A casino is a place where people gamble by playing games of chance. Some of these games have an element of skill, such as poker or roulette, but most depend entirely on luck. The casino earns money by taking a percentage of each wager, called the house edge. Casinos are a major source of income for many governments and have been a popular tourist destination since the 19th century.
The 21st-century casino is more than a gambling hall: it offers hotels, restaurants, non-gambling games, bars, swimming pools and spas. Its design is often elaborate and reflects the cultural heritage of its location. For example, in Macau, a new casino named the Grand Lisboa pays tribute to Portuguese rule over the region by echoing the design of Lisbon’s landmark church.
Local economies are boosted when large numbers of visitors flock to casinos. The money they spend in dining, entertainment and hotel rooms is re-invested in the economy. In addition, the presence of the casino draws attention from the media, which stimulates interest in the area and encourages more people to visit.
Something about gambling (probably the large amounts of money involved) seems to inspire cheating, theft and scams. Casinos invest a great deal of time, energy and money on security systems. Many have high-tech eye-in-the-sky cameras that monitor every table, window and doorway, and can be focused on suspicious patrons by security workers in a room filled with banks of monitors.
