Online Gambling

There are a large number of online casinos, in which people can play casino games such as Roulette, Blackjack, Craps, and many others. These games are played against the "house", which makes money due to the fact that the odds are slightly in its favour. Some unscrupulous sites have been proven to offer rigged games, which are less mathematically fair than they appear.

Online poker

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

Online sports betting

Several major bookmakers offer fixed-odds gambling over the internet, with gamblers typically betting on the results of sporting events.
A relatively new internet joker123 is the bet exchange, which allows individuals to place bets with each other (with the "house" taking a small commission).

Funds Transfers

Typically, gamblers upload funds to the online gambling company, make bets or play the games that it offers, and then cash out any winnings. European gamblers can often fund gambling accounts by credit card or debit card, and cash out winnings directly back to the card.
Because of the questionable legality of online gambling in the United States, however, U.S. credit cards frequently fail to be accepted. However, a number of intermediary companies - such as Firepay, Neteller, and Moneybookers - offer accounts with which (among other things) online gambling can be funded. Casino operators and online poker rooms often offer incentives for using these 'alternative payment methods'.
