To prevent the occurrence of fraudulent activities, casinos invest in security systems. The casino’s security is based on the patterns and routines used for games. For example, dealers shuffle and deal cards. There are certain betting spots at each table. Those predictable motions and reactions enable casino security to catch suspicious behavior. While it’s hard to monitor the entire casino floor, surveillance cameras do help. If a suspicious person is spotted, the casino can take immediate action.

While there are a few security measures to be taken, casinos do not have clocks. These would pose an extreme fire hazard. Therefore, casinos instead use gaudy wall coverings and floor coverings that have a cheering and stimulating effect on the ambiance. Colors like red are common in casino decorations. Many people think that the red color makes them lose track of time. This may be true, but casinos have taken steps to avoid this problem.

There are three types of casino games: table games, gaming machines, and random number games. Gaming machines are single player games that involve no casino employees. Table games, on the other hand, require a dealer or croupier. The house edge on these games is called the rake. While table games are entirely random, some of them have an element of skill that allows advantage players to eliminate the house edge. If this is the case, players are referred to as advantage players.
