The word casino is derived from the Portuguese word for “house.” In terms of gaming, casinos are establishments where players can place bets on games of chance or with some skill. Some casinos are also known for their live entertainment and fine dining restaurants. Some casinos are combined with hotels or resorts, and some are located on cruise ships. The majority of casinos are located in Nevada.
Casinos earn their money from a variety of sources, but the most important are patrons’ bets. Most casino games have mathematically determined odds that guarantee the house a profit, usually through a percentage of total bets or by charging a hourly fee. These amounts are typically calculated by expert mathematicians or computer programmers who specialize in gaming analysis.
Most casinos offer several different types of games, including craps, roulette, blackjack, baccarat and video poker. Some casinos even feature traditional Far Eastern games such as sic bo (which has since spread to European and American casinos), fan-tan, pai gow and banca francesa.
Something about gambling (perhaps the large sums of cash involved) encourages people to cheat and steal, either in collusion or independently. For this reason, casinos spend a great deal of time and money on security. Cameras are the most obvious security measure, but they are augmented by rules of behavior and other forms of surveillance.
In addition, most casinos make a portion of their profits from the sale of food and drinks, and they often offer other freebies to attract patrons. Whether a casino is a major entertainment complex or a small local venue, it provides jobs and economic growth for the community. A study by the American Gaming Association found that communities with casinos experience higher employment in restaurant, retail, and other business sectors than those without.
