Types of Roulette Wheels

Roulette is an old casino game yet its popularity never seem to have waned a bit ever since it was introduced back in the 18th century France. It has attracted countless of gamblers from so many generations, creating a fan base rivalled only by other well-known games such as Poker, Blackjack and slot machine games. Indeed, millions of gambling enthusiasts have already been enamored by roulette, and the numbers never ceased growing.

This reputation lies primarily on the game’s design. Anybody who has played roulette can simply attest to the game’s simplicity, both in its set up and in its very fluid gameplay. The game is so simple that it can be summed up in these three steps: betting, spinning, and winning or losing. In other words, it starts when the player places his or her bets, followed by the spinning of the wheel and ball by the dealer, after which the winning bet is decided by wherever the ball lands.

The Significance of the Roulette Wheel

The entire roulette set meanwhile, takes only two primary elements, that is, the wheel and the betting layout. Yes, you can do away with the table and play roulette with just these two crucial components. However, the game can never be possible without one or the other. In theory though, you can still play the game with just the wheel.

The wheel truly is the most important part of every roulette table. It serves no other purpose than deciding which bet should win – perhaps the most crucial function in the game. Roulette in fact, will never be without the wheel. After all, that’s where the game’s name, which is French for “little wheel” came from.

The Two Forms of the Wheel

Now the wheel comes in two variants, both classified merely for the amount of green zero slots present in them and nothing else. Usually, a casino would only feature one type of wheel and not both. This is because the number of zeros on the wheel dictates the house’s advantage. As such, the casinos’ choice of the wheel shows whether it cares for profits or attracting customers.

The first is the single zero roulette wheel which is also called the European roulette wheel. This wheel is often associated with European and French roulette, and is the most common of the two roulette wheels. As the name suggests, it features one zero slot in addition to the numbers 1-36. The single zero allows for better chances of winning with even-money or dozen bets.

The other roulette wheel is the double zero wheel. This is exclusive to the American version of the game, which is the prevalent variant in the US, South America, and a few other places. This wheel has two zero slots, namely 0 and 00, and is slightly larger than its single zero counterpart. Naturally, the presence of two zeros made winning a little harder and the house edge significantly higher, and as a result, most casinos favor the single zero wheel instead of this.

As you can see, the wheel dictates not only the winner, but also the odds and house advantage there is in a roulette game. A wise gambler therefore should take whatever the casino’s choice in roulette wheels to account if he or she is scouting for the best casino to play the game in.

An Orientation of the Roulette Wheel for Beginners

Roulette is a popular game of chance that people will often think of at the very mention of the word “casino”. It is perhaps the most played and well-understood of all games that can be played in gambling establishments. Roulette owes this to its relatively simple game set up and mechanics as well as its high winning odds – characteristics that have kept roulette in the hearts of many despite the passage of time.

Roulette Table and Wheel Explained

The casino game is played on a table with a board and a wheel. The board is where players place their bets, represented by chips that are colored differently for identification purposes. This part of the roulette table is composed of colored spaces for two types of betting areas: the inside and outside bets. For those new to the game, inside bets are stakes placed on one or more specific number, i. e. single zero (0), double zero (00) and 1-36. Meanwhile, outside bets are bets placed on either colors (black and red), number types (odd and even) and certain number ranges on the board, namely 1-18, 19-36, dozens and columns.

The second main component of the roulette table is the wheel. Now the roulette wheel is the centrepiece of every roulette table. It is the core of every roulette game, and is the game’s very namesake – roulette is a French word that literally means “little wheel”. The wheel’s primary design features include 37 or 38 colored numbers that represent the bets on the roulette board; pockets next to the numbers the ball is meant to stop on; and a track near the rim on which the ball is rolled.

2 Main Variants of the Casino Game’s Wheel

Several variations of the wheel have sprung up over the years, the most well-known of which are the European and American versions. We will discuss in the following paragraphs these two main varieties.

Single Zero Wheel in European Roulette

The wheel used in European roulette is perhaps the most commonly used version worldwide, and can be considered the “default” design. This version of the roulette wheel has 37 numbers: one green single zero (0), and sixteen red and sixteen black numbers, arranged in alternating colors and randomly numbered 1-36. It is worth noting that the presence of only one zero ensures a house edge of 2.7%, which is much lower than its American counterpart.

The single zero wheel is considered the original version, though early descriptions of the wheel mentions two zero slots instead of one, a configuration popular to casinos for its higher house edge which is directly proportional to the gambling establishment’s profit. It was not until the latter half of the 19th century that the single zero wheel gained tremendous popularity and became the norm in casinos all over the world except those in the United States.

Double Zero Wheel in American Roulette

As every gambler probably knows, American roulette is notorious for its high house advantage of 5.26%. This is reflected in its roulette wheel, where double zero (00) slot still exists when it was already scratched off the roulette wheels outside the New World. That being said, the American roulette wheel, unlike its European version, has 38 numbers: two green slots for 0 and 00, and the same count of red and black numbers as in its Old World counterpart. The numbers are arranged in alternating colors and in an orderly fashion, that is, a number is arranged opposite of the next number in the sequence, and is followed by the number after its pair.

The double zero wheel that’s used in American roulette was once the standard of all casinos. In the 19th century, while the single zero wheel is favoured in European casinos and elsewhere, the double zero design remained in American gambling establishments, where it has been kept alive up to this day.

As if its high house edge is not enough, early American roulette added the American Eagle slot into the double zero wheel, thus increasing the house advantage to 7.69%. This so-called Eagle wheel’s popularity soon vanished and only a few remain today, with well-maintained antique ones netting five figures of cash in auctions.

It is the wheel that makes roulette. Indeed, it is this humble device that made the game enjoyable for many generations of casino players. The roulette wheel therefore deserves no less than becoming not only the ultimate representation of roulette, but also among the universal symbols of casinos and the gambling industry itself.
