The blackjack house edge can be the lowest among all casino games, at 0.5%. That’s if you make the right selection regarding variants, rules, strategy, and decks. The house edge, also referred to as RTP, is the first reference point for every casino game, like with blackjack. This value indicates the chances of winning against the dealer.

Things are not as simple as telling you, the blackjack house edge is 0.5%. Many aspects contribute to this, which you must be aware of and use to get the best odds.

Icon House Edge in Blackjack Explained

To understand the blackjack house edge, you can think of it as the expected profit of the casino. There is a house edge for each casino game and blackjack variant, and their total indicates the long-term profits of the casino in percentages.

The blackjack house edge is 2% on average, but it can be higher or lower based on how you play the game and other aspects relating to the rules. Generally speaking, the blackjack house odds are considered the lowest across all other games. For reference, here is the average house edge of other popular games at the casino:

  • Online slots 4%
  • Video poker 2%
  • Online Roulette 3%
  • Progressives 8%

An important point relating to the house advantage in blackjack and other games is that even though the statistics are always in favor of the house, this doesn’t mean you cannot win while playing. It’s true that, on average, for every $100 wagered on the blackjack table, you would lose $2, based on the house edge. However, you could take a seat and land 10 or even 20 winning hands in the row.

The house edge and odds in blackjack will usually play out on hundreds or even thousands of rounds.

The house edge can mean different things depending on how you look at it.

Casino House Edge & Hold Percentage

For the online casinos, the blackjack house edge is the reason they exist in the first place. With blackjack statistics always in the house’s favor, they can be assured they can cover all running costs and continue offering their services without shutting down.

To get this number, online casinos hire auditors and independent testing bodies, which run continuous tests across millions of rounds. Their seals make players trust their services, despite the edge always being on the casino’s side. Each venue will also monitor how the edge plays out internally to watch out for loose or tight games that might be flawed.

Still, the actual profit for online casinos exists in the hold percentage; this is the true profit they make due to players’ errors that further increase the casino house edge.

Players’ House Edge & How to Increase It

Knowing the average edge that the casino has over you is crucial. It can help you stay grounded and not take any winnings for granted.

On top of this, the term average house edge is telling. Despite this number being 2% for blackjack, it can be higher or lower based on several factors.

Players can increase the blackjack hold by standing or hitting when they shouldn’t. To avoid this, relying on blackjack strategies, cheat sheets, calculators, and other tools is always beneficial.

Some basic rules that can help players lower the house edge of blackjack to as low as 0.5% include:

  • Play blackjack games that allow late surrendering.
  • Select variants that play with the lowest number of decks available, which usually range between 6 and 8.
  • Opt for games that pay out 3:2 for natural instead of 6:5.
  • Use basic and card counting blackjack strategies.
  • Variants that allow you to peek, split, and double down also lower the blackjack house edge
  • Play at casinos where the dealer stands at soft 17.

The above combined give you the best blackjack house edge. Lastly, you should learn the odds of blackjack for each card combination so you know when to stand or hit based on statistics.

    Ways Casinos Optimize their House Edge

    As players can take measures to lower the blackjack house edge, so can casinos. There are two standard ways they can achieve this.

    The first one is simple; the faster blackjack rounds play, the more money the casino makes. That’s because the long-term house edge favors it. In the past, casinos shuffled blackjack cards every 20 hands, and the time required for this cost them precious money. Nowadays, brick-and-mortar casinos have incorporated shoes that automatically reshuffle the deck; the same thing happens online but through a random number generator.

    The second way casinos optimize towards their edge is by monitoring how each game performs. For example, if a slot machine payouts more than it should, it is most likely to remove it. The same can happen with blackjack dealers making errors.

Icon Blackjack House Edge Myths

There is a lot of misinformation online, and that includes blackjack. Not everyone provides the complete picture regarding the house edge or other mechanics. Similarly, someone might just read the first few lines of a guide and leave the page taking for granted that blackjack has a 0.5% house edge. Word of mouth can then spread this further. Below, we will try and clear the air surrounding some of the most common misconceptions tied to the blackjack house edge.

You have better odds to win after a loss

No matter how many times the dealer wins, you go bust, etc., the chances of getting a winning hand doesn’t increase. The contrary is true since the edge will likely play out in the long run. Don’t let your feelings carry your losing streak further.

All blackjack hands or rounds have a 0.5% house edge

The lowest blackjack house edge is enjoyed by players who use blackjack strategies correctly and opt-in for the blackjack games with the most favorable rules. Not every player will enjoy a 0.5% house edge. Also, the edge is irrelevant to every given round, and the odds only depend on your and the dealer’s hand.

Blackjack dealers can lower the house edge

This is partly a misconception. It is not a valid claim when it comes to the gameplay or blackjack rules, since players and dealers must stick to them to win. Dealers benefit because they don’t gamble their own money, and their job is to follow their casino’s blackjack strategy. Essentially, they hit until they get 17. Where this myth becomes a reality is the speed of the play. If a dealer is really fast, more rounds are being played, and the house edge is more likely to be realized.

Players must count cards to win

Although card counting is a legit blackjack strategy and can help you lower the casino winning odds, it is not the only one. Players should always practice basic blackjack strategy and choose the games and real money blackjack casinos with the best rules for players. These are easier ways to boost your chances of winning.
