A casino is a gambling establishment where people can gamble for money. Most casinos are themed to attract visitors. The money made in a casino is mostly spent on gambling. Despite their extravagant theme parks, casinos would not exist without the games of chance. Blackjack, roulette, and slot machines contribute billions of dollars to the U.S. economy each year. Other popular games include baccarat, craps, and roulette. However, these games can also bring the darker side of the casino.
Games offered in a casino include slots, table games, and random number games. Gaming machines are played by one player at a time. There are no casino employees in these games. Table games, however, require one or several players to compete against the casino. Dealers and croupiers are the employees of the casino. Random number games are based on a random selection of numbers, and they do not have a house edge. Some casinos offer complimentary items to customers who play at their establishments.
Several security measures are used to protect a casino from potential burglars. The casino uses elaborate surveillance systems to monitor every area. Cameras are positioned in every window and doorway. Video feeds from the cameras are recorded for later review. Additionally, casinos use computers to monitor the roulette wheel, which can be set to a specific number to prevent a swindle. The computer chips inside the machines determine which games pay out. This prevents players from gaining advantage or losing money by cheating.
