Casinos are entertainment centers that use games of chance to attract customers. They often feature musical shows, shopping centers and elaborate themes. While many people think of Las Vegas and other gambling meccas when they think of casinos, they actually exist in most countries in the world. In this article, we take a look at the history of casinos, how they make money and the games that they offer.
Gambling in some form has been a part of human civilization for millennia. Archaeological evidence of dice games dates back to 2300 BC, while a game that would later become poker was first recorded in the 1400s. In modern times, casinos have grown to become an international phenomenon. The first commercial casinos appeared in Nevada, but they soon spread to other states that recognized their potential as a tourist attraction. Casinos can also be found on American Indian reservations, which are exempt from state antigambling laws.
Despite their extravagant appearances, casinos are mostly business operations that make billions of dollars in profits each year. Although some of this revenue comes from entertainment and other non-gambling activities, the vast majority is generated by games such as slot machines, blackjack, roulette, craps, keno and baccarat. While glitzy architectural designs, lighted fountains and shopping centers may help draw in visitors, casinos would not exist without these games of chance.
There are three general categories of casino games: gaming machines, table games and random number games. Gaming machines, such as slot machines, are played by one person at a time and do not require the involvement of casino employees. Table games, such as blackjack or baccarat, involve one or more players competing against the house and are conducted by casino employees known as croupiers. Random number games are based on the selection of random numbers, either by a computerized random number generator or from other sources such as television sets or lottery tickets.
Most casino games have a mathematically determined advantage for the house, which is called the house edge. However, in the case of a game with an element of skill, such as blackjack, the house edge is slightly less than in other games. In order to remain competitive, casinos offer large bettors free spectacular entertainment and other inducements such as limo service and airline tickets. In addition to this, casinos rely on the revenue from table games and, since the 1980s, video poker and other electronic machine-based games.
In order to prevent cheating and theft, both by patrons and staff, casinos have a variety of security measures in place. The most obvious are the numerous cameras that monitor every aspect of the casino. These are located throughout the building and can be adjusted to focus on suspicious patrons by security workers in a separate room filled with bank of surveillance monitors. In addition to these technological devices, security personnel have a set of rules that they must enforce. This includes the need for all players to keep their hands visible at all times while playing card games and not to touch each other or any of the cards in the decks.
