For example, you could find the New York Giants +10.5, and the Philadelphia Eagles -10.5.
How this works is that the favorite team always has a negative value alongside it, and the underdogs a positive value.
In our example, the Philadelphia Eagles are the favorites to win by 10.5 points in this game.
Meanwhile, the underdog in this game are the New York Giants, which has a +10.5 value, meaning online sports bettors will profit if the New York Giants win the game outright or lose by 10-or-fewer points.
All point spread wagers also have a price or commission, which if not stated by the Las Vegas sportsbooks is assumed to be -110.
In other words, risk $110 to profit $100, or if simplified, every dollar bet you bet, the sportsbook receives 10 cents, rather than an even 50/50 line in which you bet a dollar to make a dollar. This extra price youβre charged is referred to as the vig or juice and is how the sportsbooks make their profit.
When betting online, youβll commonly find point spreads that have half points involved (example -2.5 / +2.5), thus ensuring there is no way for a sports bettors wager to be tied, otherwise known as a push.
