A casino is a place where gamblers risk money in a safe environment. They can eat, watch live shows or closed-circuit broadcasts and take in the sights and sounds of this fun activity. The seedy backroom gambling parlors of the past are replaced by large casinos that offer an experience to people of all ages and backgrounds who enjoy playing games, winning or losing, and interacting with each other in a fun, exciting setting. Casinos also employ security guards, monitor parking lots and take precautions against the crime that plagues many other areas of town.
Casinos are designed to attract gamblers and keep them playing as long as possible. They do this by creating intimate spaces with a labyrinth-like walkways of enticing machines that are arranged to appeal to the senses of sight, touch and sound. Slot machine noises are electronically tuned to the musical key of C, which is pleasing to human ears, and more than 15,000 miles (24,100 km) of neon tubing lights casinos along the Las Vegas Strip.
The casinos rely on customers to generate revenue, and they try to get as many of them in the door as possible by offering free food, drinks and show tickets as well as comps, which are goods or services that the casino gives away to “good” players. These perks are designed to encourage gamblers to spend more and they can even include free hotel rooms, meals and limo service for those who play the most.
