All casino players know that the house always has the upper hand. No matter where you play or which game you play, casinos will never pay out more than they bring in. If they do so, they’ll be out of business in no time at all.
Even with a really fair game, every casino has rules that statistically favor itself and disadvantage the player. On the other hand, a casino’s house edge shouldn’t dim your hopes of winning completely.
Chances are you’ve enjoyed some amazing times at the casino despite the built-in house edge. But once you fully understand the ins and outs of the house edge, you can mitigate its effects. After reading this post, we hope that you’ll be better placed to take advantage of a casino’s house edge.
What’s a Casino House Edge?
In any specific game, the casino always has the upper hand. This is what’s called the house edge. Whether you play at a brick-and-mortar casino or an online casino like Spin City Casino NZ, the casino (or rather the house) will always have the edge.
This advantage is usually built into each game itself, so the house edge of any given game typically doesn’t vary from one casino to the next. The house edge is an insurance policy for casinos, ensuring that they make more money than they lose in the long run.
The house edge is almost always represented by a percentage. For instance, the American roulette has a house edge of 5.26%. In other words, the casino will recoup 5.26% of the cash wagered on the American roulette over the entire duration of the game.
That doesn’t mean you can’t win money playing casino games, though. Many people do win! The key to leveraging the house edge is to study it, play smartly, and manage your bankroll effectively.
Knowing the house edge from the inside out can help you choose favorable games and make better wagers overall.
How to Lower the Impact of the House Edge
As previously mentioned, each casino game comes with an inbuilt house edge, meaning that you’ll never completely avoid the house edge. However, you can take the following steps to minimize the effect of the house edge.
Choose the Best Games
Did you know that certain casino games are more favorable to play than others? While Keno is tons of fun, it has a ridiculously high house edge of about 35%. You can stretch your bankroll a lot if you wager the same amount of money on games such as blackjack.
Choose Favorable Odds
Finding games with a low house edge is worth your time and money. For example, playing blackjack means you can expect 3:2 payouts. If you choose to play roulette, go for the European or French version.
Play with a Plan
Playing with a strategy can help you lower the house edge. Before playing any game that requires strategy, be sure to work on your strategy.
Understanding Game Odds
Game odds show the probability of a specific outcome and vary from casino game to casino game.
The whole idea of odds is simple: In games that require skill, you can work out the probability of specific outcomes in a given game and thus make the move that’s most likely to directly influence the outcome and make you win. Avid poker fans know this so well!
When you play skill-based casino games like craps or blackjack with strategy, you can raise your odds (chances) of winning. Therefore, you’ll decrease the chances of the house winning as you’re using the optimal, math-based strategy.
Not all games give you the opportunity to raise your chances of winning via strategy, though! Some, like slots, are based only on luck. However, you can still work out the odds of a specific outcome and choose the way you want to bet.
Casino Games with the Best Odds
Generally speaking, blackjack, craps, baccarat, video poker, and roulette offer the best odds of winning. If you play any of these games with skill, you could slash the house edge to around 0.5% to 1%.
As great as that sounds, learning how to make the most of your betting odds requires hard work. You’ll need to study odds in detail and practice harder. And once you’re playing, do all you can to avoid mistakes.
More often than not, the average gambler doesn’t study odds and put them into practice. Therefore, they often play with a high 2% to 4% house edge. Some games, like craps or progressive slots, can have an 8% to 15% house edge.
The Bottom Line
Although every casino has the upper hand in every game, the house edge differs significantly from game to game. Table games typically offer higher odds but with considerable house edges, while slots have high house edges and low odds of winning.
The role of maths in casino games can be complicated, but understanding the house edge and game odds can help you make better decisions when gambling. Ultimately, be sure to gamble responsibly and only bet what you can afford to lose.
