Online gambling has grown significantly over the past few decades. In 1996 there were only fifteen gambling websites; by 1998, there were over 200. A Frost & Sullivan study showed that in 1998, online gambling revenues reached $830 million. The first online poker rooms were also introduced during this time. In 1999, a bill called the Internet Gambling Prohibition Act (IGPA) was introduced in the US Senate, which would have prohibited US citizens from participating in online gambling. However, the legislation was not passed, and multiplayer online gambling was also introduced.

In order to participate in online gambling, a computer with an Internet connection is necessary. Most gambling sites only accept Windows-based PCs, although some have gradually introduced Mac compatibility. The quality of the site you choose should be based on how comfortable you are with risking your money. In addition, it is important to research the gambling laws in your jurisdiction before engaging in online gambling.

Several countries have enacted laws to restrict the practice of online gambling. However, some states and provinces in the United States and most countries of the European Union have legalized the practice. There are also several countries in the Caribbean where online gambling is legal. However, in these countries, online gambling service providers are required to obtain a license to operate in the country.
