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: 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.

The customer service was extremely helpful in explaining everything that the project entailed. This company did an excellent job. My family and I were in the market for a hot tub.
After extensive research, we went to Pools Plus. With their advice on which hot tub was best suited for our needs we purchased an emerald spa.
The time and patience by the staff at Pools Plus was was more than expected and better than we could have asked. Pools Plus has continued to provide us with excellent customer service.
The staff was always exceptional. Last year I purchased a spa from Pools Plus. I did some research and got a great deal on my spa which I love.
The best part of my experience was dealing with Pools Plus and their staff. I look for a company that has great service and Wayne and his staff were over the top.
Excellent customer service and technical skills. Many casino gambling portals and player forums maintain blacklists of rogue casinos.
While some carry more authority than others, all blacklists constitute individual webmaster and player opinions rather than an official list from any type of regulating body.
Often, casinos use buffer sites that offer free play of their casino games but in reality use different means of deceptive strategies to redirect or lure the visitors into signing up to their services via appealing bonus offers or exclusive reward programs.
Majority of these deceptive "free" sites lead to equally deceptive casinos. Since almost all existing online casinos offer free play of their casino games, recognising whether a casino is deceptive based on whether they offer free gameplay is no longer viable.
Online gambling legislation often has loopholes that result from the rapid development of the technology underpinning the development of the industry.
Some countries, including Belgium, Canada, Finland and Sweden have state gambling monopolies and do not grant licenses to foreign casino operators. According to their law, operators licensed on the territory of these countries can only be considered legal.
At the same time, they can't prosecute foreign casino operators and only block their sites. Players in these countries can't be punished and can gamble at any site they can access.
The Australian Interactive Gambling Act IGA  criminalises the supply of online casino games by an operator anywhere in the world to persons located in Australia.
It only targets operators of online gambling sites, resulting in the curious situation that it is not illegal for a player in Australia to access and gamble at an online casino.
No operator has even been charged with an offence under the IGA and many online casinos accept Australian customers.
The Belgian Gaming Act  went into effect in January and allows online gambling, but only under very strict conditions and surveillance.
The Canadian criminal code states that only provincial governments and charitable organizations licensed by provincial governments may operate a casino in Canada.
It also prohibits residents from participating in any lottery scheme, game of chance, or gambling activity not licensed or operated by a provincial government.
Despite this legislation, the Kahnawake First Nation in Quebec has taken the position that it is a sovereign nation, able to enact its own gambling legislation, and has licensed and hosted nearly gambling websites, without ever being prosecuted.
The European Commission via the "EU Pilot" scheme recently questioned Germany about what steps it plans to take to eliminate the current sports-betting monopoly operated by state-owned Oddset and to also reconsider its stance on prohibiting online casino and poker games due to the huge gray market currently existing — and prospering — in the country.
Latest strike to the German Legislative was from Court of Justice for the European Union CJEU recently ruled against the country's restrictive online gaming laws where is clearly stated"Further to a judgment of the Court from which it can be inferred that a national law is not compatible with EU law, all organs of a Member State concerned are under an obligation to remedy that situation," Judge Advocate General Szpunar stated in year.
In the United Kingdom, the Gambling Bill that was passed into law in tends to all matters of online gambling, permitting online betting sites to have a Remote Gambling Licence in order to offer online betting to UK citizens.
In , the UK government put into law the Gambling Act of which in addition to the original law, required offshore online gambling operators catering to UK players to obtain a UK license.
However, this exodus did not last long in most cases as the benefits outweighed the stumbling blocks, due to the UK being a major market for online gambling.
In the United States, the legality of online gambling is debated and can vary from state to state. The Unlawful Internet Gambling Enforcement Act of UIGEA limits the ability of banks and payment processors to transact with internet gambling sites that are unlawful under any federal or state law.
However it does not define the legality or otherwise of an internet based gambling site. It was commonly assumed that the Federal Wire Act prohibited all forms of online gambling.
However, in December , the United States Department of Justice released a statement clarifying that the Wire Act applied only to sports betting sites and not to online casinos, poker, or lottery sites,   leaving the definition of legality up to individual states.
Certain states such as Nevada, Delaware, and New Jersey have started the process of legalising and regulating online gambling and it is expected that regulation will continue on a state by state basis.
