Or more simply, the site is a route to a specific location where bets can be made or placed. The customer first arrives at an internet casino, which provides them with a list of games and options to gamble on. Then that site takes them to a page designed to facilitate the opening of an account and depositing currency. The opening of an account usually requires that the user provides basic information concerning their name and mailing address. Funds are then deposited by using a credit card, electronic check, certified check, money order, or through a wire transfer.
Customers are then free to use the site to place bets and gamble at their discretion.
Choosing from casino type games, to multi-player games, to sports bets, all depending on what the particular site has to offer. Losses will be deducted from the players account. In winning situations, the player requests to 'cash out' and the internet casino then issues a check for the winnings paid, and is sent to the users home address. Simple as that.
