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.
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.
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.
Betting “against the spread” (ATS) just means you’re betting on the point spread in a particular matchup as opposed to the moneyline, or some other type of wager. Bettors often use a team’s ATS record to gauge its performance against the spread. For example, the New England Patriots were 11-5 ATS in the 2017 regular season, meaning they covered the posted point spread 11 times, and failed to cover five times.

As you might guess, you’re mainly going to see American odds in American sportsbooks. The other two formats are much more prominent in Europe and Asia. If you’re betting online, most sportsbooks give you the ability to change all of the odds on the site into the format that you prefer. No format is different regarding payouts; it’s just a different way of presenting the information.
Because the Blue Jays are favored, the sportsbook needs you to risk more to bet on them. After all, they should win this game. So wagering on baseball favorites with moneylines calls for you to risk a certain number ($185 based on -185) in order to win $100. On the other side, the sportsbook is also willing to reward you for taking the underdog, so they give you an incentive to bet on the Orioles. In this case, you would risk $100 in order to win $165 (+165) on Baltimore.
The second number in our example (-110 for both teams) tells you how much you have to wager in order to win $100. It’s an easy way to calculate how much you’ll win if your bet pays off, presented in units of $100 at a time for simplicity’s sake. Most of the time, these two numbers will be the same, because oddsmakers want to set lines so that they get as much action on the underdog as on the favorite, guaranteeing them a profit. If a book gets a single bet of $110 (by a customer hoping to win $100) on the Cowboys and a single bet of $110 on the Giants, it will have taken in $220, but will only have to pay back $210 to whichever customer wins the bet. That’s a guaranteed profit of $10, and since sportsbooks take far more than a single bet in either direction, they stand to earn that seemingly small amount of profit many times over. The $10 difference between what you wager and what you win is known as juice or vig in the sports betting industry, and it’s the way books earn their bread and butter.
Rotation numbers are standard from sportsbook to sportsbook. The number becomes a way to refer to the game and team without mentioning the teams name. It’s a sort of shorthand. Also, the rotation number allows each book to list the games in the same order—numerically. It is, in essence, a way to keep all of the games that are posted each day and throughout the week organized. That makes it easy for the bettor and the bookie.
One of the most basic concepts when it comes to betting on sports, especially football and basketball is the pointspread. Even people that do not bet on sports understand what it means when they read or hear that New England is a seven-point favorite against Miami. While reading a pointspread and understanding what they mean is a very basic sports betting concept, there is still more to these numbers than meets the eye.
In addition to the spread bet, a very common "side bet" on an event is the total (commonly called the over/under or O/U) bet. This is a bet on the total number of points scored by both teams. Suppose team A is playing team B and the total is set at 44.5 points. If the final score is team A 24, team B 17, the total is 41 and bettors who took the under will win. If the final score is team A 30, team B 31, the total is 61 and bettors who took the over will win. The total is popular because it allows gamblers to bet on their overall perception of the game (e.g., a high-scoring offensive show or a defensive battle) without needing to pick the actual winner.
Let’s start with the basics: what do sports bettors mean when they talk about a ‘line?’ The word line, in the language of a sportsbook, can refer to either the odds and/or a point spread in any sports contest. Let’s take a look at an imaginary line the way you’d read it off the board sitting in a Vegas sports betting lounge or on the screen at your online book. Let’s imagine a game between the New York Giants and the Dallas Cowboys. Your book’s NFL betting line might look something like this:

The number that follows the plus or minus sign will indicate how big of a favorite or an underdog the team is. The larger the number is, the bigger the favorite or the underdog the team is. For example, a team that is -300 is a bigger favorite than a team that is -150. A team that is +240 is a bigger underdog than a team that is +130. Remember, this is not the sportsbook’s actual prediction on who they think will win; it’s in relation to the money that has been bet on the game. It is more depictive of who the betting public thinks is going to win the game.
This used to be impossible or extremely time-consuming when only land based sportsbooks and casinos existed. You would have to drive hundreds of miles if you wanted to get to another casino and then hope they still had the different line. This would cost you travel money as well as time. Online sportsbooks make this extremely easy now. You can check several sportsbooks lines on a game within a matter of seconds or minutes. It doesn't cost you any additional money, just a few minutes of your time and can have a huge impact on the outcome of your bets.
The main goal for each sportsbook is to set the best line possible in order to create even action on both sides of the game. In a perfect world, the book would have 50 percent of the handle come in on the favorite and 50 percent of the action come in on the underdog. If this happens, the sportsbook would be guaranteed a profit because of the 10 percent vig they charge on most point spread wagers. When a book has serious one-sided action, they will attempt to counter that by moving the line in the direction that's taking the most money and try to entice bettors into betting on the other side.

If your sports betting experience consists mostly of office pools during March Madness or a casual wager between you and a friend while you watch the Super Bowl, the transition to serious sports betting means learning how to read betting lines. The biggest difference between making the kind of casual bets mentioned above and placing wagers with online sportsbooks or at brick-and-mortar bookshops is the use of sports betting lines. Casual wagers usually involve each person in the bet picking one team to win, then wagering an equal amount, say $20 or $30. Professional bookmakers, online sports betting exchanges, and sports betting facilities in casinos have a more complex system for offering wagers on sporting events, in part to ensure profit on the part of the book, and in part to present a standardized representation of 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.

Straight bet - Amid all the fancy and lucrative-looking bets that are available, never lose sight of the value in a standard straight bet. You probably should learn and practice this bet often before learning any others, and it should be noted that people who bet for a living or a large portion of their income place straight bets almost exclusively.
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.
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.
A point spread - Lets take, for a hypothetical situation on one of the types of football bets (using the point spread), that the Kansas City Chiefs were visiting the Detroit Lions and Detroit was established as a six-point favorite at game time, which is commonly written as Detroit -6. Kansas City would be the underdog and displayed as Kansas City +6. If you bet the favorite, Detroit has to win by more than six points to win your bet. Remember, the Lions are favored by six points, so we subtract six points from their final score on a spread bet. If Detroit were to win 27-20, Lions bettors would win their wager. If the Chiefs were to win the game by any score and you picked the Chiefs you would win not including the extra six points. If the Lions were to win, 20-14, it would be exactly six and a push, so you would get your money back.
In the brackets after the last two games, you will see the odds associated with each of the bets. Let's say we made our earlier example bet of the Chargers -3 and the final score of the game was Chargers 21, Cowboys 14. Looking at this, we already know that we won our bet, but just how much money are we going to get paid? For this bet, we will get paid even money because that is what is posted in the parenthesis. This means that if we bet $100, we will profit $100 for winning our bet.
The reason why you will typically see a (-110) line next to a point spread is simple. This is the commision in which the sportsbooks charge for you to place your wager. This is how the casino makes their money. Think of it as a commission. You make a bet, they charge 10% for you to do so. Bookmakers call this “Vigorous or Vig” it’s also known as the “Joice”

It is a very good idea to shop around to find the best line when you are betting on sports. Books may offer slightly different lines, and you might be able to gain a point or half a point in your favor on certain markets. Consider an NBA game between the Heat and the Lakers – one firm has the Heat 9.5 point favorites and another have the Heat as 8.5 point favorites. You back the Heat with the second firm and they win by exactly nine points. Here you’ve gone from a loss to a win simply by shopping around, and in the long run this will make a big difference to your bottom line.
Bookmakers use odds to even out the bets, getting gamblers to wager on both sides of the line by leveling the playing field. Although there is overall parity in the NFL, there are teams that are haves and others that are have-nots. Indianapolis is still superior to Cincinnati but when they play each other the bookies have to get about half of the bettors to put cash on the Bengals. This covers the sportsbooks ensuring they’ll make a decent amount of cash on just about every game.
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.
In an effort to have equal money on both sides of a wager, the sportsbook operator will move the point spread to attract money on the side that customers aren’t betting on. The odds for a point spread might change before the actual point spread. There are certain point spread numbers, like 3 and 7 in football, the sportsbook operators would like to avoid moving away from since they final score margin falls on these two numbers most often.
