In the world of gambling, there is a widely known saying that goes like this: "the house always wins." Hidden beneath this common expression lies a fundamental truth, one that is rooted in statistics and mathematics and skillfully leveraged by casinos to ensure their profitability. After all, if casinos were to simply pay out all the winnings to players without making any profit, they would face financial ruin and cease to exist. Hence, it becomes imperative for anyone who wishes to engage in betting and place their bets at the roulette table to fully grasp and internalize the concept of the casino's advantage, which is also referred to as the house edge or margin. Armed with this knowledge, players can then devise a well-thought-out strategy aimed at minimizing their potential losses and maximizing their chances of success.
The advantage of the casino may not appear significant when compared to the potential for winning, but this does not diminish its ability to gradually deplete the player's budget until it reaches zero. Many casinos employ a tactic that creates the illusion of constant winning, allowing them to accumulate profits over time. Although the casino's advantage may only become evident after numerous bets, it is always present, favoring the house. Its impact may be subtle, but it remains a constant force in the game.
In the realm of roulette, players are confronted with a myriad of betting choices. Given the abundance of options, one might assume that each bet corresponds to a distinct advantage for the casino. However, I must clarify from the outset that this notion is entirely false. In the realm of French roulette, the casino maintains a consistent advantage across all bets, regardless of their nature. Conversely, in American roulette, there exists only one bet that carries a higher casino advantage compared to the others. As the casino advantage remains constant, players have the convenience of devising strategies based on probabilities and odds, without the need for intricate calculations regarding the hypothetical long-term percentage accrued by the house for each individual bet.

Find out the casino's edge in French roulette.
Let's start by discussing the popular French roulette, a common feature in numerous European and Irish gambling establishments. This particular variation of the game consists of 37 numbers, a significant factor that directly influences the casino's advantage. In order to determine the extent of the casino's edge, we can analyze a bet placed on a solitary number. This particular wager offers a winning probability of 1 out of 37, indicating that the likelihood of losing stands at 36 out of 37. If the casino were to refrain from taking anything from the players' bets, it would need to offer a payout of 36 to 1. However, in reality, the payout is set at 35 to 1. This single unit discrepancy is precisely what provides the casino with an advantage, ensuring long-term profitability.
The casino advantage can be represented as a percentage, and the calculation is quite straightforward. To determine the casino advantage, you must solve the equation: subtract the probability of winning multiplied by the casino payout from the probability of losing, and then multiply the result by 100. Let's take a mathematical example that focuses on betting on a single number to illustrate this calculation more clearly. By plugging in the values, we get: [36/37 - (35 x 1/37)] x 100 = 2.70%. Hence, as we can observe, the unit we previously discussed denotes a casino profit of 2.70%. This profit always remains constant, regardless of other factors.
Let's take another example to showcase that the unchanging nature of the casino advantage in French roulette. This time, we'll focus on an outside bet placed on either red or black, which is the simplest to win but offers the lowest payout. We'll conduct the same computation, factoring in a winning probability of 18/37, a losing probability of 19/37, and a payout ratio of 1 to 1. The calculation would look like this: [19/37 - (1 x 18/37)] x 100 = 2.70%. Once again, we arrive at 2.70%. It is feasible to compute the casino advantage for any available bet in French roulette, but the outcome remains consistent across the board at 2.70%.
If you happen to be doubtful and desire to personally validate the casino's edge on every wager, I have prepared a concise table that outlines the likelihood of triumph, defeat, and the casino's payout for all the potential choices on French roulette.
| Bet | WIN | Loss | Payment | Advantage |
|---|---|---|---|---|
| Single Number | 1/37 | 36/37 | 35 to 1 | 2,70% |
| Couple | 2/37 | 35/37 | 17 to 1 | 2,70% |
| Triplet | 3/37 | 34/37 | 11 to 1 | 2,70% |
| Triplet | 3/37 | 34/37 | 11 to 1 | 2,70% |
| Quatrain | 4/37 | 33/37 | 8 to 1 | 2,70% |
| Sestina | 6/37 | 31/37 | 5 to 1 | 2,70% |
| Dozen | 12/37 | 25/37 | 2 to 1 | 2,70% |
| Column | 12/37 | 25/37 | 2 to 1 | 2,70% |
| Even or odd | 18/37 | 19/37 | 1 to 1 | 2,70% |
| Tall or short | 18/37 | 19/37 | 1 to 1 | 2,70% |
| Red or black | 18/37 | 19/37 | 1 to 1 | 2,70% |
The casino's edge in unique wagering options.
In French roulette, observant players may have come across unique betting options like orphans, series 5/8, and neighbors of zero. These particular bets consider the positioning of numbers on the physical wheel, rather than following the traditional arrangement on the table layout. It's worth noting that the casino's advantage remains unchanged for these special bets, as they essentially combine multiple bets into one.
Let me provide an example to better illustrate the concept at hand. The 5/8 bet series is a strategy that involves placing six chips on six specific number pairs. By doing so, the chances of winning are equivalent to those of a single pair, which is 2/37, but multiplied by the six pairs. Therefore, the overall probability of winning becomes 12/37. Conversely, the likelihood of losing is 25/37. The casino pays out at a rate of 17 to 1 for each pair. However, as the player wagers a total of six chips, the actual payout from the casino is adjusted to 2 to 1. As a result, the casino once again maintains an advantage of 25/37 - (2 x 12/37)] x 100, which is equal to 2.70%.
For orphans and neighbors of zero, the concept remains consistent as it does for other bets. By merging the fundamental wagers that compose these distinctive wagers, one can deduce that the advantage remains constant regardless of the chosen bet or combination thereof. In essence, this principle applies universally to all bets a player may opt for.
The en prison rule gives the casino an edge in this scenario.
Sometimes in French roulette, there is this special rule known as the en prison rule, which has the ability to impact the casino's advantage. This intriguing rule allows players to either replay their bet or receive half of their bet back in the event that a zero is drawn. However, it's important to note that this rule only applies to simple bets. To illustrate, let's say a player decides to bet on red and the ball lands on a green zero. In this scenario, the player has the option to either receive half of their bet back or keep the same chip on the bet for the next round without having to spend any additional money. As a result of this unique rule, the casino's advantage is significantly reduced to a mere 1.35%.
Determine the casino's edge in American roulette.
In this passage, I will discuss the slight differences between American and French roulette and how the casino's advantage is calculated. When it comes to American roulette, the casino has a slightly greater advantage compared to French roulette. To understand the casino's advantage, we need to consider the composition of the American roulette wheel, which consists of 38 numbers. Let's take a closer look at the calculation by using the example of betting on a single number. In this case, the probability of winning is 1 out of 38, while the probability of losing is 37 out of 38. Despite the differences in the wheel composition, the casino offers the same payouts as French roulette, which is 35 to 1. However, there is a difference of two units between American and French roulette.
In this case, we have a difference of two units compared to the one unit in French roulette. It's important to note that this difference also affects the casino's advantage, which is expressed as a percentage. The formula we need to use is the same as the one mentioned earlier: [probability of losing - (casino payout x probability of winning)] x 100 = casino advantage in percentage. Now, let's perform the calculation: [37/38 - (35 x 1/38)] x 100 = 5.26%.
In the realm of gambling, it becomes evident that the casino holds a higher advantage compared to the 2.70% value found in French roulette. This essentially means that over time, the casino is able to accumulate more wealth. It is important to note that the casino's advantage extends to the majority of bets in American roulette. If we were to analyze the bet on red and black once again, considering the likelihood of winning being 18 out of 38, the likelihood of losing being 20 out of 38, and a payout ratio of 1 to 1, we would come to the realization that the casino's advantage remains unchanged: [20/38 - (1 x 18/38)] x 100 = 5.26%. This particular percentage holds true for every bet, with the exception of one, which is the five-number bet.
The "cinquina," also referred to as a "sucker bet," is a specific type of wager that tends to be avoided by many players due to its higher casino advantage. This particular bet offers a winning probability of 5/38, a losing probability of 33/38, and a payout ratio of 6 to 1. By performing the necessary calculations, we arrive at the following result: [33/38 - (6 x 5/38)] x 100 = 7.89%. As evident from the computation, the casino advantage has indeed increased, which poses a disadvantage for players.
For anyone looking to independently calculate the house edge for each possible wager in American roulette, I have compiled a simplified chart that presents all the necessary data in a clear and concise manner.
| Bet | WIN | Loss | Payment | Advantage |
|---|---|---|---|---|
| Single Number | 1/38 | 37/38 | 35 to 1 | 5,26% |
| Couple | 2/38 | 36/38 | 17 to 1 | 5,26% |
| Triplet | 3/38 | 35/38 | 11 to 1 | 5,26% |
| Quatrain | 4/38 | 34/38 | 8 to 1 | 5,26% |
| Sestina | 6/38 | 32/38 | 5 to 1 | 5,26% |
| Dozen | 12/38 | 26/38 | 2 to 1 | 5,26% |
| Column | 12/38 | 26/38 | 2 to 1 | 5,26% |
| Even or odd | 18/38 | 20/38 | 1 to 1 | 5,26% |
| Tall or short | 18/38 | 20/38 | 1 to 1 | 5,26% |
| Red or black | 18/38 | 20/38 | 1 to 1 | 5,26% |
| Five | 5/38 | 33/38 | 6 to 1 | 7,89% |
Which roulette should I select to engage in the game?
Some players might ponder over which roulette to select for their gameplay after familiarizing themselves with the profit margins associated with each available bet in French and American roulette. It is evident that French roulette provides a higher likelihood of winning, owing to its lower casino edge in comparison to American roulette. Nevertheless, it is essential to highlight that the casino's advantage only becomes evident in the long run. Consequently, the longer one engages in gameplay, the more noticeable it becomes that the casino profits by deducting a percentage from the player's budget.
Winning money at roulette is not an impossible feat, despite the randomness of the game's results. In fact, in the short term, a player could place a bet on a single number and immediately win 35 times their original wager. However, it is important to note that roulette should primarily be seen as a form of entertainment, rather than a means of generating substantial profits. The unpredictable nature of the game's outcomes makes it impossible to accurately predict wins or losses, a reality that all players must bear in mind. It is worth mentioning that certain superstitious individuals hold the belief that specific roulette wheels bring luck based on factors such as the time of day, location within the casino, or even the assigned croupier. While there have been instances in the past where unscrupulous individuals have manipulated the game for personal gain, it can be confidently stated that there is no legal method that guarantees consistent victories.
