There are many countries in the world that do not allow online gambling. These countries include the United States, a few provinces in Canada, most of the European Union, and some nations of the Caribbean. However, some states do allow online gambling. You need to be aware of your local laws before you start gambling online.

Some states have already legalized internet gambling, but others have not yet regulated the activity. Online gambling was widely popular in the 1990s, and it looked like an end-run around government regulation. By setting up a business in an offshore jurisdiction, online gambling operators could provide their services to anyone with a computer and an Internet connection. The popularity of online gambling led to a number of regulatory investigations by Congress and the Department of Justice.

The connection between internet gambling and problem gambling is still unclear. Several Swedish studies, for example, did not support the idea that online gambling would attract people with gambling problems. In fact, offline gamblers were more likely to report mental and health problems. However, in an Australian study of problem gambling and at-risk gamblers, there was a strong association between problem gambling and Internet gambling.

A large percentage of online gambling wagers are placed on horse racing. All major sports books, betting exchanges, and internet bookmakers offer horse racing betting markets. Another popular form of online gambling is mobile gambling, which involves playing games of chance or skill using a wireless Internet connection.
