During the 2000 fiscal year, $370 billion was wagered in corporate casinos in the United States, or about $1,300 per person. Nearly 93 percent of the money wagered is returned to players as winnings. Casinos have an adjusted annual revenue of $26 billion. In Nevada, casinos generate $4 billion annually. In Atlantic City, casinos collect $1.2 billion in taxes each year. In Illinois and Missouri, riverboat casinos collected $1 billion and $1.8 billion in 2001, respectively.

While casino security starts on the floor, there are also plenty of people in the background monitoring the games and the patrons. Dealers, for example, are focused on their own game, so they can spot potential cheaters before they act. Other employees, known as pit bosses and table managers, keep an eye on the table. The pit bosses and table managers also look out for suspicious betting patterns. All these employees are supervised by a higher-up, who can quickly detect unusual behavior.

Gambling encourages theft, scamming, and cheating. For this reason, casinos invest a lot of money in security measures. This will keep patrons safe while playing. The average American adult plays poker at least once a week. Some European casinos also offer roulette, baccarat, and pai-gow. Those with lower incomes may prefer to play blackjack or baccarat. The casinos in the United States spend a considerable amount of money on security.
