They also employ specialized casino security departments to patrol the premises and respond to calls for assistance or suspected criminal activities.
Most casinos have a number of tables for various card games, such as blackjack, poker, and roulette. They may also offer sports betting and other forms of entertainment. Some have restaurants or bars that serve drinks and food. The casino is an important part of the gambling industry, and it offers substantial profits for its owners.
The United States has more casinos than any other country, with about 2,147 operating legally. Las Vegas is the largest gambling city in the world, and its economy depends heavily on casino gambling. Other large gambling cities include Atlantic City, New Jersey; and Chicago, Illinois.
