When people think of casinos, visions of bright lights, flashing slot machines and big money come to mind. From the glitz and glamour of Las Vegas to tiny mountain towns with 19th century Wild West buildings stuffed with poker tables, there are gambling hotspots all over the United States. Casinos make billions in profits annually by offering patrons a chance to test their luck and win big prizes. Whether you’re looking for the big payouts or just the excitement of playing, this article offers an introduction to casinos, how they make their money and some of the most popular casino games.

The most important thing to remember about a casino is that it is not charity. A casino is a business that makes a profit on the bets it takes in, and it always has a built in advantage over the players. This advantage is usually very small, less than two percent, but it adds up over the millions of bets placed each year by casino patrons. This edge is what gives casinos enough money to build elaborate hotels, fountains and replicas of famous landmarks.

Because of the high stakes involved in many casino games, some gamblers are tempted to cheat or steal, either in collusion with other gamblers or on their own. This is a major reason why casinos have strict security measures in place. Casino employees watch over the games and patrons with a close eye, and most tables are watched by pit bosses and table managers who look for betting patterns that could indicate cheating or theft. Security cameras are also a common sight in most casinos.
