# Bets, Wheel Design, and the House Advantage in Single-Zero Roulette

Roulette with a Single ZeroThere are two distinct varieties of roulette wheel, one with a single zero and the other with two. There is no comparison between the two, as the house edge in single-zero roulette is substantially lower, resulting in bigger payouts for the gambler.

In many regions of the world, including much of Europe, single-zero roulette wheels are the norm. Roulette with a single zero is also available in the United States, however it is usually reserved for high rollers.

There are two variants of the game, one in Europe and one in France, where a single 0 is used. Below, we’ll compare and contrast the two roulette wheel designs and outline the various betting possibilities available to you.

## The Rules of Single-Zero Roulette

A roulette wheel with a single zero has 37 betting positions.

Slots range in number from 1 to 36, including an extra slot marked 0. The zero slot is green, while the other numerals will cycle through red and black. The distribution of numbers on a roulette wheel with a single zero is calculated so that the total of a group of numbers in one region of the wheel is roughly equivalent to the sum of a group of numbers in another area of the wheel of the same size.

## Bets on a Single-Zero Roulette Wheel

Gambling on Roulette’s Single ZeroWhen playing roulette, there are two types of wagers: inside and outside. As you will see in the sections that follow, both the rules of roulette and the strategies for placing winning bets in roulette are simple.

Individual numbers on the roulette wheel are what are known as “inside bets.” To place an outside bet, choose a cluster of numbers that is not in the center of the layout.

The straight bet, also known as a single bet, involves placing your chips on a single number and is the most common type of inside bet.

You may also make bets on two neighboring numbers (a “split bet”) or four numbers (a “corner bet”) connected in a square formation. Street bets, which include wagering on a whole row, are also available. The basket bet is the last inside wager and encompasses the digits 0, 1, 2, and 3.

Keep in mind that the 35:1 payoff on a single wager in roulette is the largest of any bet type.

## Outside Bets – These wagers encompass a broader range of possible outcomes.

Bets on whether the ball will fall on red or black, which pay even money, are the most common type of outside wager. You may also double your money if you wager on odd or even, 1-18, or 19-36. Column and dozen bets, both found on the table’s outer rim, offer payouts of 2 to 1 and cover groupings of numbers between 1 and 12 and between 13 and 36, respectively.

## Wheel Configuration for Single-Zero Roulette

There is no difference in wheel configuration between European and French roulette because both versions only have a single zero. All of these betting possibilities are available in European roulette, whereas some are only available in French roulette (though you may find them in some variants of European roulette, especially when playing roulette online).

## Variations on French Roulette

You can put what are called “call bets” on certain segments of the roulette wheel.

These are “le tiers du cylindre,” which includes the twelve digits directly opposite the zero, “voisins du zero,” which includes the eight digits on either side of the zero, and “orphelins,” which includes the remaining eight digits. Bets that are called or publicized are also known as call bets.

## En Prison and La Partage

Cage regulation enWhen the ball lands in the zero slot, this rule only applies to even money bets (red/black, odd/even, etc.). Only one of these two guidelines will be in effect at any given table. The La Partage rule states that the player will receive a return of half of their original wager. The stake is held until the following spin is completed, as per the En Prison regulation. If the spin wins, the player gets his or her money back and the house keeps the rest.

## Probabilities in a Single-Zero Roulette Game

If you want to increase your chances of winning in roulette, it’s best to play European roulette, where the house edge is only 2.70%.

You may improve your roulette odds by playing French Roulette and betting on an even money shot, when the house edge is only 1.35%. Any wagers that aren’t exactly even money will not benefit from the reduced house edge. If you’re given the choice between single-0 and double-0 roulette, go with the latter. The house edge in double-zero roulette is 5.26 percent. You may play French, European, or American roulette at many different online casinos, but we recommend the French version.

The house edge in a game of double-zero roulette is 5.26%, thus it’s best to stick to the single-zero version whenever possible.
