The casino industry is huge and includes a diverse range of businesses. It has a broad base of customers from across the country and around the world, and it employs millions of people. It also generates billions of dollars every year for the companies, investors, and Native American tribes that run it. Its success makes it a powerful force in the economy and one that is not likely to go away anytime soon.

Casinos have a wide variety of security measures in place to protect patrons and their money. Cameras are constantly monitoring the action at table games to ensure that players are following rules and procedures. Casinos also rely on electronic systems to supervise the games themselves, with chips that have built-in microcircuitry, roulette wheels that are electronically monitored minute by minute and can reveal any statistical deviation quickly, and wholly automated versions of traditional casino games that allow players to bet by pushing buttons.

In addition, casinos often offer traditional Far Eastern games such as sic bo (which was introduced to a number of European and American casinos in the 1990s), fan-tan, and pai-gow. These games are generally played at smaller tables than the blackjack, poker, and craps tables.

The casino business is highly competitive, and successful casinos are usually very profitable. Many casinos give “comps” to big spenders, who may get free meals or hotel rooms, tickets to shows, or even airline and limo service. This is because casino profits depend largely on the amount of money that gamblers lose, rather than their winnings.
