A casino, also known as a gambling house or a gaming room, is an establishment for certain types of gambling. Most casinos are combined with hotels, restaurants, retail shops and other entertainment facilities. Some casinos are operated by governments, while others are private businesses. Casinos are often located in or near large cities and tourist destinations. Some casinos are built as standalone buildings; others are located within hotel and resort complexes.
Some of the more popular games in casinos include blackjack, baccarat, roulette and craps, as well as video poker and keno. Some casinos offer more specialized games, such as sic bo and fan-tan in Asian casinos. Some casinos feature live entertainment such as concerts or comedy shows.
Security is a major concern in casinos. Many casinos use sophisticated surveillance systems to keep tabs on patrons and prevent cheating or other illegal activities. In addition to cameras, security personnel patrol the floor and check player IDs at the entrance. Players are expected to follow dress codes and other rules of conduct.
Many casinos reward loyal customers with comps, or complimentary goods and services. These can include free meals, show tickets, rooms and even limo service. Other amenities may include a cigar lounge, cocktail waitresses and a sports book. Comps are usually based on the amount of time and money a player spends at the casino. High-volatility games, such as video poker, tend to pay out less frequently but when they do, the amounts are larger.
