A casino is a place where people pay to play games of chance or skill. Some casinos are large entertainment complexes, replete with restaurants, hotels, and other amenities. Others are smaller, gambling-only establishments. Some are built in scenic locales, such as Venice’s Grand Canal and Monaco’s Casino de Monte Carlo.

Gambling has been an important part of human society for millennia. Evidence of gambling has been found in China (2300 BC), Rome (500 AD), and Greece (8th century). Casinos appeared in Europe in the 1600s, including the first legal gaming house in London, England. Many state governments prohibit casinos, while others endorse them or regulate them. In America, the first legal casino opened in Atlantic City, New Jersey, in 1978. During the 1980s and ’90s, casinos also began to appear on American Indian reservations, outside state jurisdiction.

In addition to offering a variety of gambling opportunities, casinos focus on customer service. They often offer free food, drinks, and hotel rooms to regular gamblers. The perks are called comps. Some casinos also sponsor a variety of public entertainment events, such as concerts and sporting/racing events.

Casino patrons are usually young, well-educated adults with above-average incomes and a taste for glamour. In 2005, Harrah’s Entertainment surveyed 2,000 people who admitted to being casino gamblers. It found that the most popular game was slot machines, followed by blackjack and poker. The least-popular games were keno, bingo, and sports/racing gambling. The company also analyzed demographic data and found that the typical casino gambler was a forty-six-year-old female from a household with above-average income.
