A casino is a public place where games of chance are played. Although most casinos add a host of luxuries to the mix to attract patrons, such as restaurants, stage shows and dramatic scenery, a casino is fundamentally a gambling establishment.
Most casino games are based on chance, but there are some that require skill. Most games have a mathematically determined house advantage, and it is very rare for a casino to lose money on any given day. This house edge can be found in most table and card games, as well as some video poker machines.
Security in a casino is important, and there are a variety of measures to keep the premises safe. The most common method is to monitor patrons closely using cameras. These are usually positioned throughout the casino, and can be adjusted to focus on specific patrons at a particular game. In addition to the cameras, a security team watches over the entire casino floor from a room filled with banks of security monitors. Casinos also employ dealers who are trained to look for any suspicious behavior, such as palming or marking cards. In addition, the dealers are also expected to keep their hands visible at all times. Despite these measures, cheating is very prevalent in casinos.
