I’m fascinated by a certain mindset that exists among many casino players. This mindset relates to the fact that many casino players play games unaware of the house odds of those games , or if they do know the odds, have no idea what those odds mean in terms of money (won or lost). They have no idea what these roulette table odds actually are or how they relate to roulette game probabilities.



First, let me give you a simple example: What is the basic house edge in roulette (yes, in both the American version of roulette with the double zero wheel and the European version of roulette with the one zero wheel). And how does this fundamental advantage translate into the odds of winning at roulette?

Okay, the basic house edge on American double zero wheels is 5.26 percent and on European one zero wheels is 2.70 percent. In terms of money, this means that an American double zero roulette player loses 5.26 units for every 100 units bet, while the European one zero player loses 2.7 units per 100 units.

Well, the above information isn’t amazing and it’s easy to remember, but here’s the big question: how do these odds translate into the odds of playing roulette, and how do those odds compare to the odds of winning at roulette for both games see?



Yes, this is where many casino and internet online casino players crash – or (however awful that sounds) show little interest in an answer.

Let’s take the American double zero wheel first. The wheel has 38 numbered slots; Numbers from 1 to 36 plus a 0 and a 00. So let’s say you bet on 17, which is said to be James Bond’s favorite number and also the most bet number in the game.

With 38 totals, a bet on 17 is a bet on any number out of 38. There’s a 1 in 38 chance. So you’re betting on it, and 17 is an out of 38 chance. That one out of 38 number isn’t the odds of the bet winning.



You have one chance to win at roulette and 37 ways to lose the bet. The odds against you are 37 to one.

So the probability is one in the sum of the existing numbers (one in 38 for American double zero roulette); but the probability depends on how often you win (once) and how often you expect to lose (37 times).

How is this translated into money? Simply put, realize that a winner’s gain is not a 37 to 1 chance at roulette, as would be the case in a “fair” game, but 35 to 1. The casino cuts two units (the casino could not make money paying for “fair” odds and that would end the lives of casinos around the world, something we don’t want). Divide 2 by 38, then multiply by 100 and, as if by magic, the house edge is 5.26 percent (or 5.2631578 percent to be more precise).

Conclusion: The odds of winning at roulette do not match the actual payouts.



The same applies to the European one-zero wheel. On this wheel we have 37 numbers, one through 36 and a single 0. The probability of hitting is one in 37. The odds of winning at roulette are therefore 36 to one.

Unfortunately, the European one-zero wheels also pay out for a win at 35 to one, which is a cut of one unit. The true odds are 36 to one; the payout is 35 to one.

Now dividing that by 37 and then multiplying by 100, we get the house edge for the European one-zero wheels of 2.70 percent (or 2.7027027 percent, to be precise).



We need to take a closer look at another factor when we talk about roulette probabilities and odds. The fact that the odds of winning on American double zero wheels are 37 to one and 36 to one on European one zero wheels does not mean that there will be a winner on every 38 or 37 spins. Players wish it were, but it isn’t.

The odds of winning in roulette are more precisely that, odds on a mathematically based number over the long run. In the short term, the game of roulette (or any casino game ) can be totally insane. You can make many winners or few or no winners in dozens of dozens of choices. You may find yourself in the midst of a terrific defeat, or cheering like a man gone mad and stumbling around the casino like a god who has met the lucky fairy with a wild winning streak. Who knows that?



In the real world, as time inexorably moves on and a roulette player plays more and more decisions, the odds of winning at roulette begin to take shape. It will never be exact, but the wins and losses will come close to the mathematical calculation.

Is there a way to play the short term differently than the long term? No, the odds and probabilities of winning roulette are the same whether you play one round or thousands of them. This is another factor that some roulette players overlook, as many think they can cheat the math. I can not. You can’t. Everyone else can’t either.



The odds of winning in roulette work the same for every bet in the game. Let’s just take the always same money bet on red/black. Betting is known as “even money” because a win pays out one unit for every unit wagered. However, the odds and odds of betting are not one-to-one.

Let’s say you bet on red. There are 18 red numbers and 18 black numbers. They want red to win; You don’t want it to hit black. However (and this is IMPORTANT) you don’t want it to hit 0 or 00 on the American wheel either. These also lose the setting.

Here are the odds: You win 18 times and lose 20 times on the American Double Zero reels. In the European One Zero Wheels you will win 18 times and lose 19 times.

What are the odds of winning at roulette here? They are 20 to 18 (or 10 to 9) on the double zero wheels and 19 to 18 on the European one zero wheels. Since the payout is even, the American wheel shortens you by two units, meaning 38 to 2 shows the advantage at 5.26 percent; while the European one-zero wheels have an advantage of 2.70 percent.
