A casino is a gambling establishment that offers a variety of games of chance and accepts bets from patrons. It may also offer stage shows and other entertainment, as well as restaurants and free drinks. Historically, casinos have been associated with organized crime and vice. However, as American gaming laws changed in the 1980s and 1990s, legitimate businessmen stepped in to buy out mobsters and run casinos without mob interference. In some cases, they have even tried to dispel the casino’s seamy reputation by adding luxuries like spas and high-end dining options.

In addition to the usual table and slot machines, casino patrons can bet on sports events, horse races, bingo and lottery games. Most casinos have a full complement of these games, plus many offer high-stakes table game action, including poker.

The casino’s edge on each bet is small, less than two percent, but the millions of bets placed by patrons earn the casino enough money to finance dazzling hotels, fountains, pyramids and towers, as well as an extensive inventory of expensive art. The casino also earns money from a commission on games that require some skill, such as blackjack and baccarat.

Because of the large amounts of money handled within a casino, employees and patrons are often tempted to cheat or steal. To prevent this, the casino employs various security measures. These range from a high-tech “eye in the sky” to surveillance cameras that monitor each and every game.
