As you can see, understanding the -110 in sports betting is pretty basic once you realize what it represents. You can also apply this knowledge to other odds as well, such as the money line. This kind of bet is different because you are betting who will win the game straight-up, which causes the odds to be different for each game (instead of -110 for everything).
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.
There are many ways that you can bet on football and I will go over all of the different options below. The first and most common bet is the straight bet, which simply means the team wagered on must win by the point spread given at the time of the wager. Most of the time the odds on a straight bet is -110, which means for every $110 bet, you win a $100 back. An example of a straight bet is if the team you bet on is a 6 point (-6) favorite, also known as giving up 6 points. Then in order for you to win, the team taken in the wager must win by more than 6 points in order to collect your winnings. If they win by 6, then this will be called a push and your original bet will be refunded to you. You can also bet on the totals, which is also known as the over/under bet. The totals bet is The combined score of both teams for games wagered on, all totals pay out at -110, which is $110 dollar bet makes you $100, no matter if you bet on the over or the under. If the total score equals the line, then the bet is a push and you get your original bet back. Another type of bet is the money line bet. This bet is simply that team wagered on just has to win the game. The odds on these games vary depending on the disparity between the favorite and the underdog. You obviously will win more betting on the underdog; however there is a reason why these bets pay more because the odds of the underdog winning are decreased. Although betting the moneyline can sometimes return a big sum, it is wise to know that the bookmakers hold percentage is much larger than a typical straight bet on the side or total of a game. A classic straight wager on the point spread is almost always dealt at -110 on both sides which is 20 cents of vigorish. Compare that to a double digit favorite in college football with a money line of -600/+450 and you can see the extra 130 cents of vig added in.
Point Spread: The point spread remains the favorite way to wager on pro football, regardless of how many new forms of wagering come on stream. ItÂ’s called the line or spread and itÂ’s known as betting Â‘sides.Â’ The common misconception is that Las Vegas sets the spread as its best guess at the margin of victory. But really, it's a number they feel that is a perfect balance and will see an equal number of people to bet the underdog as on the favorite. A negative value like -6.5 means that team is favored by 6.5 points. So deduct 6.5 points from their total score. A positive value on the same game would be +6.5 (add 6.5 points to their final score) and would make that team an underdog of 6.5 points. The favorite must win by at least seven points to cover the spread. The underdog can lose by six points and still cover.
