A casino is a building or room where people can gamble. Casinos are also known as gaming houses or simply gambling establishments. They may be standalone buildings or part of larger complexes that include hotels, restaurants, retail shopping, and other tourist attractions. Casinos often have security measures such as closed circuit television and other surveillance systems to prevent cheating.
In the United States, casinos are most associated with Las Vegas and Atlantic City. However, they can be found in many other cities and towns. Several state governments regulate and tax casino gambling. Some of the profits are used for public services and infrastructure. Casinos can also generate significant revenue for the owners, investors and Native American tribes that operate them. However, studies show that the impact of casino gambling on a local economy is mixed. Despite the fact that casinos bring in billions of dollars to their home communities, the cost of treating problem gambling and lost productivity due to compulsive gambling can offset any economic benefits.
In addition to a variety of table and slot machines, many casinos feature entertainment events such as concerts and stand-up comedy. Many offer dining options and nightlife as well. Guests at casino resorts can enjoy world-class cuisine and luxury accommodations. In modern times, casinos have dramatically increased the use of technology to enhance security and monitor guest activity. For example, in some casinos, betting chips with built-in microcircuitry interact electronically with the games; roulette wheels are monitored electronically to discover any statistical deviations from their expected results; and video cameras can be used to verify player identity at card tables or to record game play.
