A casino is a gambling establishment that allows patrons to place bets on games of chance and skill. The games often require strategic thinking, decision-making skills and a bit of luck to win. They can be played in massive resorts, racinos (casinos at racetracks), or even small card rooms in bars and restaurants. Regardless of where they are located, casinos pull in billions each year for their owners, investors and Native American tribes, and offer millions to bettors who enjoy the thrill of taking a chance.
In the United States alone, the 51 million people over 21 who visited a casino in 2002 generated revenues of $25.7 billion. In addition to the profits for the businesses, investors and tribal organizations, casinos also provide millions in tax revenue.
The most successful casinos are those that cater to high rollers, patrons who bet tens of thousands of dollars per hand or spin. These VIPs are pampered with free spectacular entertainment, limousine service, and elegant living quarters, and are often given the chance to gamble in private rooms away from the main floor.
Casinos are usually decorated in bright and sometimes gaudy colors, such as red, which is believed to cause players to lose track of time and increase their gambling habits. Many casinos do not have clocks in their buildings because they are a fire hazard, and the lighting is designed to mimic daylight to help patrons stay awake during long sessions of gambling.
