A casino is a facility for certain types of gambling. The modern casino is like an indoor amusement park for adults, with the vast majority of the entertainment (and profits for the owner) coming from games of chance. Slot machines, black jack, roulette, craps, and keno are some of the most popular games at casinos. While musical shows, lighted fountains, shopping centers, and lavish hotels may draw in the crowds, casinos would not survive without the games of chance.

The casino industry is full of glitz and glamour, but there is a dark side to it. Most American casinos serve alcohol, which increases the amount of money patrons lose and decreases their judgment, causing them to gamble more recklessly. In addition, casino employees keep close watch on patrons to prevent cheating or stealing. The casinos also use cameras to monitor the patrons’ actions. Elaborate surveillance systems offer a high-tech “eye in the sky” that allows security workers to watch every table, change window and doorway at once.

Despite the glamour, the casino is a business and makes its money by taking advantage of people’s addiction to gambling. Gambling isn’t a hobby or charity; it’s a money-making enterprise that comes with built in advantages for the house, which, over time, erodes the players’ bankroll. The house edge is usually very small—less than two percent—but the millions of bets placed by casino patrons add up quickly, resulting in large losses. The casino also pays out winnings at a very fast pace to encourage people to keep betting.
