The Best Roulette Game in Las Vegas – Why and Where to Play Single Zero Roulette

We have all seen a roulette wheel. Some of us have even played it in a casino. While all roulette games look the same at first glance, small variations in the winning payouts and even the wheel itself can lead to sizable differences in the expected outcome for both the player and the casino. In this article, we will show you the three main roulette games available in American casinos. We will take a deeper look at the underlying mathematics of each game to determine which variant of roulette is best, and why. Finally, we will help you track down the best roulette game in Las Vegas!

If a roulette wheel had only 36 pockets (the little slots on the side of the wheel into which the ball eventually drops) the game would be truly fair. The 1-in-36 (2.78%) chance a player would have to win 35-to-1 would exactly offset the 35-in-36 (97.22%) chance he or she would have to lose.

Casinos, of course, are in the business to make a profit. The money to buy the liquor they serve for free, to build and maintain the dancing fountains, and to pay the wages of everyone from the bellhop to the pit boss to the celebrity headliner has to come from somewhere. A lot of it comes from the house edge , which is the mathematical advantage over the player that is built into every game the casino offers.

In most roulette games offered in American casinos, that advantage is provided by the green 0 and 00 pockets both on the wheel and at the top of the layout. Instead of 36 pockets, a typical American roulette wheel actually has 38: the numbers 1 through 36, 0, and 00. The presence of the 00 pocket leads to American roulette sometimes being called "double-zero roulette." In double-zero roulette, the player now has only 1 chance in 38 (2.63%) of winning 35-to-1; the probability of losing has increased to 37 out of 38 (97.37%) Even the most math-averse reader can see that this setup is disadvantageous to the gambler. More specifically, the 2 extra pockets give the casino a house edge of 5.26%. Over the very long run, for every $ 10,000 the casino collects in losing wagers, it pays back only $ 9474 in winnings. It should be pointed out that all bets available on double-zero roulette – except one – have the same house edge. The comparative payouts and probabilities for straights, streets, corners, and splits, as well as the lower-paying bets on the outside of the layout, are all structured to have this same house edge of 5.26%. The one exception is the "basket," which is a wager on 0, 00, 1, 2, and 3. This wager pays 6-to-1 and has a house edge of 7.89%.

Serious roulette players who want to minimize the house edge should track down and play single-zero roulette. In single-zero roulette, the green 00 pocket is missing; the wheel has only 37 pockets. This is as close to fair as the wheel can get. The player has a 1-in-37 chance (2.70%) of winning 35-to-1, and a 36-in-37 chance (97.30%) of losing. This is only a 7 one-hundredths of a percent increased probability of winning on any particular number, but it has a significant effect on the house edge. Single-zero roulette has a house edge of only 2.70%, compared to 5.26% for double-zero roulette. That works out to an extra $ 256 in winnings per $ 10,000 collected.

Some single-zero roulette games offer another variation on their payouts. If a player wagers on one of the even-money outside bets on the layout (even, odd, red, black, 1-to-18, or 19-to-36), and the ball lands in the 0 pocket, the casino collects only half of your losing wager. For example, if you wager $ 10 on black, and the ball lands on 0, the house only takes $ 5 of your wager.

In an even rarer variation, the dealer may give you the choice of either losing only half your bet, or putting your bet "in prison." Here's what happens when you go to roulette jail:

1) The dealer puts a marker over your bet (the full $ 10 bet from before) that says en prison . You can neither add nor take away from your wager for the next spin.

2) The dealer spins the roulette wheel again for the next round.

When the ball finally comes to rest, one of two things will happen. Again, let us assume we have a $ 10 en prison bet on black.

1) The ball lands on black. You do not win anything, but it is like a jailbreak for your wager. The en prison marker is removed and you are free to do what you wish with your $ 10. Effectively, you get your money back.

2) The ball lands anywhere else (red or 0). You lose.

The en prison or "half back on even money" option cuts the house edge on these bets to a meager 1.35%. All of the other bets on the layout remain at the usual single-zero house edge of 2.70%. As far as I know, no casino offers this option on double-zero roulette. If one did, the house edge on these even-money wagers would be 2.63%.

By this point, we have shown that single-zero roulette is the more advantageous variation to play. It is the standard roulette game across Europe and Australia; a double-zero roulette game in Monte Carlo would be practically unheard of. You will also find single-zero roulette in many casinos throughout the Caribbean and the Pacific Rim.

Single-zero roulette is significantly harder to find in the United States, but it is out there. Many of the larger, higher-end casinos on the Las Vegas Strip offer it in their high-limit gaming sections only. A few of the more "European-themed" hotels are rumored to even offer the en-prison option.

If you lack either the bankroll or the stomach to wager $ 25, $ 50, or even $ 100 per spin, head to Las Vegas and visit Caesar's Palace, Mandalay Bay (on weekends only), The Mirage, Monte Carlo (Friday and Saturday nights only) , Nevada Palace, Stratosphere, and The Venetian.

Note that at Caesar's, The Venetian, and Mandalay Bay, while their regular roulette tables may not technically be "high-limit" tables by their standards, they may still have a $ 15 minimum bet.

Several Las Vegas casinos reportedly offer single-zero roulette in their high-limit areas only. Other casinos not listed here just might offer it if a known high-roller requests it. Las Vegas casinos that limit their single-zero roulette to their high-limit tables include Bellagio, Golden Nugget (at high roller request only), Las Vegas Hilton, Luxor (weekends only), MGM Grand, Paris (at high roller request only) , Rio, and Wynn Las Vegas.

A few of these high-limit tables even offer the favorable en prison option. Gamblers have reported playing en prison at the high-limit tables of Bellagio, Mandalay Bay, MGM Grand, The Mirage, Rio, and Wynn Las Vegas.

Several casinos in Atlantic City offer single-zero roulette in their high-limit areas only. I have heard of none that offer en prison . You can play high-stakes single-zero roulette at Tropicana, Showboat, Harrah's, Caesar's, Trump Marina, and Trump Taj Mahal.

These lists of casinos will no doubt change as time goes on. Some games increase in popularity while other tables have no one but a lonely dealer at them at 10 o'clock on a Friday night. In the time between this article was written and is now being read, some casinos may have expanded their single-zero roulette games or gotten rid of them entirely. An attempt is being made to keep track of all active single-zero roulette games in the United States at the Single Zero Roulette Squidoo Lens at [http://www.squidoo.com/singlezeroroulette/].

We have shown that single-zero roulette offers substantially better odds for the gambler than does the more common double-zero American game. The gambler will ultimately lose money over the very long run at any roulette game. Because of the lower house edge, however, the gambler has a better chance of winning money in the short run at the single-zero tables, particularly if the game offers the en prison option. Any roulette enthusiasts who want to maximize their wins – or even just minimize their losses – would do well to find and play the more advantageous, single-zero roulette game.
