A Casino is a place where you can gamble and play games of chance. The modern casino is like an indoor amusement park for adults, with the vast majority of entertainment (and profits for the owners) coming from gambling. Slot machines, black jack, roulette, craps, keno and other games provide the billions of dollars in profits that casinos rake in each year. Casinos have many amenities to lure customers, including free drinks, stage shows and elaborate hotel towers and structures.

Casinos are a major source of revenue for many cities and states. In addition to their obvious financial benefit, they often bring in tourists who would otherwise not visit the area. They are also a significant employer. In the United States, there are more than 1,000 legal land-based casinos. The best known are located in Las Vegas, Nevada and Atlantic City, New Jersey. There are also casinos on American Indian reservations, which are exempt from state gambling laws.

Something about gambling seems to encourage people to cheat, steal or scam their way into a jackpot. That’s why casinos spend a lot of money on security measures. Elaborate surveillance systems offer a high-tech eye-in-the-sky that allows security personnel to watch every table, change window and doorway. They can even be adjusted to focus on certain suspicious patrons by security workers in a separate room filled with banks of security monitors. Casinos also have catwalks in the ceiling that allow them to look directly down, through one-way glass, at tables and slot machines.
