Blackjack is one of the most popular card games in the world, played both at land-based casinos and online. The game is known for its simplicity and the fact that it gives players a chance to win big.
However, as with all casino games, there is a house edge in blackjack. In this article, we will explore what the house edge in blackjack is and how it affects your chances of winning.

What Is a House Edge?
The house edge is simply the mathematical advantage that a casino has over players in any given game. It is expressed as a percentage of each bet that the casino expects to keep over time. This means that if you were to play blackjack for an extended period of time, the casino would expect to win a certain percentage of your total bets.
How Is the House Edge Calculated in Blackjack?
In blackjack, the house edge is calculated based on several factors such as:
- The number of decks used
- The rules of the game
- The dealer’s strategy
For example, if you are playing a single deck blackjack game where the dealer stands on all 17s and you follow basic strategy (the optimal way to play each hand), the house edge would be around 0.15%. However, if you are playing an eight-deck game where the dealer hits on soft 17s and you don’t use basic strategy, the house edge could be as high as 2%.
Why Does House Edge Matter?
The house edge matters because it determines your chances of winning or losing over time. While individual hands can be won or lost due to luck or skill, over an extended period of time, the house edge ensures that casinos make money from players.
- If you play blackjack for an hour with $100 bets and the house edge is 2%, the casino would expect to keep $2 for every $100 you bet. This means that over an hour of play, the casino would expect to make $40 from you.
- However, if you play blackjack for an hour with $100 bets and the house edge is 0.15%, the casino would only expect to keep $0.15 for every $100 you bet. This means that over an hour of play, the casino would expect to make only $3 from you.
Can You Beat the House Edge in Blackjack?
While it is impossible to completely eliminate the house edge in blackjack, there are strategies that can help reduce it. One such strategy is basic strategy, which involves playing each hand optimally based on mathematical calculations.
Another strategy is card counting, which involves keeping track of the cards that have been dealt to determine when the remaining cards are favorable for players. However, card counting is not illegal but casinos frown upon it and may ask players to leave if they suspect them of doing so.
The Bottom Line
The house edge in blackjack is a simple concept but one that can have a significant impact on your chances of winning or losing. While it is impossible to completely eliminate the house edge in blackjack, using basic strategy or other strategies can help reduce it and improve your chances of winning.
