A casino is a place where people play different games for fun and for making money. It is a popular form of entertainment among many people. Some casinos are big while others are small and have only a few tables. The games played in a casino can be different and are very interesting. Some of these games are based on luck while others are based on skills. There are also some that have a mixture of both. Some of these games include Blackjack, Craps, and Roulette.
While musical shows, lighted fountains, lavish hotels and elaborate themes help draw in the crowds, casinos exist mainly to make money from gambling. Slot machines, blackjack, craps, roulette and other games provide billions in profits to US casinos every year.
With large amounts of cash changing hands, both patrons and staff may be tempted to cheat and steal, in collusion or independently. To counter this, casinos employ a number of security measures. The most obvious are the cameras located throughout the building. Casino floor employees keep their eyes on the action to spot blatant cheating techniques such as palming, marking and switching cards or dice. Table managers and pit bosses watch over table games with a broader view, watching for betting patterns that suggest cheating.
Some casinos use more sophisticated surveillance systems. For example, some have catwalks in the ceiling, allowing surveillance personnel to look down on activities at table and slot machines through one-way glass.
