The game of roulette is one of the most renowned casino games, where the spinning ball and wheel excite players all over the globe. But not every roulette wheel is the same. Although most casinos operate the double-zero wheel (00), there are still those that use the single-zero wheel (0). Why?
In this article, we’ll explore why single-zero roulette wheels remain popular, how they affect the odds, and why casinos like National Casino still rely on them despite the rise of more modern variations.
The Basics
First, it is important to understand the key differences between the two main types of roulette:
European (Single Zero) Roulette
- Features numbers 1 through 36, plus a single zero (0).
- House edge: 2.70%.
- Lower risk for players compared to double zero wheels.
American (Double Zero) Roulette
- Features numbers 1 through 36, plus single zero (0) and double zero (00).
- House edge: 5.26%, which is almost double that of the European.
- Higher profits for the hall due to worse player odds.
On a superficial level, it appears that casinos would like the double zero option all the time since it will give them a greater advantage. But why do some continue to use the single zero version?
The Hidden Advantage
1. Attracting High Rollers
Single zero roulette is often found in high-end casinos and VIP rooms. Why? Because experienced participants know the odds are better, as a 2.70% house edge is much more appealing than 5.26%, especially for those playing with large sums.
This lures in high-stakes gamblers who prefer better odds, as they may put more money down over time, making up for the slightly lower house edge.
2. Psychological Appeal: Fairness and Tradition
Most also think that single-zero roulette is fairer in terms of giving them a good chance of winning. Casinos, which provide this game, have a reputation for being player-friendly. This can gain them loyal customers.
In addition, the single-zero roulette is historically significant. It is the original European variant, and some casinos use it to create the impression of classiness and tradition.
How It Affects Strategies
Many strategies, like the Fibonacci system, work slightly better on single zero wheels because of the lower house edge. Here’s why:
Lower House Edge Means Fewer Losses Over Time
- On a double zero wheel, a 5.26% house edge means players lose $5.26 per $100 bet on average.
- On a single zero wheel, that drops to $2.70 per $100 bet.
Why Don’t All Casinos Use Them?
If single zero wheels are so great, why don’t all casinos use them? The answer comes down to the target audience and profit margins:
Most casual gamblers don’t pay attention to house edges. They just want to have fun. Since double zero wheels bring in nearly twice the profit, many casinos (especially in the U.S.) prefer them.
As the odds are better, playing halls often set higher minimum bets on single zero tables. This ensures they still make good profits, even with the lower house edge. Not all people can afford these tables, so double zero wheels remain the default in many places.
