A Casino is a place where people can gamble by playing games of chance. Some casinos also have non-gambling attractions like restaurants, hotels, pools and spas. In the United States, there are more than 1,000 casinos and many of them offer top-notch entertainment. Some casinos are so big that they are more than just gaming facilities; they are complete resorts.
Most casinos have a large number of games that customers can play. These games fall into three general categories: gaming machines, table games and random number games. Gaming machines, such as slot machines, are played by one customer at a time and do not require the involvement of casino employees to play. Table games, such as blackjack and craps, involve one or more players competing against the house, with the game being conducted by casino employees called croupiers or dealers. Random number games are based on the selection of random numbers, either by a computer or by other means.
Modern casinos have a strong focus on security. Most have a dedicated physical security force and a specialized surveillance department. These departments work closely together and are able to respond quickly to calls for assistance or reports of suspicious activity. In addition, a growing number of casinos are taking gambling addiction seriously and are instituting programs to help problem gamblers. These programs often include a self-exclusion option and prominently display brochures for Gamblers Anonymous and other treatment options near ATM machines and pay phones.
