High Quality Content by WIKIPEDIA articles! Online gambling is a general term for gambling using the Internet. Online poker tables commonly offer Texas hold 'em, Omaha, Seven-card stud, razz, HORSE and other game types in both tournament and ring game structures. Players play against each other rather than the "house", with the card room making its money through "rake" and through tournament fees. There are a large number of online casinos, in which people can play casino games such as roulette, blackjack, pachinko, baccarat and many others. These games are played against the "house", which makes money due to the fact that the odds are in its favor.
