A casino is a public room or building where gambling games (such as roulette, craps, blackjack, poker, and slot machines) are played for money. It is also a place where people socialize and relax. Casinos are generally regulated by government law. They are sometimes also known as gaming houses or chinese gambling houses.

In a game where players compete against the house, such as poker, casinos earn revenue by taking a commission from winning bets, which is known as the rake. In games that are based on luck or chance, such as slots and table games, the house has a mathematical advantage over the players, which is called the house edge.

Despite their seamy reputation, casinos are a significant economic force in many cities and countries. They offer jobs to local residents and attract visitors who spend money on food, beverages, and lodging. The industry is expanding globally.

Some casinos specialize in specific games or regions. For example, Asian casinos often feature traditional Far Eastern games such as sic bo and fan-tan. Others offer more Western games such as baccarat and chemin de fer.

Other types of casinos include those that provide skill-based games like crokinole, sjoelbak, and carrom. These games require keen dexterity skills and usually involve flicking or sliding disks over specially designed boards or tables. In these casinos, the player is not competing against the house but rather is playing against other players. They may or may not win.
