European Roulette is the most popular variant of roulette worldwide, featuring a wheel with 37 pockets numbered 0 to 36. Distinguished by its single zero, it offers players significantly better odds than American Roulette with a house edge of just 2.7%.
European Roulette stands as the gold standard of casino roulette games, offering players the most favorable odds and a rich gaming experience that has captivated gamblers for centuries. Originating in France during the 18th century, this elegant game of chance combines simplicity with strategic depth, making it accessible to beginners while providing enough complexity to engage experienced players. The defining characteristic of European Roulette is its single-zero wheel configuration, which fundamentally improves player odds compared to its American counterpart.
Understanding the mechanics, betting options, and mathematical principles behind European Roulette is essential for anyone looking to play intelligently. This comprehensive guide explores every aspect of the game, from basic rules to advanced betting strategies, providing you with the knowledge needed to approach the table with confidence.
The European Roulette wheel contains 37 pockets numbered from 0 to 36. The numbers are arranged in a specific non-sequential order: 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. This arrangement is carefully designed to distribute odd and even numbers, as well as high and low numbers, as evenly as possible around the wheel.
The color scheme follows a precise pattern: 18 numbers are red (1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36) and 18 are black (2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35). The single zero pocket is colored green, distinguishing it from all other numbers and representing the house advantage.
The betting table mirrors the wheel numbers but arranges them in a logical grid format for easier betting. Numbers 1 through 36 are displayed in three columns of twelve rows each, with the zero positioned at the top. The table is divided into two main betting areas: inside bets (individual numbers and small groups) and outside bets (larger groups, colors, and characteristics).
Outside betting sections include areas for red/black, odd/even, high/low (1-18 and 19-36), dozens (1-12, 13-24, 25-36), and columns. This layout allows players to quickly place multiple types of bets before each spin, accommodating various playing styles and risk tolerances.
The mathematical advantage in European Roulette is straightforward and transparent. With 37 total pockets and payouts based on a 36-number system, the house edge is calculated as 1/37, which equals approximately 2.7%. This means that over the long term, the casino expects to retain 2.7% of all money wagered on the table.
This house edge applies uniformly to nearly all bets on the European Roulette table, whether you bet on a single number, red/black, or any other standard option. The consistency of this edge is one reason European Roulette is preferred by knowledgeable players—there are no trap bets with significantly worse odds, unlike in American Roulette where the five-number bet carries a 7.89% house edge.
The critical difference between European and American Roulette is the presence of a double zero (00) on the American wheel, creating 38 pockets instead of 37. While payouts remain the same in both versions, the additional pocket increases the house edge to 5.26% in American Roulette—nearly double that of European Roulette.
For practical purposes, this means that playing European Roulette instead of American Roulette effectively doubles your expected playing time with the same bankroll, or alternatively, cuts your expected losses in half. This mathematical reality makes European Roulette the superior choice whenever both options are available.
European Roulette offers a comprehensive range of betting options, each with specific odds and payout ratios. Understanding these options is fundamental to developing an effective playing strategy.
Inside bets are placed on the numbered grid portion of the table and generally offer higher payouts with lower probability of winning.
Outside bets cover larger groups of numbers and offer higher winning probability but lower payouts.
The game begins when players place their chips on the betting table, selecting from numbers, colors, or various combinations. The croupier spins the wheel in one direction and launches the ball in the opposite direction. Once the ball begins to slow, the croupier announces no more bets are accepted.
After the ball settles into a pocket, the croupier places a marker on the winning number, collects all losing bets, and distributes payouts to winners according to the established payout ratios. The process then repeats for the next round, allowing players to adjust their betting strategy based on their experience.
European Roulette sometimes includes special French bets, also called announced bets or call bets, which cover specific sections of the wheel rather than the table layout. These bets require multiple chips and follow the physical arrangement of numbers on the wheel.
This bet covers the 17 numbers closest to zero on the wheel, from 22 to 25 (inclusive). It requires 9 chips placed in specific combinations: one chip on 0-2-3, one on 4-7, one on 12-15, one on 18-21, one on 19-22, two on 25-26-28-29, and two on 32-35. This bet covers nearly half the wheel and is popular among players who believe in wheel bias or hot zones.
Covering the third of the wheel opposite zero, this bet includes 12 numbers from 27 to 33 (on the wheel). It requires 6 chips placed as splits: 5-8, 10-11, 13-16, 23-24, 27-30, and 33-36. This bet is simpler than Voisins and covers a coherent wheel section.
The orphans bet covers the 8 numbers not included in Voisins or Tiers, split into two wheel sections. It requires 5 chips: one straight on 1, and splits on 6-9, 14-17, 17-20, and 31-34. This bet covers the remaining wheel segments and is less commonly played.
A neighbours bet covers a chosen number plus the two numbers on each side of it on the wheel, requiring 5 chips total. For example, betting on 17 and its neighbours would cover 25, 2, 21, 17, and 34. This bet allows players to cover a small wheel section centered on their preferred number.
While no betting system can overcome the house edge in the long run, various strategies help players manage their bankroll and structure their gameplay. Understanding these systems allows you to choose an approach that matches your risk tolerance and playing style.
The Martingale is the most famous roulette system. Players double their bet after each loss, returning to the base bet after a win. The theory is that one win recovers all previous losses plus one unit of profit. However, this system requires a large bankroll and faces table limits that can prevent continued doubling. It works best for short sessions but carries significant risk of catastrophic losses during extended losing streaks.
A more conservative approach, the D'Alembert system increases bets by one unit after a loss and decreases by one unit after a win. This creates a gentler progression than Martingale and requires less bankroll. The system is based on the theory of equilibrium, assuming wins and losses will eventually balance out, though this assumption has no mathematical validity in independent random events.
Based on the famous Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, etc.), this system moves one step forward in the sequence after a loss and two steps back after a win. It offers a middle ground between aggressive and conservative progression systems, with slower bet escalation than Martingale but more aggressive recovery than D'Alembert.
The simplest and mathematically soundest approach is flat betting—wagering the same amount on each spin regardless of outcomes. While this lacks the excitement of progressive systems, it provides maximum playing time for your bankroll and eliminates the risk of rapid losses during bad streaks. Combined with disciplined bankroll management, flat betting is often the most sustainable long-term approach.
Understanding the mathematical reality of European Roulette helps set realistic expectations. Every bet on the table (except for special rules like La Partage or En Prison) has the same expected value: a loss of 2.7% of the amount wagered. This means that if you bet 100 units over time, you can expect to lose approximately 2.7 units on average.
Short-term variance means actual results will deviate significantly from this expectation in any given session. You might win substantially or lose more than expected. However, the more spins you play, the closer your results will trend toward the mathematical expectation. This principle, known as the law of large numbers, is fundamental to casino game mathematics.
Online casinos have made European Roulette more accessible than ever, offering both virtual and live dealer versions. Virtual roulette uses random number generators to determine outcomes, providing fast-paced gameplay with no waiting between spins. Live dealer roulette streams real wheels operated by professional croupiers, replicating the authentic casino experience from home.
Online play offers several advantages: lower minimum bets, the ability to play at your own pace, detailed statistics tracking, and often better odds than land-based casinos. Many online platforms also offer free play modes, allowing you to practice and understand the game without risking money. When choosing an online casino, verify licensing, read reviews, and confirm that European Roulette (not American) is offered.
European Roulette should be approached as entertainment with an associated cost, not as a money-making opportunity. Set strict loss limits before playing and never chase losses by exceeding your predetermined budget. Understand that the house edge ensures the casino profits over time, and no strategy can change this fundamental mathematical reality.
Take regular breaks during play to maintain clear judgment, and never gamble with money needed for essential expenses. If you find yourself unable to control your gambling behavior or experiencing negative consequences, seek help from responsible gaming organizations. Most jurisdictions offer free counseling and support services for problem gambling.
European Roulette represents the optimal version of this classic casino game, offering players the best possible odds in a roulette format. Its single-zero wheel configuration, transparent rules, and wide variety of betting options create an engaging experience that balances simplicity with strategic depth. While the house edge ensures the casino maintains a mathematical advantage, understanding the game's mechanics, probability, and betting systems allows you to play intelligently and maximize your entertainment value.
Whether playing in a traditional casino or online, European Roulette provides an elegant gaming experience rooted in centuries of gambling tradition. By approaching the game with realistic expectations, solid bankroll management, and knowledge of the mathematical principles at work, you can enjoy this timeless game responsibly while giving yourself the best possible chance of a positive session outcome.
European Roulette has 37 pockets with a single zero, giving a house edge of 2.7%, while American Roulette has 38 pockets with both zero and double zero, resulting in a 5.26% house edge. This makes European Roulette significantly more favorable for players.
No betting system can overcome the house edge in the long term. Systems like Martingale or Fibonacci can structure your play and manage short-term variance, but they cannot change the mathematical expectation of losing 2.7% of total wagers over time.
All standard bets in European Roulette have the same 2.7% house edge, so no bet is mathematically superior. Choose bets based on your preferred balance between payout size and winning frequency. Outside bets offer frequent small wins, while inside bets provide larger but less frequent payouts.
The probability of any specific number appearing on a single spin is 1 in 37, or approximately 2.7%. This probability remains constant for every spin, as each spin is an independent event unaffected by previous results.
Both options have advantages. Online play typically offers lower minimum bets, faster gameplay, and convenience, while physical casinos provide social atmosphere and tangible experience. Choose based on your personal preferences, but always ensure you are playing European Roulette rather than American for better odds.
French bets are special wagers covering specific wheel sections, such as Voisins du Zéro or Tiers du Cylindre. They offer no mathematical advantage but allow you to bet on wheel sections rather than table layout patterns. Use them if you prefer wheel-based betting strategies or find them more intuitive.
