European Roulette
Last updated: 2025-12-26
European roulette is a classic table game where the outcome is determined by where the ball lands on the roulette wheel. The European version is identified by its single zero (0), which affects the game’s probabilities and house edge. This guide covers the game’s background, basic rules, common bet types, and key differences from American roulette. The topic relates to the site’s broader casino games section.
Background of European Roulette
Roulette was developed in Europe in the 1700s and later became a staple casino game. The commonly known European roulette format today contains numbers 0–36. The single zero structure distinguishes it from the American version, which also includes 00.
Key Milestones
Early forms of roulette became popular in Europe.
The wheel with a single zero (0) is often associated with French development stages.
Roulette became established as part of casino game offerings.
How to Play European Roulette
In European roulette, the player selects a bet type from the table and places the bet before the round begins. During the round, the ball spins in the roulette wheel and lands on one number (0–36). Winnings are determined by whether the result matches the selected bet and what multiplier that bet type has.
Basic Game Structure
- Number Range 0–36
- Colors red and black (0 is green)
- Betting Areas outside bets and inside bets
Common Bet Types
Bets are often divided into two practical groups.
Probabilities and House Edge in European Roulette
European roulette has 37 possible outcomes (0–36). The house edge arises from the zero, as it does not belong to red or black, nor to even or odd numbers. When an outside bet (for example, red) has 18 winning numbers, the hit probability is 18/37 (approximately 48.65%), not 50%.
The generally stated house edge in European roulette is 2.70% (assuming standard payout tables). The hit probability for a single number is 1/37 (approximately 2.70%), and the typical payout is 35:1, which produces the same expected value as other basic bets.

European and American Roulette
The main structural difference is the number of zeros. European roulette has one zero (0), American roulette has two (0 and 00). This changes probabilities and house edge.
There is a separate overview of the American version’s structure on the American roulette page. Additionally, the roulette family includes a variant with fewer numbers called Mini Roulette, where probabilities and payouts differ from the standard game.
Roulette as a Digital Game and Demo Versions
Roulette is available in various implementations, such as random number generator-based digital versions and live implementations. Some services also offer a demo mode for the game, where bets are not real money bets. Demo mode is typically used to learn the interface and bet types.
When examining digital implementations from a consumer perspective, essential information includes the game’s rules, payout table, possible bet limits, and how randomness is implemented and audited. General principles related to payments and security are covered in the article on secure payment methods at online casinos.
Live Roulette and Game Transparency
Live roulette is a format where the dealer spins a physical roulette wheel in a studio and the round is transmitted via video stream. From the player’s perspective, key differences include camera angles, round tempo, bet placement duration, and how the result is transferred to the system (for example, optical recognition and game system confirmation).
- Real-time broadcast and visible wheel
- Standardized rules, but implementation details may vary
- Connection and latency can affect user experience, not the probabilities themselves
General information about live implementations can be found on the live casino dealers page. Background information on game developers’ development plans and release schedules is also available in the news article Evolution plans faster game releases next year.
Responsibility and Game Management
Roulette is a game of chance where individual round results cannot be predicted. At a practical level, topics related to game management include budgeting, limiting playing time, and identifying one’s own risk preferences. General background information for beginners is compiled on the online casino tips for beginners page.
Roulette is just one game type in a broader selection. If the goal is to understand differences between game categories, the site’s casino games section serves as a starting point.
Frequently Asked Questions
What is the house edge of European roulette
European roulette has 37 pockets (0–36), and the generally stated house edge is 2.70% with standard payout tables.
Why does one zero affect red/black bets
Red and black each cover 18 numbers, but there is also 0, which is neither red nor black. Therefore, the hit probability is 18/37, not 18/36.
What is the difference between digital roulette and live roulette
In digital roulette, the result is generated by a random number generator according to the game’s rules. In live roulette, the dealer spins a physical wheel in a video broadcast, and the result is transferred to the system in a way that depends on the implementation.
How does mini roulette differ from European roulette
Mini roulette has a smaller number of numbers than the traditional 0–36 structure. This changes probabilities and payout tables compared to European roulette.
