A casino, or gambling house, is a facility for certain types of gambling. Modern casinos are generally combined with hotels, restaurants, retail shopping and other tourist attractions. Some casinos feature live entertainment such as shows or concerts. Others offer video poker and a variety of table games. In some states, casinos are operated on Native American reservations. Casinos are also found on cruise ships and in foreign countries.

While gambling has existed in some form since ancient times, the casino as a gathering place for a variety of gambling activities did not develop until the 16th century. This was during a gambling craze in Europe, when Italian aristocrats held parties at places called ridotti [Source: Schwartz].

Many factors make the casino experience different from other forms of gaming. Unlike lotteries, which are often conducted on private property, players at the casino interact with each other or are surrounded by other gamblers in table games like blackjack or craps. There is usually loud music and bright lights to create an exciting atmosphere. Alcoholic drinks are readily available and waitresses rove the tables offering free drinks. Some casinos also reward high bettors with free hotel rooms, meals and tickets to shows.

The most popular casino games in the United States are roulette, blackjack and slots. Other games include craps, baccarat and keno. These games provide the billions of dollars in profits raked in by casinos each year. But there is a dark side to the business that has contributed to its reputation as a haven for organized crime and vice.
