant due to familiarity or personal preference, while others might not have access to European roulette tables in their local casinos .
French Roulette Wheel Layout
French roulette shares many similarities with its European counterpart, featuring the same wheel design with a single "zero" slot and identical betting options. However, it stands out due to its unique rules that significantly impact the game's dynamics and player odds.
La Partage Rule
The La Partage rule, which translates to "the divide" in French, is a distinctive feature of French roulette that benefits players making even-money bets. This rule comes into effect when the ball lands on zero, and the player has placed an even-money bet such as red/black, odd/even, or high/low 1. Instead of losing the entire wager, the player receives half of their stake back 2.
The implementation of La Partage has a substantial impact on the house edge:
- In standard European roulette, the house edge on even-money bets is 2.70% 3.
- With La Partage in effect, the house edge is reduced to 1.35% 4.
This reduction in house edge makes French roulette particularly attractive to players who prefer even-money bets. The rule effectively mitigates the risk associated with the zero outcome, providing a form of insurance against total loss .
En Prison Rule
The En Prison rule, meaning "in prison" in French, is another unique feature of French roulette that applies to even-money bets when the ball lands on zero. Unlike La Partage, which immediately returns half the stake, En Prison gives players a second chance to recover their entire bet .
When En Prison is triggered:
- The player's bet is "imprisoned" or held for the next spin .
- If the subsequent spin results in a win for the player's chosen even-money bet, they receive their original stake back without additional winnings .
- If the next spin is a loss or results in another zero, the entire bet is forfeited 7.
The En Prison rule also reduces the house edge on even-money bets to 1.35%, matching the effect of La Partage 1. However, it introduces an element of suspense and extended play, as the fate of the bet is determined by an additional spin 2.
Similarities to European Wheel
Despite its unique rules, French roulette shares several key characteristics with European roulette:
- Wheel Layout: Both variants use a wheel with 37 pockets, including numbers 1-36 and a single zero 8.
- Betting Options: All standard inside and outside bets available in European roulette are also present in French roulette 9.
- Table Layout: The French roulette table layout is slightly different, but it still offers all the same betting options as European roulette 10.
The primary distinction lies in the application of La Partage or En Prison rules, which are not typically found in standard European roulette games .
It's worth noting that while both La Partage and En Prison rules offer similar advantages to players, their availability can vary:
- La Partage is more commonly found in both land-based and online casinos 1.
- En Prison is less frequently offered and may be less familiar to some players 11.
The choice between French roulette with La Partage or En Prison and standard European roulette often comes down to personal preference and risk tolerance. Players who favour even-money bets and appreciate the reduced house edge may find French roulette particularly appealing. However, those who enjoy a faster-paced game might prefer the straightforward approach of European roulette without these additional rules 2.
The Logic Behind Roulette Wheel Number Placement
The arrangement of numbers on a roulette wheel is far from random. It follows a carefully designed logic aimed at achieving specific objectives that enhance the game's fairness and unpredictability. This thoughtful placement serves multiple purposes, each contributing to the overall gaming experience.
Alternating Odd and Even
One of the primary considerations in roulette wheel design is the distribution of odd and even numbers. The numbers are arranged to alternate as much as possible, with no more than two consecutive odd or even numbers adjacent to each other 1. This alternation ensures a balanced distribution of odd and even numbers around the wheel, making it challenging for players to predict outcomes based on this characteristic alone.
On a European roulette wheel, there are 9 odd and 9 even numbers in each half of the wheel. However, most of these are arranged in pairs, with the rest alternating. This arrangement prevents any long sequences of odd or even numbers, maintaining the game's unpredictability 2.
High and Low Number Distribution
Another crucial aspect of roulette wheel design is the distribution of high (19-36) and low (1-18) numbers. The goal is to alternate between high and low numbers as much as possible around the wheel. This alternation creates a balanced distribution, making it difficult for players to target specific sections of the wheel based on number ranges.
In European roulette wheels, the high-low alternation is maintained consistently around the wheel, with one notable exception. Numbers 5 and 10, both low numbers, are positioned opposite the green 0. This break in the pattern occurs only once, with the high-low sequence maintained on either side of these numbers as the wheel continues back to 0 3.
Consecutive Number Placement
Perhaps the most intriguing aspect of roulette wheel design is the placement of consecutive numbers. The wheel is designed to make it extremely difficult for players to predict where the ball might land based on numerical sequences.
If one were to draw a line connecting the numbers in sequence from 0 to 36 on a European wheel, they would find themselves jumping from one side of the wheel to the other for 34 out of the 37 numbers. This seemingly haphazard arrangement of consecutive numbers is a key factor in generating suspense and preventing late betting players from guessing a range of possible numbers 4.
This design element serves multiple purposes:
-
It confuses novice players, making it challenging to create a mental picture of the wheel and understand the relationships between numbers and sectors 1.
-
It makes it difficult for players to notice any potential bias in the wheel or to bet on specific sectors 1.
-
It adds an element of excitement and unpredictability to each spin, as the ball's trajectory becomes less predictable 4.
The roulette wheel's number placement is a testament to the game's design ingenuity. By carefully balancing odd and even numbers, distributing high and low numbers, and strategically placing consecutive numbers, the wheel maintains fairness while maximising unpredictability. This intricate design ensures that roulette remains a game of chance, where each spin offers an equal opportunity for any number to come up, regardless of previous outcomes or player predictions.
Popular Roulette Numbers and Why
In the world of roulette, certain numbers have gained popularity among players for various reasons, ranging from cultural significance to strategic positioning on the wheel. While the odds of winning remain the same for all numbers, players often gravitate towards specific choices based on personal beliefs, superstitions, or perceived patterns.
The Allure of Number 17
One of the most popular numbers in roulette is 17. Its appeal lies not in any cultural or numerical significance, but rather in its strategic position on the roulette table. Located right in the middle of the layout, 17 naturally attracts players who are drawn to symmetry, especially in live roulette games featuring a physical table 1. This central placement makes it a favourite among seasoned players, who find it visually appealing and easy to locate.
Other Favoured Numbers
Several other numbers have gained popularity among roulette enthusiasts for various reasons:
-
Number 7: Widely considered lucky across many cultures, 7 is a common choice for both novice and experienced players. Its association with good fortune makes it an attractive option in a game based on chance 2.
-
Numbers 23 and 24: These numbers are often played as a split bet. The number 23 is associated with change and innovation in numerology, while 24 has an inexplicable attraction for many players 3.
-
Number 3: Despite being considered a "cold" number in roulette, 3 remains a popular choice. Some players believe it's "due" for a win, while others may be influenced by its significance in ancient Greek philosophy 4.
-
Number 25: Often played in conjunction with 17, as it's positioned directly to the right of 17 on the wheel. Some players bet on 25 as a backup in case the ball narrowly misses 17 .
-
Numbers 13 to 24: This group, known as the second dozen, is popular as it contains three of the most favoured numbers (17, 23, and 24) .
Myths and Superstitions
Roulette, like many games of chance, is surrounded by myths and superstitions that influence players' number choices:
-
Hot and Cold Numbers: Some players believe in betting on "hot" numbers that have won multiple times during a session. Conversely, others prefer "sleeping" or "cold" numbers that haven't appeared for a while, believing they're due for a win .
-
Lucky Numbers: Many players choose numbers based on personal significance, such as birthdays, anniversaries, or favourite years. However, these "lucky" numbers don't actually increase the chances of winning .
-
Avoiding Unlucky Numbers: In Western cultures, 13 is often considered unlucky, leading many players to avoid it. Similarly, some players steer clear of number 6, possibly due to its association with 666 in biblical contexts 7.
-
Wheel Position: Some players believe that certain wheel positions are more likely to win. For instance, the number 0 (or 00 in American roulette) is often avoided due to its position at the top of the wheel and its association with the house advantage 1.
It's crucial to understand that despite these popular beliefs and preferences, roulette remains a game of pure chance. Each spin of the wheel is an independent event, and the probability of any number coming up remains constant, regardless of past results or player superstitions 2. Modern roulette games, both in physical casinos and online platforms, are designed to deliver fair and random results, often audited by independent testing laboratories to ensure their integrity 8.
While playing popular numbers or following superstitions can add an element of personal engagement to the game, it's important for players to approach roulette with the understanding that no strategy or number choice can guarantee a win or influence the outcome of a spin.
Strategies for Betting on Roulette Wheel Numbers
Roulette offers a variety of betting options, each with its own risk-reward profile. Players can choose from inside bets, outside bets, or combination bets to create their personal strategy. Understanding these options and their implications is crucial for developing an effective approach to the game.
Inside Bets
Inside bets are placed on specific numbers or small groups of numbers on the inner section of the table. These bets offer higher payouts but have a lower probability of winning compared to outside bets 1. Some popular inside bets include:
- Straight Up: A bet on a single number, offering the highest payout but lowest odds of winning.
- Split Bet: A wager on two adjacent numbers on the table.
- Street Bet: A bet on three numbers in a horizontal line.
- Corner Bet: A wager on four numbers that form a square on the table.
- Six Line Bet: A bet on two adjacent horizontal lines, covering six numbers.
Outside Bets
Outside bets cover larger groups of numbers and offer a higher probability of winning, albeit with lower payouts 2. Common outside bets include:
- Red/Black: A bet on whether the winning number will be red or black.
- Odd/Even: A wager on whether the number will be odd or even.
- High/Low: A bet on whether the number will be in the range of 1-18 (low) or 19-36 (high).
- Dozens: A bet on one of three groups of 12 numbers (1-12, 13-24, or 25-36).
- Columns: A wager on one of the three vertical columns of numbers on the table.
Outside bets are particularly popular among new players and those who prefer a more conservative approach, as they offer nearly a 50% chance of winning for even-money bets like red/black, odd/even, and high/low 3.
Combination Bets
Combination bets involve placing multiple wagers on different outcomes simultaneously. While this approach may seem to increase the chances of winning, it's important to note that the expected average profit per round remains the same for all types of bets in roulette 4. The house edge, which is 2.7% for European roulette with a single zero, applies universally across all betting combinations .
When considering combination bets, players should be aware that:
- The number of combined bets doesn't affect the overall expected profit.
- The distribution of the total bet across individual wagers doesn't impact the long-term outcome.
- While some combinations may have a higher probability of winning, the amount won or lost always leads to the same expected profit on average .
It's crucial to understand that there is no optimal way to combine individual bets to maximise profit or winning probability in roulette. The game's design ensures that the house maintains its edge regardless of the betting strategy employed.
Conclusion
Understanding roulette wheel numbers has a significant impact on players' strategies and enjoyment of the game. From the intricacies of European, American, and French layouts to the logic behind number placement, this guide sheds light on the fascinating world of roulette. The careful design of the wheel, with its balanced distribution of odd, even, high, and low numbers, ensures fairness while keeping the game unpredictable and exciting.
To wrap up, while popular numbers and betting strategies can add to the thrill of roulette, it's crucial to remember that each spin is independent and purely chance-based. Whether you're drawn to inside bets, outside bets, or a mix of both, the key is to approach the game with a clear understanding of the odds and to play responsibly. In the end, roulette remains a game of chance, offering entertainment and the possibility of wins to those who understand its nuances.
