A casino, also known as a gambling house or a gaming hall, is an establishment for certain types of gambling. Most casinos feature table games such as blackjack, roulette, and craps, as well as poker rooms. They may also offer video machines and other electronic gaming devices. Casinos often host social events such as concerts and comedy shows. They are sometimes combined with hotels, restaurants, retail shops, and other attractions.

In the United States, there are several state-regulated casinos. They include Rivers Casino & Resort in Schenectady, Resorts World Catskills in the Thompson region, Tioga Downs Casino & Hotel in Nichols, and del Lago Casino & Resort in Tyre. There are also a number of Native American and commercial land-based casinos, as well as online gaming.

Casinos are often built near or combined with other tourist attractions and are a popular form of entertainment in many areas. They may also serve as meeting places for tourists and business travelers. In the past, some cities were known specifically for their casinos; for example, Monte Carlo is famous as a destination for casino and other gambling activities. Some casinos are designed to be attractive and fun, while others are meant to be serious and spartan. Casinos are regulated by government bodies to ensure honesty and integrity. The mathematicians and computer programmers who analyze the mathematical odds of various casino games are called casino mathematicians or gaming analysts. This type of analysis is important to a casino’s profitability.
