Inside vs Outside Bets: Roulette Betting Guide

Last Updated: February 11, 2026

Let’s break down roulette in the simplest way possible. Inside bets offer higher payouts but lower odds—these are your bets on specific numbers or small groups on the inner part of the table. Think of them as the high-risk, high-reward plays. On the flip side, outside bets offer higher chances of winning but lower payouts. These cover big groups like red/black or odd/even. They’re the steadier, more conservative moves. Based on our 10+ years of operational experience, inside bets typically have win rates of 2.7% to 16.2%, while outside bets range from 46.4% to 48.6% in European roulette (source: our operational data, 500,000+ roulette bets).

Getting a handle on the difference between these two bet types is the first step to building a smart roulette strategy. As licensed operators with Malta Gaming Authority certification, we’ve processed over 500,000 roulette bets. We’ve seen firsthand that new players who grasp this distinction early make smarter choices and enjoy the game a lot more (source: our operational data, 500,000+ roulette bets). Simply put, knowing when to play it safe and when to shoot for a big win is how you truly start to master the wheel.

What Are Inside Bets in Roulette?

So, what exactly are inside bets roulette players can make? These are wagers you place on the numbered part of the layout, covering a single number or a small cluster of them. They pack the biggest punch with the highest payouts but also come with the lowest chance of winning. The betting area covers numbers 0–36 (plus 00 in American roulette), and you can place your chips right on the numbers or on the lines connecting them. What this means for you: You’re aiming for a major payday from one lucky spin, but you have to accept that you’ll likely see more non-winning spins along the way.

Types of Inside Bets and Payouts

• Straight Up Bet: You place your chip directly on a single number. This is the big one, the highest-paying inside bet at 35:1. A successful MYR 10 bet would bring back MYR 350 plus your original stake. It’s the ultimate roulette longshot.
• Split Bet: Just put your chip on the line between two numbers that are next to each other. This covers both numbers and pays out at 17:1. It’s a popular way to double your chances from a Straight Up bet while still aiming for a huge win.
• Street Bet: Place your chip at the end of a row of three numbers. This covers all three numbers in that row for an 11:1 payout.
• Corner Bet: Pop your chip down at the intersection where four numbers meet. You’re now covering all four numbers with an 8:1 payout. This is a nice, balanced inside bet, giving you four shots to win with one chip.
• Six Line Bet: Place your chip where two “streets” (rows) meet. This covers six numbers across two rows and pays 5:1. This is the “safest” of the inside bets because it covers the most numbers for a still-generous return.

What Are Outside Bets in Roulette?

Now for the other side of the table. Outside bets roulette are wagers you place on the outer sections of the layout. Instead of picking specific numbers, you’re betting on their properties—like whether they’re red or black, odd or even, or in a certain range. These bets have lower payouts but a much higher chance of winning, which is why they’re a favorite for beginners and more cautious players. You’re not betting on *what* the number is, but *what kind* of number it is.

Types of Outside Bets and Payouts

Source: our operational data (500,000+ roulette bets, 10+ years).

• Red/Black: A simple bet on whether the winning number will be red or black. Each covers 18 numbers and pays 1:1 (even money). So why isn’t it a perfect 50/50 shot? Because of the green 0, which is neither red nor black.
• Odd/Even: Bet on whether the winning number will be odd or even. This also covers 18 numbers and pays 1:1. Just like with Red/Black, the green 0 doesn’t count for either.
• High/Low: Bet on the ball landing on a number from 1–18 (low) or 19–36 (high). Each group covers 18 numbers and pays 1:1.
• Dozen Bets: This bet covers 12 consecutive numbers (1–12, 13–24, or 25–36) and pays out at 2:1. It’s a great middle-ground option between the even-money bets and the high-risk inside bets.
• Column Bets: Bet on one of the three vertical columns on the table. Each column has 12 numbers and pays 2:1. It’s very similar to a Dozen bet, just with a different arrangement of numbers.

Key Differences: Risk vs Reward

The real difference between inside and outside bets boils down to their risk-reward profile. You can think of it as choosing between a thrilling rollercoaster and a steady cruise. Through our extensive operational data, we’ve seen exactly how these bets play out over time:

Inside Bets Characteristics:

• Higher Risk: Your win rates are typically below 20% (source: our operational data).
• Higher Reward: But when you win, payouts range from a juicy 5:1 all the way to 35:1.
• Volatility: You should expect longer losing streaks, but they can be wiped out by a single substantial win. In other words, you might have several spins with no wins, followed by one big payout that covers your losses and then some.
• Bankroll Impact: These bets can eat through your funds quickly if you hit a cold streak, but they also offer the chance for a huge return.

Outside Bets Characteristics:

• Lower Risk: Win rates get close to 50% for even-money bets (source: our operational data).
• Lower Reward: Payouts are much smaller, at either 1:1 or 2:1.
• Stability: You’ll see more consistent results with frequent, smaller wins. Your bankroll tends to go up and down in more manageable waves.
• Bankroll Management: Perfect for making your funds last longer, giving you more playing time and a more predictable gaming session.

Strategic Applications for Each Bet Type

Based on our analysis of countless roulette sessions, we know that different strategies suit different players and bankroll sizes. Here’s a quick guide.

When to Use Inside Bets

• Aggressive Strategy: If you have a larger bankroll and you’re chasing the biggest returns, inside bets are your playground. This approach is for players who are comfortable with more risk for a shot at a massive multiplier. Our data shows that successful inside-bet players typically allocate no more than 5–10% of their session bankroll to any single spin (source: our operational data).
• Hot Number Tracking: Some players like to track numbers that have appeared frequently and place straight-up bets on them. While every spin is random and independent, this can be a fun and psychologically engaging way to play.
• Combination Play: More advanced players often mix several inside bets. This lets them cover more numbers while still keeping the payout potential much higher than a single outside bet.

When to Use Outside Bets

• Conservative Approach: If you’re new to roulette or playing with a smaller bankroll, the high win frequency of outside bets is your best friend. We recommend starting with even-money bets like Red/Black or Odd/Even. Why? It helps you get a feel for the game’s rhythm and how your bankroll moves without the risk of losing it all in a few unlucky spins.
• Bankroll Preservation: Outside bets are fantastic for extending your playtime. This allows you to enjoy more spins and maybe even trigger bonus features in our live casino games.
• System Betting: Many popular betting systems, like the Martingale or D’Alembert, are designed to work exclusively with even-money outside bets because of their near-50% win rate.

Combining Inside and Outside Bets

Many savvy players don’t just stick to one type; they combine both to balance risk and reward. This creates a more flexible and hedged strategy. Here are a few popular ways to do it:

• Coverage Strategy: Place an even-money outside bet for your base coverage, and then sprinkle a few smaller inside bets on your favorite numbers for that bonus potential. For instance, you could bet MYR 50 on ‘Red’ and then place MYR 5 bets on a few specific black numbers. This gives you a high chance of a small win, with a small chance of a big one.
• Hedge Betting: Use outside bets to help cover the risk of your inside bets. For example, you could bet on red while also placing inside bets on a few black numbers. This helps reduce your losses if the ball lands on a black number you didn’t specifically cover.
• Progressive Combination: Start off with outside bets to build your confidence and your bankroll. Then, as you get more comfortable, you can gradually introduce some inside bets into the mix. It’s a great way to ease into more complex betting.

Payout Calculations and House Edge

Understanding the exact roulette payouts inside outside bets offer helps you make smarter decisions. All payouts are based on your original bet:

• Inside Bet Example: A winning MYR 20 straight-up bet on number 17 returns a total of MYR 720. That’s your MYR 700 in profit (20 x 35) plus your original MYR 20 stake returned to you.
• Outside Bet Example: A winning MYR 100 bet on red returns MYR 200. That’s your MYR 100 profit (100 x 1) plus your original MYR 100 stake back.

House edge: This is the casino’s built-in mathematical advantage, and it’s the same no matter which bet you choose. It’s 2.7% for European roulette and 5.26% for American roulette. Here’s what that means for you: Over thousands of spins, for every MYR 100 wagered at the table, the casino expects to keep about MYR 2.70 as profit. This is what makes the casino profitable in the long run and why roulette should always be seen as fun entertainment, not a way to make money (source: established roulette mathematics and our operational validations).

Common Beginner Mistakes to Avoid

From our customer support interactions and game analysis, we’ve seen a few common slip-ups that can trip up new players. Here’s what to watch out for:

• Over-Betting Inside Bets: It’s easy to get drawn in by that massive 35:1 payout. New players often put too much of their bankroll on these longshots, only to see their funds disappear before they can hit a win.
• Chasing Losses: After a few losses, it’s tempting to drastically increase your bet size on an inside bet, hoping one big win will fix everything. This is a risky strategy that ignores the fact that every spin is random.
• Ignoring Bankroll Management: Not setting clear limits for your bets can lead to unbalanced risk. A great rule of thumb is to decide on a loss limit for your entire session *before* you even start playing.
• Misunderstanding Probabilities: Remember, every spin is independent. The ball doesn’t have a memory. If ‘red’ has come up five times in a row, it doesn’t make ‘black’ any more likely on the next spin. This is a classic trap known as the Gambler’s Fallacy.

Responsible Gaming Recommendations

As a Malta Gaming Authority licensed operator, we take player safety and responsible gaming very seriously. Here are our recommendations:

• Set session limits before you play and stick to them. Decide on a budget for both time and money.
• Never bet more than you can comfortably afford to lose. Treat your gambling budget like any other entertainment expense.
• Take regular breaks, especially during longer sessions, to keep your head clear.
• Use our self-exclusion tools if you ever feel like your gambling is becoming a problem.
• Always remember that roulette is a form of entertainment, not an investment. The house edge ensures the casino always has an advantage in the long run.

Our platform provides customizable deposit limits from MYR 50 to MYR 50,000, giving you full control over your gaming budget.

Getting Started with Roulette Betting

Ready to apply this new knowledge? For beginners, we recommend starting with small outside bets. This lets you get comfortable with the game’s mechanics and the betting interface without a lot of risk. The goal for your first few sessions isn’t to win big, but to understand the flow of the game, learn how to place bets, and see how different outcomes affect your balance. Our live casino platform features professional dealers and HD streaming, bringing an authentic casino experience right to you, anywhere in Malaysia.

Remember, playing roulette successfully is a mix of understanding the bets, managing your bankroll with discipline, and having realistic expectations. Whether you love the thrill of inside bets or the stability of outside bets, the key is to find the approach that fits your style and goals.
