American Wheel Sequence. The American version of roulette is known for having the highest casino advantage of them all, peaking at 5.26%. This is all because of the extra green slot, labelled ‘double zero’. In American roulette the numbered wheel features an additional '00' square as well as the standard '0' found in French and European roulette. The inclusion of this '00' isn't a positive for.

Double Zero Roulette

Quick Links

Roulette has existed in France since the 17^th century, however…

The original wheel was different to a roulette wheel you’d see today. In the fact, there were no zero slots. The zeros were introduced when the game made the move into the casinos in order to give the casino a house edge at the same time lowering players’ odds of winning.

Casino owners in the US decided to introduce a second zero, commonly known as double zero, to increase revenue for the house which gave the birth to double zero roulette or American roulette as it is also referred by many roulette players around the world. Below, you will find all the information necessary to understand double 0 roulette.

Double Zero Roulette – Explained

There are 38 slots on this wheel, with two zeros alongside every number from 1 to 36

The zeros are numbered 0 and 00 so you’ll be able to differentiate between the two. Both zeros are colored green, and the other numbers will alternate between being black and red. It might seem that the numbering on the double 0 roulette wheel is somewhat random; however, the distribution is arranged so that the sum of a group of numbers on one part of the wheel will be similar to another area of the wheel of the same size.

Double Zero Roulette Wheel Layout

The double zero roulette wheel layout is almost the same as in other roulette game variations. The main difference is the presence of additional slot with double zero in the wheel’s layout itself. On the other hand, you will find that both European and French roulette have just single zero so there is no difference in the wheel layout between these two roulette game variations.

Double Zero Roulette Strategy – Types Of Bets

You’ll find a large number of betting options when playing double zero roulette. When playing roulette, you might notice that that betting area is divided into two sections, with the individual numbers on the ‘inside’ and the groups of numbers on the ‘outside’. Your double 0 roulette strategy will depend on the type of bet you will choose to place on the roulette table.

We list the most common inside and outside bets you will find at a double zero roulette table:

Roulette Bet Types – Inside Bets

• Straight – You’ll place your chips on a single number
• Split – A split is a bet on two adjoining numbers
• Street – This is a bet on three numbers together on a horizontal line

Roulette Bet Types – Outside Bets

• Red or Black – You place your chips on whether the ball will land in either red or black
• Odd or Even – Another even money bet – if the ball lands in either zero, you’ll lose your bet
• 1/18 or 19/36 – You’ll be betting on the lower or the higher group of numbers

Roulette With Double Zero Strategy – Rules Variations

You’ll find a variation of the ‘La Partage’ rule available when playing roulette with double zero

This is particularly the case when playing in Atlantic City and on select tables in Las Vegas. This rule comes into effect when the ball lands in either of the zero slots and leads to players receiving half of their stake back. This changes the house edge from 5.26% down to 2.63% which actually gives the house a lower edge than the European game. This is the one instance where we would recommend double zero roulette over single zero.

Important: If given the options, always play European roulette (single zero roulette) unless you can take the advantage of the ‘la partage’ rule while playing American roulette.

House Edge In Roulette With Double Zero

The casino has a 5.26% edge when playing roulette with double zero.

This doesn’t fare favorably in comparison to other versions of the game, European roulette as an example having an edge of just 2.70% in the casino’s favor. Therefore, we would recommend playing roulette at a European wheel or French wheel if given the choice of among the games.

Introduction

Double Ball Roulette plays like regular roulette, except with two balls. I first saw the game at the 2013 Global Gaming Expo and later at the Tropicana in Las Vegas on February 18, 2014. The Tropicana uses a double-zero wheel.

Later, in November, 2016, I noticed it at an Internet casino using Felt software. Felt uses a single-zero wheel.

You might wonder about how they keep the balls from hitting each other in a physical game. The game uses compressed air to shoot the two balls out of a tube almost simultaneously. They travel at the same speed so the second ball always trails the first one.

You might also wonder if the probability of the two balls landing in the same number is about the expected 1/38, assuming they the two outcomes were completely independent. At least I wondered this and annoyed the game maker with physics questions at the gaming show for much too long about it. He assured me that an independent lab did tens of thousands of spins and the probability of the two balls landing the same number is about the expected 1/38, assuming they two outcomes were completely independent.

The betting layout is mostly the same as standard roulette. With the inside bets, the player has two chances to win, but the pays are less. On the outside bets, both balls must win, but the pays are more. In addition the player may bet that both balls will land in any one number.

The next table shows my analysis of all 6-number (double street) bets.

All 6-Number Inside Bets — Double-Zero Wheel

Strategy

My advice in any game is to go for the bets with the highest expected return. In the case of a double-zero wheel, the best bet is the inside bets on one single number, at a house edge of 5.33%. The two- and three-number bets are not much worse at 5.54% and 5.89% respectively.

I would be remiss in my duties if I didn't say that the house edge in standard double-zero roulette is lower at 5.26%. However, this is only 0.07% lower than the single-number inside bet in Double Ball Roulette.
