Roulette Outside Bets Guide: Odds, Payouts & Bet Types Explained
Feeling overwhelmed by the options on a roulette table? Many players are drawn to roulette because its basic choices are easy to grasp, yet the variety of bets can still be confusing. Outside bets simplify the game by covering larger groups of numbers and offering steadier, more frequent outcomes.
This guide explains what outside bets are, how each type works, the odds and payouts you can expect in European roulette, and practical tips for playing sensibly. Read on to get a clear picture of the main outside bets and how they fit into the wider game.
What Are Roulette Outside Bets?
Outside bets are wagers placed in the areas around the numbers grid on the roulette table rather than on individual numbers. They cover broader categories—such as colour, parity (odd/even), ranges (high/low), or blocks of twelve numbers—so a single stake applies to many possible outcomes. Because they include more numbers, these bets win more often than inside bets but pay out less when they do.
On a standard European table (single zero), outside bets lose if the ball lands on zero, which introduces the house edge. That edge is the same across most outside bets on a single-zero wheel, so your choice among them should reflect how much volatility you prefer rather than an expectation of long-term advantage. Next, we’ll look at each bet type in turn and what to expect from them.
Types of Roulette Outside Bets
Outside bets group numbers by simple features that are easy to spot on the table layout. Understanding the distinctions will help you choose the style of play you want—whether that is frequent smaller wins or slightly higher payouts with less frequent wins.
Red or Black Bets
A red or black wager covers every number of the chosen colour except zero. Because each colour contains 18 numbers on a single-zero wheel, these bets give a near-50% chance of success on any spin, subject to the presence of the zero. The zero is not included in either colour and is what creates the house edge, so wins are not guaranteed.
These bets pay even money when they succeed. Players often choose them for straightforward staking and easy-to-follow strategies, since outcomes and payouts are simple to understand.
Odd or Even Bets
Odd or even bets select all odd numbers or all even numbers, again excluding zero. These bets function much like the colour wagers in terms of coverage and frequency of winning outcomes, offering a similar near-50% chance on a single-zero wheel.
They also pay even money, and are commonly used by players who prefer to base decisions on simple numerical properties rather than colours or specific sections of the layout.
High or Low Bets
High/low bets split the numbers into two ranges, typically 1–18 and 19–36. Each range contains 18 numbers and behaves similarly to the colour and odd/even bets, with the same caveat about zero reducing the outright probability of winning on any single spin.
High/low bets pay even money and are popular with players who like the clear division of the wheel into two halves and the relatively frequent chance of success compared with inside-number wagers.
Dozens Bets
Dozens divide the wheel into three groups of twelve consecutive numbers: 1–12, 13–24 and 25–36. Each dozens bet covers exactly one-third of the wheel’s non-zero numbers, offering a balance between frequency and payout that sits between the one-to-one outside bets and the higher-paying inside-number wagers.
These bets typically pay 2 to 1, making them a middle ground for players seeking larger payouts than even-money bets while still maintaining a reasonable chance to win on each spin.
Column Bets
Column bets cover one of the three vertical columns on the table layout. Although each column also contains twelve numbers, its distribution across the wheel differs from the consecutive blocks of the dozens. The column areas are clearly marked at the bottom of the layout and give the same coverage and payout as a dozens bet.
Column bets also pay 2 to 1 and are useful when players prefer the layout-based grouping rather than consecutive numerical groupings, while offering the same overall probability as a dozens bet.
Odds & Payouts for Each Outside Bet
On European (single-zero) roulette, the maths behind outside bets is straightforward once you know how many numbers each bet covers.
- Red/black, odd/even and high/low: pay 1:1. These bets cover 18 of 37 possible outcomes each, so the win probability is 18/37 and the house edge is 2.7%.
- Dozens and columns: pay 2:1. Each covers 12 of 37 outcomes, so the probability of winning is 12/37 and the house edge is likewise 2.7%.
Because American wheels or specialised rules (such as French table options) change the number of zero pockets or offer partial returns, odds and the effective house edge differ on those wheels. European tables with a single zero keep the calculations above consistent, making it simpler to compare bet types and their likely short-term behaviour.
How Do Outside Bets Differ from Inside Bets?
The key difference lies in scope and volatility. Inside bets are placed on individual numbers or small clusters and therefore have lower probabilities but higher payouts. Outside bets sacrifice payout size for more frequent wins because each stake covers many more numbers.
Outside bets typically include options such as red or black, odd or even, and columns or dozens. These cover larger sections of the wheel, so each spin gives a better chance of a return, albeit a smaller one. Inside bets focus on single numbers or tight groups, so wins are less common but pay out at much higher multiples when they occur.
This contrast shapes how sessions feel at the table. Inside betting brings larger but rarer returns, which produces higher variance and can lead to sharp swings in a player’s bankroll. Outside betting produces steadier, smaller wins and tends to smooth out short-term fluctuations, though the house edge remains the same across most bets.
Which approach suits a given player depends on appetite for swings and the type of experience they want. Some players prefer the excitement of chasing bigger hits even if losses between wins are more likely, while others favour a calmer, more measured pace with fewer dramatic ups and downs. Neither approach changes the underlying mathematical expectation, so outcomes over time are governed by chance and the built-in house advantage.
With that distinction clear, the next section considers what this means for outcomes over time. It will look at how choice of bet affects variance, bankroll management and the likely pattern of wins and losses, while emphasising the importance of responsible play.
Can You Improve Your Roulette Winnings With Outside Bets?
Outside bets offer greater chances of winning on individual spins, but they do not change the underlying house edge of the game. The single zero on the European wheel guarantees the house advantage remains; no betting pattern or sequence can alter that edge in the long run.
For players who prefer more regular, smaller wins, outside bets are a sensible choice. However, they should be viewed as a style preference rather than a method for increasing long-term profitability. Keeping realistic expectations and managing stakes are the practical ways to control your experience at the table. Ahead, we address some common misunderstandings that often influence player choices.
Common Myths About Outside Bets
Several persistent misconceptions shape how players approach outside bets.
- Myth: Outside bets boost long-term profit. In reality, the house edge applies equally across these wagers on a single-zero wheel, so long-term expectation remains negative for the player.
- Myth: Staking systems recover losses. Increasing or changing stakes after losses does not change probabilities and cannot overcome the house advantage.
- Myth: Covering most bet types eliminates risk. Even combinations of outside bets leave the zero as a losing outcome, so no combination removes the house edge.
Separating these myths from fact helps set realistic goals and prevents chasing unlikely outcomes. With clearer expectations, players can choose bets that match their comfort with variance and session length.
Roulette Outside Bets: FAQs
Are outside bets safer than inside bets?
Outside bets generally win more often because they cover more numbers, which tends to reduce the size and frequency of losing streaks. That makes their results less volatile compared with many inside bets.
However, safer in this sense does not mean the house edge is reduced. The expected return over time remains governed by the game’s odds, so outside bets lower variance but do not change the underlying probability. All bets carry risk, and the possibility of loss always exists.
Can I use a strategy to improve my results with outside bets?
No betting system can change the underlying odds or guarantee profit. Patterns or progressions might influence how you pace your play, but they do not alter the mathematical expectation of the game.
Practical approaches such as managing your bankroll, setting win and loss limits, and keeping sessions short can help you control how much you risk and support responsible play. These measures influence behaviour and potential losses rather than the probability of winning.
What happens if the ball lands on zero and I’ve placed an outside bet?
Outside bets lose when the zero comes up on standard tables. That outcome removes the winning cover offered by even-money and other outside options on most single-zero wheels.
Some French roulette variants include rules such as la partage or en prison that may return part of a stake or hold it for a single spin when zero appears. Those rules vary by game and venue, so check the table rules before you play.
Is there a maximum or minimum stake for outside bets?
Bet limits are set by the operator or venue and can vary from table to table. Limits may apply to individual bets or to the total amount you can place in a round.
Always check the posted table rules or the operator’s terms so you know the minimum and maximum stakes, and choose amounts you can afford to lose.
Where can I get help if gambling stops being fun?
If gambling becomes a problem, support is available through a range of self-help tools and specialist organisations. Many operators offer options such as deposit limits, reality checks, time-outs and self-exclusion.
Independent services and helplines can provide confidential advice and practical support. If you are concerned about your gambling, seek help promptly to protect your wellbeing.
Tips for Playing Roulette Outside Bets Responsibly
A thoughtful approach improves the experience when placing outside bets and helps avoid unintended losses. Clear boundaries and measured habits make play more sustainable.
Set clear spending limits before you start and stick to them; practical tools like deposit caps are useful for maintaining control. Allow time away from the table to reflect on play and avoid emotional decisions that may lead to chasing. Treat roulette as a paid form of entertainment rather than a route to financial gain, and monitor behaviour for signs it is having an adverse effect. If play becomes difficult to manage, use available support and operator safeguards to take a step back.
Playing with awareness and limits makes the game more enjoyable and keeps outcomes in perspective.
