Making a bet at a sports book is a lot like ordering food at a restaurant. As a patron, you're given a list of what's available and how much it costs.
Sports betting on the Internet is a bit more intimate, but the processes are similar.
You do this by either clicking the team name, a check box, or an icon indicating your choice, and the site generates a form explaining how much you're wagering and how much you can win. All of your bets are kept in password-protected online databases with which you can closely monitor how much money is in your account, how much money is currently in action, which teams or players you've selected, and how your bets have resulted in the past. Of course, keep in mind that the sports book takes a cut of winning bets for itself. In North America, money lines are listed using positive and negative numbers. Sports books in other regions, such as Europe and Australia, use a fraction system.
