A casino, also known as a gaming house or a gambling hall, is an establishment for certain types of gambling. Casinos are most often built near or combined with hotels, restaurants, retail shops or other tourist attractions. They can also be located on cruise ships or in other places where people gather, such as in convention centers.
Gambling in some form has been found in almost every culture on the planet. There is no doubt that casinos are an excellent source of entertainment for many people, and they have been the inspiration for numerous movies and television shows.
There is one thing that all casino patrons must keep in mind: The house always wins. Unlike charitable organizations that throw free money away, casinos are businesses with the goal of turning a profit. They have a number of built in advantages that ensure they will make more than they pay out to gamblers. These advantages are called the “house edge” and they are designed to ensure that casino games always result in a gross profit for the house.
To ensure this happens, casinos employ a variety of security measures. The most visible are cameras, which give a high-tech “eye-in-the-sky” view of the entire casino floor at any given time. More subtle are routines and patterns that can be recognized by trained security personnel. For example, the way a dealer shuffles and deals cards or the expected movements of players at table games all follow a pattern that can be spotted by security people if something is amiss.
