A casino is a gambling establishment where games of chance are played and winnings are derived from the result of those chances. Many casinos also offer dining, entertainment, and shopping. Traditionally, they are located in cities with legalized gambling or on reservations controlled by federal and state governments. However, since the late 1990s, some states have permitted non-resort casinos to be built in rural areas. Casinos are often combined with hotels, resorts, restaurants, retail shopping, and cruise ships.
There are over 1,000 casinos in the United States, although not every city has one. Some of the largest include Las Vegas, Atlantic City, and Reno. Some are operated by large hotel chains; others are standalone. Most casinos offer traditional casino games, including blackjack, roulette, and poker. Some casinos are specialized, featuring games such as Asian-style games like sic bo and fan-tan, or games specific to the local culture, such as two-up in Australia or banca francesa in Portugal.
Modern casinos use a combination of physical and specialized surveillance to prevent criminal activity. The former consists of regular patrols by security forces and the use of closed circuit television systems, or “eye in the sky”; the latter consists of sophisticated computer monitoring of game play that can detect anomalies in the patterns of bets or in the behavior of players. Casinos have also incorporated the use of microchips in betting chips, to monitor the exact amount wagered minute by minute, and electronic monitoring of roulette wheels, to discover any statistical deviation from expected results.
Casinos are a major source of employment for many people, and are important contributors to local economies. Despite this, they have been the subject of intense political controversy. Some critics argue that casinos promote gambling addiction and divert money from other forms of recreation; and that the costs of treating problem gamblers far exceed any profits generated by casino operations. Others point out that casinos are a significant source of revenue for tourism, and help revitalize historic districts in some urban areas.
Most of the world’s casinos are located in Nevada and other states that permit gambling, but there are also a number of casinos in Canada and elsewhere. Most casinos feature multiple gaming floors with hundreds of slot machines and table games. The Horseshoe Casino in Niagara Falls, for example, has 130 tables and upwards of 3000 slot machines, and provides stunning views of the world’s largest waterfall. In addition, the resort features luxury suites and rooms overlooking the falls. The most popular casino games are craps, poker, and blackjack. Those who prefer skill-based games may prefer video poker or baccarat.
