Roulette Strategy – Best Roulette Bets & Systems

A roulette strategy is a system that determines where to place your bets, how much to stake, or both. For centuries, gamblers have tried to answer the questions, “How do you win online roulette bets consistently?” and “What’s the best mathematical roulette strategy?”.

Some claim to have found the answer, believing they can increase long-term winning chances. In this guide, you’ll explore the most popular roulette systems, What the best roulette strategies are to win money, how they work, whether they suit your play style, and if they truly improve your odds.

Roulette Strategies & Systems

What is a roulette strategy? It is a way of betting that aims to improve your long-term expected value (EV). Expected value is the amount of money you stand to win over the long run. It’s based on the probability of a bet hitting (i.e. its odds) and your stake. A roulette strategy aims to maximize your EV in every situation.

One of the main ways to implement a strategy in roulette is to use a betting system. Popular roulette systems such as the Martingale or Fibonacci are designed to be used on even-money bets such as red or black.

We’ve listed the best strategies for roulette, based on popular opinion, and how to use them at the top offshore casino sites in the following sections.

Martingale system

Martingale System

The roulette strategy Martingale was developed by Paul Pierre Levy. It’s often cited as the best way to win at roulette, but is it? The Martingale system is one of the easiest to implement, as it simply requires you to double your bet size after a loss and reset after a win.

For example, if your starting stake is $10, you lose the first bet, so your second bet is $20. If you lose again, your third bet becomes $40. If you win the third bet, you’ll net $80, which gives you a $10 profit. Your profit will always be equal to your starting stake. After a win, you reset, so your fourth bet would return to $10.

Theoretically, this system guarantees a profit, assuming an unlimited bankroll and no table limits. In reality, both are constrained, and you may hit the table limit or deplete your bankroll before achieving success. As your stakes rise exponentially, even a brief losing streak can lead to massive bets, making this system highly risky.

For instance, if your starting stake is $10 and you lose 6 hands in a row, you would have lost a total of $630 and would need to risk $640 on your 7th bet. Even if you win the 7th bet, your total risk would have been $1,270, and your profit would only be $10.

Here’s a more detailed example of how the system might play out over 10 bets, starting with a $5 stake:

Bet Number Stake Win/Loss Total Profit
1 $5 Loss -$5
2 $10 Loss -$15
3 $20 Win +$5
4 $5 Win +$10
5 $5 Loss +$5
6 $10 Loss -$5
7 $20 Loss -$25
8 $40 Win +$15
9 $5 Win +$20
10 $5 Loss +$15

Pros:

  • Mathematically sound betting strategy
  • Easy roulette system to understand
  • Can be used in live and online roulette games
  • Theoretically guarantees profit

Cons:

  • Becomes expensive after consecutive losses
  • House limits prevent the system from working
Paroli System

Paroli System

Paroli is the opposite of the Martingale. So, instead of doubling the size of your bet after a loss, you do it after a win. This makes it a positive progression roulette system. So, let’s say you bet $5 and win, the next bet you’ll make is $10. You win again, so your third bet is $20. You lose the fourth bet, so you reset to $5.

Like the Martingale, the Paroli roulette betting system is mathematically sound. However, according to MIT research, it’s not the best mathematical roulette strategy.

Based on 100,000 data sets and a game with no house edge, Paroli betting makes you 15% more likely to lose. That’s something you want to avoid if you’re thinking about how to beat roulette.

The table below shows how utilizing the Paroli system might look over 10 rounds:

Bet Number Stake Win/Loss Total Profit
1 $5 Loss -$5
2 $5 Loss -$10
3 $5 Win -$5
4 $10 Win +$5
5 $5 Loss 0
6 $5 Loss -$5
7 $5 Win 0
8 $10 Win +$10
9 $20 Win +$30
10 $5 Loss +$25

Pros:

  • You start with a small initial bet
  • You only increase your bet when you win
  • Easy roulette system to utilize
  • Capitalize on winning streaks and minimize losses during losing streaks

Cons:

  • No natural stopping point
  • Bets may become prohibitively expensive
d’Alembert System

d’Alembert System

People often reference the d’Alembert System when they’re discussing how to win at roulette. Like other roulette strategies, d’Alembert is a negative progression system, so you change your bet size following a loss.

The premise is simple: pick an initial betting unit, add one unit if you lose, and reduce your stake by one unit if you win. The d’Alembert is similar to the Martingale system, but it’s more manageable in terms of bet sizing. The fact you’re only increasing by a single unit, rather than doubling your take, makes it more practical.

However, it’s based on the assumption that you’re making a true 50/50 wager. A red/black bet isn’t quite 50/50. Therefore, because you’re getting a true 50/50, this isn’t the best way to win at roulette.

Here’s an example where your initial stake is $5, and you decide on a betting unit of $5.

Bet Number Stake Win/Loss Total Profit
1 $5 Loss -$5
2 $10 Loss -$15
3 $15 Loss -$30
4 $20 Win -$10
5 $15 Win +$5
6 $10 Loss -$5
7 $15 Win +$10
8 $10 Win +$20
9 $5 Loss +$15
10 $10 Loss +$5

Pros:

  • Bet sizing changes after wins and losses
  • Bet changes less dramatic than other systems
  • Works when the odds are 50/50
  • Suitable for all budgets as you can decide the unit size

Cons:

  • Requires a true 50/50 bet to work
  • Based on The Gambler’s Fallacy
Labouchere System

Labouchere System

Labouchere is known as a pseudo-negative progression roulette betting system. It’s described as “pseudo” because you’re not following a set pattern of positive and negative progressions. Bets using the Labouchere system fluctuate based on a sequence of numbers and your results.

You start with a sequence of numbers that add up to the amount you want to win. The sequence must start with an equal number of points. For example, if you want to win $21, your sequence could be 1, 2, 3, 4, 5, 6. Once you’ve got your sequence, you add the first and last numbers together.

If you win, you remove the two numbers from your sequence and move on to the next two. If you lose, you add the bet amount to the end of your sequence.

The table below illustrates an example of the Labouchère system over 10 rounds. Our profit goal is $200, which is represented in the sequence 1-2-4-1-3-3-2-4 (all numbers are multiplied by 10 for simplicity). In this example, once we reach our profit goal, we would either reset the sequence or conclude the session.

Bet Number Stake Win/Loss Sequence Total Profit
1 $50 Win 1-2-4-1-3-3-2-4 +$50
2 $40 Loss 2-4-1-3-3-2 +$10
3 $60 Loss 2-4-1-3-3-2-4 -$50
4 $80 Win 2-4-1-3-3-2-4-6 +$30
5 $80 Win 4-1-3-3-2-4 +$110
6 $50 Loss 1-3-3-2-4 +$60
7 $60 Loss 1-3-3-2-4-5 0
8 $70 Win 1-3-3-2-4-5-6 +$70
9 $80 Win 3-3-2-4-5 +$150
10 $70 Win 3-2-4 +$220

Pros:

  • Allow you to hit a predetermined profit
  • Adds structure to your bet sizing
  • Can be used live or online
  • Less risky than the Martingale system

Cons:

  • Needlessly complex way of sizing your bets
  • Statistics show it makes you 8% less likely to win
James Bond Strategy

James Bond Strategy

The James Bond strategy gets its name from Ian Fleming’s James Bond series, who first introduced the system in Casino Royale. Unlike other betting strategies that focus on bet size, this method is based on bet spread and strategic bet placement.

The goal of the strategy is to cover a large portion of the roulette board by dividing your stake into three specific bets:

  • 70% on High Numbers (19-36)
  • 20% on a Double Street (13-18)
  • 10% on Zero

With this setup, you cover 67.5% of the possible outcomes, increasing your chances of winning. However, this strategy requires a higher initial stake relative to potential winnings.

The James Bond system follows a flat betting approach, meaning your stake remains constant. However, it is often combined with another roulette betting strategy. One of the most popular combinations is with the Martingale system.

While this combination can be effective, it also carries significant risk. Since the James Bond strategy already involves a sizable bet, pairing it with Martingale (which doubles bets after losses) can quickly deplete your bankroll after just three or four consecutive losses.

Pros:

  • Can be used in conjunction with other systems
  • You can cover more than 67.5% of the wheel
  • Flat and progressive betting is available
  • Increases your chances of winning

Cons:

  • Requires a high initial bet relative to the winning amount
  • Can get complicated when combined with progressive betting

Positive Progression vs Negative Progression Systems

Most roulette betting systems don’t dictate where to place your bets when you play at a roulette casino but instead focus on bet sizing. These strategies generally fall into two categories: positive progression and negative progression systems.

Positive progression strategies require you to increase your bet size after a win and either keep it the same or reduce it after a loss. For example, if you start with a $1 bet and lose, your next bet remains $1. If you win, your next bet increases—often to $2, though the exact increase depends on the system.

Negative progression strategies take the opposite approach: you increase your bet after a loss and either repeat or lower it after a win. For example, if you start with a $1 bet and lose, your next bet might be $2. If you lose again, your third bet could rise to $4, following an escalating pattern until you win. Once you secure a win, you either reset your bet to the initial $1 or lower it based on the rules of the chosen system.

Expert Insight
The best strategies for roulette, especially for beginners learning how to play roulette, are positive progression systems. These systems increase bets only after a win, typically risking profits rather than chasing losses (though you may be down before a winning streak starts). In contrast, negative progression systems can quickly drain your bankroll, as they require larger bets during a losing streak and often demand a substantial bankroll to be effective.

Best Roulette Bets & Odds

Roulette systems look great on the surface but are not always practical. You need unlimited resources in this game of chance and no betting restrictions. Plus, you’re counting on having no house edge to make roulette strategies like the Martingale and Labouchere work.

We need to look toward the roulette odds. Specifically, what the odds are for each roulette bet. From this, we can pick out the best roulette bets based on their risk vs. return.

Again, it’s important to stress that the house always has an edge. We can’t show you how to play roulette and win every time because the house always wins. What we can do, however, is use the roulette strategy chart below to identify the least risky bets. Picking these bets is the best way to win at roulette in the short term.

Choosing the Right Roulette Game

Today, there are numerous roulette variants available online, including Bitcoin Roulette, Double Ball, and No Zero, to name just a few. Each variation offers slightly different gameplay, available bets, and house edges (the casino’s advantage). The house edge is crucial in deciding which version to play, as it directly influences your chances of winning.

Among the many variations, the three classic versions—American, European, and French—are the most commonly found at online casinos. Below, you can compare the bets and house edges for each of these variants.

American Roulette

American Roulette - how to play roulette - roulette strategy

The house edge in American Roulette is 5.26%, largely due to the presence of 38 numbers on the wheel, including both a single zero (0) and a double zero (00). The addition of the double zero decreases your chances of winning any bet, as you now have a 1 in 38 chance of hitting a number.

This impact isn’t limited to straight-up bets—all bets, including even-money wagers commonly used in roulette strategies, are affected. The double zero reduces your odds by over 1% on even money bets increasing the house edge significantly compared to other roulette variations.

One advantage of American Roulette over its European and French counterparts is the option to place a “Basket Bet,” which covers the numbers 0, 00, 1, 2, and 3. However, this bet carries a hefty house edge of 7.89%, the highest of any roulette bet. For this reason, it’s generally not in your best interest to place a Basket Bet.

European Roulette

How-to-Play-Roulette-European-Roulette - roulette strategy

The house edge in European Roulette is just 2.7%, which is 2.66% lower than that of American Roulette. While this might seem small, it significantly increases your chances of winning.

The lower house edge is due to the European Roulette wheel having only a single zero, for a total of 37 numbers. Though the payouts remain the same across all bets, the reduced number of pockets means better odds for the player, which is why the house edge is lower in European Roulette.

French Roulette

French Roulette Table

French roulette isn’t as common as the previous variations, but many of the best online casinos offer this variant. The house edge in French Roulette is 1.35%, thanks to a special rule known as La Partage. At its core, French Roulette is the same as its European counterpart because it has the same wheel.

However, the odds are better in French Roulette because La Partage gives players 50% of their bet back if they make an even-money bet and the ball lands on zero. In the context of our discussion on how to win roulette online games, this makes French variants the best option.

Top 5 Roulette Tips

We’ve talked about roulette systems and what the best roulette bets are, so now let’s talk tactics. You can’t devise a roulette strategy to win every time you play because the house has an advantage.

A roulette system such as the Martingale works in theory but falls short in practice because of certain betting restrictions.

What you can do, however, is think logically, play sensibly, and make smart decisions. The following roulette strategy tips give you the best chance of getting maximum value from your time at the table.

Avoid American Roulette

The house edge for American roulette is double what it is for European roulette and over triple of French roulette. So even if you use the best strategy for roulette, playing at American roulette significantly reduces your odds.

There are also many other versions of roulette, such as Lightning Roulette, Double Ball, Min, etc., but check the payouts, RTP, and the probability of the bets you will make before playing to make sure that it’s not lowering your chances of winning.

Play Roulette Responsibly

The best roulette strategy tip we can give you is to play responsibly. Only risk a small percentage of your roulette bankroll in any given session.

Remember not to get carried away by consecutive wins. Even if you make a profit three or four sessions in a row, don’t assume the strategy is foolproof (none are). While it’s okay to slightly increase your stake in proportion to your growing bankroll, avoid going all-in or drastically upping your bets. Stay disciplined and avoid overconfidence.

Use Basic Roulette Strategy

The basic roulette strategy recommends favoring lower-risk bets for the best long-term expected value (EV). As shown in our table earlier, the most favorable bets are red/black, odd/even, and 1-18/19-36. Most strategies are designed for even-money bets, and attempting to apply them to inside bets significantly increases the risk of losses.

Double Your Bets on Dozens and Columns

While most strategies aren’t suited for inside bets, some can be applied to dozens and column bets if you place two bets at a time. Dozen and column bets pay 2:1, so betting on two at a time can lead to a profit. However, to achieve your desired profit, you’ll need to double your stake since your profit will be half of your total bet.

For example, if you stake $5 on 1-12 and $5 on 13-24, your total wager is $10. If any number between 1 and 24 hits, you’ll win $15, giving you a $5 profit where as a $10 outright bet on black/red or odd/even would get you a $10 profit. This strategy spreads your risk while maintaining a balanced approach.

Patterns Don’t Exist

Ask any superstitious gambler how to beat roulette, and they’ll probably say you should look for patterns. However, each roulette spin is an independent event. Previous results have no bearing on future spins, so there aren’t any patterns. Tracking numbers won’t improve your chances, so don’t waste your time. Bet sensibly, try some roulette systems if you’d like, but more than anything, remember to have fun. The game is meant to be enjoyed, not overanalyzed.

What is the Best Roulette Strategy?

As you’ve seen, there are several roulette strategies to choose from. While no roulette strategy guarantees you win money or even reduces the house edge, they can help some players manage their bankroll and avoid emotional betting or chasing losses without a plan.

The best strategy for roulette depends on your play style, bankroll, and goals. High rollers might favor the Martingale system, while beginners can try the low-risk Paroli system. Experienced bettors may combine the James Bond strategy with a progressive system. To find what works, test strategies with low stakes or free play first.
