Roulette is always the most attractive gambling in the casino because of its high payouts. Roulette provides a fair to both the banker and the players since when the dealer throws the ball, no strategy can rule it. Try asking any players to name one betting game, the most answer would Roulette.

The authentic spinning machine is a wheel with the numbered pockets which are attached to the wheel. The entire structure has made the symbol for Roulette, and this also made anyone who has never been to the casino know this game so well. Thanks to its simple rules, Roulette has become popular in both land and online casino around the world. At present, more players tend to play online, instead of land casinos. Therefore, they can concentrate and apply their strategies without being distracted by the noise.

The main purpose of all Roulette players is to guess exactly the winning number and place a correct bet in order to get an award. Therefore, the gamblers place the chips on the betting table and wait for the dealer to publicize the victorious number. **To calculate your benefit, you have to understand the table rules which you are playing on**. Even though it is controlled by the same rules, this** betting game** still has many differences which change the payouts and the odds.

### Calculations in Roulette

It is essential to realize that Roulette has 3 main variations with two diverse wheels. Roulette has the origin from French, and it was additional 2 variations, American and European. While European and French roulettes share similar rules, the American one has changed a small thing to bring benefit for the banker.

In the past, when Roulette was introduced to America, the casino owners were not welcomed because of the little baker profit. Therefore, they made a change. They added one more zero pocket, which increases the banker profit to 5.26%. However, the additional pocket is only applied to the American wheel, which means the European and the French Roulette provide only one zero pocket, which is more advantages to the player. Because of the low house profit (2.7%) and the extra winning chance, the players favor the French and European Roulette.

You should be accustomed to two terms: “probability” and “odds”. Roulette is a chance game, so you have to calculate exactly your winning chances. You will get a better view or the probable wins and losses thanks to these terms.

### The “Probability”

First, we will give a simple example to make the term clearer. This example comes from the familiar game, flip-a-coin, which the winning and losing chance is the same. This coin includes 2 sides, which stand for two distinct results: tails or heads. For example, you bet the result is head and you expect that this bet will come true. Or, you select one out of these two possibilities. Therefore, the “probability” to win is 1 out of 2 probable. The payout can be uttered as 1:2, 1 to 2, or ½.

With this basis, we can declare that **the “probability” term is connected with two numbers**. The first number is the probable chance (both win or loss). These numbers can be converted into percentages according to the formula: the first number (X) divides the second number (Y), and multiply it by 100. Or X / Y * 100. In this case, we get ½ = 0.5 * 100 = 50%. Therefore, the “probability” of heads to victory is 50%.

### Probability In All 3 Variants Of Roulette

Therefore, this term related to the amount of the probable cases, which are advantageous to the players. Go back to all the variations of Roulette. On the French and European wheel, there are 37 numbered-pockets. In case the player bet on a specific number, to calculate the probable chance, you have to apply the formula. This means you have 1 probable chance to win by 37 possible chances, so 1/37 = 0.027 * 100 = 2.7%. How about the case you wager on 2 numbers? You will have 2 probable winning chances by 37 probable chances. Therefore, you have 5.4% to win.

As you know that the American table offers 2 zero pockets, which are disadvantageous to the players. Therefore, few players favor this variant. On the American wheel, there are 28 numbered-pockets. *Cashbet168 *will propose examples with similar bets as on the European table to compare the possible chance to win. With a straight-up bet, you bet on 1 specific number, your winning possible chance is 1 by 38 probable chances. This means 1/ 38 = 0.026 * 100 = 2.63%. When the player bet on 2 numbers, the possible chance is 2 / 38 = 0.053 * 100 = 5.3%.

### The Odds

More players still confuse between the two terms “probability” and “odds”, but there is a small difference between them. **The odds mean the likelihood of a specific event to occur in contrast to the likelihood of a similar event not to happen**.

Like the probabilities, odds are denoted by two numbers. The first number represents the likelihood of the specific event to occur (similar to the role of the first one in “probability”) while the second number shows all the remaining outcomes which do not include the winning number.

Turn back to the situation of the flip-a-coin game, the probable result is just one (heads) and the remaining outcome is tails. Therefore, we can deduce that the odds of a heads to victory is 1 to 1, or 1:1.

In fact, the odds are stood for the ratios and it is not percentages.

### The Odds In All 3 Variants Of Roulette

Back to the example of a straight-up bet, the odds of the European Roulette are 1 to 36 while the odds of the American one are 1 to 37.

Actually, we have to mention that there is a small difference between these odds. We should distinguish odds for and odds against. Each experienced player has no difficulty to recognize that “odds for winning are 1:2” and “odds against winning are 2:1”.

The higher the payout, the lower the winning chances. For instance, in case you bet with a straight-up bet, it means you have to bet on only one number out of 38 possibilities (on the American wheel). So, your winning chances are 1:37 or 1 to 37… it means the odds for winning are 1:37 and the odds against winning are 37:1. In case you win, you will receive a payout of 35:1, because of the casino’s profit.

In case you bet an even-money bet such as red/black, the winning chances are 18 contrary to 20 probable risks to lose (18 black numbered-pockets and 2 green numbered-pockets), so the odds for winning are 18 to 20. The ratio is 18:18 since the casino gains a profit of 2 units. The odd/even bets are also the same since number 0 is neither odd nor even. If you wager on even numbers, your winning chances are 18 and your losing risks are 20 (both the odd numbers and two zero numbers). Therefore, the odds for winning are 18:20 and the ratio is 18:18 (the casino gains the profit of 2 units).

### The Meaning of The House Edge

The banker profit is decided by the zero pocket(s). Therefore, we can understand why the American banker profit is higher than the European one. The attendance of the double-zero pocket decreases the winning chances of the players.

In fact, profit is calculated logically. It is not a chance number that is offered by the house managers. With the presence of the second zero pocket, the possibility of the casino are 2 to 38, which equals to 0.0526. According to percentage, it is 0.0526 * 100 = 5.26%.

On the French and European wheels, this logic is similar to the American one. With the presence of only one zero pocket, there is only one chance for the banker to win the players. The same as the American roulette, we get 1 to 37, which equal to 0.027 or 2.7%.

For instance, in case you bet on a specific number on the American wheel, the winning probabilities of the players are 1 to 38, the odds are 1 to 37, and the ratio is 35:1 (after the banker gains its profit).

### Gambler’s Fallacy:

Recognize how to analyze your probable win or loss is the main strategy of this gambling. The gambler’s fallacy is considered to be the major thing that tricks more players. They think that the length of successive streaks of one victorious number or group of numbers is quite rare. For instance, in case three times the winning number is in red, it does not mean in the fourth round, the winning one will be in black. Because roulette is a chance game, the players can not guess exactly the winning number for the next round. Therefore, the top strategy is to control your bankroll strictly to avoid bankrupt.
