Winning at roulette doesn’t take a magic formula or a secret system. It’s purely a game of luck. So if you’re looking for a secret strategy or surefire way to win, you’ll probably be disappointed by the information on this page. On the other hand, if you’re interested in learning the real odds of winning and what you need to do in order to be a winner, you’ll be thrilled by the info on this page.
The Odds of Winning at Roulette
An America roulette wheel has 38 numbers on it—the numbers 1-36 (inclusive), a 0, and a 00. Calculating the odds of winning a bet on any single number is simplicity itself—you have one way to win out of 38 possible outcomes, which makes the odds of winning 37 to 1. This bet pays out at 35 to 1 odds.
Of course, the single number bet isn’t the only way to win at the roulette table. A plethora of betting options await the roulette player, in fact. These betting options have different odds of winning, but they also offer different payouts.
In roulette odds of winning are not truly impacted by your betting strategy, but your odds of winning money are. The difference is that you can win a spin and still lose money. Consider the following scenario. You put money $20 each on Red, Even, the first half. Would there be any difference in the ultimate statistical odds of surviving Russian Roulette if you were to re-spin the chamber before handing the gun to the next player (as opposed to one bullet, six trigger pulls or less, game over)? Think about a revolver with exactly two cylinders.
Another easy example of roulette odds are the even money bets. 18 of the numbers on the roulette wheel are red. 18 of them are black, and two of them, the 0 and the 00, are green. So if you bet on black (or red), then you have 18 ways to win and 20 ways to lose. Your odds of winning are slightly less than 50%. 18/38 is 47.36%. This bet pays out at even odds.
If you’re paying attention, you’ll notice that in both of these scenarios, your odds of winning are less than the payout odds. This is what gives the house an edge over the player. In the short run, anyone can walk away from the roulette table a winner. But in the long run, the house is always going to come out ahead.
So how do you become a winner at roulette?
The Maximum Boldness Strategy
Let’s assume that your goal is to just double your money. How do you maximize your chances of doing that?
The correct mathematical strategy is to make one bet of your entire bankroll, cross your fingers, and hope you get lucky. If you lose, you’re out of money, but if you win, then you’ve succeeded in your goal.
The maximum boldness strategy entails placing a single even money bet and hoping to get lucky. You’ll have a 47.36% chance of doubling your money.
Suppose, on the other hand, that you’re going to place two bets with half your bankroll. You’ll have to win both bets in order to double your money. What’s the likelihood of that happening?
That isn’t hard to calculate either. When you’re calculating the probability of two events happening, you multiple the probability of each event happening. So you would simply multiply 47.36% by 47.36%.
The result?
22.42%
Your chances of doubling your bankroll drop dramatically in that case, don’t they?
Suppose you divided your bankroll into four separate bets. Your chances of doubling your money would drop even further.
47.36% X 47.36% X 47.36% X 47.36% = 5.03%
So if your goal is to double your money, the best strategy is to place a single bet. The more bets you place on any negative expectation wager, the more likely the house edge is to catch up with you.
You might still walk away a winner in this situation, but it will be a smaller win. And you’ll be less likely to double your money.
What about Systems?
Roulette systems don’t work. Most of them involve increasing or decreasing your bet based on the outcome of your previous bet. The idea is that the odds of losing several bets in a row is smaller than the odds of losing a single bet, and vice versa.
The problem with this line of thinking is that you’re not placing a single wager on a series of bets. You’re placing multiple wagers on multiple events, and the odds of each event are independent of each other.
The house’s edge over the player doesn’t change based on the previous spin of the wheel. If you bet on black and lose, then the odds of black hitting on the next spin are still 47.36%. The probability doesn’t change because of what happened previously.
The most common of these bogus systems is the Martingale system, which requires you to double your bet every time you lose. The idea is that you’ll eventually win back your previous losses plus a single unit.
Here’s an example. Suppose you bet $5 on black and lose. On your next bet, you wager $10 on black. You lose again, so your next bet is $20. This time you win, so you’ve won back the $15 you lose on the first two bets, plus $5.
At first glance, this seems like a pretty good system. But it has two problems.
The first is that you’ll eventually hit a losing streak where your next bet will be too high for your bankroll. It only takes eight losing bets in a row to get to the point where you’ll need $1280 to place your next bet. (The progression looks like this: $5, $10, $20, $40, $80, $160, $320, $640, $1280.) And remember—you don’t just need $1280 for the last bet. You’ve already lost $1275 by this point in your betting progression.
If you do win this $1280 bet, you’ll only be up $5, which means you’re making a large wager for a very small return.
The other problem is that even if you do have a sufficient bankroll to cover this kind of progression, all casinos have maximum bets. If you’re playing at a $5 roulette table, the maximum bet is probably $500 or $1000. So you’ll be unable to continue your progression.
You might be thinking, how often will I have a losing streak of eight in a row, though?
That answer is not often, but it will happen often enough to make sure that you’re not a long term winner at roulette.
So How Do You Win at Roulette?
In the short run, the only way to win at roulette is to get lucky and walk away. In the long run, the only way to win at roulette is to get even luckier and quit while you’re ahead. The more you play a negative expectation gambling game, the more likely you are to become a net loser.
Best Odds Of Winning Roulette
Does this mean you shouldn’t play roulette?
That’s not our point at all. If you enjoy roulette, then play. Just don’t think you can make a living at it by using some mathematically bogus system or strategy. Earmark your roulette money as an entertainment expense. Then play as much as your bankroll allows until you’re no longer having fun.
What are the pros and cons of roulette versus the pros and cons of blackjack? How do these games differ, and how are they the same? Like all casino games, they have certain characteristics that hold true for every game you’ll play in a casino. But they also have significant differences, which I’ll analyze for you on this page.
Independent Events versus Deck Composition Strategies
The odds in roulette never change, no matter what happens on previous bets. If you bet on black, the odds are always either 18/38 or 18/37 that you’ll win. That’s because every spin of a roulette wheel is an independent event. Previous results don’t affect the odds on subsequent results.
This doesn’t mean that roulette gamblers understand this. Many of them stubbornly refuse to acknowledge the simple fact that it’s impossible to get an edge on roulette based on studying the results of previous spins. Martingale players take this to a systematic extreme by lowering and raising their wagers based on what happened on the last spin.
Imagine though a new roulette wheel, one in which certain numbers got filled in once they’d been hit. The odds would change with every spin of the wheel, right? For example, there are 18 black numbers, so the odds of winning a bet on black are 18/38. If you removed one of the black numbers after black hit, the odds of winning the same bet would be reduced to 17/38.

Best Bet Playing Roulette
It doesn’t take a math genius to understand how you could use this information to your advantage.
But that’s exactly what happens with a blackjack deck. Once a card is dealt, it’s gone, and the composition of the deck has changed. This is how card counters make money. They use a heuristic system to estimate how favorable the deck is to the player.
Some might have trouble getting their head around this idea, but it becomes simpler if you think of it this way. You get paid out 3 to 2 if you hit a natural “21” right? All other bets pay out at even money, so getting a natural blackjack is where a blackjack player makes his money.
But what are your odds of being dealt a blackjack if all four of the aces in the deck have already been dealt? They become 0, right? If the deck has 0 aces in it, and you need an ace and a face or ten to get the 3 to 2 payout, then the house edge increases considerably.
The same holds true for the tens, but there are more of them in a deck. And the reverse of this is true. As the lower cards are dealt, the ratio of tens and aces becomes more favorable. So the card counter raises his bet sizes to take advantage of the higher chance of getting a bigger payout.
Strategy versus Pure Chance
Another aspect of blackjack that’s different from roulette is the ability for the player to affect the house edge by making smart decisions. (The house edge is the percentage of each wager that the casino expects to win over the long run.)
In roulette, the house edge is fixed, regardless of what decisions you make. On an American wheel, you face a house edge of 5.26%. On a European wheel, you face a house edge of 2.70%. No decisions that you make can change this number.
On the other hand, there are multiple decision points in a blackjack hand. You could increase the house edge to 100% by hitting every hand until you bust, for example. (Most players are smarter than that, though.)
Smart blackjack players use something called “basic strategy” to make their decisions. Basic strategy provides the mathematically best play in every situation that might come up. It’s generally easy to memorize.

The difference between using basic strategy and just playing your hunches is significant. Game conditions vary, but generally speaking, if you use correct basic strategy, you can reduce the house edge to between 0.5% and 1%. Players who don’t know basic strategy face a house edge of 4% to 5%.
If you like making decisions that affect your outcome, and you want to play a game where you can get edge by an advantage maneuver like counting cards, skip the roulette table. Play blackjack instead.
On the other hand, if that sounds like too much trouble, roulette can be a lot of fun. It’s not a sucker bet, no matter what anyone tells you–unless you buy into some loony roulette system or superstition.
Wagers per Hour
Another difference that has a practical effect on a player is how many wagers per hour happen at the table in the two games. You can estimate how much money you’ll expect to lose per hour if you multiply the size of your wager by the house edge and multiplying that by the number of wagers you make per hour.
Roulette is a relatively leisurely game. If you’re playing at a table with five other players, you’re only going to be seeing 35 spins per hour. If you only place a single wager per spin, you can easily estimate your average hourly loss.
Suppose you’re betting $5 a spin. The house edge is 5.26%. So you can expect to lose about 26.3 cents per spin. You can expect to lose a little over $9 per hour at that rate.
Of course, with fewer players at the roulette table, you can expect to see more wagers per hour. If it’s just you and the dealer, for example, you can expect to see 100 or so spins per hour, which will triple your expected hourly loss.
Blackjack is a faster-paced game. If you’re playing blackjack at a table with 5 other players, you can expect to see 60 hands per hour. If you’re playing with perfect basic strategy (1% house edge) at $5 per hand, you can expect to lose a nickel per hand. That’s just $3 per hour. Even though you’re putting almost twice the money into action per hour, your entertainment is costing you even less.
Does that make blackjack better than roulette? That depends on your personality. Do you like a leisurely, elegant game? Do you prefer not to have to think too much when gambling? Then roulette is better than roulette—for you.
On the other hand, if you like card games and enjoy the challenge of making correct decisions, blackjack is more likely to be suited to your personality.
The pros and cons of each game are all based on what you prefer as a gambler.
