Since its invention in the 18th century, roulette has enthralled millions of players globally — from the opulent casinos of Monte Carlo to modern online gambling platforms.

What is a Roulette Game and How Does It Work?

Roulette is a chance-based casino game where players bet on where a ball will land on a spinning wheel. The wheel is divided into numbered pockets, each colored red, black, or green, depending on the version of the game.

How Does Roulette Work?

The game begins with players placing their bets on the table layout, which displays numbers and groups of numbers in various configurations:

  • Inside Bets: Bets on specific numbers or small clusters of numbers.

  • Outside Bets: Bets on broader categories like color, odd/even, or dozens.

Once betting is complete, the dealer spins the wheel in one direction and rolls the ball in the opposite direction along the wheel’s rim. After a few revolutions, the ball loses momentum and falls into one of the numbered pockets. The dealer announces the winning number and color, and winning bets are paid out accordingly.

However, like any casino game, Roulette has its ups and downs. Here is a quick breakdown of the pros and cons to help you decide if it is the game for you:

ProsCons
Easy to learn and playThe house edge ensures long-term losses
Wide variety of betting optionsGame outcomes are entirely luck-based
Fast-paced and exciting gameplayCan be addictive without careful bankroll management
Available in both land-based and online casinosCertain bets offer low odds of winning
Multiple versions offering different oddsNo player skill can influence the outcome

Different Versions of Roulette Explained

Roulette has evolved into several versions, each with its unique characteristics, rules, and odds. The main types include:

  • European Roulette

  • American Roulette

  • French Roulette

  • Russian Roulette (non-casino, dangerous game, explained separately)

Types of Roulette

Each roulette type varies primarily by the number of pockets on the wheel and house edge, which affects player odds and strategy.

What is European Roulette?

European Roulette is widely regarded as the most player-friendly version of roulette. It has 37 pockets, numbered 1 through 36 plus a single zero (0). This single zero reduces the house edge to about 2.7%, better than the American version.

The numbers alternate between red and black, with zero colored green. The European Roulette wheel and table layout follow a specific design to balance the game.

European Roulette is popular in most casinos worldwide and is considered the best roulette version for players who want a better chance of winning.

What is American Roulette?

American Roulette includes an extra pocket — the double zero (00) — making for 38 pockets in total. This increases the house edge to around 5.26%, nearly double that of European Roulette.

The presence of the double zero reduces player odds, which is why many players prefer European Roulette or French Roulette, if available.

What is French Roulette?

French Roulette is essentially European Roulette but with additional rules that favor the player, such as La Partage and En Prison:

  • La Partage: If the ball lands on zero, players lose only half of their even-money bets.

  • En Prison: Even-money bets remain "imprisoned" for the next spin if zero appears, potentially giving the player another chance to win.

These rules reduce the house edge further, sometimes down to around 1.35%, making French Roulette the most favorable version for players.

What is the Russian Roulette Game?

It’s important to clarify that Russian Roulette is NOT a casino game. Instead, it is a deadly game of chance involving a revolver loaded with a single bullet. Players take turns spinning the cylinder and pulling the trigger while pointing the gun at their own heads.

This game is extremely dangerous and life-threatening, bearing no relation to the casino game of roulette. It’s often referenced in movies and literature as a symbol of high risk and fate.

One of the most exciting aspects of roulette is the variety of bets available, each with different odds and payouts. These bets fall into two main categories:

  • Inside Bets: Placed on specific numbers or small groups of numbers inside the numbered grid.

  • Outside Bets: Placed on larger groups like colors or dozens, typically offering better odds but lower payouts.

Inside Bets Explained

  • Straight Up: Betting on a single number. Payout is 35:1.

  • Split Bet: Betting on two adjacent numbers, either vertically or horizontally. Payout is 17:1.

  • Street Bet: Betting on a row of three numbers. Payout is 11:1.

  • Corner Bet: Betting on four numbers that form a square. Payout is 8:1.

  • Line Bet: Betting on six numbers covering two adjacent rows. Payout is 5:1.

Outside Bets Explained

  • Red or Black: Betting on the color of the winning number. Payout is 1:1.

  • Odd or Even: Betting on whether the number will be odd or even. Payout is 1:1.

  • High or Low: Betting on numbers 1-18 (low) or 19-36 (high). Payout is 1:1.

  • Dozens: Betting on one of three groups of 12 numbers: 1-12, 13-24, or 25-36. Payout is 2:1.

  • Columns: Betting on one of three vertical columns of 12 numbers each. Payout is 2:1.

What is Street Bet in Roulette?

A street bet is an inside bet where you wager on three consecutive numbers in a single horizontal row on the table layout.

  • For example, betting on the numbers 1, 2, and 3 as a group.

  • The payout for a street bet is 11:1.

  • This bet increases your chance of winning compared to a straight-up bet, but with a lower payout.

  • To place a street bet, chips are placed at the end of the row, covering all three numbers.

Street bets offer a good balance of risk and reward for players looking for a middle ground between single-number bets and larger outside bets.

What is the Payout on Roulette?

The payout on roulette varies depending on the type of bet you place, reflecting the level of risk and the number of possible winning numbers covered by your wager. The highest payout is for a straight-up bet, where you bet on a single number; if the ball lands on that number, you win 35 times your original stake (35:1). Bets covering two adjacent numbers, known as split bets, pay 17:1, while street bets (covering three numbers in a row) pay 11:1. Larger inside bets like corner bets (four numbers) and line bets (six numbers) offer payouts of 8:1 and 5:1, respectively. Outside bets, which cover broader categories like red or black, odd or even, and high or low numbers, generally pay even money (1:1) due to their higher chances of winning. Bets on dozens or columns, which cover 12 numbers, pay 2:1. Understanding these payouts helps players weigh their risk against potential rewards and choose betting strategies that suit their play style.

Roulette’s global popularity can be attributed to several factors that make it both accessible and exciting:

  • Simple Rules: Easy for beginners to understand and play without a steep learning curve.

  • Multiple Betting Options: Cater to different types of players — risk-takers or conservative bettors.

  • Visual and Sensory Appeal: The spinning wheel, clicking ball, and colorful table create a captivating experience.

  • Social Atmosphere: Often played in lively casino settings where players interact and share the thrill.

  • Historical Prestige: Roulette is synonymous with glamour, casinos, and entertainment culture.

  • Online Availability: Roulette is available on nearly all online gambling platforms, accessible 24/7.

  • Potential for Big Wins: Even a small bet on a single number can lead to large payouts.

What makes roulette popular worldwide is its perfect blend of simplicity, excitement, and variety. The game’s easy-to-understand rules invite players of all skill levels to participate, while the spinning wheel and bouncing ball create a thrilling atmosphere that keeps players on the edge of their seats. Roulette offers a wide range of betting options, catering to both cautious players and high-risk gamblers, making it accessible and appealing to a broad audience. Its rich history and association with glamorous casinos add to its allure, while the availability of online versions allows people from all over the world to enjoy the game anytime, anywhere.
