A casino is an establishment for certain types of gambling. Casinos are often combined with hotels, restaurants, retail shopping or other tourist attractions. In the United States, casinos are regulated by state and local laws. The industry is sensitive to problems associated with problem gambling, and some casinos have introduced initiatives to prevent and treat gambling addiction.

The largest casinos in cities such as Las Vegas and Atlantic City have thousands of slots along with hundreds of table games. The majority of these games are card games such as blackjack, baccarat and roulette. Some casino players also like to play dice games such as craps or keno. The big casinos even have discreet rooms where high rollers can have quiet sessions with only a select few other customers.

Gaming machines and table games typically use chips with built-in microcircuitry to track player wagers minute by minute and automatically report any suspicious activity to the casino’s security staff. In addition, the spinning wheels of roulette and other table games are regularly monitored electronically to discover any statistical deviations from their expected values. This information is used to identify the need for maintenance or to warn gamblers about a possible discrepancy in their game results.

Casinos have become more than just gambling houses, and many now serve as entertainment destinations for visitors from all over the world. Some of them are located in famous architectural and historic buildings, while others are set in luxury resorts with top-notch restaurants and other amenities. Some casinos are located on American Indian reservations, where they may be exempt from state gambling laws.
