Generally, a casino is a building where people can play games of chance, such as roulette, blackjack, and poker. These games are supervised by casino employees who keep an eye on each player and game.

A typical casino features dramatic scenery and stage shows. Guests can also enjoy complimentary items such as drinks and cigarettes.

Casinos are highly profitable businesses, but there are a number of negative consequences. Many people become addicted to gambling, putting their personal productivity at risk. They also encourage cheating.

Gambling encourages people to commit crimes. A study by the Wall Street Journal found that five percent of casino patrons are addicted. The cost of treating gambling addictions offsets economic gains from casinos.

Gambling in the United States is highly regulated. However, casinos continue to grow. There are more than 1,000 casinos in the United States. The top three revenue-generating regions are Las Vegas, Atlantic City, and Chicago.

Casinos also offer extravagant inducements to big bettors. These incentives, called comps, are based on how long players stay, and how much they bet.

Casinos also offer reduced-fare transportation to big bettors. Some casinos offer free drinks, cigarettes, and gifts to gamblers.

Many casino employees monitor the games to prevent cheating. There are cameras in the ceiling and on each table to watch for suspicious behavior. These cameras record the games and can be reviewed after the fact.

Casinos are staffed by dealers who shuffle the cards. The tables are monitored by pit bosses and table managers who watch for patterns of cheating. Casinos also monitor the roulette wheels regularly to detect statistical deviations.
