A casino is a place where people gamble on games of chance. It can include a variety of different gambling activities such as slot machines, blackjack, roulette and craps. Some casinos are more extravagant than others and feature stage shows, lavish hotels, shopping centers and other amenities. But the core business of a casino is still gambling and most of the billions of dollars that casinos rake in each year come from that.

Because large amounts of money are handled within a casino, security is a key part of the operation. Security measures start on the casino floor, where dealers watch over their tables to make sure no one is cheating or stealing. Pit bosses and table managers monitor each game and player, looking for a pattern that might indicate cheating; and electronic systems track betting chips with built-in microcircuitry to help the casino keep tabs on what is being wagered minute by minute.

Gambling is an addictive activity, and casinos have to spend a lot of time and money on security to protect their patrons and their bottom line. Many critics argue that the gambling industry contributes little or nothing to local economies, and the cost of treatment for compulsive gamblers more than offsets any profits casinos generate. But in the end, it is up to each individual to decide if gambling is something they want to participate in.
