A casino is a gambling establishment that offers several types of games of chance. These games are usually played against the house (the casino itself), as opposed to against other players. There are three general categories of casino games: gaming machines, table games and random number games. Gaming machines include slot machines and video poker, while table games include blackjack and craps. Random number games are based on the selection of random numbers by a computerized system.

Regardless of the game, casino patrons expect to win, at least sometimes. This is why casinos regularly offer high rollers extravagant inducements such as free spectacular entertainment, transportation and elegant living quarters. Even smaller bettors can receive reduced-fare transportation and other bonuses.

Although the precise origin of gambling is unknown, it appears in most societies throughout history. It is believed that ancient Mesopotamia, Greece, Rome and Elizabethan England all had some form of gambling. Today, casino gambling is legal in most states and is a major source of revenue for many countries.

There are a variety of casino types, depending on the local population and culture. For example, the casinos of Monte Carlo attract some of the world’s wealthiest people, while those in Las Vegas have become famous for their glitz and glamour. In the United States, land-based casinos are found in most states and many are located near large cities such as New York. New York City alone has 12 popular land-based casinos and 15 tribal casinos within striking distance.
