How Does a Casino Make Money on Roulette? It's Not 50/50

Roulette, a game of chance that has been attracting players to the gaming tables for centuries, comes with an inherent house edge. This house edge is the average profit a casino can expect from each player's bet, giving the house an advantage over the players. 

But, is it possible to beat this house edge? In this Roulette Online article, we'll delve into the workings of the house edge, potential strategies, and the prospects of possibly winning at roulette.

House Edge In Roulette Explained

The house edge in roulette is the casino's advantage over the players. It is calculated as the difference between the odds of potentially winning and the payouts offered by the casino. 

For instance, in American roulette, which features two zero pockets (0 and 00), the house edge is 5.26%. That means, for every £100 staked, the casino may earn around £5.26 in profit, on average.

On the contrary, European roulette, featuring only one zero pocket (0), has a lower house edge of 2.70%. The house edge is ingrained into the game, and no strategy can alter it. Thus, understanding the house edge can potentially aid players in making informed betting decisions.

How Does The Casino Win at Roulette?

The house edge in roulette is achieved through the game's design and the way bets are structured

For example, inside bets can offer a higher payout, but have a lower probability of winning. In contrast, outside bets can offer a lower payout, but have a higher likelihood of winning. Consequently, the house edge is accomplished by offering payouts lower than the true odds of the bet winning.

Additionally, the house gains an edge through the use of zero pockets (0 and 00 in American roulette, and 0 in European roulette). These pockets are not covered by any of the usual bets, and if the ball lands in them, all bets are lost, giving the house an advantage.

Can You Beat Roulette?

While it may be impossible to completely beat the house edge in roulette, certain methods may help in potentially reducing it.

For instance, choosing European or French roulette, which offers a lower house edge compared to American roulette can reduce the house's advantage.

Outside bets such as red/black or even/odd offer lower possible payouts but have a higher chance of landing. Additionally, having a solid bankroll management strategy and practising responsible gaming can also be beneficial.

Is There Any Guaranteed Way To Win Roulette?

Another common myth about roulette is that mathematics or physics can be used to try and gain an edge. However, this is a flawed approach for several reasons. 

Roulette is designed to be unpredictable, and it's nearly impossible to accurately predict where the ball may land. So, even if you could predict the outcome, the payouts are structured in a way that would most likely still give the house an advantage in the long run.

Play Roulette Online at Roulette Online Casino

If you're keen to put your understanding of roulette to the test, why not play roulette online at a reputable casino like Roulette Online? 

We offer a variety of roulette games, including American, European, and even live roulette. But remember, roulette, like any other form of gambling, should be enjoyed responsibly.

No betting strategy or system can change the odds in your favour. The best way to approach roulette is to enjoy the game for what it is, set realistic expectations, and always be mindful of the house edge.


In conclusion, it's crucial to remember that while you may land wins and potentially even big wins, in the long run, the house edge will almost always work against you. So, when playing roulette, keep this in mind and gamble responsibly. There's no guaranteed way to win at roulette.
