Casinos are a great source of entertainment. They attract guests with lighted fountains, musical shows, shopping centers and elaborate hotels, but most of their profits are made from games of chance. Some of the more popular games are blackjack, roulette, poker, baccarat and slot machines. These games provide excitement and the hope of winning big money. While some people do win, most lose money in the long run. Many casinos have security measures to prevent cheating and theft.

Because casinos deal in large amounts of currency, they are prone to theft and other criminal activities. Both patrons and staff may be tempted to steal or cheat, in collusion with one another or on their own. Many casinos have extensive security measures to discourage these actions, including a high-tech eye-in-the-sky surveillance system and security cameras located throughout the facility.

Casinos employ local residents and provide a source of employment for those seeking jobs outside the primary labor market. This often decreases the local unemployment rate. But local changes in unemployment rates need to be compared with other factors, such as population dynamics and statewide business cycles. Moreover, the promise of bringing in skilled labor from other regions may be unfulfilled. When looking at the local unemployment rate before and after a casino opens, it is important to consider whether these new workers are replacing lower skilled jobs with higher ones. If so, the local unemployment rate will remain unchanged. Otherwise, the local jobless rate will rise.
