Security at a Casino begins on the floor. Employees constantly monitor the games and patrons. Dealers are focused on the game they are playing, so they will often be able to spot signs of cheating. Table managers and pit bosses monitor the table games, looking for patterns in betting and the use of a cheating strategy. Each employee is closely watched by a higher-up. If they do notice anything suspicious, they should be alerted.

Gambling was previously illegal in the United States, but legalization has helped the industry grow. There are over 1,000 casinos in the United States, and their numbers continue to increase as more states make it legal. The casino industry has become so popular that 40 states have some form of legalized casino gambling. Though the casinos have not defined a region, the Las Vegas Valley and Atlantic City are home to the largest concentration of casinos. The Chicago region and Atlantic City are second and third on the revenue list.

Although casinos are a great thing for the local economy, some people wonder how a casino will affect the unemployment rate in the area. In a rural area, the employment rate may remain unchanged or even decrease, as the majority of casino jobs will require some level of skill. However, in an urban area, a casino may attract skilled labor from outside of the area, thus reducing unemployment in the area. This is because the casino is generating tax revenue, and the local economy will benefit from this new investment.
