To achieve this balance, the book can move the spread and/or the juice at any time after the first lines hit the NFL odds board, all the way up until kick-off. If there had been too much action on the Packers at Super Bowl 1, the oddsmakers could have made Kansas City a 15-point underdog (+15), in order to encourage more people to bet on the Chiefs. They also could have kept the spread at 14 points and moved the juice, perhaps to –105 for Kansas City and -115 for Green Bay. You’ll often see the books adjust the juice first when the spread is three points; since so many NFL games end in a winning margin of three points (roughly one in six games), moving the spread from 3 to 3.5 points is a pretty big deal, and it might tilt the balance too far in the other direction.
What may look like a jumble of words, numbers, and punctuation is actually a precise and easy-to-read breakdown of the various odds and point spread details your book is offering. Here is a breakdown of each unit of information given above. Once you understand each part of the jumbled details above, you’ll be able to read a sports betting line with confidence.
But what if the basement-dweller team was spotted 24 points? That's the concept behind the point spread. When two teams meet on the football field or a basketball court, one team is typically better than the other. If all bettors had to do was to pick the winning team, everybody would simply wager on the best team and collect their money. Gambling institutions, sportsbooks, and bookies would soon go broke. 

With NFL odds the over/under can vary but usually it’s somewhere between 35 and 47 points. Let’s say in the Colts and Bengals game that the total is posted at 37.5. If Indy scores 27 and Cincy gets 13 points, the total would be at 40 and the over would win. But if the Colts rack up 35, and they shut out the Bengals, the total of 35 would be under.
Reading sports betting lines becomes easier with practice and experience with different sporting events. What looks like a jumble of letters and numbers actually gives a lot of information in a tiny amount of space. Different sports have different types of wagers available, such as the run line in baseball or the puck line in hockey, both of which replace the money line found in our football example. The more experience you have watching and gambling on different sports, the faster you’ll be able to read betting lines.
Thanks to the modern language and a constantly updated Webster's dictionary, there is a word for pretty much anything you can think of. Furthermore, every study, no matter the obscurity has its own word to describe the resident expert. You know, words like paleontologist, botanist, astrologer, just to name a few. In the sports betting world, there are a few words that can be used to describe serious bettors who spend most of their time breaking down bets and looking for advantages that give them the best chance at winning their wager. The word I want to focus on right now is "handicapper". Read More >>
Especially in major tournaments, some sports books offer odds on unusual golf propositions, such as the over/under on the winning score, the over/under on the lowest round by any golfer or the over/under on the finishing position by a particular golfer. For example, the over/under on Woods' finishing position may be 3 1/2. If he finishes first, second or third in the tournament, the "under" wins; if he finishes fourth or worse, the "over" tickets cash.
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.
Another way to beat football point spreads is to shop for off market prices. For example, let's say you're shopping online betting sites and see every site is offering Vikings +7.0. Then, you stumble upon one site that's offering +7.5. There's a good chance that this is a +EV wager, simply because it is out of sync with every other site. Please note that this strategy isn't quite the same as simply shopping for the best lines. Here, you're specifically looking for wagers that are +EV because they're against the market.
If the bookmaker was only confident enough to give Seattle a field goal’s lead on the Patriots, it was clearly going to be a tight game. Oddsmakers aren’t often that wrong about flagship games like the Super Bowl. All things being equal, it’s likely the betting public would have taken the Seahawks to win the game and have been done with it. But throw in the point spread that gave the Patriots 2.5 points, and the proposition seems more equal.
For the purposes of a halftime bet, the game essentially restarts at 0 to 0. According to the halftime spread, the Arizona Cardinals are expected to be outscored by the St. Louis Rams by 3 points throughout the entire 2nd half. A halftime bet of $110 dollars on the Arizona Cardinals would lead to a profit of $100, because, not only did the Cardinals beat the spread, they won the game outright. These bets are taken during halftime, leaving a small window for the bets to be placed. You can track halftime odds easily using our Sportsbook Insider live odds software.
First and foremost, I would look at the overall offensive rankings of both teams.  Even though the saying is that defense wins championship, offense wins games, and an explosive offense could be the difference between you not only covering the spread, but also hitting the over/under bet.  There is a common belief that sharp sports bettors don’t bet favorites and don’t like offensive juggernauts.  I am here to tell you that is bologna.  Some of our biggest wagers each and every football season will be on a well focused large favorite.  There is no better bet out there than finding an attentive favorite that is ready to pour it on.

When betting the point spread, there is almost always a winner and a loser. However, in some instances sportsbook decide to put out a whole number such as -3 for bettors to bet on. If the final score ends with a differential of three points - no matter who wins - the bet is considered a "push" and all money is refunded to both sides since neither team covered the spread.
It is also widely known as the over/under and, just like the point-spread myth, it is not Las Vegas' guess at how many points will be scored in the game by both teams combined. It's a number it feels will encourage just as many bets on the over as the under. If you picked the under 47.5, you want tough defense and the team running the ball to eat the clock. If you pick the over, you want offensive fireworks and long bombs for TDs. In totals betting, you are predicting whether the combined total score will be more than or less than the total.
Often big games will have "proposition" bets on things not directly related to the final score of the game. These are usually abbreviated to "prop" bets. For example, in football whether or not the first score will be a touchdown. In baseball whether a run will be scored in the first inning. In hockey/soccer, whether anybody will score a hat trick. The odds on these are expressed like point spread bets. For example, as I write this the Golden Nugget has the following proposition bet on Super Bowl 49:
A point spread in sports is a figure set by oddsmakers to provide an advantage or disadvantage based on the margin of victory or defeat for a given team. The “favorite” team (labeled with a “-” sign) would be at the disadvantage as they would need to win the game by a set number of points while the “underdog” team (labeled with a “+” sign) would be given an advantage to not lose the game by a set number of points. The reason oddsmakers do this is to provide betting interest for both sides due to one team typically being better than the other.

Then, you stumble upon one site that's offering +7.5. There's a good chance that this is a +EV wager, simply because it is out of sync with every other site.

The National Football League (NFL) remains the only sports league to maintain public opposition to sports betting, however critics have noted that with the move of the Oakland Raiders relocation to Las Vegas in 2019, the NFL has positioned itself for legalization, while simultaneously contradicting its long-held position that sports betting in NFL markets would lead to potential match-fixing.[47] Commissioner Roger Goodell agreed with Manfred in a July 2017 seminar that betting on in-game events, as opposed to the outcome of games, was a more palatable form of sports betting.[48]
No. The point spread is not a prediction of the final score, but rather is created to generate an equal amount of betting on both sides. In a perfect world, a sportsbook will get the same amount of money bet on the Rams to cover as they get on the Patriots to cover. If there is an even amount of money bet on both sides, the house is guaranteed to profit because of the juice (more on that below) placed on bets.

If you see the point spread move, let’s say from -9 on Tuesday to -10.5 on Friday, this is known as a line move. It occurs when there is a surplus of bettors wagering on the same side of the game and sportsbooks move the line to balance the action. That means encouraging more people to bet the other way by making the line more appealing. This reduces risk for the sportsbook, who wants to have an equal handle on each team.
