What is the house edge at the casino | House edge explained

When you step into a casino, one of the first things you’ll notice is the multitude of games available to play. From slot machines and table games to sports betting and poker, there is something for everyone. However, what many people may not realize is that every game in a casino has a built-in advantage for the house, known as the house edge.

The house edge is an important concept to understand when it comes to gambling at casinos. It represents the statistical advantage that the casino has over the players in a particular game. Today we will explain what the house edge is, how it works, and provide examples of popular casino games and their associated house edges.

What is the House Edge?

The house edge is the mathematical advantage that a casino has over the player in a particular game. It is typically expressed as a percentage of each bet that the casino expects to keep over the long term. For example, a house edge of 5% means that for every $100 bet, the casino expects to keep $5 as profit.

The house edge is built into the rules of the game and is calculated based on the probabilities of each possible outcome. This means that even if you win some bets, the casino will still make a profit over time.

How does the House Edge Work?

The house edge works by ensuring that the payouts offered by the casino are less than the odds of winning. For example, in a game of roulette, there are 38 possible outcomes (1 through 36 plus 0 and 00), but the payout for a winning bet on a single number is only 35 to 1. This means that if you bet $1 on a single number and win, you will receive $35, but if you lose, the casino keeps your $1.

The house edge in roulette comes from the fact that there are 38 possible outcomes, but the payout is only 35 to 1. This means that over time, the casino will keep an average of $2.70 for every $100 bet. This may not seem like a lot, but over millions of bets, it can add up to significant profits for the casino.

Calculating the House Edge

The house edge is calculated using complex mathematical formulas that take into account factors such as the game’s rules, payout structure, and probability of winning. To calculate the house edge, the casino will determine the expected value of each possible outcome in the game. This involves multiplying the probability of each outcome by the payout for that outcome. The sum of all these values represents the expected value of the game.

Once the expected value has been determined, the casino will subtract it from 100% to get the house edge. For example, let’s say a game has an expected value of $0.95 for every $1 bet. The house edge would be calculated as follows:

100% – ($0.95/$1 x 100%) = 5% house edge

The House Edge in the Most Popular Casino Games

Now that we understand what the house edge is and how it works, let’s take a look at some examples of popular casino games and their associated house edges.

How Does the House Edge Work in Slot Machines?

Slot machines are one of the most popular games in a casino, and they also have one of the highest house edges. The house edge in a slot machine is typically between 2% and 15%, depending on the specific machine and the casino.

The house edge in a slot machine is based on the payout percentage. The payout percentage is the percentage of money that a machine pays out to players over time. For example, if a machine has a payout percentage of 95%, it means that over time, the machine will pay out $95 for every $100 that is wagered.

However, the payout percentage does not take into account the house edge. The house edge is built into the machine and is subtracted from the payout percentage. For example, if a machine has a payout percentage of 95% and a house edge of 5%, the actual payout percentage is 90%. This means that over time, the machine will pay out $90 for every $100 that is wagered, and the casino will make a profit of $10.

The house edge in slot machines can be difficult to calculate because there are so many different types of machines and payout structures. However, in general, the house edge in slots can range from around 2% to 10% or more.

How Does the House Edge Work in Table Games?

Table games such as blackjack, roulette, and craps also have a house edge. The house edge in table games is typically lower than in slot machines, but it can still range from 1% to 5%, depending on the specific game and the casino.

The house edge in table games is based on the rules of the game and the odds of winning. For example, in blackjack, the house edge is based on the fact that the dealer always acts last. If the player busts, the dealer wins, regardless of whether the dealer would have also busted. This gives the dealer a mathematical advantage.

Roulette

As mentioned above, the house edge in American roulette is 5.26% on all bets except for the 5-number bet, which has a house edge of 7.89%. In European roulette, which has only one 0 instead of two like in the American version, the house edge is 2.70%. More about the Roulette house edge.

Blackjack

The house edge in blackjack can vary depending on the specific rules of the game being played. However, in general, the house edge is around 0.5% to 1% when basic strategy is used. This means that for every $100 bet, the casino expects to keep $0.50 to $1 as profit.

Craps

The house edge in craps can also vary depending on the specific bets being made. The pass line bet, which is one of the most popular bets in craps, has a house edge of 1.41%. The don’t pass bet, which is essentially the opposite of the pass line bet, has a slightly lower house edge of 1.36%.

Video Poker

The house edge in video poker can vary depending on the specific machine being played and the player’s skill level. However, in general, the house edge in video poker can be as low as 0.5% to 1% when optimal strategy is used.

Conclusion

In conclusion, the house edge is a concept that plays a crucial role in determining the profitability of a casino game for the house. It refers to the advantage that the casino has over players, and it is typically expressed as a percentage of the total amount wagered. While the house edge varies from game to game, and even from bet to bet within a game, it is always present and serves as a source of revenue for the casino.

Understanding the house edge is essential for anyone who wants to gamble at a casino. By knowing the house edge, players can make informed decisions about which games and bets to play, and they can manage their bankroll more effectively. It is also important to keep in mind that the house edge is based on statistical probability, which means that over time, the casino is likely to come out ahead.

Ultimately, while the house edge may seem like an obstacle for players, it is an essential component of the casino industry. Without the house edge, casinos would not be able to operate and provide the entertainment and excitement that millions of people enjoy every year.
