Casino refers to a gambling establishment that offers games of chance. They can range from massive resorts and hotels to small card rooms. In the United States, they are usually operated by private companies or Native American tribes and are licensed by state gaming control boards. They generate billions of dollars each year for the companies, investors, and owners who operate them. In addition, they pay millions in taxes to state and local governments.

Because of the enormous sums involved in casino gambling, security is an important issue. In addition to the obvious physical protection provided by a casino’s security forces, casinos use surveillance systems to monitor patron activity and prevent crime. Despite these measures, both patrons and staff may try to cheat or steal, either in collusion or independently. For this reason, modern casinos have a specialized surveillance department as well as a physical security force.

Many casinos offer a variety of games, including poker, blackjack, and roulette. Some have additional perks like live entertainment, a spa, and restaurants. Some even offer a sports book. In addition to these amenities, many casinos also have a loyalty program that rewards gamblers for their play. These programs are similar to airline frequent-flyer programs and give players the opportunity to earn coupons for free slot play, meals, drinks, or shows.

High rollers, who are gamblers who spend a lot of money, are often rewarded with special perks such as free luxury suites and lavish personal attention. For smaller wins, players can choose to receive regular payouts or a lump sum. If they choose to receive a lump sum, they must pay tax on the winnings.
