There are a large number of online casinos, where people can play casino games like Roulette, Blackjack, Craps and many others. These games are played against the "house", which generates money due to the fact that the odds are slightly in your favor. Some unscrupulous sites have been shown to offer manipulative games, which are mathematically less fair than they appear.

Online poker

There are a large number of online poker rooms that offer various poker games, most commonly Texas Hold 'Em, but also Omaha, Seven-card stud and other types of games. Players play against each other, with the "house" making their money through the "rake".

Online sports betting

A number of major bookmakers offer fixed odds bets over the Internet, and players often bet on the results of sporting events.
A relatively new innovation on the Internet is the betting exchange, which allows people to place bets on each other (with the "house" taking a small commission).

Fund transfers

Players typically charge funds to the online gambling company, make bets or play the games it offers, and then collect any winnings. European players can often fund gambling accounts with a credit or debit card, and collect winnings directly from the card.
However, due to the questionable legality of online gambling in the United States, American credit cards are often not accepted. However, several intermediary companies, such as Firepay, Neteller and Moneybookers, offer accounts with which (among other things) online gambling can be financed. Casino operators and online poker rooms often offer incentives to use these 'alternative payment methods'.
Payment by check and bank transfer is also common.

General legal issues

Online gambling is legal and regulated in many countries, including the UK and various nations in and around the Caribbean Sea.
The United States Courts of Federal Appeals have ruled that the Federal Wire Act prohibits the electronic transmission of information for sports betting across state lines. There is no law prohibiting gambling of any other kind.
Some states have specific laws against online gambling of any kind. Also, owning an online gaming operation without a proper license would be illegal, and no state currently licenses online gaming.
