The house edge is defined as the ratio of the average loss to the initial bet. In some games the beginning wager is not necessarily the ending wager. For example in blackjack, let it ride, and Caribbean stud poker, the player may increase their bet when the odds favor doing so. In these cases the additional money wagered is not figured into the denominator for the purpose of determining the house edge, thus increasing the measure of risk. For games like Ultimate Texas Hold 'Em and Crazy 4 Poker, where there are two required initial wagers, the house edge is based on one of them only. House edge figures are based on optimal or near-optimal player strategy.
The house edge is also known as the casino advantage. And it's something that exists on every table game, lotto, or slot in a casino online or on land. House edge tells you: How much each game pays. The house edge of the US wheel is 5,26%, for European roulette the house edge is 2,7% and the French roulette uses a house edge of 1,35% but this is even bets only. The extra ‘Double Zero’ on the US wheel makes an outsized difference, almost doubling the casino house edge. All even money and 1/3rd bets lose when either zero is hit, which is. House Edge from 5% to 1.4%. Simply put, craps is one of the most exciting games going in any brick-and-mortar casino. But what about in online casinos? The many rules often mean that players are put off from trying their luck. However, craps offers one of the lowest house edges compared to other casino games.
The table below shows the house edge of most popular casino games and bets.

Guide to House Edge
- This built-in advantage is called the house edge. In numbers, it's the the percentage of the player's bet that the casino keeps as profit, over the long term. For example, in roulette house edge is about 5%. That means for every dollar bet, the casino keeps 5¢ as profit, and returns the other 95¢ to the players as winnings, on average.
- Based on typical Las Vegas Casino rules, please note variations will occur. Variations will occur depending on individual House rules and various promotions or special situations. We define true definition of House Edge as the ratio of the average loss to the initial bet.
The reason that the house edge is relative to the original wager, not the average wager, is that it makes it easier for the player to estimate how much they will lose. For example if a player knows the house edge in blackjack is 0.6% he can assume that for every $10 wager original wager he makes he will lose 6 cents on the average. Most players are not going to know how much their average wager will be in games like blackjack relative to the original wager, thus any statistic based on the average wager would be difficult to apply to real life questions.
The conventional definition can be helpful for players determine how much it will cost them to play, given the information they already know. However the statistic is very biased as a measure of risk. In Caribbean stud poker, for example, the house edge is 5.22%, which is close to that of double zero roulette at 5.26%. However the ratio of average money lost to average money wagered in Caribbean stud is only 2.56%. The player only looking at the house edge may be indifferent between roulette and Caribbean stud poker, based only the house edge. If one wants to compare one game against another I believe it is better to look at the ratio of money lost to money wagered, which would show Caribbean stud poker to be a much better gamble than roulette.
Many other sources do not count ties in the house edge calculation, especially for the Don’t Pass bet in craps and the banker and player bets in baccarat. The rationale is that if a bet isn’t resolved then it should be ignored. I personally opt to include ties although I respect the other definition.
Element of Risk
For purposes of comparing one game to another I would like to propose a different measurement of risk, which I call the 'element of risk.' This measurement is defined as the average loss divided by total money bet. For bets in which the initial bet is always the final bet there would be no difference between this statistic and the house edge. Bets in which there is a difference are listed below.
Element of Risk
| Game | Bet | House Edge | Element of Risk |
|---|---|---|---|
| Blackjack | Atlantic City rules | 0.43% | 0.38% |
| Bonus 6 | No insurance | 10.42% | 5.41% |
| Bonus 6 | With insurance | 23.83% | 6.42% |
| Caribbean Stud Poker | 5.22% | 2.56% | |
| Casino War | Go to war on ties | 2.88% | 2.68% |
| Crazy 4 Poker | Standard rules | 3.42%* | 1.09% |
| Heads Up Hold 'Em | Pay Table #1 (500-50-10-8-5) | 2.36% | 0.64% |
| Double Down Stud | 2.67% | 2.13% | |
| Let it Ride | 3.51% | 2.85% | |
| Spanish 21 | Dealer hits soft 17 | 0.76% | 0.65% |
| Spanish 21 | Dealer stands on soft 17 | 0.40% | 0.30% |
| Three Card Poker | Ante & play | 3.37% | 2.01% |
| Ultimate Texas Hold 'Em | 2.19%* | 0.53% | |
| Wild Hold ’em Fold ’em | 6.86% | 3.23% |
Standard Deviation
The standard deviation is a measure of how volatile your bankroll will be playing a given game. This statistic is commonly used to calculate the probability that the end result of a session of a defined number of bets will be within certain bounds.
The standard deviation of the final result over n bets is the product of the standard deviation for one bet (see table) and the square root of the number of initial bets made in the session. This assumes that all bets made are of equal size. The probability that the session outcome will be within one standard deviation is 68.26%. The probability that the session outcome will be within two standard deviations is 95.46%. The probability that the session outcome will be within three standard deviations is 99.74%. The following table shows the probability that a session outcome will come within various numbers of standard deviations.
I realize that this explanation may not make much sense to someone who is not well versed in the basics of statistics. If this is the case I would recommend enriching yourself with a good introductory statistics book.
Standard Deviation
| Number | Probability |
|---|---|
| 0.25 | 0.1974 |
| 0.50 | 0.3830 |
| 0.75 | 0.5468 |
| 1.00 | 0.6826 |
| 1.25 | 0.7888 |
| 1.50 | 0.8664 |
| 1.75 | 0.9198 |
| 2.00 | 0.9546 |
| 2.25 | 0.9756 |
| 2.50 | 0.9876 |
| 2.75 | 0.9940 |
| 3.00 | 0.9974 |
| 3.25 | 0.9988 |
| 3.50 | 0.9996 |
| 3.75 | 0.9998 |
Hold
Although I do not mention hold percentages on my site the term is worth defining because it comes up a lot. The hold percentage is the ratio of chips the casino keeps to the total chips sold. This is generally measured over an entire shift. For example if blackjack table x takes in $1000 in the drop box and of the $1000 in chips sold the table keeps $300 of them (players walked away with the other $700) then the game's hold is 30%. If every player loses their entire purchase of chips then the hold will be 100%. It is possible for the hold to exceed 100% if players carry to the table chips purchased at another table. A mathematician alone can not determine the hold because it depends on how long the player will sit at the table and the same money circulates back and forth. There is a lot of confusion between the house edge and hold, especially among casino personnel.
Hands per Hour, House Edge for Comp Purposes
The following table shows the average hands per hour and the house edge for comp purposes various games. The house edge figures are higher than those above, because the above figures assume optimal strategy, and those below reflect player errors and average type of bet made. This table was given to me anonymously by an executive with a major Strip casino and is used for rating players.
Hands per Hour and Average House Edge
| Games | Hands/Hour | House Edge |
|---|---|---|
| Baccarat | 72 | 1.2% |
| Blackjack | 70 | 0.75% |
| Big Six | 10 | 15.53% |
| Craps | 48 | 1.58% |
| Car. Stud | 50 | 1.46% |
| Let It Ride | 52 | 2.4% |
| Mini-Baccarat | 72 | 1.2% |
| Midi-Baccarat | 72 | 1.2% |
| Pai Gow | 30 | 1.65% |
| Pai Pow Poker | 34 | 1.96% |
| Roulette | 38 | 5.26% |

Casino House Edge Percentages
Written by: Michael Shackleford
Casinos are a place where adults can have as much fun as kids do at amusement parks. This could not be any more of an apt description because amusement parks and casinos are exactly the same—they both take as much money as they can from you and still manage to send you home happy. While casinos are all about having fun, it is important to keep in mind that, at the end of the day, casinos are in the business of making money. Though you may not understand how these establishments make money, rest-assured they are doing it every time players make wagers.
Some people think that casinos make their money by cheating players, but nothing could be further from the truth. Money is made thanks to guaranteed profit being built into every bet that is placed. This is known as the house edge.
House Edge Explained
Lowest House Edge Casino
Before we go any further, it is important to point out that two games—video poker and blackjack—do not have any house edge built into them.
The best way to simplify house edge is to explain things in terms of a simple coin toss. If, for example, you and a friend were to be placing wagers on a coin toss, you know that the odds of the coin landing on either one of the sides is an even 50%. If you wager $2 and are playing at true odds (50%=1:1), a winning bet on your part would see you win an even $2. If this same coin toss played out on the floor of a casino, you might see something like a winning bet pay out only $1.90 as opposed to an even $2. The $0.10 difference between true odds and what you are actually paid is known as the house edge. No matter how many times a player wins, they will, with each and every winning bet, be paying the casino 5%. In this hypothetical example, the coin-toss game’s house edge would be 2.5%.
You may be wondering why you have never really taken note of house edge before, and that is because casinos do well to avoid advertising just how much they are making with each turn of a card, roll of the dice, or spin of the wheel. Just like taxes, house edge is a cost you will be forced to pay whether you like it or not. After all, casinos have bills to pay too, and without house edge they would all surely go bankrupt in a hurry.
Varieties of House Edge
Casino House Edge Games
In the example above, the house edge is pretty cut and dry and is easy to understand. As you begin playing games that are more complex, the house edge can be a bit more confusing to understand. When it comes to the game of baccarat, for example, the house edge depends on the position upon which you are wagering. A bet on the bank has a very small house edge, but a bet on the tie sees the house have a very large edge.
Even now you may think that understanding what house edge is and how it is applied to your favorite games is a waste of time, but that is patently not true. Once you gain a better understanding of how house edge is applied to games you may also change your casino play to give yourself a better edge.
House Edge FAQs
Are there any casinos that do not host games with a built-in house edge?
The short answer to this question is no. House edge is the way in which casinos make their money. If a casino—online or brick and mortar—did not boast house edge, they would quickly run out of money and be forced out of business.
If a game has a high house edge should I not play it?
This is something that you must decide for yourself. Now that you know more about what house edge is and how it works, you may want to stay away from games with high casino commissions, but at the same time it is important to remember that some of the most profitable bets (if you are able to win them) also have some of the highest house edges.

House Edge In Casino Games
Sometimes you will find that a casino is raking in more per bet than standard house edge. Though this isn’t entirely common, there are some casinos who look to get one over on their players by utilizing a higher house edge. For this reason, doing your due diligence and finding out everything there is to know about a site prior to playing there is incredibly important. Through very minimal amounts of research you will be able to differentiate casinos with unfair edges and those that align with industry standards.
