Roulette Outside Bets Explained: Payouts, Odds & Winning Chances
Fancy a spin on the roulette wheel but not sure where to start? Outside bets are one of the simplest ways to play—they cover larger groups of numbers and give you steadier chances on each spin.
Whether you’re new to online casinos or want clearer odds and payouts, this guide explains what outside bets are, how much they pay and what the real probabilities look like every round. Read on to place your chips with confidence.
What Are Roulette Outside Bets?
Roulette outside bets are wagers placed on the outer section of the betting table, surrounding the numbers. Instead of backing a single number, you bet on broader categories—such as red or black, odd or even, high or low, columns or dozens.
Because these bets cover more numbers, each one has a higher probability of winning than an inside bet, but the payout is lower per unit staked. On the layout, the outside bet options are shown in clearly labelled boxes, so you simply put your chips in those areas when you want an outside bet.
Outside bets are popular because they’re easy to understand and quick to place. Each bet type follows straightforward rules and fixed payouts, which we’ll detail in the sections that follow.
Types Of Outside Bets In Roulette
Outside bets give you several simple choices, each covering multiple numbers and offering a predictable payout. These bets tend to have higher chances of winning than single-number bets but pay out less when they do. Below are the main types, with the typical payout and the probability on a European wheel (single zero).
Red Or Black Bets: How Do They Work?
A red or black bet covers all numbers of the chosen colour. Place your chip on “Red” or “Black” on the table. If the winning number is the colour you picked, you win.
This is an even-money option, so wins double your stake. Remember that the zero is neither red nor black, so it causes a loss on these bets.
Payout: 1 to 1
Odds (European roulette): 18/37 (about 48.6%)
Odd Or Even Bets: What Should You Know?
This bet covers whether the winning number is odd or even. Put your chip on the “Odd” or “Even” box. If the spun number matches your choice, you receive an even-money return.
As with colour bets, a zero does not count as either odd or even and results in a losing outcome for this bet.
Payout: 1 to 1
Odds (European roulette): 18/37 (about 48.6%)
High Or Low Bets: What Are The Choices?
High/low bets cover one of two number ranges. Place your chip on “1–18” or “19–36” to back one of these ranges.
The two choices are:
- Low: 1–18
- High: 19–36
These are also even-money bets, and the zero again causes a loss for both options.
Payout: 1 to 1
Odds (European roulette): 18/37 (about 48.6%)
Dozen Bets: Payouts & Odds
Dozen bets cover 12-number groups. They let you back a larger block of the layout rather than individual numbers, which gives a balance between coverage and payout.
The possible dozens are:
- 1–12
- 13–24
- 25–36
Payout: 2 to 1
Odds (European roulette): 12/37 (about 32.4%)
Column Bets: Payouts & Probabilities
A column bet selects one of the three vertical columns of numbers on the table. Each column contains 12 numbers and pays the same as a dozen, offering similar coverage but a different way to place your stake on the layout.
Payout: 2 to 1
Odds (European roulette): 12/37 (about 32.4%)
If you prefer straightforward play, even-money bets like red/black or odd/even keep things simple, while dozens and columns offer a middle ground between coverage and payout. All outside bets are affected by the single zero, which keeps the house edge in place.
What Are The Payouts For Outside Bets?
Outside bets have fixed payouts that stay the same each spin under standard European roulette rules. Knowing these helps you weigh potential returns against the probability of winning.
Typical payouts:
- Red or Black: 1 to 1
- Odd or Even: 1 to 1
- High or Low (1–18 or 19–36): 1 to 1
- Dozen (1–12, 13–24, or 25–36): 2 to 1
- Column: 2 to 1
A 1 to 1 payout means you receive your original stake back plus an amount equal to that stake when you win. A 2 to 1 payout means you receive your stake back plus twice the stake when that bet wins.
These payouts reflect the balance between the number of covered outcomes and the table’s edge, and they do not change from round to round. They do not eliminate the house edge, so over many spins the casino advantage remains.
Bear the fixed nature of these payouts in mind when sizing your bets and planning your play. Gamble responsibly and only wager what you can afford to lose.
How Do The Odds For Outside Bets Compare?
Each outside bet covers a specific number of possible winning outcomes, which determines its probability. On a European roulette wheel there are 37 pockets, so the coverage of each bet can be expressed as a simple fraction of that total.
- Even-money bets cover 18 of the 37 numbers, giving roughly a 48.6% chance of winning and a typical payout of 1 to 1.
- Dozens and columns each cover 12 of the 37 numbers, so their chance sits around 32.4% and they usually pay 2 to 1.
Odds are a static description of how often a particular result should occur in theory; they do not change because of previous spins. The house edge on a single-zero European wheel remains about 2.7%, which affects long-term returns regardless of which bets you make.
Understanding these figures helps set realistic expectations for returns and variance. With that clear, you can decide whether you prefer steadier, lower-payout bets or the higher-risk, higher-reward options found among inside bets.
Winning Chances: Are Outside Bets Better Than Inside Bets?
Outside bets generally offer higher chances of winning than most inside bets. For context, a straight-up inside bet on a single number wins about 1 in 37 spins on a European roulette wheel (roughly 2.7%), while outside bets like red/black win on 18 out of 37 outcomes (about 48.6%). Dozens and columns fall between the two extremes, covering 12 numbers each and succeeding about 12 out of 37 spins (around 32.4%).
Choosing between outside and inside bets is essentially a trade-off between probability and payout. Outside bets return less per win but win more often. Inside bets pay more but win less frequently. Think about the experience you want and set your stakes accordingly:
- More regular, smaller wins and steadier play.
- Less frequent, larger wins with higher volatility.
Bear in mind that the long-term house edge on a single-zero (European) roulette wheel remains the same across most bet types, because of the single zero. The percentages above are theoretical odds based on a perfectly random wheel and many spins, so short-term results will vary.
Always gamble responsibly. Play within limits you can afford and view outcomes as entertainment rather than a way to make money.
Common Myths About Outside Bets
There are a few recurring misconceptions worth debunking. One is the gambler’s fallacy: the belief that outcomes are “due” after a streak. In reality, each spin is independent and governed by the wheel’s random outcome; a previous run of reds or blacks does not change the probability of the next spin.
Another myth is that any betting system can overcome the house advantage. Betting systems may alter the pattern of wins and losses or the size and timing of stakes, but they cannot change the underlying probabilities or the house edge. Over the long run, the mathematical expectation remains with the house.
Misperceptions often come from how people interpret short sequences of results and look for patterns where none exist. Cognitive biases, such as seeing streaks as meaningful or assuming short-term trends will continue, make random sequences feel non-random.
Understanding a couple of key points helps avoid misunderstandings about what the numbers mean:
- Each spin is independent; past results do not influence future outcomes.
- Betting systems can affect variance and bankroll management but cannot alter odds or the long-term house advantage.
Remember that gambling carries financial risk. Playing responsibly and recognising the limits of what systems and strategies can achieve are important parts of making informed choices.
Choosing The Right Outside Bet For You
Picking an outside bet depends on what you want from a session. If you enjoy frequent small wins and steady pacing, even-money bets are suitable. If you prefer covering a segment of the table with a better payout than even-money bets, dozens or columns may be more appealing.
Set a budget that matches your tolerance for variance and choose bets that fit that budget. Many platforms provide account tools such as deposit limits, session reminders and self-exclusion options; these can help you stay within the boundaries you decide on before you play.
Whichever outside bet you favour, the key is to play with clear expectations and in control. That way the experience stays enjoyable and predictable in terms of how you manage your time and money.
Most players find that understanding the odds and payouts makes the game more engaging. If you want to try these bets, pick one that matches your play style and stick to the limits you set for yourself.
