What Is the Casino House Edge? How Does It Work?

house edge in online casino games

Casinos should be able to pay out the gamblers who win, give bonuses to keep them engaged, cover the payments of employees, and still remain profitable. This means that gamblers have a great chance to win, but the cumulative income for the casino is lower than its expenses. It’s how all businesses work.

That’s why the gambling venue has to have a casino house edge over its players. It’s calculated on an average, as it differs.

What’s the Online House Advantage

The website’s lead is not set by individual casinos. It’s a mathematical calculation that results from the game’s rules. The players have the same chances to win roulette, whether they play online or in a “land” casino.

This is why it’s important to play games by reputable and licensed game providers. They program the games to give you the same odds as the ones that you’d play with an actual dealer. Instead of being focused on delivering the biggest casino house edge, they focus on fair play.

How Is the Casino House Edge Calculated

calculate house edge

The calculation is not simple, and it depends on the game’s rule.

For roulette, it’s easy to calculate the edge. But it’s much harder to calculate the casino Texas Holdem house edge, since your chances change with the cards you get and the moves you make. The gamblers should understand that a welcome bonus does not lower the site’s chances to earn money. Even though the casino gives you free money to play with, it also gives you playthrough requirements, so it can stay profitable on the long term.

Let’s see an example of how the house advantage is calculated in a game that uses a single dice. In this game, you’re supposed to guess the number that you’re going to throw.

  • The dice has six sides, so you have ⅙ chance to get the number right. 
  • The casino will pay you 5 to 1, which means that you’ll get $25 if you bet $5.

This is how the casino’s edge will be calculated:

1 – ⅚ = 0,16(6)

0,16(6) x 100 = 16.67

In conclusion, the gambling venue would have a lead of 16.67%.

Difference Between a Casino’s Payout Percentage and the House Advantage

Difference Between a Casino’s Payout Percentage and the House Advantage

The casino’s edge means that on every $100 the casino gets from a particular game, it keeps a percentage. From the example from the dice game above, it would profit with approximately $16.67 out of $100 that the gamblers deposit and bet. The payout percentage is the amount that the casino pays out. In this case, this would be the calculation:

100% – 16.67% = 83.33%

Gambling sites will rarely share the exact casino house edge. However, they will share the percentage that each game pays out. If, for example, the payout for a particular online slot is 97%, it means that the site’s earning is 3% of the total amount paid by gamblers on that pokie.

The Ultimate List: Casino Games by House Edge

We’ll list the percentages for some of the most popular games in online casinos.

Keep this to mind: the edge is calculated for an extended period of time. If the edge on a slot is 3%, it doesn’t mean that the player will win 97% of what they bet. That’s ridiculous. It means that once a player wins a jackpot slot game, they will get 97% of all bets that were placed towards the cumulative jackpot amount.

Casino Hold’em 2.16%
Wild Hold’em Fold’em 6.86%
Caribbean Stud Poker 5.22%
Pai Gow Poker house edge 1.46%
