A casino is an establishment for certain types of gambling. It is also a place for entertainment, socializing, eating, and drinking. In its modern form, a casino is usually integrated into a resort or hotel, and may offer a wide variety of games and entertainment. Casinos are commonly located in the United States, but they also exist in other places around the world.

When most people think of a casino, they picture one of the megaresorts in Las Vegas, a glittering, flashy entertainment complex complete with lighted fountains and giant casinos filled with blackjack and roulette tables. In fact, the term casino actually refers to an establishment that offers a variety of gambling activities, including slot machines, table games, and poker.

Casinos are in the business of making money, and successful ones rake in billions every year for owners, investors, and local, state and tribal governments. While musical shows, lighted fountains and shopping centers help lure in the crowds, the vast majority of revenue in a casino comes from games of chance. Slot machines, blackjack, roulette, baccarat, craps and keno provide the thrills that attract millions of tourists to Las Vegas and other casino destinations each year.

Casinos have a strong focus on customer service and offer perks designed to encourage gamblers to spend more than they intend to. These perks, called comps, are often free meals, drinks, rooms and show tickets. Many casinos have card programs that tally player points for frequent visitors, and some even offer airline tickets or limo service to top players.
