Globally, over 100,000 units of discarded casino equipment are generated annually, containing large amounts of metals (steel, aluminum), electronic components (circuit boards, chips), and plastics. A specialized surveillance department operates the casino’s closed-circuit-television system, known in the industry as the eye in the sky. On the other hand, “gambling houses” or “gambling dens” are smaller, illicit gambling venues. The Marina Bay Sands is the second most expensive standalone casino in the world, at a price of US$6.8 billion, and is among the world’s ten most expensive buildings.<\/p>\n

Frequent replacement of gambling equipment exacerbates energy waste and also causes environmental problems. Additionally, 46.2% of the respondents believed that such activities contribute positively to Vietnam’s ability to attract investments. Furthermore, 47.4% of the participants expressed the view that engaging in rewarding recreational activities has a positive impact on job opportunities for residents. Based on revenue, Atlantic City, New Jersey, ranks second, and the Chicago region third. Macau also surpassed Las Vegas as the largest gambling market in the world. This started in Portuguese times, when Macau was popular with visitors from nearby Hong Kong, where gambling was more closely regulated.<\/p>\n

In addition to cameras and other technological measures, casinos also enforce security through rules of conduct and behavior; for example, players at card games are required to keep the cards they are holding in their hands visible at all times. Some casinos also have catwalks in the ceiling above the casino floor, which allow surveillance personnel to look directly down, through one way glass, on the activities at the tables and slot machines. In Vietnam, the term “casinos” encompasses gambling activities within the country. Machine-based gaming is only permitted in land-based casinos, restaurants, bars and gaming halls, and only subject to a licence. Video lottery machines (slot machines) have become one of the most popular forms of gambling in casinos.<\/p>\n
