Roulette

Roulette is one of the most iconic and exciting casino games, known for its spinning wheel, red and black numbers, and the thrill of watching the ball land in a pocket. The game’s appeal comes from its simplicity—players place bets on where they think the ball will land, and winnings are determined by the accuracy of their predictions. Whether you’re playing in a physical casino or online, roulette offers a blend of luck, strategy, and excitement.

Types of Roulette

There are several variations of roulette, with the most common being:

  • European Roulette – The wheel has 37 pockets (numbers 1–36 and a single zero), offering a lower house edge of 2.7%.
  • American Roulette – The wheel has 38 pockets (numbers 1–36, a single zero, and a double zero), which increases the house edge to 5.26%.
  • French Roulette – Similar to European roulette but with additional rules like “La Partage” and “En Prison,” which can reduce the house edge further. The game has been a casino staple for centuries, originating in 18th-century France before spreading worldwide.

Game Mechanics

In online roulette, players bet on where a small metallic ball will land on a rotating wheel divided into numbered slots. The objective is to predict the correct outcome, which may include a specific number, groups of numbers, colours (red or black), or whether the number is odd or even. Players can choose between two main formats:

  • Traditional Online Roulette: Powered by Random Number Generators (RNGs) to ensure fair outcomes, this format is ideal for those who prefer independent play.
  • Live Dealer Roulette: Streams real-time games from a professional studio, featuring live croupiers and allowing interaction with other players. This format mirrors the social aspect of land-based casinos.

How to Play Roulette 

Roulette is easy to understand, making it ideal for beginners. The game follows these steps: 

Step 1: Place Your Bets 

Before the wheel spins, players place chips on the betting table. There are two main types of bets: 

  • Inside Bets – Placed on specific numbers or small groups of numbers. These offer higher payouts but lower odds of winning. Examples:  
    • Straight Up – Bet on a single number (pays 35:1). 
    • Split – Bet on two adjacent numbers (pays 17:1). 
    • Street – Bet on a row of three numbers (pays 11:1). 
  • Outside Bets – Placed on broader categories like red/black, odd/even, or high/low. These offer lower payouts but better odds. Examples:  
    • Red or Black – Bet on the color of the winning number (pays 1:1). 
    • Odd or Even – Bet on whether the number will be odd or even (pays 1:1). 
    • Dozens – Bet on one of three sets of 12 numbers (pays 2:1). 

Step 2: The Dealer Spins the Wheel

Once bets are placed, the dealer spins the roulette wheel in one direction and releases the ball in the opposite direction. Players can place last-minute bets until the dealer announces “No more bets.”

Step 3: Winning Number is Determined

When the ball lands in a numbered pocket, the dealer announces the winning number and colour. Winning bets are paid out according to the odds, and losing bets are cleared from the table.

Step 4: Next Round Begins

Players place new bets, and the process repeats.

Roulette Betting Options

Betting in online roulette adds an element of strategy to the game. Whether you are a seasoned player or new to the game, understanding the range of bets and their associated odds can enhance your chances of success. Roulette bets fall into two main categories, with each offering different risk levels and payouts. Choosing the right strategy depends on your goals—whether you aim for consistent, lower-risk wins or high-reward opportunities.

Players can explore a wide range of betting strategies grouped into two categories:

  • Inside Bets:
    • Straight Up: A single number bet with a payout of 35:1.
    • Split: Bets placed on two adjacent numbers, offering a payout of 17:1.
    • Street: A row of three numbers, with a payout of 11:1.
  • Outside Bets:
    • Red or Black: Betting on the ball landing in a red or black pocket (1:1 payout).
    • Odd or Even: Wagering on whether the number will be odd or even (1:1 payout).
    • High or Low: Predicting if the number will fall between 1-18 or 19-36 (1:1 payout).

Regulation and Fairness

Online roulette is highly regulated in many jurisdictions. Independent auditors test RNGs to ensure randomness, while licensing authorities enforce fair play. Players can trust reputable platforms that clearly display their licensing and regulatory compliance.

Providers and Platforms

The success of online roulette is heavily supported by leading software providers:

  • Evolution Gaming: Known for its state-of-the-art live dealer games, including Lightning Roulette and Immersive Roulette.
  • Microgaming: Offers a wide range of high-quality RNG-based roulette games.
  • NetEnt: Specialises in visually stunning and innovative roulette formats.

Differences Between American, European, and French Roulette

While all variations share the basic mechanics, they differ in wheel layout and rules. European Roulette, with a single zero, offers better odds than American Roulette, which has an additional double zero. French Roulette introduces La Partage and En Prison, unique rules that significantly improve odds for even-money bets.

Wheel Layout

European roulette wheel layout
  • American Roulette: Features 38 pockets, including numbers 1-36, a single zero (0), and a double zero (00). This additional pocket increases the house edge.
  • European Roulette: Contains 37 pockets with numbers 1-36 and a single zero (0). The absence of the double zero reduces the house edge compared to American roulette.
  • French Roulette: Similar to European roulette, it also has 37 pockets (numbers 1-36 and a single zero). However, it includes unique betting options and rules that can further lower the house edge.

Special Rules

  • La Partage Rule (French Roulette): If a player places an even-money bet and the ball lands on zero, they lose only half their stake instead of the full amount. This rule significantly reduces the effective house edge for even-money bets.
  • En Prison Rule (French Roulette): Similar to La Partage, this rule allows players to “imprison” their bet for the next spin if a zero appears. If they win on that subsequent spin, they recover their original stake.

Betting Dynamics in French vs American Roulette

French Roulette favours strategic players, thanks to rules like La Partage, which refunds half the bet when the ball lands on zero. American Roulette, by contrast, appeals to those seeking a higher-risk, higher-reward experience.

Unique Features in Live Dealer Roulette

Live dealer roulette combines the excitement of traditional casino gaming with the convenience of online play, delivering a unique and immersive experience. Here are some standout features that set live dealer roulette apart from standard online roulette games:

Real-Time Interaction

  • Multiple Camera Angles: Many live dealer roulette games use several camera angles to provide a comprehensive view of the action. This feature allows players to see the wheel, ball, and dealer from various perspectives, ensuring transparency and enhancing the overall experience.
  • Live Dealers: Players interact with professional dealers in real time via video streaming. These dealers engage with players, creating an atmosphere reminiscent of a physical casino. The ability to chat with dealers adds a social element, making the game more personal and engaging.
  • VIP Tables: Many live casinos offer exclusive VIP tables with higher betting limits and personalised service. These tables often feature professional dealers and luxurious settings, providing an upscale gaming experience for high rollers.

Roulette Strategy & Tips

While roulette is a game of chance, players can use different strategies to manage their bets and maximize their chances of winning. 

 Understanding the House Edge

  • European roulette offers better odds than American roulette due to having only one zero. 
  • French roulette provides additional rules that lower the house edge even further. 

Betting Strategies

Although no strategy guarantees a win, some systems help manage risk: 

  • Martingale System – Double your bet after every loss to recover previous losses when you win. However, this requires a large bankroll. 
  • Fibonacci System – Follows a sequence where each bet is the sum of the previous two bets. This is a slower progression than Martingale. 
  • D’Alembert System – Increase your bet by one unit after a loss and decrease it after a win, making it a safer alternative. 
  • Flat Betting – Bet the same amount consistently to limit losses and extend playtime. 

Play European or French Roulette

Since American roulette has an extra zero, it increases the house edge. If possible, always choose European or French roulette for better odds. 

Manage Your Bankroll

  • Set a budget before playing and stick to it. 
  • Avoid chasing losses by making reckless bets. 
  • Use outside bets (e.g., red/black, odd/even) if you prefer a safer approach with frequent wins. 

Things to Consider When Playing Roulette

1. The Role of Luck

Roulette is purely a game of chance, and no strategy can change the fact that each spin is independent of the previous one. There’s no way to predict where the ball will land, so it’s important to play for entertainment rather than expecting consistent winnings. 

2. Casino Rules & Table Limits

Different casinos have different table limits and rules. Before playing, check: 

  • The minimum and maximum bet limits
  • Whether the “La Partage” or “En Prison” rules apply (French roulette only). 
  • The type of wheel being used (European vs. American). 

3. Online vs. Live Roulette 

  • Online roulette uses Random Number Generators (RNGs) to ensure fairness. It’s fast-paced and convenient. 
  • Live dealer roulette offers an authentic casino experience with a real dealer spinning the wheel via live streaming.
