A casino, also known as a gambling house or a gaming hall, is an establishment for certain types of gambling. It may be combined with hotels, restaurants, retail shops or cruise ships. Often, it is located in a scenic locale and is designed to attract gamblers. It may feature one or more slot machines, table games, and other gambling activities. A casino may also offer non-gambling attractions such as shows, concerts and sporting events. In some countries, casinos are licensed and regulated by government agencies.

Most casinos are built around a central gaming area featuring a number of tables and slot machines. Usually, the casino floor is lined with windows to allow patrons to view the action and sometimes people-watch. To keep tabs on the games, many casinos install catwalks that run above the casino floor and are angled so security personnel can look down at the table games and slot machines through one-way glass.

The gambling industry is a major employer and contributes to local economies in many ways. It is estimated that it provides employment to more than two million people worldwide. In addition, it is an important source of tax revenue for some states. However, the industry is prone to gambling addiction and has been linked to a host of other problems, including crime, bankruptcy, and family discord. In addition, casinos can be a serious drain on local housing markets and hurt property values in surrounding neighborhoods.

Casinos are often designed to be stimulating environments. They use bright colors, gaudy wall coverings, and sometimes loud music to attract gamblers and keep them playing. Some casinos even have scents that are designed to stimulate the senses of the players. Red is a popular color for the floors and walls because it is believed to make gamblers lose track of time.

Gambling is a very addictive activity and most gamblers are not aware of how much they are spending. In fact, some gamblers will not stop until they have spent all their money. Because of this, casinos are able to give away lavish inducements to big bettors, such as free hotel rooms, discounted transportation, and buffets. These perks are designed to increase the amount of money that gamblers spend at the casino. It is estimated that the average casino patron is a forty-six-year-old female from a household with above-average income. The most frequent casino visitors are men and women over the age of fifty, who have more leisure time and discretionary spending money than younger adults. This demographic has contributed to the recent increase in casino visits. According to a survey conducted by Roper ASW and NFO WorldGroup for the American Casino Association in 2003, 30% of adults reported visiting a casino within the past twelve months. This figure was up substantially from the 20% of Americans who visited a casino in 1989. The survey was based on face-to-face interviews with 2,000 American adults and a questionnaire mailed to a panel of 100,000.
