Online casinos, also known as virtual casinos or Internet casinos, are online versions of traditional ('brick and mortar') casinos. Online casinos enable gamblers to play and wager on casino games through the Internet. It is a prolific form of online gambling.
Online casinos generally offer odds and payback percentages that are a bit higher than land-based casinos.[citation needed] Some online casinos claim higher payback percentages for slot machine games, and some publish payout percentage audits on their websites. Assuming that the online casino is using an appropriately programmed random number generator, table games like blackjack have an established house edge. The payout percentage for these games are established by the rules of the game.
Many online casinos rent or buy their software from companies like CryptoLogic Inc (now Amaya), International Game Technology, Microgaming, Playtech, Golden Race and Realtime Gaming.

Online casino types
Online casinos can be divided into two groups based on their interface: web-based and download-only casinos. Some casinos offer both interfaces.
Web-based online casinos
Web-based online casinos (also known as flash casinos) are websites where users may play casino games without downloading software to their local computer. Games are mainly represented in the browser plugins Macromedia Flash, Macromedia Shockwave, or Java and require browser support for these plugins. Also, bandwidth is needed since all graphics, sounds and animations are loaded through the web via the plugin. Some online casinos also allow gameplay through a HTML interface. Apple devices such as iPod, iPad and iPhone cannot play Flash games as the technology is not supported.
Download-based online casinos
Download-based online casinos require the download of the software client in order to play and wager on the casino games offered. The online casino software connects to the casino service provider and handles contact without browser support. Download-based online casinos generally run faster than web-based online casinos since the graphics and sound programs are cached by the software client, rather than having to be loaded from the Internet. On the other hand, the initial download and installation of a download-based online casino client does take time. As with any download from the Internet, the risk of the program containing malware exists.
Virtual casino games
In a virtual casino game, the outcome of each game is dependent on the data produced by a pseudorandom number generator (PRNG). This determines the order of the cards in card games, the outcome of a dice throw, or the results produced by the spinning of a slot machine or roulette wheel. PRNGs use a set of mathematical instructions known as an algorithm to generate a long stream of numbers that give the impression of true randomness. While this is not the same as true random number generation (computers are incapable of this without an external input source), it provides results that satisfy all but the most stringent requirements for true randomness.
When implemented correctly, a PRNG algorithm such as the Mersenne Twister will ensure that the games are both fair and unpredictable. However, usually the player has to trust that the software has not been rigged to increase the house edge, as its inner workings are invisible to the user. Properly regulated online casinos are audited externally by independent regulators to ensure that their win percentages are in line with the stated odds, and this can provide a degree of assurance to the player that the games are fair, assuming the player trusts the regulator.
Live dealer casino games
In a live casino game, a human dealer runs the game in real time from a casino gaming table, which can be seen via a live streaming video link. Players can make betting decisions via a console on their computer screen, and can communicate with the dealer using a text chat function.
The results of the physical transactions by the dealer, such as the outcome of the roulette wheel spin or the dealing of cards, are translated into data that can be utilized by the software by means of optical character recognition (OCR) technology. This enables the player to interact with the game in much the same way as they would with a virtual casino game, except for the fact that the results are determined by real-life actions rather than automated processes.
These games are a lot more expensive for websites to host than virtual games, as they involve a heavier investment in technology and staffing. A live casino studio typically employs one or more cameramen, several croupiers running the various games, an information technology manager to ensure that any technical hitches are dealt with swiftly, and a pit boss that acts as an adjudicator in case of disputes between players and croupiers.
In most cases this requires at least a three-room setup, comprising a live studio, a server/software room, and an analyst’s room. The configuration of these rooms varies from casino to casino, with some having several gaming tables in one room, and some having a single table in each room.
The high running costs involved with operating live dealer games is the reason why online casinos only tend to offer a handful of the most popular games in this format, such as roulette, blackjack, sic bo, and baccarat. In comparison, the running costs associated with virtual games are very low, and it is not uncommon for online casinos to offer hundreds of different virtual casino games to players on their site.
Online casinos vary in their approach to the hosting of live games, with some providing live games via their own television channel, and others offering the games exclusively via their website. In the case of televised games, players can often use their mobile phone or television remote controls to place bets instead of doing so via a computer connected to the internet. The most common live dealer games offered at online casinos are baccarat, blackjack and roulette.
Games offered
A typical selection of gambling games offered at an online casino might include:
Bonuses
Many online casinos offer sign-up bonuses to new players making their first deposit, and often on subsequent play as well. These bonuses are a form of marketing that may incur a cost (potentially justifiable in order to attract a new player who may return and deposit many more times), since the casino is essentially giving away money in return for a commitment from the player to wager a certain minimum amount before they are allowed to withdraw. Since all casino games have a house edge, the wagering requirements ensure that the player cannot simply walk away with the casino's money immediately after claiming the bonus. These wagering requirements are commonly set to be sufficiently high that the player has a negative expectation, exactly as if they had deposited and not claimed a bonus.
Casinos may choose to restrict certain games from fulfilling the wagering requirements, either to restrict players from playing low-edge games or to restrict 'risk-free' play (betting for instance both red and black on roulette), thereby completing the wagering requirement with a guaranteed profit after the bonus is taken into account.
Welcome bonuses
The Welcome bonus is a deposit match bonus on the first deposit ever made in the casino or casino group. Welcome bonuses sometimes come in packages and may be given to match the first two or three deposits (First Deposit Welcome Bonus, Second Deposit Welcome Bonus, etc.). They can also be tied to specific games, such as the Welcome Slots Bonus or the Welcome Table Games Bonus. The casino may also offer Welcome bonuses for high rollers who make an initial deposit above the standard amount limit.
Referral bonuses
There are two types of Referral bonuses: one for the Referee and one for the Referrer. The Referee gets a bonus when he or she registers an account at the casino and mentions the Referrer. The Referrer gets a bonus when the Referee completes all the requirements, such as making the deposit and wagering it a certain number of times.
Cashback or Insurance bonuses
Cashback or Insurance bonuses are offered as a percentage of all losses in the player’s previous gaming activity. Typically, only deposits that were not matched with bonuses count towards this bonus. You can additionally find websites that offer casino cashback payments based on your losses encountered while playing with one or more online casinos. Those type of cashback deals are usually paid back to players by the casino portal that offers those special cashback offers.
No deposit bonuses
The most popular form of bonus is one that can be claimed without the need to deposit any of the player's own money - known as a no deposit bonus. These bonuses are used as acquisition tools by casinos wishing to attract new players. No deposit bonuses don't always take the form of real cash, as exemplified below.
Non-cashable bonuses
Non-cashable bonuses may be called 'sticky' or 'phantom' bonuses. In both cases, the bonus forms a part of the player's balance, but cannot be cashed out. The difference between cash-able and phantom bonuses comes at cashout time. A phantom bonus is deducted from the player's balance at the moment he places his withdrawal request. For example: if you deposited $100, received a $100, played and finished the wagering with $150. If the bonus is sticky, the player will be able to withdraw just $50. If bonus is cash-able, then the whole balance is available for withdrawal.
Comp points
Comps are commonly available at land-based casinos, but also exist online. Comp points can usually be exchanged for cash, prizes, or other comps. The amount of cash given per wager is usually very small and often varies with game selection. A casino might offer three comp points for each $10 wagered on slots and one comp point for each $10 wagered on blackjack. The casino might give $1 for each 100 comp points. This example is equivalent to returning 0.3% of wagers on slots and 0.1% of wagers on blackjack. In addition online casinos may offer comps such as free tickets to online tournaments, free slots online, tickets to other special events, extra bonuses, souvenirs and pay back.
Bonus hunting
Bonus hunting (also known as bonus bagging or bonus whoring) is a type of advantage gambling where turning a profit from casino, sportsbook and poker room bonus situations is mathematically possible. For example, the house edge in blackjack is roughly 0.5%. If a player is offered a $100 cashable bonus requiring $5000 in wagering on blackjack with a house edge of 0.5%, the expected loss is $25. Therefore, the player has an expected gain of $75 after claiming the $100 bonus.
Bonus disputes
A large portion of online casino disputes relate to bonuses. Casinos may label players who win using bonuses as 'bonus abusers.' Both players and casinos may commit fraud. An example of player fraud is creating multiple accounts and using the accounts to claim a sign-up bonus several times. An example of casino fraud is changing terms of a bonus after a player has completed the wagering requirements, then requiring the player to meet the new bonus terms.[citation needed]
Fraudulent online casino operator behaviour
Fraudulent behaviour on the part of online casinos has been documented, almost exclusively by player advocacy websites and forums. The most commonly reported behaviour is a refusal to pay withdrawals to legitimate winners. An online casino with multiple confirmed cases of fraudulent behavior is often called a rogue casino by the online casino player community.
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.
Legality
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.
Australia
The Australian Interactive Gambling Act 2001 (IGA)[1] 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.[2] In June 2016, the South Australian Government became the first state or territory in the world to introduce a 15% Place Of Consumption Tax (POCT) modelled on the 2014 UK POCT.[3]
Belgium
The Belgian Gaming Act[4] went into effect in January 2011 and allows online gambling, but only under very strict conditions and surveillance.[5]
Canada
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.[6] In 2010, the British Columbia Lottery Corporation launched Canada’s first legal online casino, PlayNow, which is available to residents of British Columbia. The province of Quebec also operates a legal online casino through Loto-Québec.
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 350 gambling websites, without ever being prosecuted.[7]
Germany
A German state contract about gambling (German: Glücksspielstaatsvertrag [de]) between all 16 German states was ratified in 2008 and has been adapted in 2012. It regulates a restrictive handling of online-gambling, including a basic state monopoly on public gambling with limited exceptions for a few commercial providers. Online gambling, and other forms of public gambling, against these regulations is illegal in Germany. The state contract, its implementation in contrast to the more lenient EU legislation, and possible further changes have been controversially discussed in the public, politics, and courts.
United Kingdom
In the United Kingdom, the Gambling Bill that was passed into law in 2005 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 2014, the UK government put into law the Gambling Act of 2014 which in addition to the original 2005 law, required offshore online gambling operators catering to UK players to obtain a UK license. The new regulation required operators to pay a 15% Place of Consumption Tax (POCT), something that triggered an exodus of sorts of some operators from the British Isles. 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.[citation needed]
In 2019 the United Kingdom Gambling Commission (UKGC) announced a series of new measures that apply to online and mobile casinos to reduce underage gambling with the aim of increasing fairness and transparency.[8] The new measures will require casinos to have users verify their identity and age in order to gamble.[9]
United States
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 2006 (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 2011, 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,[10][11] 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.

Games available in most casinos are commonly called casino games. In a casino game, the players gamblecasino chips on various possible random outcomes or combinations of outcomes. Casino games are also available in online casinos, where permitted by law. Casino games can also be played outside casinos for entertainment purposes like in parties or in school competitions, some on machines that simulate gambling.

Categories[edit]
There are three general categories of casino games: table games, electronic gaming machines, and random number ticket games such as keno. Gaming machines, such as slot machines and pachinko, are usually played by one player at a time and do not require the involvement of casino employees to play. Random number games are based upon the selection of random numbers, either from a computerized random number generator or from other gaming equipment. Random number games may be played at a table, such as roulette, or through the purchase of paper tickets or cards, such as keno or bingo.

House advantage[edit]
Casino games typically provide a predictable long-term advantage to the casino, or 'house', while offering the players the possibility of a short-term gain that in some cases can be large. Some casino games have a skill element, where the players' decisions have an impact on the results. Players possessing sufficient skills to eliminate the inherent long-term disadvantage (the house edge or vigorish) in a casino game are referred to as advantage players.
The players' disadvantage is a result of the casino not paying winning wagers according to the game's 'true odds', which are the payouts that would be expected considering the odds of a wager either winning or losing. For example, if a game is played by wagering on the number that would result from the roll of one die, true odds would be 5 times the amount wagered since there is a 1 in 6 chance of any single number appearing, assuming that the player gets the original amount wagered back. However, the casino may only pay 4 times the amount wagered for a winning wager.
The house edge or vigorish is defined as the casino profit expressed as the percentage of the player's original bet. (In games such as blackjack or Spanish 21, the final bet may be several times the original bet, if the player double and splits.)
In American Roulette, there are two 'zeroes' (0, 00) and 36 non-zero numbers (18 red and 18 black). This leads to a higher house edge compared to European Roulette. The chances of a player, who bets 1 unit on red, winning is 18/38 and his chances of losing 1 unit is 20/38. The player's expected value is EV = (18/38 x 1) + (20/38 x -1) = 18/38 - 20/38 = -2/38 = -5.26%. Therefore, the house edge is 5.26%. After 10 spins, betting 1 unit per spin, the average house profit will be 10 x 1 x 5.26% = 0.53 units. European roulette wheels have only one 'zero' and therefore the house advantage (ignoring the en prison rule) is equal to 1/37 = 2.7%.
Best Online Casino Games Free
The house edge of casino games varies greatly with the game, with some games having an edge as low as 0.3%. Keno can have house edges up to 25%, slot machines having up to 15%.
Free Online Casino Table Games
The calculation of the roulette house edge was a trivial exercise; for other games, this is not usually the case. Combinatorial analysis and/or computer simulation is necessary to complete the task.
In games which 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), 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 house edges below 0.5%.
Traditionally, the majority of casinos have refused to reveal the house edge information for their slots games and due to the unknown number of symbols and weightings of the reels, in most cases it is much more difficult to calculate the house edge than that in other casino games. However, due to some online properties revealing this information and some independent research conducted by Michael Shackleford in the offline sector, this pattern is slowly changing.[1]
Standard deviation[edit]
The luck factor in a casino game is quantified using standard deviations (SD).[2] The standard deviation of a simple game like Roulette can be calculated using the binomial distribution. In the binomial distribution, SD = sqrt (npq ), where n = number of rounds played, p = probability of winning, and q = probability of losing. The binomial distribution assumes a result of 1 unit for a win, and 0 units for a loss, rather than -1 units for a loss, which doubles the range of possible outcomes. Furthermore, if we flat bet at 10 units per round instead of 1 unit, the range of possible outcomes increases 10 fold.[3]
SD (Roulette, even-money bet) = 2b sqrt(npq ), where b = flat bet per round, n = number of rounds, p = 18/38, and q = 20/38.
For example, after 10 rounds at 1 unit per round, the standard deviation will be 2 x 1 x sqrt(10 x 18/38 x 20/38) = 3.16 units. After 10 rounds, the expected loss will be 10 x 1 x 5.26% = 0.53. As you can see, standard deviation is many times the magnitude of the expected loss.[4]
The standard deviation for pai gow poker is the lowest out of all common casinos. Many casino games, particularly slots, have extremely high standard deviations. The bigger size of the potential payouts, the more the standard deviation may increase.
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 impossible for a gambler to win in the long term. It is the high ratio of short-term standard deviation to expected loss that fools gamblers into thinking that they can win.
It is important for a casino to know both the house edge and variance for all of their games. The house edge tells them what kind of profit they will make as percentage of turnover, and the variance 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 outsource their requirements to experts in the gaming analysis field.
