A casino is a facility for certain types of gambling. Often it is combined with hotels, restaurants, retail shops and other entertainment venues. Casinos are most famous for their table games, but some offer sports betting and even horse racing. Some are located in beautiful locations, such as the Bellagio fountains in Las Vegas or the Casino de Monte Carlo in Monaco. Others are built in cities that are well known for their history, such as Baden-Baden in Germany.
Something about the large amount of money handled within casinos encourages both patrons and staff to cheat and steal, either in collusion or on their own. This is why casinos spend a great deal of time and money on security. Cameras are everywhere, with workers able to monitor every corner of the casino from a room filled with rows of screens.
Casinos earn money by charging a “house edge” on bets placed by their patrons. This is usually a small percentage, but over time it adds up to substantial profits. The house edge can be adjusted by the casinos by changing payouts on different machines or by giving free items to big players (complimentary goods or services are called comps).
Besides the usual table games, casinos also specialize in games designed to appeal to specific groups of gamblers. For example, Roulette is a mainstay in Europe, where casinos reduce the house advantage to less than 1 percent to attract high-stakes players. In America, however, Craps and slot machines are the economic lifeblood of most casinos, because they require only a small percentage of bettors’ money.
