Internet 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.

Many online casinos lease or purchase their software from companies like Microgaming, Realtime Gaming, Playtech, International Game Technology and CryptoLogic Inc.

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 players 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 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. Apple devices such as iPod, iPad and iPhone cannot play Flash games as the technology is not supported.

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.

Deuce-to-Seven

Deuce-to-seven low is often called Kansas City lowball the no-limit single-draw variation or just low poker. It is almost the direct opposite of standard poker: high hand loses. It is not as commonly used as the ace-to-five low method.

As in all lowball games, pairs and trips are bad: that is, any hand with no pair defeats any hand with a pair; one pair hands defeat two pair or trips, etc. No-pair hands are compared starting with the highest ranking card, just as in high poker, except that the high hand loses. In deuce-to-seven low, straights and flushes count for high and are therefore bad. Aces are always high and therefore bad.

For example, the hand 8-5-4-3-2 defeats 9-7-6-4-3, because eight-high is lower than nine-high. The hand 7-6-5-4-2 defeats both, because seven-high is lower still. The hand 7-6-5-4-3 would lose, because it is a straight. Aces are high, so Q-8-5-4-3 defeats A-8-5-4-3. In the rare event that hands with pairs tie, kickers are used just as in high poker but reversed: 3-3-6-4-2 defeats 3-3-6-5-2.

Since the ace always plays high, A-5-4-3-2 is not considered a straight; is simply ace-high no pair it would therefore lose to any king-high, but would defeat A-6-4-3-2.

The best possible hand is 7-5-4-3-2 hence the name deuce-to-seven low, followed by 7-6-4-3-2, 7-6-5-3-2, 7-6-5-4-2, 8-5-4-3-2, 8-6-4-3-2, etc. Hands are sometimes referred to by their absolute rank, e.g. 7-5-4-3-2 #1, said 'number one'.

When speaking, low hands are referred to by their highest ranking card or cards. Any nine-high hand can be called a nine, and is defeated by any eight. Two cards are frequently used: the hand 8-6-5-4-2 can be called an eight-six and will defeat an eight-seven such as 8-7-5-4-2.

Another common notation is calling a particular low hand smooth or rough. A smooth low hand is one where the remaining cards after the highest card are themselves very low; a rough low hand is one where the remaining cards are high. For instance, 8-7-6-4-2 would be referred to as a rough eight, but 8-5-4-3-2 would be referred to as a smooth eight.

Wild cards are rarely used in deuce-to-seven games, but if used they play as whatever rank would make the lowest hand. Thus, in 7-6-Joker-3-2, the joker plays as a 4, while in Joker-5-4-3-2 it would play as a 7 a six would make a straight, and an ace would make ace-five high.

In most jurisdictions worldwide, gambling is limited to persons over the age of license in most countries where casinos are permitted.

Customers gamble by playing games of chance, in some cases with an element of skill, such as craps, roulette, baccarat, blackjack, and video poker. Most games played have mathematically determined odds that ensure the house has at all times an advantage over the players. This can be expressed more precisely by the notion of expected value, which is uniformly negative from the player's perspective. This advantage is called the house edge. In games such as poker where players play against each other, the house takes a commission called the rake. Casinos sometimes give out complimentary items to gamblers.

Payout is the percentage won by players.

Casinos in the USA say that a player staking money won from the casino is playing with house money.

Video Lottery Machines slot machines have become one of the most popular form of gambling in casinos. Recently, investigative reports have been calling into question whether the modern day slot machine is addictive. There are almost 900 casinos now in the United States, with that number steadily growing as more states seek to legalize casinos. 38 states now have some form of casino gambling. Relatively small places such as Las Vegas are best known for gambling; larger cities such as Chicago are not defined by their casinos in spite of the large turnover.

Las Vegas has the largest concentration of casinos in the United States. Based on revenue, Atlantic City, New Jersey ranks second and the Chicago region third.
