Introduction
Many roulette players wait for some sort of ‘trigger' before implementing a betting progression strategy. One example could be waiting for black to win 3 times in a row. From here, the player would double the bet until they win. This will not help the player win. 5 Number Bet – Bets on 0,00,1,2,3 at the same time. Only available on American roulette. This is also the worst bet in the entire game because of the unfair payout – avoid it. Double Street (Line Bet) – This is the same as the Street bet except it covers two Streets at the same time rather than one.
- Each double street is numbered so to avoid confusion: 1 - 6 is 1 7 - 12 is 2 13 -18 is 3 19 - 24 is 4 25 - 30 is 5 31 - 36 is 6 So if 23 spins then that is Double street 4 So you bet DS 4 next spin. 35 spins (DS 6) Bet DS 6 + 4 12 spins (DS 2) Bet DS 6 + 4 + 2 24 Win Hope this makes sense. Basically its backing the last spun double streets.
- Double Street is just what it sounds like – you bet on two rows of numbers, a total of 6 numbers. The payout is 5:1, and the odds are 16.22% and 15.79% for European and American Roulette, respectively. Basket, or a five number bet, is available only in American roulette, and allows players to bet on the zero, double zero, 1, 2, and 3.
- 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.

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

Strategy
Roulette Strategy Double Bet
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 is a fun game to play, whether it's by yourself online or live with other players. But it can be sort of tricky to learn at first with all the different types of bets you can make – especially if you play live.
The challenge with playing live is that many of your bets are made as the wheel is spinning. If you don't know what bets you can make, how to make them, or how they work, you might slow the game down. Then the other players will know you're a beginner. Some people might find that embarrassing.
So it's a good idea to have a solid understanding of the types of roulette bets you can make before you hit the casino. Even if you're playing online, you'll still want to know what you're doing – what you're betting on and why you're betting it.
It also helps to know the odds, payouts, and house edge of each roulette bet. That way you can make an educated choice about how much risk to take and know how much money you stand to win/lose.
