A casino is a place where people can play games of chance or skill and win money. The term usually refers to a large building that houses many gambling tables, but it can also refer to less elaborate places that house gambling activities, such as barrooms and card rooms. Successful casinos bring in billions of dollars each year for the companies, investors and Native American tribes that run them. They also generate millions of dollars in taxes and fees for local governments and other organizations.
The earliest casinos were located in Nevada, but they soon spread throughout the country and the world as state legislatures relaxed laws limiting gambling. By the 1980s, Atlantic City became a major casino destination and Native American casinos proliferated nationwide as states legalized them on reservations. In the 1990s, casinos began appearing on riverboats and in some cases at racetracks, which are called racinos.
Casinos employ sophisticated security measures to prevent cheating and other illegal activities. Some of these include video cameras that watch every table, window and doorway, and that can be adjusted by security workers to focus on suspicious patrons. Table managers and pit bosses keep a close eye on the tables they oversee, watching for signs of crooked dealing or dice-rolling; and each slot machine has a higher-up that monitors its statistical deviations from expected outcomes.
A typical casino patron is a forty-six-year-old woman from a household with above-average income, and she spends most of her time playing slot machines. Despite the large profits that casinos generate, most of them are losing propositions for their owners and investors, and many have a negative effect on local economies by stealing spending from other forms of entertainment.
