Security at a Casino starts on the floor, where casino employees keep an eye on the patrons and games. Dealers and pit bosses keep a close eye on each table, and can spot signs of blatant cheating right away. These employees also monitor the slot machines, which use computer chips to randomly determine payouts.

The games in a Casino range from roulette to blackjack. The casino environment is designed to entice players to try their luck and win prizes. It is a fun place to spend an evening with friends and family, but gambling is not the only purpose of a casino. The casino provides a variety of entertainment for guests, and many casinos have elaborate themes to draw in crowds.

There are over 1,000 casinos in the United States, and the number continues to grow as more states legalize gambling. Currently, 40 states have some form of casino gambling. Interstate competition has fueled the growth of these special establishments. There is also a great deal of competition among casinos. The largest concentration of casinos is in the Las Vegas Valley, with Atlantic City and the Chicago area following.

Apart from the games, casinos offer other amenities on their floors. Many are attached to premier dining and beverage outlets, while others feature performance venues for musicians and artists.
