The Ultimate Guide to Roulette: Betting on Every Number and More

Roulette is a classic game that has captivated casino-goers for centuries. Its simplicity, combined with the thrill of chance, makes it a favorite among both novice and experienced players. One question that often comes up among roulette enthusiasts is whether it's possible or advisable to bet on every number in the game. In this comprehensive guide, we'll delve into that question and explore the nuances of roulette betting strategies, the structure of the roulette table, and the odds associated with different types of bets.

Understanding the Roulette Table

The roulette table, or layout, is where players place their bets. It is divided into two sections: the "inside" and the "outside." The inside section contains individual numbers, while the outside section features grouped bets like red or black, odd or even, and high or low.

The Intricacies of the Roulette Wheel

The roulette wheel is the centerpiece of the game. It features numbered pockets that alternate in color between red and black. However, the arrangement of these numbers is not sequential. The design is meant to increase the game's unpredictability. In American roulette, the wheel has 38 pockets, including a single zero (0) and a double zero (00). In contrast, the European roulette wheel has one less pocket, due to the absence of the double zero.

The Role of the Roulette Ball

The roulette ball, a small sphere of ivory or plastic, is a crucial element in the game. It is set into motion in the opposite direction of the spinning wheel. The pocket in which the ball eventually lands determines the winning number.

Decoding Roulette Chips

At a roulette table, players use special roulette chips, not regular casino chips. Each player gets chips of a unique color to avoid confusion. These chips have no value outside the roulette table, so players must exchange them for regular casino chips before leaving the table.

The Two Main Types of Roulette Bets

Roulette bets are categorized into two main types: inside bets and outside bets.

Inside Bets

Inside bets involve betting on specific numbers or small groups of numbers. They offer higher payouts due to their lower probability of winning. Types of inside bets include:

  • Straight Up: A bet on a single number.
  • Split Bet: A bet on two adjacent numbers.
  • Street Bet: A bet on three consecutive numbers.
  • Corner Bet: A bet on four numbers that form a square.
  • Line Bet: A bet on six numbers in two adjacent rows.

Outside Bets

Outside bets are wagered on larger groups of numbers or on certain properties of the numbers like color or parity (odd or even). Although they offer lower payouts, they have higher chances of winning. Types of outside bets include:

  • Red or Black: A bet on the color of the winning number.
  • Odd or Even: A bet on whether the winning number will be odd or even.
  • High or Low: A bet on whether the winning number will fall in the lower half (1-18) or the higher half (19-36) of the possible outcomes.
  • Dozen Bet: A bet on one of the three groups of 12 numbers.
  • Column Bet: A bet on one of the three vertical columns of numbers.

The Concept of Betting on Every Number in Roulette

In theory, it is possible to bet on every number in roulette. However, this strategy is generally considered impractical and unprofitable.

The Logic Behind Every Number Betting

The idea behind betting on every number is to increase the chances of winning each spin. With this strategy, you would indeed win on each spin, but you would also lose money. That's because the total amount you spend on bets would exceed the amount you win.

Calculating the Profitability of Every Number Betting

Let's consider a scenario where you bet $1 on each of the 38 numbers in American roulette. If the ball lands on any number, you would win $35 (the payout for a straight-up bet), but you would lose $37 (the total amount wagered), resulting in a net loss of $2.

Alternative Roulette Betting Strategies

Rather than betting on every number, players often use specific roulette betting strategies to increase their chances of winning.

The Martingale Strategy

The Martingale strategy involves doubling your bet after every loss. The idea is that a win will eventually occur, recouping all previous losses and yielding a small profit.

The Fibonacci Strategy

The Fibonacci strategy involves betting in a sequence where each number is the sum of the two preceding ones (e.g., 1, 1, 2, 3, 5, 8, 13, and so on). After a loss, you move one step forward in the sequence, and after a win, you move two steps backward.

The D'Alembert Strategy

The D'Alembert strategy involves increasing your bet by one unit after a loss and decreasing it by one unit after a win.

The House Edge in Roulette

The house edge refers to the mathematical advantage the casino has over the players. In American roulette, the house edge is approximately 5.26%, while in European roulette, the house edge is significantly lower at about 2.7%. This difference is due to the extra double zero pocket on the American roulette wheel.

Roulette Variations and Their Impact on Betting Strategies

The type of roulette you choose to play can affect your betting strategy.

American Roulette

American roulette has a higher house edge due to the presence of the double zero pocket. This variation favors outside bets over inside bets due to the increased probability of winning.

European Roulette

European roulette, with its single zero, offers better odds for players, making it a more appealing option for both inside and outside bets.

French Roulette

French roulette is similar to European roulette but includes two additional rules that can further decrease the house edge. The "La Partage" rule returns half of even-money bets if the ball lands on zero, and the "En Prison" rule allows players to leave their bet in place for the next spin if the ball lands on zero.


While it may be tempting to bet on every number in roulette, this strategy is typically unprofitable due to the nature of the game's payouts and the house edge. Instead, understanding the rules, the odds, and applying sound betting strategies can improve your chances of winning and make your roulette experience more enjoyable. Whether you're a newcomer or a seasoned player, the world of roulette offers endless excitement.
