A casino is an establishment that offers chances for gamblers to win money through games of chance and in some cases with a slight element of skill. Slot machines, blackjack, roulette and craps generate the billions of dollars in profits raked in by casinos every year. Other attractions may include musical shows, lighted fountains and lavish hotels, but gambling is what draws people to casinos.
Gambling is illegal in many areas of the United States, but Nevada and Atlantic City are home to the largest concentration of casinos in the country. Native American gaming has also become a growing industry in some states. A casino is a business, and like any other business it must be run responsibly. This means keeping a close eye on the odds of each game, the amount of money that can be lost and the percentage of players who walk away with winnings.
Casinos must have a high level of security to prevent cheating, stealing and collusion by patrons and employees. Security cameras located throughout the facility help monitor activities. Dedicated personnel keep an eye on each table game, making sure that dealers aren’t using sleight-of-hand to mark cards or switch dice, for example. Pit bosses and table managers watch over the tables with a more sweeping view, noting betting patterns that may indicate cheating.
Some casinos have specialized departments to research and calculate the house edge and variance of their games. These experts are called gaming mathematicians and analysts. They use mathematical calculations and computer programs to determine the odds that a player faces in a given game, how much money a casino expects to make from that game and how big of a risk is involved.
Casinos are also required to have a certain level of customer service in order to attract and retain customers. For this reason, they often reward “good” gamblers with free hotel rooms, dinners, tickets to shows and even airline tickets. These incentives are called comps. During the 1970s, Las Vegas casinos used comps to fill hotel rooms and encourage gamblers to spend as much time as possible gambling.
While casino comps have lost some of their luster in recent years, they remain an effective way to lure customers and boost profits. According to a 2005 study by Roper Reports GfK NOP and the U.S. Gaming Panel by TNS, the average casino patron is a forty-six-year-old female from a household with above-average income. This age group has the most available leisure time and discretionary income to spend on gambling. A casino’s interior design is also geared to attract this demographic by using bright colors and gaudy designs. Some casinos even have special carpeting and wall coverings that are designed to be reminiscent of the sky or desert. The color red is a popular choice, because it is thought to stimulate the brain and increase gambling activity. The casinos are also equipped with a wide range of audio and video systems to enhance the experience and make it more realistic.
