What Is a Casino?

A casino (plural casinos) is a gambling establishment offering table games such as blackjack, roulette, and poker. It also offers slot machines and other games of chance, such as video lottery terminals. Casinos are operated by government-licensed operators and are typically located in exotic locales, such as Las Vegas, Monaco, and Singapore. Often, the facilities are opulently outfitted with restaurants, hotels, spas, and entertainment.

A player’s success at a casino game depends partly on luck, but casinos have many other strategies to encourage patrons to gamble. They offer free spectacular entertainment, reduced-fare transportation and lodging, upscale living quarters, and complimentary drinks and cigarettes while gambling. Moreover, they employ many staff members to oversee security.

Casinos earn most of their profits by charging a small percentage of every bet placed on the tables or on electronic games. This charge, known as the house edge or vigorish, can be lower than two percent, but over millions of bets it adds up to a significant revenue stream for the casinos.

Something about gambling, however, seems to inspire people to cheat or steal their way into a jackpot. As a result, casinos spend enormous amounts of time, money and energy on security.

The casino industry has evolved in parallel with the popularity of the games it houses. The first casinos were simple betting shops that accepted bets on horse races and sporting events. Later, they began to offer more sophisticated games such as baccarat, chemin de fer, and blackjack. Casinos have also come to include other types of games, such as pai gow and Caribbean stud poker.

Modern casino technology enables operators to monitor games more closely than ever before. For instance, in a new system called “chip tracking,” a casino’s betting chips have built-in microcircuitry that interacts with a computer program to enable the operator to oversee how much is wagered minute by minute and to warn if a discrepancy occurs. Similarly, electronic systems on roulette wheels allow casinos to quickly discover any statistical deviation from expected results.

The modern casino has become a complex business with a storied history. During the 1920s, organized crime figures provided the capital to establish Las Vegas casinos, which earned a reputation for vice and sex. As mob involvement in casinos grew, legitimate businesses were reluctant to get involved with the industry. But the mobsters weren’t bothered by gambling’s seamy image, and they became personally involved with their casinos, taking sole or partial ownership of them and influencing decisions regarding security, games, and other aspects of operation.
