A casino, also known as a gaming house, is an establishment for certain types of gambling. Successful casinos rake in billions of dollars each year for the companies, investors, and Native American tribes that own and operate them. They also benefit state and local governments through taxes and fees.
Unlike most other forms of gambling, casino games have built-in advantages that guarantee the house a net profit, even for small bets. These advantages are called the house edge and vary by game. In some cases, they can be as low as two percent. These small advantages, multiplied by the millions of bets placed by patrons each day, add up to huge profits. These profits allow casinos to lavish their big bettors with extravagant inducements, such as free spectacular entertainment, luxurious living quarters, reduced-fare transportation, and free food and drinks while gambling.
Casinos rely on technology for security as well as for the operation of their games. Elaborate surveillance systems give a high-tech eye-in-the-sky view of the entire casino floor and can be directed by security workers in a separate room filled with banks of monitors. They can also be adjusted to focus on suspicious patrons.
People gamble to have fun and get away from the pressures of everyday life. Many enjoy casino gambling as a social activity with friends, family, and coworkers. They also go to casinos for the entertainment, food, and drink. In a survey conducted by Gemini Research in Nevada, respondents who acknowledged participating in casino gambling selected slot machines as their favorite game. Table games, such as blackjack and poker, and gambling on sporting/racing events each received less than 6% of the vote.
