A casino is a facility for certain types of gambling. Modern casinos often combine gambling facilities with hotels, restaurants, retail shopping, and other tourist attractions. They may offer a huge variety of games, including poker, slot machines, and more. Often, casinos also host live entertainment events. In the United States, Las Vegas is considered the center of casino gaming.

A casino makes money by charging patrons for the right to play its games. Typically, each game has a built in advantage for the casino. This edge can be small (less than two percent), but it adds up over the millions of bets placed each year. Casinos also make money from a vig, or rake, on the profits of slot machines and video poker machines.

Because the large amounts of cash handled within a casino make it susceptible to theft by both patrons and employees, security is a high priority in most casinos. Casinos employ a variety of measures to prevent theft, including cameras located throughout the facility. In addition, many casino games have specific rules that must be followed to prevent cheating and stealing.

Gambling has been part of human culture since ancient times, and casinos are one of the most popular forms of recreation today. Modern casinos are designed like an indoor amusement park for adults, offering a variety of games, food, drinks, and entertainment. Some even feature hotels, pools, spas, and live entertainment. They are a favorite destination for vacationers and locals alike.
