Casino is an establishment for gambling games, and it includes a wide variety of table and machine games such as poker, slots, blackjack, roulette, craps, baccarat, and more. These types of games generate billions of dollars each year for the private corporations, investors and Native American tribes that operate casinos. These profits are offset, however, by the costs of compulsive gambling and lost productivity associated with problem gamblers.

A casino is not only a place for gambling, but also offers dining, entertainment and retail shops. It is common for casino to be combined with hotels and resorts. They can also be found at racetracks in the form of racinos and on cruise ships.

Modern casinos make heavy use of technology for security and surveillance purposes. Computer systems track betting patterns, and video cameras record the action on the casino floor to identify possible criminal behavior. Casinos are also experimenting with new technologies that allow them to monitor players’ facial expressions and body language for signs of deception.

The typical casino patron is a forty-six-year-old female from a household with above-average income. According to a 2005 study by Roper Reports GfK NOP and the U.S. Gaming Panel, people who are addicted to gambling generate a disproportionate share of casino profits—about five percent. This money is derived from the local economy, but critics argue that it shifts spending away from other forms of entertainment and undermines community morale.

In the twenty-first century, some casinos have become choosier about who they allow to gamble and focus on high rollers, those who spend the most money. These individuals are usually treated to special rooms and suites, as well as a range of other perks.
