A Casino is a place where people gamble and play games of chance. A casino has to be large enough to attract big-spenders and have a range of attractions, like restaurants, free drinks, stage shows and dramatic scenery.
Casinos are ultimately profit centers. They offer all bettors a mathematical expectancy of winning, but they must set limits that prevent them from losing more than they can afford to pay. In order to increase profits, casinos offer comps to loyal players. These may be free or discounted rooms, food, show tickets or limo service. In some cases, even airline tickets are offered to players who spend large amounts of time at the tables or slots.
Slot machines and video poker machines are the economic mainstays of American casinos. The games are easy to play and involve no skill, but the machine gives a predetermined return on investment. In contrast, roulette and blackjack draw more bettors but give the casino a higher house advantage. Casinos often lower their house edge to lure larger bettors and make more money.
The casino is also a lucrative business for organized crime syndicates that have plenty of cash from extortion, drug dealing and other illegal activities. Mafia kingpins have bankrolled the construction of casinos in Reno, Las Vegas and other cities. Some mob figures have taken sole or partial ownership of some casinos and used them as social clubs for their members. However, studies suggest that gambling addiction costs communities more than it brings in by diverting local spending from other sources of entertainment and reducing productivity.
