Online Casinos

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 is established by the rules of the game.

Online casinos can be divided into two groups based on their interface: web-based and download-only casinos. Some casinos offer both interfaces.

Some casinos offer 'Live gaming', either exclusively, or as part of a wider online casino offering. In live online casinos, popular casino games such as roulette and blackjack are dealt by real dealers in casino studios, in an attempt to convey more of the atmosphere of a physical casino. Player actions including chat such as 'hit' in the game of blackjack may be transmitted to the dealer; in some online casinos more than one player may 'sit' at a particular 'seat' on the table, and in this case there is no interactivity between player and dealer. The question of which player s requested the extra card that the dealer dealt and which chose to 'stand' will be handled by the software. It is usual for players to be able to observe a video feed of the action, and equally common for players to opt to turn it off, if they lack the bandwidth - as the cards are read by OCR and other technology, the video feed is only ever a visual cue.

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 plug-ins Macromedia Flash, Macromedia Shockwave, or Java and require browser support for these plug-in. In addition, bandwidth is needed since all graphics, sounds and animations are loaded through the web via the plug-in. Some online casinos also allow game play through a plain 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 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. Still the graphics and sounds at download-based online casinos are most of the time much better than those at web-based online casinos.

Compulsive Gambling

Many people enjoy gambling, whether it's betting on a horse or playing poker on the Internet. Most people who gamble don't have a problem, but some lose control of their gambling. Signs of problem gambling include

Always thinking about gambling
Lying about gambling
Spending work or family time gambling
Feeling bad after you gamble, but not quitting
Gambling with money you need for other things

Many people can control their compulsive gambling with medicines and therapy. Support groups can also help.
Gambling addiction, also known as compulsive gambling, is a type of impulse-control disorder. Compulsive gamblers can’t control the impulse to gamble, even when they know their gambling is hurting themselves or their loved ones. Gambling is all they can think about and all they want to do, no matter the consequences. Compulsive gamblers keep gambling whether they’re up or down, broke or flush, happy or depressed. Even when they know the odds are against them, even when they can’t afford to lose, people with a gambling addiction can’t “stay off the bet.”

Mult-Line Slot Machines

Multi-line slot machines have become more popular since the 1990s. These machines have more than one payline, meaning that visible symbols that are not aligned on the main horizontal may be considered for winning combinations. Reel slot machines commonly have three or five pay lines, while video slot machines may have 9, 15, 25, or as many as 100 different pay lines. Most video slot machines have a themed game, some of which feature graphics and music based on popular entertainers, motion pictures or TV programs The Addams Family, I Dream of Jeannie, Happy Days, etc. with a bonus round. Most accept variable amounts of credit to play with 1 to 15 credits per line being typical. The higher the amount bet, the higher the payout will be.

There are also standard 3 to 5 reel electromechanical machines, of various types. These are the typical one-armed bandits. Since about 2005 there have been hybrid machines introduced, which combine elements of both video machines and traditional electromechanical machines.

One of the main differences between video slot machines and reel machines is in the way payouts are calculated. With reel machines, the only way to win the maximum jackpot is to play the maximum number of coins usually 3, sometimes 4, or even 5 coins per spin. With video machines, the fixed payout values are multiplied by the number of coins per line that is being bet. In other words: on a reel machine, it is to the player's advantage to play with the maximum number of coins available.

As an example, on the Wheel of Fortune reel machine created on the basis of the famous TV show “Wheel of Fortune” created by Merv Griffin, the player must play 3 coins per spin to be eligible to trigger the bonus round and possibly win the jackpot. On the Wheel of Fortune video machine, the chances of triggering the bonus round or winning the maximum jackpot are exactly the same regardless of the number of coins bet on each line.

Larger casinos offer slot machines with denominations from 1 cent penny slots all the way up to $100.00 or more per credit. Large denomination slot machines are usually cordoned off from the rest of the casino into a High Limit area, often with a separate team of attendants to cater to the needs of those who play there.

Slot machines common in casinos at this time are more complicated. Most allow players to accept their winnings as credits, which may be spent on additional spins.

In the last few years, new multi-denomination slot machines have been introduced. With these slot machines, the player can choose the value of each credit wagered the stake from a list of options. Based upon the player's selection, the slot machine automatically calculates the number of credits the player receives in exchange for the cash inserted and displays the amount of available credits to the player. For example, a player could choose to wager one dollar per game on a nickel slot machine. This eliminates the need for a player to find a specific denomination of a particular slot machine; they can concentrate on simply finding the machine and setting the denomination once they decide to play.

Recently, some casinos have chosen to take advantage of a concept commonly known as tokenization, where one token buys more than one credit. A casino can configure slot machines of numerous different denominations to accept the same type of token. For example, all penny, nickel, quarter, and dollar slot machines could be configured to accept dollar tokens. This significantly reduces a casino's inventory costs and coin handling costs. A tokenized slot machine automatically calculates the number of credits the player receives in exchange for the token inserted and displays the amount of available credits to the player. When a player chooses to collect his credits by pressing a Cash Out button, the slot machine will automatically divide the number of credits on the credit meter by the value of one token and return the result to the patron. Any remainder is known as residual credits and cannot be collected. Residual credits must be either played or abandoned.
