Online gambling (or Internet gambling) includes poker, casinos and sports betting. The first online casino was in 1994. Many countries restrict or ban online gambling, but it is legal in some provinces in Canada, most countries of the European Union and several nations in the Caribbean.
Online poker tables commonly offer Texas hold 'em, Omaha, Seven-card stud, razz, HORSE and other game types in both tournament and Cash game structures. Players play against each other rather than the "house", with the card room making its money through "rake" and through tournament fees.
Sports betting is the activity of predicting sports results and placing a wager on the outcome. Usually the wager is in the form of money.
Online bingo is the game of bingo (US|non-US) played on the Internet.
Most lotteries are run by governments and are heavily protected from competition due to their ability to generate large taxable cash flows. The first online lotteries were run by private individuals or companies and licensed to operate by small countries. Most private online lotteries have stopped trading as governments have passed new laws giving themselves and their own lotteries greater protection. Government-controlled lotteries now offer their games online.
