CASINO

A casino is, in the modern sense of the word, a facility that houses and accommodates certain types of gambling activities. Casinos are most commonly built near or combined with hotels, restaurants, retail shopping, cruise ships and other tourist attractions. Some casinos are known for hosting live entertainment events, such as stand-up comedy, concerts, and sporting events.

The term "Casino" originally meant a small villa, summerhouse or pavilion built for pleasure, usually on the grounds of a larger Italian villa or palazzo. There are examples of such casinos at Villa Giulia and Villa Farnese. In modern day Italian, this term designates a bordello (also called "casa chiusa", literally "closed house"), while the gambling house is spelled casinò with an accent.

One of the first known casinos was established in Venice around 1638. During the 19th century, the term "casino" came to include other public buildings where pleasurable activities, including gambling, and sports took place. An example of this type of building is the Newport Casino in Newport, Rhode Island.

Not all casinos were used for gaming. The Copenhagen Casino was a theatre, known for the use made of its hall for mass public meetings during the 1848 Revolution which made Denmark a constitutional monarchy. Until 1937 it was a well-known Danish theatre. The Hanko Casino located in Hanko, Finland - one of that town's most conspicuous landmarks - was never used for gambling. Rather, it was a banquet hall for the Russian nobility which frequented this spa resort in the late 1800s, and is presently used as a restaurant. The so-called "Casino", a famous landmark overlooking Avalon Harbor on Catalina Island, has never been used for traditional games of chance, which were already outlawed in California by the time it was built.

In most jurisdictions worldwide, gambling is limited to persons over the age of license (18 or 21 years of age in most of the United States and 16 to 21 in most other countries where casinos are permitted).

Customers gamble by playing slot machines or other games of chance (e.g., craps, roulette, baccarat) and some skill (e.g., blackjack, poker) (for more see casino games). Games usually 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 often give out free items, known as comps to people who are gambling. Often, in most casinos, the more money a player uses the more benefits or comps the player get. Comps are determined on a formula set by the casino based on the player's average bet x the number of hours of play x the percentage that the casino will win on the player. Whether the player wins or loses does not matter; it is solely based on the formula. Comps can range in anything from free drinks during play to penthouse suites, free airfare, limo service, and free food.

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.

Gaming law can be described as the set of rules and regulations that apply to the gaming or gambling industry. Gaming law is not exactly a branch of law in the traditional sense but rather a transversal gathering of a range of legal topics related to gaming which encompasses matters normally included in various branches of law, including constitutional law, administrative law, tax law, company law, contract law and criminal law.

In the United States, illegal gambling is a Federal crime if done as a business. However, each of the United States has its own laws regarding the regulation or prohibition of gambling.
