What Is a Casino?

A casino is a gambling establishment where people play games of chance, or some that involve skill, for money. The games can be played on a table, such as poker and blackjack, or on a mechanical device such as a roulette wheel or traditional slot machines. The games are usually noisy and crowded, with lights, music and excitement designed to stimulate gamblers. Many casinos offer food and beverages, often for free to players.

In the United States, the number of people who visit casinos has been increasing steadily since their legalization in the late nineteenth century. In 2002, the American Gaming Association estimated that 51 million people—a quarter of the population over age 21—visited casinos domestically and internationally.

While some casino patrons enjoy the atmosphere, others become addicted to the gambling activity and find it difficult to control their spending or stop. Compulsive gambling creates a variety of psychological problems and has a negative impact on the mental health of those affected by it. The cost of treating gambling addictions often outweighs any economic benefits a casino might bring to its community.

Most casino profits come from high bettors, known as “high rollers.” These gamblers spend large amounts of money and are offered special services such as free luxury suites and limousine service. Some casinos have separate rooms for high-stakes gamblers where the rules and payouts are more generous than in the main casino floor. Other casinos have a more general policy of rewarding frequent patrons with free goods and services, such as hotel rooms, show tickets or meals.
