While we aren't exactly sure at which dollar amounts or what formulas sportsbooks use to determine when they shift the lines, we do know why they do it. It is their attempt to minimize their risk as much as possible and guarantees sportsbook profit. Lines will also move if something major happens (like Lebron breaking his leg or something) so keep an eye out for this. Ultimately, the shift in the line is done for the exact same reason to keep the same amount of money on both sides of the game. As you'll see in the strategy and tips section, shifting lines do present some interesting opportunities for sports bettors.

Typically hockey is not a popular sport when it comes to point-spread betting because most games are decided by only a goal or two. Sports like football and basketball are better for point-spread betting mainly because they are higher scoring sports. However, Proline does offer NHL point-spread betting and it can get confusing so let’s take a look at how it works.

*Sometimes with NFL odds you’ll see a spread posted as a whole number. Decimals or fractions are usually utilized to ensure there won’t be a tie. If in our example the spread was reset to 10 with the Colts favored and they win by 10, then the game is considered to be a tie, which in betting terms is called a push. If there is a push all bets are off and the sportsbooks return all wagers back to the bettors.*

*The odds listed are a primary way of gauging the play in the game. There are hundreds of mismatches every single year and the leveling of the playing field has been very helpful in resolving that particular problem. With the use of odds, bookies are able to acquire an equal number of wagers on each team, which assures them that they get money regardless of who wins.*

*The odds given on the spread are usually -110 unless otherwise noted. It is not uncommon to see one side of the spread being -105, with the other side being -115. If you don’t see any odds listed for each side of NFL spreads you are supposed to assume the odds are -110 on each. Not sure how to read NFL betting odds? Check out our Sports Betting Odds guide.*

`The first thing you’ll notice with moneyline odds is that there is either a positive or negative sign in front of the number. What that sign denotes is how much you’ll win betting on each side. If there’s a positive sign next to the odds, that indicates the amount of money you would win if you bet $100. If the odds on a tennis player said +150, that means that for a $100 bet, you would win $150. Now if there is a minus sign in front of the odds, that is the number that you would have to bet in order to win $100. For example, if a football team was -250, that means you’d have to bet $250 to win $100.`

Buying points: Changing the point spread in order to favor your chances of winning. The odds here are proportionally lowered. Buying points allows the option of moving the point-spread on totals in your favor when betting on football or basketball (college and pro). You’re able to move the line up to 2 points. For every ½ point you want to buy, you must risk 10% (10 cents) in extra juice (except when buying on/off of a 3 in NFL).

For beginning sports gamblers, moneylines (sometimes called money lines or American odds) can be confusing. Unlike point spreads, which are concerned with who wins and by how much, a moneyline is solely dependent upon who wins. Moneylines are used most commonly in low-scoring games like baseball or hockey, but they may also be used in boxing and other sports.

*While we're going to cover this extensively in the moneyline section of the Basketball Betting Guide, we'll touch briefly on what the -110 means here. -110 refers to the moneyline payout for a particular bet. If you were to bet $100 on a basketball point spread paying -110 and win, you would be paid out a profit of $90.90. The easy way to figure out the amount you will get paid with minus moneyline odds is to divide your bet size by the absolute value of the betting odds and multiply that number by 100.*

A teaser is a bet that alters the spread in the gambler's favor by a predetermined margin – in American football the teaser margin is often six points. For example, if the line is 3.5 points and bettors want to place a teaser bet on the underdog, they take 9.5 points instead; a teaser bet on the favorite would mean that the gambler takes 2.5 points instead of having to give the 3.5. In return for the additional points, the payout if the gambler wins is less than even money, or the gambler must wager on more than one event and both events must win. In this way it is very similar to a parlay. At some establishments, the "reverse teaser" also exists, which alters the spread against the gambler, who gets paid at more than evens if the bet wins.

## In most cases, the favorite will be the team with a negative moneyline (in some cases both teams can have a negative moneyline if they are both closely matched). A line of -160 means that you would have to bet $160 to win your base amount of $100. A team with a moneyline of -130 wouldn't be favored nearly as strongly as a team with a moneyline of -330.

Identify the type of line you are looking at. All online sports books offer you the chance to have your lines in an "American" or "Money line" version. If I were you, I would use this as my standard. An "American" line uses either a + or - before a number to indicate odds. So a -120 and a +120 are two very different odds on a team… I will explain the differences shortly. Two other less common variations exist: decimal odds and fractional odds.

*The last number in the top two rows of our sports line example is known as the money line. If you’re not interested in betting on the point spread, you can wager on a team to win outright. The plus sign next to the underdog (in our case, the Giants) indicates how much money you’ll earn for every $100 you bet on the money line. Conversely, the minus sign next to the favorite’s line tells you how much you have to wager in order to win $100. In our example, a $100 wager on the Giants earns you $300 should they pull off the upset, while a bet of $405 on the Cowboys will net you an extra $100. Representing odds in units of $100 makes placing different size bets easy; if you want to bet $10 on the Giants, you stand to earn $30 if they win, while a $40.50 bet on the Cowboys will net you an additional $10.*

_{For UK spread betting firms, any final outcome that finishes in the middle of the spread will result in profits from both sides of the book as both buyers and sellers will have ended up making unit point losses. So in the example above, if the cricket team ended up scoring 345 runs both buyers at 350 and sellers at 340 would have ended up with losses of five unit points multiplied by their stake. }

`A wager on the Giants on the spread does not mean that New York has to win the game in order for you to win cash. All the G-Men have to do is come within 8 points of the ‘boys, and you’re a winner. You determine a winning or losing point spread by adding or subtracting 7.5 from the final score, depending on which side you laid your bet. If you’re confident that New York will at least come within a touchdown of beating the Cowboys, or beating them outright, then you’d wager on the spread in favor of New York.`

__However, there are some good values with teaser bets if you know how and where to find them. For instance, the six-point teaser is an especially effective bet in the NFL, where most games are tightly contested and six points can make a world of difference. For instance, in our previous example, the Bears would go from laying six points to simply needing to win if you put them on a teaser bet. Conversely, Detroit backers could get 12 points instead of the starting six. (Source: Doc's Sports Service)__

**Here in this point spread example for the NFL, the Falcons are playing the Panthers. Atlanta has been set as a three-point favorite on the betting line. That means that for Atlanta to cover the spread that has been set, they will need to win by at least four points. And for Carolina to cover the point spread, they can do so with a loss by two points or less, or obviously a win straight up. If the Falcons win by exactly three points, the bet would result in a push with no payouts.**

*Without point spread betting, placing a wager on our team to win these games would be financial suicide. Point spreads create an even playing field for sports bettors. Even if your team is supposed to lose by 20 points, you can still bet on them if you think they're going to have a better day than predicted. If you've ever wondered why someone was still cheering and going nuts at the end of a blowout, you can bet they were sweating a point spread bet.*

In most football games there is a favorite and an underdog. Very occasionally there are games where the two team are completely evenly matched, but for the most part one team is favored over the other to win. With point spreads, the idea is to create an even money proposition when betting on the game. So the favorite has to win by at least a certain number of points for a wager on them to be successful, and the underdog has to lose by no more than a certain number of points for a wager on them to be successful. The bigger the gap in quality between the two teams, the bigger the point spread.

Let’s take a quick step back and talk about what the sportsbook’s goal is with any game they are offering action on. Ideally, the sportsbook wants to take the perfect amount of action (money bet) on each side of a game so that regardless of who wins, they make money. Their profit comes from taking a small percentage off of the top as a house fee for facilitating the action.

Let’s say the sportsbook has a series of bets that are all +250. You think in reality that the bets should actually be +125 and that the bet is not as big of an underdog as the sportsbook thinks. This means that you think you deserve $125 for every $100 bet that wins but the sportsbook is going to pay $250. Even though you think that the bet is still supposed to lose, you should make this bet.

*Just like the minus and plus values on the point spread, those values designate underdogs and favorites in moneyline betting. In this case, Toronto is favored at -185 (bet $185 to win $100), and Baltimore is listed as the underdog at +165 (bet $100 to win $165). In explaining the concept of moneyline betting further, it might help to view the number 100 sitting between the favorite and underdog values: +165 +100 -185*

__What does this mean for how you win a point spread bet? Glad you asked. To win a point spread bet, you pick the team that you think is going to "win" after the point spread differences are calculated in. Let's look at an example that will make this clearer. In the above chart, we see that you can bet the San Diego Chargers at -3. This means, as we already stated, that the sportsbook thinks the Chargers are the favorites and that they are going to win by three points. Here are three potential scores of the game:__

^{This is called line shopping and is an integral part of sports betting, especially with moneyline bets. Most good sports bettors will have accounts on lots of different sportsbooks so they can check the lines on every bet they are making. Whichever book has the best lines for them is where they’re going to place their bet. To be honest, with how easy it is to shop lines online, the only reason you wouldn’t is if you were too lazy and didn’t care enough about your bottom line. }

**Before actually betting or creating your draft for your fantasy football team, it’s best to take time to study the methods well and find a credible website that would give you the best forecast for NCAA Football Odds. The key to a higher probability in winning is to be able to use all the odds in correlation to each other. Once you understand how NCAA Football Odds computed, you’re on the right track to achieving your goal.**

*To calculate your potential payout, you multiply the size of your bet by the decimal. That’s it. If you want to be $10 on the Heat, you would multiply $10 by 1.65 and get $16.50. Now, you may be freaking out right now saying that in our previous example we got $6.50 and now we’re getting $16.50. The difference here is that the decimal calculation will tell you your TOTAL payout which will include the return of your original wager. You will be receiving $6.50 in profit and the $10 from your original bet.*

*‘Extra-Time’ wagers apply to 30 minutes of play according to the match officials, plus any added injury or stoppage time. However extra-time and penalty shoot-outs are not included. In ‘Extra-Time’ markets, wagers apply to the result during the extra-time period only. For the purposes of this market the score shall be deemed to be 0-0 at the start of the extra-time period.*

When two teams square up for a matchup, whether that be on the gridiron or on the basketball court, one team is typically better than the other (for whatever reason you want to believe). Since sportsbooks are in the business of making money, they tag the better team with a point spread, thus making them the "favorites" to win that specific game. Normally, the favorite has a few favorable factors working for them like playing at home or being well rested or playing a revenge game against a team that previously beat them. Every factor counts in the world of betting, and it's up to you to decide if the "favorite' can, in fact, cover the point spread.

*When it's not NFL season, BetOnline keeps on chugging along with point spreads for numerous other sports including men's + women's basketball (pro + college), along with run lines for baseball (full game + 5-inning), and they even have goal lines for several hockey leagues worldwide. BetOnline excels when it comes to betting on any sport, visit them today and give them a chance to prove it...it will not cost a cent!*

**Have you ever heard of moneyline betting? It's an American term that's traditionally associated with betting on the major US sports. These wagers are available in other parts of the world too, but they're typically referred to as win bets. The same principle applies though. When you correctly select which team will win a match, you'll get paid out at the relevant odds.**

`The level of the gambler’s profit or loss will be determined by the stake size selected for the bet, multiplied by the number of unit points above or below the gambler’s bet level. This reflects the fundamental difference between sports spread betting and fixed odds sports betting in that both the level of winnings and level of losses are not fixed and can end up being many multiples of the original stake size selected.`
