A casino (also known as a gaming house or a gambling house) is an establishment for certain types of gambling. It is often combined with a hotel, restaurant, retail shops or other entertainment venues. The term casino may also refer to an entire building or complex.

The casino industry is regulated by government bodies, and the games offered are dictated by law. Some states have special laws governing how casinos operate, including the size of the gaming floor, the maximum bets allowed, and whether or not children are permitted in the gaming area. Most casinos have security measures in place to prevent cheating and stealing by patrons or staff, either in collusion or independently. These measures include security cameras, as well as manned or automated systems to monitor game results and payouts. Casinos are a popular form of gambling, and are found in cities around the world.

Casinos are a source of entertainment for both experienced gamblers and those who have never set foot inside one before. They are famous for their flashy lights, lively music and high stakes table games. They are also a great place to socialize with friends or meet new people. In addition to tables and slot machines, some casinos offer a variety of other games such as poker, sports betting and keno. Casinos also offer comps to their best players, which can include free rooms and meals, show tickets, limo service and even airline tickets.
