Casinos offer customers a variety of games to choose from. Most of these games are based on chance, while others can require skill. Generally, casino games have an edge over the players, known as the house edge, or rake. Casinos also offer complimentary items to customers, known as comps. Regardless of the game, the house has an advantage in some form. The house edge is usually measured in percentages, and the higher the percentage, the more money the casino will make from a player’s win.
Although the concept of casino gaming was originally Italian, it quickly spread throughout Europe. The French invented the most popular games found in modern casinos. Italians started gambling in small clubs and the concept of the casino took hold. Large public gambling halls closed, so gambling moved to smaller venues. The casino has evolved from its humble origins to become the most popular entertainment venue in the world. Today, casinos have elaborate themes and feature everything from a live band to dance floors.
To protect their guests, casinos use a variety of technological advances. They use video cameras and computer programs to oversee game play. For example, chip tracking uses microcircuitry in betting chips to keep track of how much a patron has wagered at any given time. Then, they monitor the casino’s roulette wheel for statistical deviations. Casinos also often offer extravagant inducements to big bettors, such as reduced-fare transportation, free drinks and cigarettes.
