How Do Casinos Make Money on Blackjack?

Have you ever wondered how casinos and slot sites make money on blackjack? After all, they have to pay out the winnings, right? Well, the answer is surprisingly simple, and it's all thanks to the house edge. 

In this article, we'll explore how casinos make money on blackjack, how the house edge works, and whether you can beat it. 

Do Casinos Make Money On Blackjack?

Blackjack is a popular casino game that is enjoyed by millions of players around the world. It is a game of strategy and skill, where players attempt to beat the dealer by getting a hand closer to 21 without going bust.

So, yes, casinos make money on blackjack, and the main reason is the house edge. The house edge is the casino's advantage over the players in any given game, and it is expressed as a percentage. 

For example, if a casino has a house edge of 2%, it means that for every £100 that players bet, the casino can expect to make £2 in profit. The house edge is achieved through a combination of factors, including the game's rules, the number of decks used, and the payouts for winning hands. 

For example, if a casino uses a single deck of cards, the odds of hitting a natural blackjack (an Ace and a 10-value card) are higher, which can decrease the house edge. On the other hand, if the casino pays out less for a winning hand, such as 6 to 5 instead of 3 to 2, this can increase the house edge.  

The house edge comes from the fact that if you go bust, the dealer doesn't have to play their hand. If you go bust, the house automatically wins. 

How Does The Casino Make Money Off Blackjack? 

The answer lies in the house edge. That is a mathematical advantage that the casino has over the player, and it's built into the game's rules. The house edge for blackjack varies depending on the specific rules and payouts, but it typically falls between 0.5% and 2%. 

That may not sound like much, but over time, it can add up to a significant amount of money for the casino. Another factor contributing to the casino's profits in blackjack is how the game is structured. The dealer must follow a strict set of rules for when to hit and stand, which the casino can use to its advantage. 

Can You Beat The House In Blackjack?

As much as we'd love to walk away from the Blackjack table with our pockets overflowing with winnings, the truth is that the odds are stacked against us. The casino has the advantage and always wins in the long run. However, that doesn't mean that it's impossible to come out ahead. 

One of the most effective strategies is to learn basic Blackjack strategy and always play according to the optimal strategy for the game's specific rules. That can reduce the house edge slightly compared to playing without a strategy. 

Another popular strategy that players often use is card counting, which involves keeping track of the cards that have been played and using that information to make more informed decisions about when to hit and when to stand.  

While card counting can be effective, it's also prohibited in many casinos, and those caught using this technique may be banned from those casinos. 


In conclusion, while the house edge in blackjack gives the casino an advantage over the player, it's not impossible to beat the house. Implementing a basic blackjack strategy is the most effective way to reduce the house edge and increase your chances of winning.

However, it's important to remember that blackjack is a game of chance, and no matter how skilled you are, there will always be a certain amount of chance involved in the outcome of each hand, and nothing is guaranteed. So enjoy the game, and remember to play responsibly.
