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.

Online casinos generally offer odds and payback percentages that are comparable to land-based casinos. 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.

Reliability and trust issues are commonplace and often questioned. Many online casinos lease or purchase their software from well-known companies like Microgaming, Realtime Gaming, Playtech, and CryptoLogic Inc in an attempt to "piggyback" their reputation on the software manufacturer's credibility. These software companies either use or claim to use random number generators to ensure that the numbers, cards or dice appear randomly.

Online casino types

Online casinos can be divided into three groups based on their interface: web-based casinos, download-based casinos, and more recently live casinos. Some casinos offer multiple interfaces.

Web-based online casinos

Web-based online casinos are websites where users may play casino games without downloading software to the 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 plain HTML interface.

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 located within 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 does exist.

Live-based casinos

Live-based casino gaming allows web players to interact with games played in a real world casino environment. Online players can see, hear, and interact with live dealers at tables in casino studios worldwide

Games offered

A typical selection of gambling games offered at an online casino might include:

* Baccarat

* Blackjack

* Craps

* Roulette

* Online slot games

* Online poker

Bonuses

Signup bonuses

Many online casinos offer signup bonuses to new players making their first deposit. These bonuses normally match a percentage of the player's deposit with a dollar maximum, and almost all online casino signup bonuses require a minimum amount of wagering before allowing a cash out. Gameplay at specific casino games might be excluded from the wagering requirement calculation.

A fictional signup bonus offer follows as an example:

* The online casino offers new players a deposit matching bonus of 100%, up to $100

* The player must wager 25 times the total amount of the deposit plus the bonus before withdrawing

* Wagers on baccarat, craps, roulette, and sic bo do not count towards meeting wagering requirements

For this particular example, this would mean that a player depositing $100 would start with $200 in his account. The player must make $5000 ($200 × 25) in wagers before being allowed to make a withdrawal.

Some bonuses require no deposit to claim them. Types of no deposit bonuses include[citation needed]:

* A no deposit in pure monetary form, for example $10.

* Free spins no deposit, this is where they allow free spins on particular games, and then allow you to keep the winnings.

* Play for a predetermine period of time with x amount of dollars.

Cashable bonuses

The most common form of casino bonuses is the cashable bonus.[citation needed] Cashable bonuses can be cashed out after completing a wagering requirement. A casino might offer a 100% match bonus up to $100 with a wagering requirement of $2000. After wagering $2000 in the casino, the player is able to cash out the $100 bonus.

Cashable bonuses often restrict play on certain games. Wagers made on roulette, baccarat, craps, and sic bo usually do not count towards the wagering requirement because these bets give the player the opportunity to simultaneously bet on winning and losing outcomes, greatly reducing variance.[citation needed] For example, betting on both red and black in roulette. Wagers on games with a low house edge, like blackjack and video poker, are also often excluded. Some casinos increase the wagering requirement above the default for low-house-edge games.

On games without raises or doubles, the expected loss while completing a wagering requirement is wagering requirement * house edge. This makes the expected gain of a cashable bonus equal to bonus - wagering requirement * house edge. House edge is defined in terms of initial bet, so the above equation does not apply to games with raises and doubles where the final bet size may be larger than the initial bet. The equation becomes bonus - wagering requirement * average loss per wager. WizardofOdds.com has proposed calling the latter average loss per wager variable "element of risk".[1] For a more precise estimate, one must also consider the benefit from being able to bet the bonus prior to completing the wagering requirement. This effect becomes noticeable when making large bets, such as betting the full balance (deposit and bonus) in a single bet. After considering this benefit and "element of risk", the formula for return becomes bonus - average wagering * element of risk.[2] If games without raises or doubles are played and the bonus is not given until completing wagering, then the formula can be simplified as bonus - wagering requirement * house edge.

Sticky bonuses

Non-cashable bonuses are often called "sticky bonuses".[3] Sticky bonuses can be bet, but cannot be cashed out. When the player makes a withdrawal, the sticky bonus is typically removed from the withdrawal total. A player might receive a 100% match sticky bonus on a $100 deposit with a wagering requirement of $2000. While meeting the $2000 wagering requirement, the player could bet both the deposit and the sticky bonus. When cashing out, the $100 bonus would be removed from the balance. If the player cashed out $300, $100 would be subtracted out, leaving $200. The player is not allowed to cash out a balance of below $100 since no cash would remain after the bonus is removed.

The benefit of a sticky bonus can be explained as financial leverage: if the player deposits $100, receives a $100 (100%) match, and then earns 50% gambling (so they now have $300), then cashes out, they have earned $100 on their initial deposit of $100, for a 100% gain: the sticky bonus has doubled or "levered up" their gain.

The average return of a sticky bonus is sometimes expressed in terms of a target gain. Average return = (chance of reaching target) * (target - bonus - deposit - wagering requirement * house edge) - (chance of not reaching target * deposit). With a target of 2x(bonus+deposit) and 50% chance of reaching the target, the equation reduces to 50% * (bonus - wagering requirement * house edge). Expressing in terms of chance of bust and "element of risk", the formula for return becomes bonus * chance of bust - average wagering * element of risk.

The sticky bonus described above that is removed after wagering is sometimes known as a "phantom bonus." There are other variations of a sticky bonus in which you do not need to exceed your original balance to make a withdrawal. Instead any win is immediately cashable.

Compare cashable bonuses/non-cashable bonuses to stake returned/stake not returned free bets.

Cash back bonuses

Cash back bonuses are given following a player loss. A portion of the player's loss is returned, often as cash. For example, a casino might offer a 25% cash back bonus each week. Any player who had a loss over the course of the week, would receive 25% of his loss back. Any player who had a win over the course of the week would not receive a bonus. Cashback bonuses are rare.[6]

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.[7] 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.

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%. In the example above, $5000 in wagering with a house edge of 0.5% will result in an expected loss of $25. Since the player received a $100 signup bonus, after subtracting the expected loss of $25, the player has an expected gain of $75.

Online casinos offer players signup bonuses as incentives to play. These are usually one-off bonuses for signing up to the casino and opening an account. The terms and conditions attached to each bonus vary but share two common features:

* Restricted games or bets.

* Wagering requirements.

Wagering requirements prevent players from withdrawing the bonus money immediately after receiving it. Before the bonus money can be withdrawn the player must wager a certain amount of money on unrestricted games. The wagering can be spread out over many bets. To meet a $2000 wagering requirement, a player could make 1000 $2 bets on blackjack, provided blackjack is not a restricted game.

Games like blackjack and video poker have a low house advantage. The house advantage for blackjack is ~0.5%. So in the example above, by playing $2000 worth of blackjack with a house advantage of 0.5%, a player is, expected to lose $10 in total. But the expected value is an average value and may be less than the actual value. Risk of ruin is an important topic that comes into play.

Assuming that the player only loses an amount close to the expected loss, and the bonus awarded to the player after meeting this wagering requirement is greater than $10 then the player profits. The process is mathematically calculated. Bad luck could cause a player to lose more than $10 playing blackjack in this situation. The run of luck is subject to variance and follows a normal distribution.

Sports betting

By taking advantage of 'free' bet promotions, users can back the event, and then lay the event on a betting exchange, at similar or same odds, thus ensuring that their 'free' bet is not a bet at all, instead more like a financial trade. No matter the outcome, it is possible (by using a betting / arb calculator) to calculate both the possible outcomes before the sporting event has started. By inputting the odds, the bet calculator then tells you what amount to bet, to ensure that whether the bet wins or loses, the return is the same.

Bonus abuse

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.

What do you need?

You need some way of making your initial deposit.  Most casinos accept Credit and debit cards, however I would only use debit, banks have been known to charge cash advance fees to players making deposits with Credit cards.

You might also want to consider using an E Wallet.  We reccommend the following:

Moneybookers

Just like an online bank really, you can make your deposits AND receive your winnings all in the same account.  Plus you have 24Hr online access.  Nearly all casinos accept Moneybookers.

I have used them since day one.  And have never had a problem.

You may need some ID, often a casino will ask for ID before they pay you.  A passport or driving license will do fine. They may also ask for proof of address. A bill showing your home address, such as a gas or water statement should be OK.

Thats about all you really need, dont forget, its always better to play with a bonus, than without one.   And never play with money you cant afford to lose.


Just to mention here, always read the terms and conditions BEFORE you play, some casinos restrict certain games from counting during bonus play.
