A casino is a facility for people to gamble. Casino games can be broadly divided into three categories: gaming machines, table games, and random number games. Gaming machines, such as slot machines and pachinko, are played by one or more players at a time and do not require the involvement of casino employees. Table games, such as blackjack and craps, involve a game of chance and are conducted by dealers or croupiers. Random number games use a computerized system to select numbers and are based on luck, rather than skill.

Throughout the world casinos can be found in a variety of locations. In the United States they can be found on Indian reservations that are exempt from state anti-gambling laws and in Atlantic City, where the gambling industry first developed. In the 1980s many American states began to change their gambling laws and allow casinos.

The largest casino in the world is located in Macau, China. It is called the Venetian, and it boasts a hotel with more than 3,000 rooms, a theater that can seat up to 4,000, a performance lake featuring a choreographed water show, and over 1,000 slot machines and tables.

Whether or not you like to gamble, there is no doubt that casinos are a fascinating place. Their grand design and massive size have captured the imagination of many a visitor. They also serve as a backdrop for a host of entertainment and have even been featured in films.
