A Casino, or gambling establishment, is a facility where individuals can wager money on various games of chance. Many states have legalized casinos, but the largest concentration is in Las Vegas and Atlantic City. Some casinos are built as standalone buildings, while others are located within hotels or resorts. In some cases, the casino acts as an entertainment venue in addition to a gambling hall.

During the second half of the 20th century, casino gambling expanded rapidly across the United States and throughout the world. During this time, casinos became more sophisticated in their operations and security measures. Security cameras, for example, are now standard in most casinos. These cameras are used to monitor the movements of patrons and staff to prevent cheating or theft.

Most casinos also employ a variety of other methods to protect their patrons and property. For example, some casinos have catwalks in the ceiling that allow security personnel to look down through one-way glass on the activities of table players and slot machine operators. Some casinos have also installed electronic sensors that can detect unusual vibrations or sounds coming from the machines.

Bringing the glitz and glamour of Tinseltown to central Pennsylvania is Hollywood Casino at Grantville. The casino features slots, table games and poker, as well as live horse racing on Wednesday through Saturday. Guests can also try their luck at the 5,000-seat Hollywood on the Roof stage and dine at five different restaurants.
