Before placing real money down on any bet, it’s a good idea for every casino player to understand the ins and outs of the full betting process. A broader wealth of knowledge lets players make more informed choices, providing a well-rounded experience free of surprises.
One of the key aspects that applies to every casino game is what is called the house edge. Simplified as much as possible, this is the profit that an online casino expects to make from a game on average. The house edge is expressed as a percentage and will vary between games and casinos.
For an example of what house edge in casinos provides, consider a player who starts with £100 playing in a game with a 2% house edge. On average, this house edge would mean that the casino expects to earn £2 should the player wager the full £100 amount.
This house edge is how casinos stay profitable. Though some players might end up winning big, the average means the house can still keep funding its operations.
Before we take a deep look at exactly what the house edge is in casinos in specific games, we also recommend our readers explore our Safer Gambling Portal. This section explores key information about keeping betting secure and provides resources to anyone who feels in need of support.
Blackjack House Edge
The house edge in blackjack is often some of the lowest in casino gaming. Blackjack house odds can reach lower than 0.5%, and this applies to both online blackjack and physical versions. European blackjack will tend to offer a lower house edge than American blackjack, whereas something like Switch Blackjack will lie somewhere in the middle.
Blackjack is one of the games where the house edge can vary even with the same version of the game, depending on how it is handled by the casino or software provider. This occurs because blackjack games can slightly change house rules, most commonly seen with different numbers of used decks.
The more decks are included, the more difficult it becomes to use methods like card counting. Online games can also be more diligent about shuffling because they rely on RNG and not physical decks.
For the lowest house edge in blackjack, many players will rely on blackjack strategy charts. These contain all of the more statistically beneficial moves that a player can make in any situation. Strategy cards won’t provide an edge over the house, but they will reduce risks.
Slot Game House Edge
Slot games are an interesting case in house edge because they’re built on the idea of variety. It’s common for big online casinos to feature hundreds of different types of slots, each featuring different rules, graphics, and bonuses.
Because of this, the house edge in slot games can vary significantly by title. Some titles will feature a house edge of 2%, while others can have a house edge of around 10%. Fortunately, these are all listed clearly, so players don’t need to worry about getting lost.
The house edge in slot games is also listed differently than in most other games. Rather than being called house edge, slots will call this return to player, or RTP. Like house edge, this is an average and might not apply to short-term play. Chance, as always, plays a big part. Some slots can even have RTPs change in the game when specific options are toggled by the player.
How do you calculate house edge in slots?
Players don’t need to calculate house edge, it is all provided by the slot developer. The house edge can be found within the slot game in the information or paytable section. This information can be trusted, because slots need to be tested thoroughly before they are allowed to go online.
Roulette House Edge
The house edge whether you play roulette online or on a physical table depends on the table used and the rules applied to that table. The most popular forms of roulette are the American and European versions, which feature house edges of 5.26% and 2.70% respectively. The edge is different here because the American wheel contains two losing pockets, instead of the European roulette’s one.
These wheels can then have the house edge changed further thanks to additional rules placed on top. Games like Lightning Roulette and Power UP roulette will modify tables for their gameplay, which means even if they use standard wheels, house edge may be different.
Regardless of what online casino game you choose to play, it’s possible to find more betting opportunities by taking advantage of online casino special features and offers. These can provide benefits like bonus cash and seasonal rewards which, while not changing the house edge, can open more ways to bet.
