A casino, also known as a gambling house or a gaming hall, is an establishment for certain types of gambling. Modern casinos often incorporate entertainment facilities such as restaurants, hotels, and even shopping malls in addition to their traditional gambling operations. Some cities are well known for having casinos, such as Monte Carlo in Monaco, Atlantic City in New Jersey, and Chicago in the United States.

The term casino can refer to a number of different types of gambling establishments, including those that offer poker, blackjack, roulette, and slots. In general, casino games involve competing against the house or a dealer, with some requiring skill and strategy while others depend primarily on luck. A casino may earn a profit by taking a percentage of each wager or charging an hourly fee for the use of its tables and other equipment.

In the United States, the most popular type of casino is a land-based one. In recent years, the number of such establishments has increased significantly. Most of them feature a wide variety of electronic games, such as slot machines and video poker. Some of them offer more sophisticated versions of classic table games, such as baccarat, chemin de fer, and blackjack. A few feature table games that are unique to Far Eastern culture, such as sic bo (which became popular in the 1990s and is now found in many American casinos), fan-tan, and pai gow.
