The house edge of casino games varies greatly with the game. The calculation of the Roulette house edge was a trivial exercise; for other games, this is not usually the case. In games that have a skill element, such as Blackjack or Spanish 21 , the house edge is defined as the house advantage from optimal play without the use of advanced techniques such as card counting or shuffle tracking , on the first hand of the shoe the container that holds the cards.
The set of the optimal plays for all possible hands is known as "basic strategy" and is highly dependent on the specific rules, and even the number of decks used. Good Blackjack and Spanish 21 games have to house edges below 0. Online slot games often have a published Return to Player RTP percentage that determines the theoretical house edge. Some software developers choose to publish the RTP of their slot games while others do not.
The luck factor in a casino game is quantified using standard deviation SD. The standard deviation of a simple game like Roulette can be simply calculated because of the binomial distribution of successes assuming a result of 1 unit for a win, and 0 units for a loss. Furthermore, if we flat bet at 10 units per round instead of 1 unit, the range of possible outcomes increases 10 fold.
After enough large number of rounds the theoretical distribution of the total win converges to the normal distribution , giving a good possibility to forecast the possible win or loss. The 3 sigma range is six times the standard deviation: three above the mean, and three below. There is still a ca. The standard deviation for the even-money Roulette bet is one of the lowest out of all casinos games.
Most games, particularly slots, have extremely high standard deviations. As the size of the potential payouts increase, so does the standard deviation. Unfortunately, the above considerations for small numbers of rounds are incorrect, because the distribution is far from normal. Moreover, the results of more volatile games usually converge to the normal distribution much more slowly, therefore much more huge number of rounds are required for that. As the number of rounds increases, eventually, the expected loss will exceed the standard deviation, many times over.
From the formula, we can see the standard deviation is proportional to the square root of the number of rounds played, while the expected loss is proportional to the number of rounds played. As the number of rounds increases, the expected loss increases at a much faster rate.
This is why it is practically impossible for a gambler to win in the long term if they don't have an edge. It is the high ratio of short-term standard deviation to expected loss that fools gamblers into thinking that they can win. The volatility index VI is defined as the standard deviation for one round, betting one unit. Therefore, the variance of the even-money American Roulette bet is ca. The variance for Blackjack is ca. Additionally, the term of the volatility index based on some confidence intervals are used.
It is important for a casino to know both the house edge and volatility index for all of their games. The house edge tells them what kind of profit they will make as percentage of turnover, and the volatility index tells them how much they need in the way of cash reserves. The mathematicians and computer programmers that do this kind of work are called gaming mathematicians and gaming analysts.
Casinos do not have in-house expertise in this field, so they outsource their requirements to experts in the gaming analysis field. From Wikipedia, the free encyclopedia.

Then verify how many of those bets have worked well. If it is 50 percent or less, the news is not good. However, if it is over 50 percent then, in general, you pick your bets correctly. We all wonder how come some people manage to win in sports betting. That is the same as asking how the Y in the equation above is larger than 1.
The answer of course lies on X and Z. Thus, in order Y to become larger than 1, either X or Z should increase. In the first case, odds comparison is crucial, while in the latter we should work on the parameters and variables of our system. You can read more about the relationship between the odds and probability in the article about how we select the right bets online.
We have now demonstrated how a single mathematical equation distinguishes winners from losers. There are quite a few posts that I read online from time to time that advise players not to follow the statistics, if they want to win in sports betting. They claim that statistics are there to be challenged, as historic data and the frequency of a team scoring, for example, do not have any effect on our sports betting performance. As they say:.
Indeed, it is a totally respectable view, no objection on that. By completely rejecting the notion of statistics in sports betting is like deploring those who follow it. Moreover, we should consider the fact that in every sport event, statistics are reported during the event. At the same time, major sports news sites keep statistical data for many years to come.
Yet you might say: well Jim, you already answered that question yourself. Statistics just sell to a whole lot of people who think they may become winners following statistical models. They are giving them the necessary hope to keep them into the game, to keep them interested. This is indeed an explanation that perhaps I should write about in the future. Having said that, I must also mention that at times betting systems emerge, which rely exclusively on the statistical analysis of the games.
What the heck, a part of these allegations must be true. Nevertheless, statistics in sports betting are applied extensively when building or improving a particular betting system. Now, I am not talking about the input variables of a system, such as statistics used in tennis matches. A system that makes 5 points out of a sample of bets may be satisfactory. Yet, I would rather have a system that makes points tested on a sample of 10, games!
And that is where mathematics and statistics make a huge difference in sports betting.

The correct term is the balance, reaching your betting balance through a calculation, or in this case, a subtraction. The difference between the profits and the losses , or the difference between the money invested and the returns. The ROI or Yield are also accounting ways that the bettors must know how to utilize, formulas to calculate the ROI and Yield are important for you to monitor your path as bettors. The ROI formula is: returns minus the cost divided by the investment. Utilizing the ROI formula above, we have:.
On this purely illustrative example, the Return Over Investment was 9 times the initial investment. If previously the math was easy to do, here it requires more mathematical complexity. Simple formulas and simple calculations. The internet is full of articles with mathematical formulas.
Poisson distribution is very commonly utilized in sports betting. In the probability theory and statistics, the Poisson distribution is a probability distribution of random discrete variable that expresses the probability of a series of events taking place on a certain period of time in case those events occur independently from when the last event happened.
Other tools we can utilize in statistics to process data should be considered by you whether you utilize them or not. Variance, for example, standard error or standard deviation, mode and even median. These are concepts you can utilize on your statistical analysis.
But the Kelly criterion is something that is being utilized for sports betting and it basically has to do with a probability theory. The Kelly Criterion gives us a different advantage over the other betting methods such as Fibonacci and arbitrage methods, because it represents a lower risk. On the probability theory and on the intertemporal choice portfolio, Kelly criterion, Kelly strategy or Kelly formula is a formula utilized to determine the ideal size of a betting sequence, in order to maximize the wealth logarithm.
On most of the gambling scenarios and some investment scenarios under simplifying assumptions, the Kelly strategy will do better than any other essentially different strategy in the long term which means, on a period of time where the number of bets that are successful match the probability of any bet being successful.
Practical use of the formula. Questions you will have to ask yourself before making any bet. Why and how much? Something I utilize more and more, the models of linear regression for me, as a bettor, serve to show me a lot of things. In statistics or econometrics, linear regression is an equation to estimate the conditional expected value of a y variable, given the values of some other x variables. Notice that the more data you can put on a regression, the more common points the line finds right?
Well, I leave many of you reflecting with this article, but it was only made for you to understand that in the sports betting world, mathematics and especially statistics and data processing is becoming more and more of a reality.
These topics are complex, and they might have several interpretations and can be used on countless situations. Each bettor, when using them, will always do it on their favour, for their own method. Your email address will not be published. There are obviously, two main issues with this one; no-one has infinite wealth and most bookmakers have maximum bets.
So, in an expected long losing sequence , this could really damage your chances of regaining profits. Review this betting system and other online sources with extreme caution. The Labouchere betting strategy is sometimes compared to the Martingale betting system, which is a way to reduce the large risks associated with the martingale strategy. It works in a similar fashion, but you decide on the amount of money you want to win ahead of time, divide that number by ten and then plan to win that number with each bet.
As you can imagine, the best will sometimes lose, so if you lose, you need to win that money back on top of the amount of money that you want to win. This process then repeats until conclusion you win your bets, or you continue losing. However, this is not the easiest approach and can be subject to significant losing periods. This is another mathematical betting strategy, which requires you to understand the odds and their relationship to potential profits and losses! Hopefully, this post makes sense as there is more than one staking and mathematical betting strategy, which can alter the stakes and the returns.
It can sometimes become confusing, so feel free to send us a message and we will happy to explain further Good luck! Tags: betting strategy. What does each way mean in football betting?

Popular mathematical sports betting systems and staking strategies The following list of betting strategies are all areas of consideration for any newbie and experiences bettor that may not have considered different approaches before risking money in a variety of situations. Stake based strategies Staking is the main aspect of sports betting and the stake controls the amount of money wagered and ultimately, won and lost throughout the entire process.
Level stakes betting This does what is says on the tin, the amount of money is based purely on a set value; many bettors will use a simple number based on what they feel comfortable risking with the bookmakers, rather than looking at their overall bankroll and using a percentage of the bankroll, as described below: Variable stakes betting If your bankroll is divided into equal 10, 20, 50 or segments, this would then provide a level stakes for the following percentages of your bankroll.
Percentage of bankroll at risk. Kelly Criterion betting The Kelly Criterion is explored in detail within a dedicated blog post, which provides you with a clear view of how you can use this mathematical staking approach to protect your funds and increase the upside when your bets are successful. Return based strategies Return based betting strategies are more concerned with the amount of money return to the sports bettors than the specific system.
Arbitrage betting Is a technique that can be easily confused with matched betting, but if you can tell the difference between arbitrage betting and matched betting , you have the possibility to secure a better long-term understanding of football and sports betting. Pure mathematical betting strategies A couple of mathematical betting systems and strategies are highlighted within this section, so you can view the best options for your selections.

In other words, the median of a long series of coin tosses is 1. To my surprise, the repeat median of long series of pick-3 drawings was not It was closer to I checked it for series of real drawings and also randomly generated drawings. Then I checked the median against series of 10 thousand drawings. The median of the skip was always close to Do not confuse it for the median combination in the set.
That value of the median is, in fact, either or The correct expression is 4,9,9 or 4 9 9 or 5,0,0 three separate digits. What is that median useful for, anyway? Among other properties, the skip median or median skip shows that, on the average, a pick-3 combination hits in a number of drawings.
I studied theory of probability gambling mathematics too! Some things get imprinted on our minds. Such information becomes part of our axioms. An axiom is a self-evident truth, a truth that does not necessitate demonstration. We operate with axioms in a manner of automatic thinking. I have never found useful to work with very, very small numbers in probability. How about the reverse?
This is a very large number. It is almost certain that my pick-3 combination will not hit the very first time I play it. How about not hitting two times in a row? Still, a very large number! I reversed the approach one more time: What is the opposite of not hitting a number of consecutive drawings? It is winning within a number of consecutive drawings. The knowledge was inside my head.
Unconsciously, I used Socrates' dialectical method of delivering the truth. His mother delivered babies. I also followed steps in De Moivre formula. Thus, my relation became: 0. Thus, the parameter I call the FFG median is between and for the pick-3 lottery. I realized I had the liberty to select whatever degree of certainty I wanted to, and only had to calculate N. The only unknown is N: the number of consecutive drawings or trials that an event of probability p will appear at least once with the degree of certainty DC.
The rest is history. Unintentionally, it might sound cocky. Just refer to it as FFG. Nothing comes with absolute certainty, but to a degree of certainty! It saddened me first, but we must come to grip with reality. The humans fictionalize because we feel we can't live without the comfort of absolute certainty. In the long run, my edge in what I do is far greater than the edge that you could hope to gain in any other speculative market. In order to beat the juice and win in sports betting, a bettor must employ a disciplined approach in their analysis of each game using methods that have proven to be successful in the long run.
I discuss my math models and analytical metrics in my Handicapping Methods essay , but you must realize that only the best and most knowledgeable handicappers can win more than Most of them belong to professional betting syndicates that hire teams of statisticians, wager millions every week and keep their operations secret. For instance, last year in the first season using a new NFL play-by-play model, Dr. As demonstrated above, a bettor only needs to win There is variance in sports betting, as there is in most investments, and I calculate the standard deviation to figure out how much of my bankroll I can safely wager on each game during the season to accommodate potential negative swings while having very little chance of exhausting my bankroll.
I have extensively quantified the variance that exists in sports betting, and use mathematical formulas to dictate the exact optimal amount to invest so as to maximize the ratio of profits to variance. However, despite being a combined However, the Kelly formula assumes sequential betting and sports betting usually involves simultaneous betting, which is part of the reason behind using some fraction of full Kelly to reduce risk.
If I play 2. Adjusting your bankroll after each week rather than flat betting will increase your expected return, as explained in the KC simulation section of my money management section. A basketball season with Using a conservative 1.
