NFL games are popular moneyline games because the specific outcomes can sometimes be difficult to predict for casual players. Moneyline games are also profitable when they win, which is one reason why the NFL is a favorite among sports gamblers. An example of a money line is: New York Giants (-120) vs. New Orleans Saints (+130). In this game, a bet of $120 on the Giants is necessary to win $100, while a bet of $100 would win $130 in the case of a Saints win. The team with the minus sign is the favorite and indicates how much a player must put down in order to win $100. The team with the plus sign is the underdog and indicates how much a player would win for a bet of $100.
As an example, let’s consider a matchup between the Indianapolis Colts and the Cincinnati Bengals. In our scenario, the Bengals are the home team, which means they will be listed last and the Colts, as the visitors, will be on the odds slip first. If Indy’s rotation number is 101, then Cincy’s rotation mark would be 102. When you place a bet live at a Vegas sportsbook or over the phone, you would say the number of the team on which you want to wager and not the name.
Sports betting has been around since 1000 B.C in China, where betting on animal fights was commonplace. In ancient Rome, one could wager on the Gladiatorial games. The idea of betting on sports is as old as organized sport itself. But up until the 1940s, bettors were fairly limited in what kind of bets they could make. The standard system of odds would allow bets on, for example, the 3-1 odds that the Steelers would beat the Browns.
