American vs European Roulette at Live Dealer Casinos: Which Should You Play?

The difference between American and European roulette looks small on the surface — one extra pocket on the wheel. In practice, that single pocket is one of the most consequential decisions you can make before sitting at a live dealer table.

The double zero (00) in American roulette doesn't just add a number. It nearly doubles the house edge compared to European roulette — from 2.7% to 5.26%. That difference compounds across every bet you place in a session. At £10 per spin, 40 spins per hour, the mathematical cost difference between the two variants is approximately £10 per hour in expected losses. Over a two-hour session, that's £20 — paid not in a single visible transaction, but absorbed quietly across dozens of spins.

That said, there are specific situations and player profiles where American roulette makes sense. This guide covers both fairly, explains the mathematics clearly, and gives you concrete strategic guidance for whichever variant you choose.

For broader context on the live dealer gaming environment and how roulette fits within it, our guide to how live dealer games became so popular covers the format's development and what distinguishes live roulette from its online RNG equivalent.

The Core Difference: What That Extra Zero Actually Means

Before anything else, let's be precise about what distinguishes these two variants — because the marketing language around both games obscures the mathematical reality.

American Roulette: The Mechanics

American Roulette features 38 pockets on the wheel: numbers 1–36, a single zero (0), and a double zero (00). The presence of both zero pockets is what defines the variant.

Key figures:

• 38 total pockets
• House edge: 5.26% on all standard bets
• Return to Player (RTP): approximately 94.74%
• Probability of winning a straight-up number bet: 1/38 = 2.63%

The house edge figure of 5.26% applies uniformly across virtually all bets in American roulette — outside bets (red/black, odd/even), inside bets (straight up, split, corner), and combination bets all carry the same edge. The one exception is the five-number bet (0, 00, 1, 2, 3), which carries a house edge of 7.89% — the worst bet on the table and one to avoid entirely.

European Roulette: The Mechanics

European Roulette features 37 pockets: numbers 1–36 and a single zero (0). No double zero.

Key figures:

• 37 total pockets
• House edge: 2.70% on standard bets
• RTP: approximately 97.30%
• Probability of winning a straight-up number bet: 1/37 = 2.70%

The single zero is what produces the house edge — in a truly fair game, a straight-up number bet would pay 36:1. European roulette pays 35:1, with the difference representing the house's mathematical advantage.

The En Prison Rule: An Additional European Advantage

Many European roulette implementations — and most live dealer versions — include the En Prison rule, which further reduces the effective house edge on even-money outside bets.

When the ball lands on zero and you have an even-money bet placed (red/black, odd/even, high/low), the En Prison rule allows your bet to be "imprisoned" for one additional spin rather than immediately collected by the house. If the next spin produces your outcome, your original stake is returned. This effectively halves the house edge on even-money bets to approximately 1.35% — making European roulette with En Prison one of the best mathematical propositions in live casino gambling.

Not all platforms implement En Prison, and the rule may be labelled differently across providers. Check before playing if this rule is relevant to your strategy.

The Numbers in Practice: What the House Edge Costs You

Abstract percentages are harder to internalise than concrete figures. Here's what the house edge difference means in real terms:

These are expected values — actual session outcomes will vary around these figures due to variance. But over extended play, actual results converge toward these mathematical expectations.

When American Roulette Makes Sense

Despite the less favourable mathematics, American roulette has legitimate contexts where choosing it is reasonable:

• Platform availability — Some live dealer platforms, particularly those serving North American markets, offer American roulette with better production quality, more engaging hosts, or superior streaming compared to their European roulette equivalents. If the live dealer experience quality is significantly better in American format on a specific platform, that qualitative difference may matter to you.
• Specific game variants — Some American roulette implementations include unique side bets, bonus features, or studio atmospheres not available in European format. Asia Gaming Live Roulette follows the single-zero European structure, but certain American roulette variants offer features that genuinely differentiate the experience.
• Explicit preference for higher variance — The extra pocket does add variance. Players who specifically enjoy higher-risk, more volatile sessions may find American roulette's dynamics preferable as an entertainment choice, with the mathematical cost consciously accepted as the price of that experience.

Strategies for American Roulette

Given the higher house edge, strategic discipline matters more in American roulette than European:

• Prioritise outside bets — Even-money outside bets (red/black, odd/even, high/low) carry the same 5.26% house edge as inside bets, but their near-50% win probability produces more consistent session results with lower variance. For American roulette players, outside bets are the rational primary strategy.
• Avoid the five-number bet — The 0, 00, 1, 2, 3 combination bet carries a 7.89% house edge — the worst bet on any standard roulette table. There is no strategic justification for placing it.
• Strict bankroll management — The higher house edge makes session losses accumulate faster than in European roulette. Set a hard session loss limit before playing and treat it as non-negotiable. The mathematical expectation at American roulette means extended sessions are more costly than equivalent European sessions by a significant margin.
• Column and dozen bets — These pay 2:1 and cover 12 of the 36 non-zero numbers. While still subject to the 5.26% edge, they offer a middle ground between outside bet consistency and inside bet variance that some players find preferable for managing session dynamics.

Why European Roulette Is the Default Recommendation

The mathematics are straightforward: European roulette gives you better odds on every single bet, in every situation, with no offsetting disadvantage. The single zero produces a 2.7% house edge versus 5.26% — a difference that compounds across every spin you make.

For players who want to maximise their expected session value, minimise their expected losses, and have the most favourable conditions for any roulette strategy they apply, European roulette is consistently the correct choice.

Live Dealer European Roulette Variants Worth Knowing

The European roulette format is the basis for several notable live dealer implementations that enhance the base game:

• Authentic Gaming Live Grand Roulette keeps the European roulette format but adds premium live dealer presentation — a popular choice for players who want the mathematical advantage of European rules with high production quality.
• Authentic Gaming Live Night Club Roulette uses the same classic European roulette base presented through a darker, nightclub-style live table atmosphere — the same odds in a distinctly different visual environment.
• Evolution Gaming's Live Auto Roulette La Partage implements the La Partage rule — similar to En Prison — where half your even-money stake is returned on a zero spin, reducing the effective house edge to 1.35% on those bets.
• Evolution's Live Instant Roulette operates on European rules with multiple wheels running simultaneously, eliminating wait time between spins — a format that suits players who want continuous action without the session pace constraint of a single-wheel broadcast.

Strategies for European Roulette

The lower house edge in European roulette creates more strategic flexibility than American roulette allows:

• Utilise En Prison or La Partage — When available, these rules on even-money bets reduce the house edge to 1.35% — among the best odds in live casino gambling. Building a strategy around even-money outside bets at a table offering these rules is the mathematically soundest approach to roulette.
• Spread bets more liberally — The lower house edge means the mathematical cost of covering multiple numbers is proportionally lower. Players who enjoy combination betting — covering sections of the wheel, using neighbour bets, or building call bets — will find European roulette more accommodating than American.
• Neighbour bets and sector play — European roulette implementations typically offer the full French roulette call bet menu: Voisins du Zéro, Tiers du Cylindre, Orphelins, and Jeu Zéro. These cover specific wheel sectors and can be used to build strategies around physical wheel sections rather than table layout sections. Our roulette systems guide covers these approaches in detail.
• Extended session sustainability — At 2.7% house edge versus 5.26%, European roulette allows proportionally longer sessions at the same effective mathematical cost. For players who value extended play time as part of the experience, this translates to meaningfully more spins per bankroll unit.

Head-to-Head Comparison

Choosing the Right Variant for Your Situation

For Beginners

Start with European roulette. The lower house edge is more forgiving during the learning period, the En Prison rule provides a partial safety net on even-money bets, and the strategic flexibility allows you to experiment with different bet types without the additional mathematical penalty that American roulette imposes.

Our specific recommendation for new live dealer roulette players: begin with even-money outside bets at a European table with En Prison available. This gives you the best possible mathematical starting point while you develop familiarity with the pace and interface of live dealer roulette.

For Experienced Players

European roulette remains the better mathematical proposition regardless of experience level. The question for experienced players is which European roulette variant suits their preferred play style — high-production European tables, specific call bet availability, immersive live game shows like live game shows like Lightning Roulette (which modifies the base game with multipliers), or standard European format with maximum flexibility.

For High-Stakes Players

The mathematical cost difference between variants is amplified at higher stakes. At £50 per spin, 50 spins per hour: European roulette expected loss is £67.50/hour; American roulette expected loss is £131.50/hour. That £64/hour difference is not trivial. High-stakes players have the clearest financial incentive to choose European format and to seek out tables offering En Prison or La Partage rules specifically.

Live Dealer Roulette: What to Look For Beyond the Variant

Once you've chosen your variant, several platform-specific factors affect the live dealer roulette experience:

• Streaming quality — Live dealer roulette depends on clear, reliable video to observe the wheel spin and ball landing. Test your platform's streaming stability before committing to extended sessions.
• Camera angles — Quality live roulette implementations offer multiple camera angles, including close-up wheel views that confirm where the ball lands. Single-angle streaming is a downside worth noting.
• Bet timing indicators — Clear countdown timers for the betting window are a usability feature that matters more than it sounds in live play. Platforms with unclear or short betting windows create avoidable pressure.
• En Prison implementation — If even-money outside bets are central to your strategy, verify that the specific table you're playing implements En Prison or La Partage before your session, not during it.
• Betting limits — Minimum and maximum bet limits vary significantly between live dealer tables. Check that the table's limits accommodate your intended stake range before joining.

Responsible Gambling at Live Dealer Roulette

Roulette's fast pace — particularly in variants like Live Instant Roulette — and the continuous availability of live dealer tables create specific responsible gambling considerations.

Set a session loss limit before opening the table, not after your first losing run. Treat it as non-negotiable. The mathematical expectation of roulette means no strategy system — Martingale, Fibonacci, D'Alembert, or any other — changes the house edge or produces positive expected value over time. Systems that claim otherwise are mathematically incorrect. Read our guide to roulette systems for an honest assessment of what these approaches actually deliver.

Every regulated live casino platform offers deposit limits, loss limits, session time limits, and self-exclusion tools. Use them proactively, particularly in a format as continuous and fast-paced as live dealer roulette. For context on responsible gambling across live casino game sessions, these tools exist precisely because the format's accessibility and continuity create conditions where session overrun is a genuine risk.

Conclusion: The Choice Is Clear for Most Players

The choice between American and European roulette has a mathematically correct answer for most players in most situations: European roulette, ideally at a table with En Prison or La Partage available for even-money bets.

The 2.55 percentage point difference in house edge sounds modest. The actual cost difference across a typical session is not. Every hour of play, every spin, the extra zero in American roulette is working against you at nearly twice the rate of European roulette. That's a concrete, measurable cost that no entertainment feature of American roulette offsets for a player whose primary goal is maximising their time and money at the table.

Choose American roulette consciously if you have specific reasons — variant preference, platform quality, deliberate higher-variance play. Avoid it by default. And whichever variant you choose, combine it with the responsible gambling tools your platform provides and the realistic mathematical expectations this guide has outlined.
