A casino is a facility for certain types of gambling. Unlike your grandmother’s weekend bus trips to the nearest bingo hall, modern casinos are largely places where people gamble with real money. Slot machines, black jack roulette, craps and more are the main sources of the billions in profits raked in by casinos every year. Casinos can be found around the world, and are a major source of income for some countries.
In the United States, Nevada and Atlantic City are the top casino destinations, but many smaller cities have also added them to their local economies. In the 1980s, several American Indian reservations legalized gambling, allowing casinos to open on those grounds as well.
Casinos have a variety of security measures to protect patrons and staff. For example, some have catwalks in the ceiling above the gaming floor that allow surveillance personnel to look directly down through one-way glass at the activities on the tables and slots. Other security features include closed circuit TVs and electronic card readers on all entrance doors.
In addition to security, some casinos use a variety of tactics to keep gamblers happy and spending. Free food and drinks, for instance, are a staple. The use of chips instead of cash also helps prevent players from becoming concerned about how much they’re losing, and allows the casino to track player activity more easily. In addition, windows and chiming clocks are rare in casinos; this prevents players from realizing how long they’ve been gambling or how much money they’ve spent.
