A casino, also known as a gambling house, is a place where people can gamble on games of chance or skill. Modern casinos often combine this with other entertainment such as restaurants, hotels and shopping to form a resort or casino complex. Some of the larger casino complexes in cities such as Las Vegas and Atlantic City feature thousands of slot machines along with a wide variety of table games like blackjack, roulette, craps, baccarat and poker. The casino industry is one of the most profitable in the world. It is estimated that casinos bring in more than $100 billion a year in revenue.
Gambling has long been a popular pastime. Its history dates back to the earliest civilizations, with primitive protodice (cut knuckle bones) and even carved six-sided dice found in prehistoric archaeological sites. Modern casinos evolved from the late 16th century gambling craze that began in Venice, Italy. The first official government-sanctioned gambling house was the Ridotto, a four-story venue that offered primitive card games, drinking and dining for rich patrons [Source: Schwartz].
Modern casinos are typically designed with security in mind. They have a combination of physical and specialized surveillance departments. The former consists of a guard force that patrols the casino, responding to calls for assistance or reports of suspicious or criminal activity. The latter is comprised of a team that operates the casino’s closed circuit television system, commonly referred to as the eye in the sky. The casino security teams work closely together to prevent crime from occurring on the property.
Most modern casinos offer a wide range of card and table games. The most common table games are blackjack, baccarat, and poker. These games, along with slots and video poker, make up the vast majority of a casino’s income. Table games such as craps and keno, while less popular, can also be found in many casinos. In addition, some casinos may offer a smaller selection of traditional Far Eastern games such as sic bo and fan-tan.
In the United States, casino gaming is regulated at the state level. While there are some differences between state laws, most have similar regulations. All states except Nevada have legalized some form of casino gambling. The Nevada law allows for both commercial and tribal casinos. The commercial casinos are operated by private companies, while the tribal casinos are operated by the various governments of the respective reservations.
Although modern casinos use a variety of luxury amenities to attract customers, the most important part of any casino is its games of chance. These games have mathematically determined odds that give the house a permanent advantage over the players, which is called the house edge. Because of this, it is extremely rare for a casino to lose money on its games. In order to offset this advantage, casinos offer generous incentives to big bettors. These may include free spectacular shows, rooms, transportation and other luxurious amenities. They may also offer reduced-fare transportation or hotel rooms to lesser bettors.
