Whenever you think of Casino, you probably imagine a big gambling venue such as Las Vegas or Atlantic City. But this isn’t the only way to gamble in America. In fact, the country has thousands of land based casinos that draw gamblers from all over the world and generate billions in revenue each year.

The exact origin of gambling is unknown, but it has been part of almost every culture throughout history. Whether you are interested in video poker, roulette or blackjack, the United States has a casino for you.

Gambling in modern times is regulated and legalized by many state governments. It is estimated that there are more than 40 states that allow some form of legal gambling, including land based casinos. While some states have only a few casinos, others, such as Nevada and New Jersey, are known primarily for their gambling establishments.

Most casinos make their money through games of chance that have a built in long term disadvantage to the house, known as the house edge or vigorish. These edges can be quite small, but over time they add up to substantial amounts of money for the casino.

Because of the large amounts of money that are handled within a casino, security is a major concern. Modern casinos typically divide their security efforts between a physical force that patrols the facility and a specialized surveillance department. The former looks for signs of suspicious or definite criminal activity while the latter operates the casino’s closed circuit television system.
