Although the potential payouts look tempting - many sports bettors have dreamt of cashing in nearly $10,000 by nailing a $10, 10-teamer at 850/1 - they are a bad bet because they are difficult to hit and do not pay anywhere near true odds. This is how the sportsbooks make a lot of their money. For instance, let's say you want to bet a two-team parlay. For two games, there are four different possible combinations of outcomes, thus the true odds are 4/1. However, the sportsbook is only going to pay you 2.6/1 for your efforts, thus giving them a "juice" or vigorish in their favor. However, if you only have $20 to your name for a football bankroll and really like two games, the two-teamer might be the way to go because you could win $52 for your $20 wager.
A point spread, or “the line,” is a number set by oddsmakers to give an advantage to one team and a disadvantage to another team based on the margin of victory or defeat for the two teams. The favorite team is giving up points for purposes of the wager, meaning they not only have to win, but they have to win by X amount of points. The underdog team is getting points for purposes of the wager, meaning they can still lose the game, but they must lose by less than X amount of points.
Total: Also called the over/under, it is a number set by the sportsbooks that proposes a number of points that will be scored in the game by both teams combined. Then, fans predict whether there will be more points or less points than the Â‘total.Â’ If you bet the under 41.5, you are hoping for a tough defensive battle with lots of running game. Pick the over, and presumably you feel this will be a high-scoring game. In short, you are predicting whether the combined total score will be more than (over) or less than (under) the total.
