A casino is a place where people gamble. The gambling is usually done by playing games of chance. These include roulette, blackjack, and poker. Typically, the customer can bet only within the limit established by the casino. However, the casino may also offer other forms of gaming.
Slot machines are the economic mainstay of American casinos. There are also hundreds of different table games at the largest casinos. Usually, these are operated by a live croupier, but there are some wholly automated versions available.
Casino security is typically divided into physical and specialized surveillance departments. Casinos are equipped with a closed circuit television system. CCTV cameras are commonly used to monitor wagers. In addition, some casinos have catwalks above the floor for surveillance personnel to look down.
Some casinos even offer free drinks to customers. Sometimes, patrons can even be given free cigarettes. They also often offer extravagant inducements to the big bettors.
The specialized security forces at casinos have been quite effective at preventing crime. But even with this protection, some patrons are tempted to cheat.
One of the major reasons for the rise of casinos outside Las Vegas and Atlantic City is Native American gaming. Many modern casino resorts include dining and entertainment facilities, and some offer Michelin star restaurants.
Table games are a separate category from slot machines. Most are mathematically determined to give the casino an advantage over the player. This advantage is called the house edge.
