A Casino is a place where people can gamble on games of chance. There are casinos in a variety of locations around the world, from seaside gambling venues to mountaintop locales. These places often add luxuries and amenities to attract patrons, such as restaurants, free drinks and stage shows. But they can also be simpler places that focus on gambling activities.
Most casinos make money by offering a game of chance with a built-in statistical advantage for the casino, known as the house edge. This may be only a few percent, but it can add up over time. Casinos use mathematicians and computer programs to calculate the house edge for each of their games, and they adjust machines accordingly. Casinos also comp players, giving them free hotel rooms, dinners, tickets to shows and limo service depending on how much they play.
Something about the presence of large amounts of money in casinos encourages both patrons and staff to cheat or steal, either in collusion or on their own. This is why most casinos spend a lot of time and money on security measures. In addition to cameras, casinos employ a number of security personnel who monitor and oversee table games, making sure that patrons are not palming cards or marking dice in ways that can be seen by dealers. Casinos also have a higher-up person who tracks each employee, noting whether they are following policies and observing other employees to spot patterns of behavior that could indicate cheating.
