A casino is a gambling establishment. Casinos feature a variety of games of chance and skill, such as poker, blackjack, and roulette. Most of these games have a mathematical advantage for the house (known as the expected value), which ensures that casinos will, on average, make money. Casinos also often pay out winnings a percentage at a time and, in the case of poker, take a percentage of the money bet or charge an hourly fee.
In the modern era, most casinos employ video cameras to monitor players and employees. They also use computers to oversee the game operations, for example by putting in place “chip tracking” systems that enable casinos to follow betting minute by minute and detect any anomaly; and electronic monitoring of the results of roulette wheels to discover statistical deviations as quickly as possible.
Many states have legal land-based casinos, although Nevada and Atlantic City are the best known. Other casinos can be found in exotic locales like Venice, Monaco and Singapore. These casinos promise an unforgettable experience, combining entertainment, dining and luxury accommodations with gambling.
The Bellagio in Las Vegas is one of the most renowned and elegant casinos, with its fountains that dance and its high-end restaurants. It was also featured in the movie Ocean’s 11, giving it a worldwide reputation. Similarly, the elegant spa town of Baden-Baden, Germany, once attracted royalty and aristocracy from across Europe 150 years ago. Today its casino offers a range of traditional table and slot games, along with a lively sports book that attracts hardened dollar spinners and novices alike.
