For any complete novices out there, a roulette wheel is made up of 37 numbered pockets (or 38 if you are playing American roulette – and as an initial piece of advice you shouldn’t, as it decreases your chances of winning!). Half of these numbers are coloured red and half are black with the ‘0’ pocket green. A small ball is introduced when the wheel is spinning and players must predict where the ball will land.
You don’t have to be a mathematical genius to excel at roulette but it makes sense to memorise the sort of odds you’ll receive for different bets. Although it’s unlikely that a croupier will make a mistake and underpay you, if you don’t know the odds of the bet you’ve placed, how are you supposed to correct them? Even if you’re only playing online roulette, it still pays to familiarise yourself with the odds you’ll receive for betting on different sections of the table. That way you’ll be able to calculate the possible return and can adjust your strategy accordingly. If you don’t know the difference between zero and double-zero roulette for instance, you don’t know how to calculate your odds and you’re just guessing. Don’t guess – calculate. We’ll show you how.

The “house edge” is what enables the casino to profit. An example is the European wheel has 37 pockets, but a 35-1 payout on single numbers. So if you win 1 in 37 as you’d expect with random bet selection, you’d be paid 35 units plus your original bet, leaving you with 36 units. But if roulette’s payouts were fair, you’d be left with 37 units after the 37 spins. Simply the house edge is unfair payouts. And it affects every bet and every roulette strategy. Even when you win, you are still getting paid unfairly.
My goal with this roulette strategy is to keep you away from the devastating loss that the Martingale ultimately entails. Plenty of times on the two spins that you sit out there will be a winning spin – had you bet it. More times there won’t. Remember the casino has that edge on all of those even-money wagers. That fact should always be front and center in your mind. Never think you are playing an even game even on bets called “even-money” bets.  
 One of the most popular Roulette strategies, the Martingale system, is a fairly easy one to learn and replicate. The system itself is named after London casino owner John Henry Martindale, who encouraged players to double their bets after a loss. It works like this: simply place an even money bet, and if you lose, double your bet the next time round. If you win, place the exact same original bet on the next spin. Using this betting strategy will help you keep control of your bankroll, and while you may not win millions, you’ll be able to walk away with a healthy account balance – which most players would call a win in itself.
I am a roulette player. Neither an “editor” nor a “mathematician”. The difference is that I put my money where my mouth is. Most roulette sites are written by editors who have never placed a bet. They recycle knowledge and recite Wikipedia. And they are paid to write. I have paid dearly for every single word I write. I have invested money, time, aspirations and grey matter in roulette.
I read an interview that the founder did wherein she said Broadway Roulette prides itself on being all about discovery, i.e funneling people to shows that are new or struggling that the average consumer might not visit on their own. However, someone looking for cheap/random/last-minute Broadway tickets is more likely to see one of those shows due to their low box office cost and sheer availability, so it doesn't seem worthwhile to utilize Broadway Roulette as a service if that's what you're going for. Most of the fun of Broadway Roulette is the gamble --- the chance that you might get a hot show for a low cost --- and yet the service is geared towards those last-minute impulse purchases that a consumer could easily achieve for the same price at a random show's box office if they were so inclined, especially since you don't find out what show you're going to be seeing until that same day.

Cross-reference roulette system: Cross referencing is a type of analysis where all available data is considered, and used to detect usable patterns. What makes it special is the data cross-referenced to ensure accuracy. This enables the player to better find hidden patterns in spins, and in less time. Also it enables players to quickly adjust when conditions at the wheel change. The method of cross referencing is not exclusive to roulette, and can be applied to other casino games. But this particular roulette system is combined with other predictive methods that are exclusive to roulette.

As an off-topic point, I was also put-off by a post I read on their website blog about what a theatre goer should and should not wear to the theatre. While the main point of the article was not to wear denim cutoffs to the show, they also bizarrely and randomly listed a number of other things patrons "shouldn't" wear, including vintage jeans, old logo t-shirts (something that, if the writer was actually as trendy as she smugly purported to be, she might know are back in style and can be dressed up quite nicely under a cool jacket or layered necklace) and leggings. For a brand that capitalizes wildly on "making Broadway accessible to everyone," it came off grossly classist and policing of what I can only assume is its target demographic --- young people on a budget.

It's important to understand that the outcome of the roulette wheel is truly random.  If Black has come up for the last 10 spins in a row, the next spin is not more likely to be Red.  Black and Red are still equally likely. There's an old saying, "The wheel has no memory."  That means it doesn't know what it spun before, and even if it did, the wheel can't select what number comes up out of its own volition.  There's more on this in my article Debunking the Gambler's Fallacy.

By the way, I want to take a moment to point out that this tidbit above about even money bets in Atlantic City is just one of the many fabulous bonuses you learn about for free on this site, which you might not find out about from books that cost actual money.  When I was learning about gambling, the first thing I did was to buy and read the book The Complete Idiot's Guide to Gambling Like a Pro. But in 332 pages they didn't see fit to mention the low edge in Atlantic City, so I didn't know about it.  I found out about it when an Atlantic City dealer took only one of my two chips on a losing bet and I had to ask why.
Here's another example: Since there are 38 slots on the wheel, we expect any given number to hit 1 out of 38 spins on average.  Now let's say you've been playing Roulette for a few hours, betting on Red every time, and you've been keeping track of what numbers have hit.  There have been 152 spins (4 x 38), and so we expect that each number should have come up 4 times on average.  You note, with some surprise, that #14 hasn't come up at all.  Does this mean that #14 is "due" and that you should bet on #14?  No.  Number 14 is not "due", no number is ever "due".  The wheel has no memory.

My goal with this roulette strategy is to keep you away from the devastating loss that the Martingale ultimately entails. Plenty of times on the two spins that you sit out there will be a winning spin – had you bet it. More times there won’t. Remember the casino has that edge on all of those even-money wagers. That fact should always be front and center in your mind. Never think you are playing an even game even on bets called “even-money” bets.  
Roulette games have minimum bets, which will be posted on a placard at the table.  Minimum bets work differently for inside bets (specific numbers) and outside bets (everything else).  For outside bets, any bet you make has to be at least the table minimum.  Inside bets can usually be as small as you like, as long as the total of all your inside bets is the table minimum.  For example, with a table minimum of $5, you could put $5 on #14, or $1 each on #14, #27, #8/9, #28/29/30, and #19/20/22/23.  Remember that you can bet inside or outside if you like; there's no requirement to bet both on a given spin.
You can’t determine which number that ball will land on but you can determine the amount you’ll win when your bet comes in. The best players have a roulette strategy, which can range from the extremely simple to the surprisingly complex. Approaching roulette with a gameplan in mind makes sense as it’s a smart way to make the most of your money. Whether you choose to play conservatively or aggressively will depend on a number of factors including the level of profit you’re seeking and the level of risk you’re willing to expose yourself to. We’ve put together a guide to some of the best roulette playing strategies available.
