A Casino is a building that houses a variety of games of chance. These include poker, roulette, blackjack, craps, baccarat and video poker. The house has a mathematically determined advantage over the customers, called the house edge.
Various forms of security are used at casinos to ensure the safety and integrity of the gaming process. For example, dealers are trained to spot cheating such as palming or marking cards or dice; they also keep an eye out for betting patterns that could indicate stealing from other patrons.
Another form of security is technology. Casinos routinely use video cameras and computers to monitor game activities. These cameras and computers track the betting patterns of the players at the table, and alert them to any changes in their expected winnings or losses.
Some casinos have catwalks over the floor that allow surveillance personnel to look down, through one-way glass, on the players at the tables and slot machines. These catwalks can be extremely effective, and are used to keep an eye on any suspicious activity or to catch gamblers who cheat at their games.
The most important and common casino games are slots and table games such as roulette, baccarat and blackjack. These games are very popular with players and can be found at most casinos, including some of the largest ones in Atlantic City and Las Vegas.
Aside from gambling, some casinos offer other leisurely experiences that can be enjoyed while on the premises. These can range from exclusive performances by music stars, circus troops and stand-up comedians to luxurious dinners at Michelin star restaurants.
