The Unique Aspects of European Roulette and How This Influences Strategy
European roulette’s main advantage is its single-zero wheel, featuring just 37 pockets instead of the 38 found on American wheels. This difference significantly reduces the house edge, dropping it from approximately 5.26% on American roulette to just 2.70% in European roulette. Over time, the smaller house edge can noticeably make a difference.
Consider even-money bets like red or black. In European roulette, these wagers have a win probability of about 48.65%, compared to 47.37% on American tables. Although this difference might seem minor, it becomes more noticeable over a longer period. Strategically, European roulette is the clear choice for anyone looking to optimize their odds.
European roulette also offers beneficial features, such as call bets, En Prison, and La Partage. These rules and wagering options provide more ways to manage bets strategically and potentially reduce losses when the ball lands on zero.
Focus on Call Bets
Call bets, also known as announced bets, are a distinctive feature of European roulette.
These wagers let you cover entire sections of the wheel in one bet instead of placing multiple individual chips across the table. You can either verbally announce your bet to the dealer or place it on the racetrack layout found on many European roulette tables.
European roulette’s wheel layout makes call bets particularly effective.
With only a single zero among the 37 pockets, numbers are evenly and logically arranged, unlike American wheels, where the double zero disrupts the sequence. This balanced layout enables strategic section bets, such as Voisins du Zéro, Jeu Zéro, Tiers du Cylindre, and Orphelins.
Each of these bets corresponds to specific segments of the wheel:
- Voisins du Zéro covers 17 numbers surrounding the zero and requires 9 chips placed across splits, corners, and trios. It offers roughly a 45.9% chance of hitting at least one number
- Jeu Zéro is essentially a smaller version of the Voisins du Zéro call bet. It covers the numbers in between (and including) 12 and 15 on the roulette wheel and uses 4 chips
- Tiers du Cylindre spans 12 numbers on the opposite side of the wheel from zero, placed using 6 split bets. The probability here is around 32.4%
- Orphelins picks up the remaining 8 numbers not covered by the other two, using 5 chips to place straight-up and split bets. This bet has about a 21.6% chance of winning
While the house edge for call bets remains 2.70%, their structure allows for broader coverage within a spin. This means there’s a greater chance that at least one number in the selected section will hit, even if the result depends on which specific number comes up.
Making Use of the En Prison Rule
One advantage occasionally found in European roulette, particularly on French-style tables, is the En Prison rule. It applies exclusively to even-money bets, including red/black, odd/even, or high/low. When in effect, it softens the impact of a zero outcome. Here’s how it works:
- If an even-money bet lands on zero, the stake is held on the table for one more spin rather than being lost immediately
- A marker is placed to indicate that the bet is “in prison”
- If the selection wins on the next spin, the original wager is returned without profit
- If it loses, the stake is forfeited
Some variations of this rule allow a second imprisonment if zero appears again, but most tables treat a second zero as a loss or resolve it with the La Partage rule instead.
La Partage, while similar in spirit, immediately returns half your stake when zero hits and takes the other half, with no second spin involved. Both rules reduce the house edge on even-money bets from 2.70% to approximately 1.35%.
This rule is most effective when used as part of a structured approach to even-money bets, where consistent patterns in bet sizing and decision-making are applied. By limiting the impact of zero outcomes, En Prison adds a small but meaningful buffer. Games that feature either En Prison or La Partage offer a clear advantage over standard tables; however, it’s worth checking their availability, as not all European roulette tables include these options.
Combine the Lower House Edge of European Roulette with Strategies
European roulette’s lower house edge can make structured betting systems, such as Martingale or D’Alembert, a bit less punishing over time. Below is a breakdown of how each method operates and where its limitations tend to appear.
The Martingale System
The Martingale is a negative progression system built around even-money bets.
After each loss, you double your wager, aiming to recover all previous losses with a single win. A player starting with $5 on red would double their bet after every loss: $10, $20, $40, $80, and so on, until red hits. When it does, they recover the entire losing streak plus a $5 profit, then reset.
In practice, the Martingale system runs into clear limitations. Table limits and personal bankrolls restrict how far the progression can go.
On top of that, it only takes a few losses in a row for the next bet to become unreasonably large. Even with European roulette’s lower house edge, a prolonged losing streak can quickly unravel the entire approach, leading to a steep and unrecoverable loss.
The D’Alembert System
The D’Alembert system takes a slower approach.
Instead of doubling, you increase your bet by one unit after a loss and decrease it by one unit after a win.
If you start at $5 and lose, you go to $10. If you win that round, the next bet drops back to $5.
This method is based on the assumption that wins and losses will balance out over time.
While the logic of adjusting bet size based on previous outcomes doesn’t change the odds, this method increases stakes more gradually and avoids the sharp jumps associated with Martingale.
Although slightly less aggressive than Martingale, the D’Alembert system does not eliminate the house edge or guarantee positive returns. Each spin remains independent, meaning past results have no influence on future outcomes.
What the system does offer is structure, which can support risk management and reduce impulsive decisions. Even so, the gradual progression still requires discipline, particularly when losses begin to accumulate.
Debunking Myths Around European Roulette Strategy
Even with more favourable odds, European roulette remains a game of chance. No strategy, system, betting progression, or wheel-reading method can alter that fact.
Still, plenty of myths persist, often leading to false confidence or unrealistic expectations. It’s important to separate fact from fiction before putting any betting approach into play.
In the next sections, we’ll address two of the most common misconceptions: the idea that roulette can be “solved” with the right strategy, and the belief that wheel bias can be spotted and exploited in modern casino environments.
There Are No Guarantees
One of the most persistent myths about roulette is the notion that a strategy can guarantee a profit.
Systems like Martingale are often pitched as foolproof methods, based on the assumption that a win is inevitable if you just keep betting. The problem is, roulette doesn’t work that way.
As established, every spin is independent. The probabilities don’t change, and no pattern or progression can influence the outcome. European roulette may offer a lower house edge, but it still tilts the odds slightly in favour of the house.
No system can alter that math. Whether you're placing flat bets or using structured approaches, the outcome over time will reflect the house edge.
What betting systems can offer is structure, which is the primary reason they exist. They help manage how you play, but, as mentioned, they don’t make the odds any better than they are. In European roulette, that’s as good as it gets: slightly more favourable conditions, but never a sure thing.
Wheel Bias is a Myth
Some players still chase the idea that they can find an edge by spotting patterns or flaws in the roulette wheel itself.
This concept, known as wheel bias, suggests that certain numbers may come up more often due to mechanical imperfections. While there have been rare historical cases of biased wheels being exploited, that scenario no longer applies in the modern day.
Modern roulette wheels are built with extreme precision. They’re also regularly inspected and maintained to ensure fairness. Any wear or imbalance that could affect outcomes is either corrected or leads to the wheel being replaced. Casinos also rotate wheels and track results internally to detect any statistical anomalies long before players can.
Attempting to identify a slight bias would require tracking thousands of spins just to detect a pattern that, if it exists at all, is likely negligible. Online, the concept becomes even less relevant; random number generators (RNGs) and rigorously maintained live dealer equipment eliminate the possibility entirely.
Believing that “hot” or “cold” numbers are linked to a wheel’s behaviour is a distraction. As we now know, every spin in European roulette is independent, and the wheel has no memory.
Strategies based on past outcomes or imagined imperfections don’t improve your chances; they just waste your focus. Stick to what you can control: your bets, your pacing, your bankroll, and your time at the table.
Bankroll Management for European Roulette
No roulette strategy works without discipline, and that starts with managing your bankroll.
One of the biggest mistakes players make is chasing losses, assuming a win is overdue.
In a game where every spin is random, that mindset can quickly unravel your entire balance.
- Set a strict budget. Decide how much you’re comfortable losing before you play, and treat that amount as spent. For example, if you bring $200 to the table, set that as your session limit. If it’s gone, the session ends, with reloading out of the question
- Break your bankroll into smaller parts. Divide your total into sessions or units, then size your bets so you can make at least 20-30 wagers per session. On a $200 bankroll, this could mean betting $5 to $10 per spin, giving you enough runway to weather short-term variance without depleting your funds too quickly
- Use stop-loss and stop-win limits. Decide ahead of time to walk away if you lose 25% of your bankroll, or if you hit a 50% profit. These limits protect you from the common trap of either spiralling into a bad run or giving back winnings through overconfidence
- Set time limits. Even if you're ahead, setting an exit point and leaving the table after a set period helps prevent decision fatigue and keeps your session intentional. Staying too long often leads to riskier bets or slipping into a losing streak
- Keep bet sizes consistent. Avoid the temptation to recover losses by doubling or going all-in. Roulette doesn’t reward emotional decisions. Controlled, steady play stretches your bankroll and helps you avoid rapid losses during cold streaks
