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.

Rules

General Rules

An ordinary single- or double-zero wheel is used.
Most of the layout is the same as conventional roulette.
Two balls are used.
Both balls must be successful for 'outside' bets to win. For example, for a bet on Red win, both balls must land in a red number.
Either ball must be successful for 'inside' bets to win. The player will win twice as much if both balls result in a successful outcome.
For the 'Double Ball Jackpot' bet to win, both balls must land in the selected number.
A remote-controlled button is given to a player to activate the air gun shooting the balls.

Available Bets

Red, Black, Odd, Even, 1 to 18, 19 to 36 — Pays 3 to 1 if both balls land in the chosen 18 numbers.
1st 12, 2nd 12, 3rd 12 — Pays 8 to 1 if both balls land in the chosen 12 numbers.
1 red, 1 black — Pays 1 to 1 if one ball lands in a red number and the other black.
One Number — Pays 17 to 1 if either ball lands in the chosen number, and 34 to 1 if both do.

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.

Strategy

As with any game of pure luck, all you can do for yourself is to make the bets with the lowest house edge. In this case it is the single-number inside bet, with a house edge of 2.78%. If that is too volatile for you, the double-number inside bet is not much higher at 2.99%

Roulette offers a bewildering number of betting options, but the bets are actually straightforward enough. In order to make sure you get the correct payout, you’ll want to make sure that you put your chips in exactly the right place on the table. Missing a payout because your chip isn’t in the right spot is a drag.

Roulette payouts are an important part of roulette strategy. They work like this. The odds are stated in the form of x to 1, which means you’ll win x dollars for every dollar you’ve bet. For example, the single number bet offers a payout of 35 to 1. If you win, you’ll get your dollar back plus the $35 for the win.

Payouts on the Outside Bets

On the edge of the table are a series of bets which are “outside” the 38 numbers on the table. Each of these bets refers to a specific set of numbers or colors. If the ball lands on 0 or 00, you’ll lose on any of the outside bets.

The outside bets include:

Red or Black – This bet pays out even odds (1 to 1) if the ball lands on the color you chose.

Odd or Even – This bet pays out even odds (1 to 1) if the ball lands on odd or even, depending on which you chose.

Low or High – This bet pays out even money (1 to 1) if the ball lands on 1-18 if you bet low, or if the ball lands on 19-36 if you bet high.

Columns – The numbers on the layout are organized into three columns of twelve numbers each. A “columns” bet wins if the ball lands on one of the numbers in the column you chose. This bet pays out 2 to 1 when you win.

Dozens – There are 36 numbers on the table, so you can bet on the first dozen (1-12), the second dozen (13-24), or the third dozen (25-36). This bet also pays out 2 to 1.

Payouts on the Inside Bets

You can also bet on specific numbers and sets of numbers on the inside of the layout. These bets win less often, but they pay out more when you do win. The house edge on the inside bets is the same as the house edge on the outside bets.

The inside bets for roulette include:

Straight-up – This is a bet on a single number. It pays off at 35 to 1.

Split bet – This is a bet on any two adjacent numbers. You place the chip on the line between the two numbers in order to make this wager. This bet pays out at 17 to 1.

Street bet – This bet covers three numbers. You place your bet on the line outside of the three numbers in the row where you want to win. This bet pays out at 11 to 1.

Corner bet – Some people call this a square bet or a quarter bet. It’s a bet on a corner that makes a square, and it’s a bet on four numbers. A win on this type of bet pays out at 8 to 1.

Five-number bet – You can only make one five-number bet, and it’s the only inside bet that offers different odds from all the others. The problem is that it has a higher house edge, making it the worst bet on the table. This bet is on the numbers 0, 00, 1, 2, and 3, and you place the chip on the outside corner line between the 1 and the 0. This bet pays out 6 to 1, but only masochists place this bet.

Six-number bet – Some people call this a line bet. It covers two adjoining rows of numbers. It pays out at 5 to 1.

How Roulette Payouts Give the Casino an Edge

These payouts all have one thing in common—they pay out less than the true odds of hitting a win. That’s why the casino enjoys a house edge of 5.26% on roulette. Your odds of winning are always less than the payout amounts.

For example, the odds of winning a straight-up bet are 37 to 1. There are 37 numbers on the wheel that lose, and 1 bet on the wheel that will win. But the bet only pays out 35 to 1, not 37 to 1, so the house wins more often than it loses.

A split bet offers you odds of winning of 18 to 1, but it pays off at 17 to 1.

I could list all of them, but you get the idea by now. The casino has an unassailable mathematical advantage on every bet. No betting system or strategy can overcome this advantage.

Of course, in the short run, anything can (and often will) happen. This is called “standard deviation”, and it explains why some people walk away from the roulette table as winners. The mathematically true results only come around the closer you get to an infinite number of spins.
