When wagering against the spread, you bet on the team that will cover the betting line, and not necessarily win the game. Obviously by taking the favorite, a bettor believes that team will not only win the game, but also win the game by a certain number of points to cover the betting line. But when wagering on the underdog, that team does not necessarily have to win the game to cover the line. For examples of point spreads and how those bets are won, please keep reading below where we explain betting odds for the spread in detail.
The bookmaker functions as a market maker for sports wagers, most of which have a binary outcome: a team either wins or loses. The bookmaker accepts both wagers, and maintains a spread (the vigorish) which will ensure a profit regardless of the outcome of the wager. The Federal Wire Act of 1961 was an attempt by the US government to prevent illegal bookmaking.[2] However, this Act does not apply to other types of online gambling.[3] The Supreme Court has not ruled on the meaning of the Federal Wire Act as it pertains to online gambling.

This is because bookmakers are in business to make a profit, so they effectively charge a commission for taking wagers. This commission is known as the vig, short for vigorish, and it's one of the ways that bookmakers stay profitable. They don't charge it just for points spreads and totals either, as it's built into the odds for every wager that they offer.
For example, a negative value (-11.5) next to a team indicates that they are favored by that many points. So you must deduct 11.5 points from their score to determine if they won the game or not. On the other hand, a positive value on the same game (+11.5) means the underdog starts with an 11.5-point lead before the game even begins. In NFL betting, the favorite must win by 12 points or more to cover the NFL spread. The underdog is able to lose by 11 points and still cover the spread.

Baseball. It's America's pastime. A game that prides itself on being perfect in every way imagina-ble. It's almost as much an individual sport as it is a team sport when you consider that in every game and in every inning, a pitcher faces one batter at a time, and whichever player wins that battle brings their team one step closer to victory.

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 ‘total.’ 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.
