Whether you like to spin the roulette wheel, put on your best poker face or throw dice at the craps table, casinos are where you go when you’re ready to try your luck. They’re also the perfect place for great food and tasty sips. Plus, they’re usually packed with exciting music and energetic crowds. The map below shows all legal land-based casinos in the United States.
Despite all the extras, most casinos are actually quite simple. Each game has a mathematical expectation of winning or losing, which means the casino will always have an advantage (though this can vary from game to game). This advantage is called the house edge. In order to make up for this, casinos use many different techniques to keep gamblers happy. These include free food and drinks, discounted or complimentary hotel rooms, and special events such as stage shows or dramatic scenery.
Casino security is another important aspect of a casino’s operation. A typical modern casino has a physical security force and a specialized surveillance department that operates the casino’s closed circuit television system, often called “the eye in the sky.” The casino’s staff members are trained to spot certain patterns or deviations from the norm that could indicate cheating or other suspicious activity.
The Mob once owned most of the world’s casinos, but thanks to federal crackdowns and the threat of losing a gambling license at even the slightest hint of mafia involvement, legitimate business owners now control the vast majority of America’s gaming establishments. However, some economists argue that the net value of a casino to a community is negative due to increased costs for gambling addiction treatment and lost productivity.
