Walk into any casino today, and you’ll see two games dominating the floor: shiny, spinning slot machines and green blackjack tables. It’s the same with online social casinos, where free-to-play Vegas slots make up a large chunk of the online lobby, with several variations of RNG and live dealer blackjack tables to back them up.
However, before you play at your favorite casino, let’s see how house edge works and affects your chances of walking away with something.
How the House Edge Works in Casino Games
House edge refers to the mathematical advantage a casino holds in every game. If a game has a five percent edge, the casino expects to keep five dollars for every hundred you wager over time.
This doesn’t mean you lose five dollars every time you play, but across thousands of hands or spins, the math catches up.
So a slot could pay out a massive jackpot on your first spin, while you could lose ten hands in a row playing blackjack. The casino doesn’t necessarily need to beat you personally every time you play; it just needs the numbers to work over time.
Slots
Online slots use random number generators (RNGs) to select outcomes. When you hit the Spin button, the game maps an RNG output to the symbols shown on the reels.
For a given game configuration, a slot’s house edge is fixed. The system is programmed with a return-to-player percentage (RTP), and that figure determines how much of your money is paid back over time. So a slot with a 96% RTP has a four percent edge, and no decision you make changes that.
RTP and house edge are theoretical long-run averages. A single session can finish far above or below them, particularly on a high-volatility game.
Where available, look for theoretical RTP and volatility in a game’s rules, help page, or paytable. RTP describes the game’s long-run average return, while volatility describes how unevenly its results may be distributed. High-volatility games tend to pay larger prizes less often, while low-volatility games tend to pay smaller prizes more frequently.
Blackjack
Blackjack is different because its house edge depends on both the table rules and the player’s decisions. Choices such as hitting, standing, splitting, and even doubling down can shift the odds depending on what cards you’re holding and what card the dealer is showing.
If you play perfect basic strategy, you can enjoy one of the lowest house edges in any casino game.
With the correct basic strategy, the house edge can range from roughly 0.3% under very favorable rules to more than 2%. Either way, it is generally lower than what you get on slots. At a 0.5% house edge, you’re expected to lose around $0.50 for every $100 wagered in the long run. By comparison, a slot with a 93% RTP has a 7% house edge and a long-run expected loss of about $7 per $100 wagered.
But not all blackjack tables are the same, and the game’s specific rules can really affect the odds. Whether the dealer stands or hits on soft 17, for example, changes the house edge by about 0.2%.
Yes, that might not sound like much, but over thousands of hands, it adds up. Other rule variations that affect the house edge like the blackjack payout, whether you can double down after splitting, and how many decks are used.
Practical Tips for Playing Against the Edge
Now that you know what house edge means and how it affects your play, it’s time to learn some basic tips smart players use to improve the odds slightly.
Make sure you check the blackjack table rules before you sit down. A 3:2 payout for blackjack is far better than 6:5, and rules about doubling or dealer action on soft 17 can shift the edge in your favor more than you think.
Learn and stick to basic blackjack strategy. Strategy charts identify the mathematically optimal decision for each combination of player cards and dealer upcard, helping to keep the house edge as low as the table rules allow.
For slots, always look at the RTP in the info section before you spin. Aim for games with at least 96% RTP.
Pay attention to volatility on slots. High-volatility games can bring huge wins but long dry spells, while low-volatility slots pay smaller amounts more often.
Conclusion
Whether you acknowledge it or not, the house edge is always there whenever you load up a slot to play or sit at a blackjack table. Every game has one, but not all are equal, and if you want the best chance of walking away with money or at least losing less, blackjack is better than slots statistically, especially if you take the time to learn its basic strategy.
Still, the main thing is that you have fun at the end of the day, and that’s why we encourage you to play what you enjoy, but just do it responsibly with knowledge of what the casino is actually taking.
