What Is a Casino?

A casino is a facility wherein people gamble by playing games of chance, in some cases with an element of skill. Most casinos have mathematically determined odds that ensure the house has an advantage over the players; this advantage is commonly known as the house edge. In some casino games, such as poker and video poker, the house takes a rake or commission on wagers; this is also known as the pay-out percentage.

Most modern casinos have extensive security measures in place. These include physical security forces and a specialized department that oversees the casino’s closed circuit television system. In addition, many casinos have catwalks that allow security personnel to look directly down, through one way glass, on the activities at tables and machines.

Casinos are often located in cities or towns that are famous for gambling. Las Vegas, Nevada, is the most famous and best known example of this type of city, but there are also several in Atlantic City, New Jersey; Chicago, Illinois; and other cities. In addition to the gambling facilities, casinos often have restaurants, hotels, and entertainment venues.

Casinos are regulated by the state in which they are located. Some states have laws governing how much money casinos can make, and others limit the number of slot machines or table games that they may have. Some states have laws requiring casinos to offer certain minimum pay-outs, and some states prohibit casinos from paying out winnings to minors.
