USA Casino Facts
  • 48 States Regulate a Form of Gambling
  • Lottery is Most Popular Form of Gambling
  • Three States Regulate Online Gambling
  • Online Gambling is Mostly a Grey Area

US Casinos is a complicated topic when it comes to legalization. All forms of gambling fall under states’ right except for sports betting. A federal law known as the Professional and Amateur Sports Protection Act forbids states from expanding sports betting.

States are given the ability to define gambling in their own words. This means that some games, like daily fantasy sports contests, will be legal in some states but not others. Each state’s constitution addresses how gambling is permitted to expand. This often requires a constitutional amendment where voters have the final say after being first approved by the legislature. This can make the road to legal United States casinos a tricky one, especially in conservative states in the South.

Complicated Sports Betting Laws

Sports betting was a states’ right until 1992. That is when the Professional and Amateur Sports Protection Act (PASPA) was passed by Congress. It stopped the expansion of gambling on sports at the state level. Delaware, Montana, Nevada, and Oregon were the only states exempted from it because each had some form of legalized sports betting on the books at the time.

There is a discussion about a repealing PASPA. In the meantime, New Jersey is fighting its reach in federal court. The state lost its first attempt to legalize Nevada-style sports betting by the Third Circuit Court of Appeals.

Online Gambling

Online gambling also falls under a states’ rights issue.  While always believed to be that way, the Unlawful Internet Gambling Enforcement Act (UIGEA) codified that into law.  The UIGEA exempts any intrastate gambling that is expressly permitted under state law.  The only requirements are that there must be age and location verification services to prevent unauthorized access to sites.  This permits poker, casino games, horse racing, lotteries and anything else that does not include betting on sports.

US Casino History

US Casino historyUS casino gambling dates back to 1822. That is when Brown’s Saloon opened near what is now the Colorado and Wyoming border. Casinos in USA dotted the west until the early 1900’s when a conservative movement removed them from every state, including Nevada. It was not until 1931 that gambling returned to Nevada. It was the only state that regulated casinos, although there were many underground networks along the Mississippi River and the East Coast until the 1950’s.

New Jersey was the second state to legalize casinos. That brought Atlantic City into the industry in 1978 with the opening of Resorts International. It took until 1989 for South Dakota, the third legal casino state, to open.

This momentum carried over into the 1990’s.  It was not long before states along the Mississippi River and Native American casinos joined the action.  By the end of the decade, every state that touches the Mississippi River had USA casinos, except Tennessee.  Reservations in the West added casino gambling after creating compacts with states.  The 2000’s saw an explosion of casinos in the northeast.  This eventually led to massive losses in Atlantic City, which fell to the third largest gaming market in the country behind Pennsylvania in 2012.

These US casinos replaced more traditional forms of gambling like lotteries, bingo, and horse racing.  The latter was the biggest victim of the revenue shift.

Online US Casinos

Casinos in United States ComplicatedThe 1990’s brought a new type of gambling to Americans. The Internet made it easy to play right from one’s own home. Online casinos offer all games that are found in Las Vegas and Atlantic City. This includes roulette, craps, blackjack, poker, slots, video poker and card games banked by the house. Sports betting is also common at casinos on the Internet.

The First States to Regulate

Due to the fast-moving pace of the market, state and local governments were not quick to embrace online gambling.  Delaware and New Jersey are the only two states that regulated online casino games.  Both also permit online poker.  Nevada allows its casinos to offer online poker and mobile sports betting.  Online horse racing is available in more than half of states while a few sell lottery tickets over the Internet.

One reason states were originally reluctant to legalize online gambling was because of an odd interpretation of the Wire Act by the US Department of Justice, which claimed states could not regulate the activity.  This opinion surfaced after the Nevada Legislature drafted the first steps in legalizing online poker in the state.  The Wire Act of 1961, which bans interstate sports betting, was the law cited for this opinion.  Sports betting is the only form of gambling specified in the Wire Act.

The Department of Justice’s letter did not match with legal experts and in 2011, it was reversed.  This opened the door for states to legalize intrastate online US casinos.

Online Gambling Expansion

The expansion of gambling to the Internet often requires the same legislative process as the legalization of USA casinos. Some state legislatures have adopted policies without a constitutional ballot under the position that voters already affirmed poker, casino games, horse racing, and lotteries. Other state lawmakers and attorneys general feel that even the regulation of daily fantasy sports would require a constitutional amendment. The complicated legislative process and the special interests are the reason why more states have not joined Delaware and New Jersey in regulating online slots, video poker, and table games.

Players in all states have access to online gambling. You just have to know where to look to get a safe and fair bet.
