Linemakers who work for the sportsbooks must put out lines that will entice the "favorite" bettors to lay the points and take the favorite or entice the underdog bettors to take the points with the underdog. Because each sportsbook is operated under their own rules, guidelines and stipulations, they are free to put out whatever line they feel is competitive and charge whatever vig they want to based on how much action that specific line is taking.
Armed with the knowledge of how to remove vig, it's now possible to prevent yourself from making the same mistakes that the majority of bettors make. Most bettors understand the importance of line shopping (i.e. comparing the lines and odds at different bookmakers and betting sites). However, if they fail to also understand how moneylines and vig work, then they're probably going to make wagers where they think there's positive expected value (+EV), even though there's not.
The house vigorish - and your chances of winning - get worse with the more teams you add. So while some sportsbooks will let you place a 15-teamer with astronomical odds, you probably have a better chance of being struck by lighting - twice - before winning one. You are much better off sticking to two-team parlays exclusively, if you insist on taking poor odds and placing parlay wagers.
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.
The point spread - also called "the line" or "the spread" - is used as a margin to handicap the favorite team. For betting purposes, the oddsmaker predicts that the favored team will win by a certain number of points. This number of points is the point spread. The favorite is always indicated by a minus sign (e.g. -5.5) and the underdog by a plus sign (e.g.+5.5). If you bet on the favorite, you win your bet if the favorite wins AND their margin of victory is greater than the point spread. If you bet on the underdog, you win if the underdog wins, ties, or if the favored team wins but fails to exceed the point spread. It is standard for point spread bets in most sports that you wager $110 to win $100.
Sports spread betting began in the United Kingdom in the late 1980s to offer an alternative form of sports wagering to traditional fixed odds, or fixed-risk, betting. With fixed odds betting, a gambler places a fixed-risk stake on stated fractional or decimal odds on the outcome of a sporting event that would give a known return for that outcome occurring or a known loss if that outcome doesn’t occur (the initial stake). With sports spread betting, gamblers are instead betting on whether a specified outcome in a sports event will end up being above or below a ‘spread’ offered by a sports spread betting firm, with profits or losses determined by how much above or below the spread the final outcome finishes at.

Betting against the spread - In the sports betting industry the acronym ATS is used to label a team's record when betting against the spread. ATS records are a valuable tool in sports handicapping. A team may be playing great straight-up, winning a lot of games but at the same time they could have a dreadful ATS record because they are overvalued by the general public and the oddsmakers. And, conversely, a team could be losing a lot of games but playing in a lot of close games as underdogs and have a good ATS record going.
It is important to note the difference between spreads in sports wagering in the U.S. and sports spread betting in the UK. In the U.S. betting on the spread is effectively still a fixed risk bet on a line offered by the bookmaker with a known return if the gambler correctly bets with either the underdog or the favourite on the line offered and a known loss if the gambler incorrectly bets on the line. In the UK betting above or below the spread does not have a known final profits or loss, with these figures determined by the number of unit points the level of the final outcome ends up being either above or below the spread, multiplied by the stake chosen by the gambler.
Two possibilities existed for Seahawks backers at this point – either the team would win the game by at least three points or not. There was no possibility for a push, thanks to the use of a half-point. It’s impossible to score a half-point in football, so thanks to the magic of rounding, there’s no room for a tie outcome. Those who backed the Patriots were looking at two possible outcomes, too – either New England would pull off the upset or they would lose by just a point or two. Both would turn out in a win.
Obviously, the first three letters on the top two lines of the three-line package of symbols represents a team in the game you’re wagering on; NYG stands for the New York Giants, while DAL stands for the Dallas Cowboys. The number next to each team’s name is known as the spread or the point spread. Wagers on the point spread are among the most popular sports wagers in the world. The reason this wager is popular is that it doesn’t matter which team wins or loses; what matters is the amount of points the teams score, and whether or not the team you place your money on beats the difference in points (the ‘spread’) or not.
These are the handicap bets that we have already talked about. These are your straightforward bets that pay out according to the spread and odds posted. Draws are treated as a loss with this format. If you just scrolled to this section first, scroll up and read the general section about handicap bets because this type is addressed extensively with some great examples there.
If you've never set foot in an actual sportsbook before or logged into an online sportsbook, the chances of you getting overwhelmed when you actually do is very high. In an actual Las Vegas sportsbook, there is typically a lot of commotion and the odds and lines are displayed on a massive digital board for everyone to see. When a novice sports bettor looks at the massive digital signage, they will see a bunch of numbers, both positive and negative, some two digits, some three digits. They also won't have a clue what any of it means. The same can be said for the online sportsbooks. It looks like a massive spreadsheet with negative and positive numbers beside each teams' name.
They do this by manipulating the lines to entice action where they need it. If they have too much action coming in on one team, they will adjust the lines to pay out less for that team to deter more bets. At the same time, they will adjust the line for the other team to pay out more to entice more action on that side. This dance continues until the game starts to try and get the correct amount of money on each side of the contest.
The key here is to target the point spread five and seven, because these are virtually tied as the most common margins of victory. It's important to recognize that most betting sites are only willing to sell 2 or 3 half points for 10 cents each, after which point they start charging more. Some sites sell up to four half points at this price though.
Proline will set a point spread for each game of either -0.5 / +.05, -1.0 / +1.0, or -1.5 / +1.5. If you choose -0.5 the team must win by 1 goal or more to win your wager. If you choose +0.5 your team must win or tie the game. Note that OLG Proline includes the shoot-out for point spreads so there are never any ties for the -0.5 / +0.5 spreads.  If you choose the -1.0 spread your team must win by 2 or more goals to win the bet. If they win by 1 goal exactly it is a push. If you choose the +1.0 spread your team must win the game by 1 or more goals. If they lose by 1 goal it is a push. If you choose the -1.5 spread your team must win by 2 or more goals. If you choose the +1.5 spread your team must win the game, tie, or lose by 1 goal to win the bet.
This also comes into play on games that you think the line is correct. For example, let's say you think the line of Florida -7 is correct, so you elect not to bet it because there is no value. This doesn't mean you should never look at this game again. If the line happens to shift in either direction, you can make a bet that has value. If the line moves to Florida -6, you place a bet on Florida because you originally thought they would win by seven. If the line moves to Florida -8, then you place a bet on Arkansas at +8 because you originally thought Florida would win by seven and Arkansas would lose by seven. The next strategy tip is a good idea to help you be ready for these situations.
In the United States, most bookmakers use the moneyline format to express the odds they offer for wagers. Thus, moneyline odds are also commonly referred to as American odds. They can be either a positive number or a negative number. A positive number shows how much profit a winning wager of $100 would make, while a negative number shows how much needs to be staked to win $100.
If you are able to interpret NFL odds and know what the various terms mean, such as the rotation number, point spread, moneyline and over/under, you’ll have a basic understanding on what you are betting. Prior to wagering make sure you see our NFL odds page, which carries all the latest odds from the top online sportsbooks. Remember that the odds makers are attempting to even the out the bets on each game. The sports bettor has to analyze each game and the odds and make their bets accordingly in order to win cash.
A point spread (or line) is a tool used by sportsbooks to attract wagers on both sides of a game. The line is most commonly used in football and basketball games. Because it’s rare for two teams in a pro sports game to be completely evenly-matched, one team will have an advantage, another will be seen as the underdog. The point spread is the handicap offered to the underdog to level the playing field, so to speak.
If all the money at one sportsbook comes in on Team A and all the money comes into a second sportsbook on Team B, they’re both going to adjust their lines accordingly to what is going on in their book. This means that if you want to bet on Team A, you should go to the second sportsbook where the line will be great. If you want to be on Team B, you should go to the first sportsbook where the line will be better.
Since draws are more common in soccer, most soccer markets offer 3-way spreads. When making a Soccer Spread wager, the team you wager on must cover/beat the goal spread. This means that the favored team must win by more than the outlined number of goals or the underdog will receive that number of goals as a head start. If you wager on the spread draw, you are wagering that the game will end in a draw when the spread value is applied to home team. (The team displayed first)
Betting against the spread - In the sports betting industry the acronym ATS is used to label a team's record when betting against the spread. ATS records are a valuable tool in sports handicapping.

A Parlay is a wager which combines several legs in a wager where the winnings from each selection roll onto the next. For a Parlay to be successful, all individual legs in the Parlay need to be winning selections. In the event of a tie in one of your selections in a parlay, the parlay is reduced to the next lowest number of teams. For example, if you have a 4 team parlay and one of the selections is a tie (only on 2 way markets), the leg would be considered a "push". In this instance, the 4 team parlay would then become a 3 team parlay and would be settled at reduced odds to reflect a winning 3 team parlay.
If the implied probability says that you have to win a bet 40% of the time to break even, and you think you’re likely to win the bet 45% of the time, then there is value in the bet. Remember, the sportsbook pays you more the less likely something is to happen. This means you’ll be getting paid as if the bet is only going to hit 40% of the time (more money), but the bet actually hits 45% of the time if you are right.
To help get you started, we’ve broken down the most popular and the need to know NBA bet types below. Make sure you take the time to read through each of these and figure out how they might play a role in your betting strategy. Remember, you are not required to use all of these bets.

For beginners, the moneyline bet on an underdog is a great choice as it will allow bettors to win 50% of the bets and still earn a profit. Each of these bets have benefits and drawbacks. With moneylines, punter shave the appeal of betting on a winning side. This is a great choice for die-hard fans. Many people find it more appealing to bet on a winner of a game instead of betting on the end score of the game. Spread betting does offer some nice benefits. They are simple yes or no bets. Either the team covers the spread or they don’t. However, moneyline bets typically offer the chance to win more than is bet, so these are often the choice for many bettors online.

Having set the point spread, this is the point where the gambling public can influence the line. You might have noticed that a line five days before a game might look very different to the line an hour before the kickoff. Barring some major line-up changes due to injuries or suspensions, the line will most likely be moved by weight of money. If the majority of money is coming in on one side of the point spread, the book will move the line to make the bet a little less attractive, which will help them level the book up somewhat.
The betting public as a whole is not very smart. There is a reason it is such a lucrative business to be in for the sportsbooks. The public loves to bet popular teams, great story lines, and trends that don't have a lot of merits. If you think that the public is going to bet a lot and shift the line more in your favor, just wait. In these situations, the worst that might happen is the line doesn't move, and you then take the bet right before the game at the original line that you still thought had value. Yes, there is a possibility of the point spread moving the other direction. If this happens, you just don't make a bet on this game and wait for the next one.
A common mistake that new bettors will do is to bet every single game. Unfortunately, this is not a winning strategy no matter how sharp you are. Stick to betting the games where you actually see value. Here's what we mean by value. Let's say in our earlier example that you agree with the sportsbook that the Florida Gators should win the game by seven. You should not bet this game then no matter what if the line is -7. If you're right, the best you can do is tie on your bet. When you pick a side, you're basically going to be guessing and flipping a coin. Theoretically, you'll win as many times as you lose, but you'll be paying the house percentage every single bet and slowly bleeding your money and profits away.
When wagering on a driver matchup, both drivers involved must start the race (cross the finish line) otherwise the wager is "No Action" and the money is refunded. In a case where the starting driver is replaced during the race with another driver from the same team (same car), the position the new driver finishes in will be awarded to the original driver. This holds for wagering on win odds and driver matchups.
We go in depth on this in the advanced guide on understanding value that we referenced earlier, but we will give you a brief intro on it here. If you’re able to calculate the percentage chance that you have to win in order to break even, and you can figure out the percentage chance that you think you’re going to win the bet, you can figure out very quickly if there is value.
Settlement of bets which make reference to terms such as "decisive goal" will be settled based on the scorer of the goal that at the end of the match/tie,) proves to be the one that has produced an unassailable lead, following which any further goals would prove to be irrelevant towards the final outcome. For a bet to be settled as "YES", the listed player's team must be declared the winner of that particular match or progressing to the next round or winning the competition. Goals scored in Regular Time and Extra Time count but Penalty Shoot outs do not.
Let’s say you decide to bet $100 on the Packers to win by more 7 points and the final score is Packers 30, Seahawks 21.  The Packers have won by 9 points, meaning they’ve covered the spread, and you’ve won the bet. The -110 means that your $100 bet will win you a total of $190. That total includes your original bet amount, so your total profit is $90.
