A casino is a gambling establishment where people gamble on games of chance or skill, such as poker and blackjack. A casino may also have other attractions, such as restaurants and bars. Some casinos are located in luxurious hotels, while others stand alone. The Bellagio, in Las Vegas, is a famous example of a casino that features world-class entertainment and accommodations.
A casino has to manage money and security concerns as well as its gambling operation. Its security personnel must watch over each area of the casino and be alert to any suspicious activity. Pit bosses and table managers oversee the tables, looking for blatant cheating like palming or marking cards. They must also keep an eye on the money coming in and out of a table game, so they can report any big wins to higher ups.
Casinos have to make sure they are making enough money to pay their employees and cover overhead costs. They have built-in advantages that ensure this, known as the house edge. High rollers, those who bet a lot of money, are a major source of casino profit. They are given special inducements to play in rooms separate from the main floor, including free spectacular entertainment and luxury suites. Lower bettors are rewarded with reduced-fare transportation, food and drink while they gamble and other things that encourage them to return to the casino again. This is called comping. It is one of the ways that casinos try to increase their gross profits.
