How Do Casinos Profit From Roulette?

Roulette has been entertaining players for centuries. However, a question that often plays on the minds of many is: How do casinos profit from roulette? This article aims to demystify the workings of this popular game, shedding light on the house edge and how it works. 

Understanding the House Edge in Roulette

At the heart of every casino game, including roulette, lies an inherent advantage for the casino, known as the 'house edge'. The house edge represents the average profit a casino expects to make from each player's bet, ensuring their profitability over time. 

In the game of roulette, this house advantage is cleverly integrated into the design of the game and the structure of the bets. For instance, if you were to place a Straight Up (single-number) bet, the chances of landing it in European roulette are 1 in 37, and in American roulette, 1 in 38. However, the payout is 35:1, which does not reflect the actual odds of winning. This discrepancy between the actual odds and the payout is the house edge. 

It is also demonstrated through the zero pocket(s), which are neutral regarding all outside bets. This means that if you bet on red, for example, the ball landing on zero counts as a loss, but even if you bet on black and it lands on zero, it is still a loss. 

House Edge: European vs American Roulette

The house edge in roulette varies depending on the version of the game. In American roulette, which features two zero pockets (0 and 00), the house edge is approximately 5.26%. This means that for every £100 wagered, the casino can expect to make around £5.26, on average. In contrast, European roulette, which features only one zero pocket, has a lower house edge of around 2.70%. 

How Is Roulette Rigged at Casinos?

Contrary to popular belief, roulette is not rigged at casinos. Both online and brick-and-mortar casinos are subject to stringent regulations to ensure the fairness and integrity of their games. For instance, online roulette games use a Random Number Generator (RNG) algorithm to determine the outcome of each spin. These RNGs are audited and tested regularly to verify their randomness. 

In physical casinos, the equipment used for roulette is tested regularly to ensure its randomness. Factors such as the speed of the wheel, the speed of the ball, air humidity, and slight imperfections on the surfaces of the ball and the wheel contribute to the randomness of the game. 

Also, casinos have no need to rig roulette; the house edge ensures them a profit in the long run, making rigging casino games an unnecessary risk. 

Why Do Casinos Always Win in Roulette?

While players may occasionally win big in roulette, the house always has the upper hand in the long run. This is due to the house edge, which ensures the casino always has a slight advantage and generates them a profit in the long run. 

However, casinos do not manipulate the outcomes of the game. Instead, the house edge is built into the game's design; it is part of the game, and no strategy can affect it. 

Can the House Edge Be Beaten in Roulette?

It's impossible to eliminate the house edge in roulette. There's also no way for players to lower a specific roulette game's house edge. However, players could opt to play European or French roulette, which have a lower house edge compared to American roulette. 

Other than that, there are a few things players could do to potentially increase their chances of winning, such as choosing to place outside bets, which offer a higher probability of winning by covering more numbers, but they offer lower payouts than inside bets. However, this doesn't affect the house edge in any way. 

It's important to remember that no strategy can guarantee a win. The best approach is to manage your budget effectively, set realistic expectations, and always gamble responsibly. 


In conclusion, while it's possible to win in roulette, the house edge ensures that the casino always wins in the long run. Therefore, it's vital to play responsibly and keep your expectations in check. There's no guaranteed way to win at roulette. It is a random game of chance with a fixed house edge. So, set a budget, stick to it, and never bet money you aren't comfortable losing.
