Whether you’re a high roller or someone who just likes to try their luck, casinos are the place to satisfy your gambling cravings. They’re glamorous and fun, with plenty of great food and drinks to help you keep going back for more.

The precise origins of casino games aren’t known, but gambling in some form has been around for as long as human civilization itself. In modern times, it has become a global industry that draws in millions of people each year and generates staggering amounts of money.

In America, a casino’s main source of income comes from slot machines and table games like roulette and craps. These games, which require a low house advantage (less than 1 percent), attract bettors from all over the country who can play for hours without spending much. The casino rewards these players with comps — free hotel rooms, meals and even limo service and airline tickets based on how much they gamble.

Casino security starts on the floor, where dealers keep their eyes peeled for suspicious betting patterns and other blatant cheating. Cameras in the ceiling allow security staff to watch every table, window and doorway in a separate room filled with banks of monitors.

The elegance of a place like the Bellagio in Las Vegas or the Casino de Monte-Carlo in Monaco has helped make these spots world famous. But there are plenty of other places where gamblers can get their fix, from the sprawling Foxwoods in Connecticut to Germany’s glitzy Baden-Baden resort.
