The sportsbook will sometimes move this line if they need to encourage more bets on one side of the game. Their end goal is to have the same amount of money bet on both sides of the game so that no matter who wins, they make money. For as much as they love to facilitate gambling and betting, they don’t like to leave things to chance for themselves.
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.
Money line bets are on offer on all major sports. In the NFL, baseball, the NBA and the NHL, the money line traditionally goes alongside the point spread bets – in many cases being the least popular, especially in football and basketball. In many sports there is no point spread, motor sport being a good example, so in a sport like this, the money line is the only way to bet on the outright winner. Sports with small margins of victory are also popular money line wagers – soccer being an example, where point spreads are possible, but because of the lack of goals, the money line wager is preferable (the same can apply to baseball and hockey – although puck lines and run lines are a way for the gambler to enjoy point spread betting in these).
You may be wondering how we determined which of the two teams was the favorite and which was the underdog. You may also be wondering how much you get paid out for a bet on either side of this game. If you look at the odds above (this is a screenshot from an actual online sportsbook), you’ll see that all of that information is given to you. Before the spread number of 4 ½, you’ll see a plus or minus sign. The plus sign indicates the underdog and the minus sign indicates the favorite.

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. 

The Patriots are set to take on the Rams in the greatest show on turf and money has been flowing into both sides of the Super Bowl 53 point spread. The Patriots are -3 for SB LIII according to most legal online sportsbooks but some have them listed only at -2.5. The Rams and Patriots are both offensive minded, and capable of scoring quickly; therefore, the winner will likely be whoever scores last in the game (-180). There is still no discussion of whether the roof will be open or closed at Mercedes-Benz Stadium in Atlanta, so weather may or may not play a factor here. Either way, make sure to get in your bet on the spread for Super Bowl 53, whether you choose the Patriots or Rams, before the 6:30 EST kickoff on Sunday, February 3rd.


When a betting line is listed, it will contain the moneyline and spread information. If there are two teams and there is a spread of +6 and -6, betting on the favorite, which is the – spread, the score must be greater than the underdog’s score to win. For example. The score between the Patriots and Bengals is 20 to 10. So, 20-4 is 14, which is greater than the 10 points earned by the underdog, so the bet will win.
Piggybacking on the simplicity of moneyline bets is the ease with which you can properly assess value. Now, you’ll notice that it doesn’t say “Easy to Find Value,” and that is because it’s never easy to find value in sports betting. If it were easy, everyone would be doing it for a living. What it says, though, is that it is easier to find value with moneyline bets because of the simplicity.
Oddsmakers do more than pick the winners and losers of each game. They weigh myriad factors to determine which team is favored by how many points. They set an early point spread on each game, then adjust it up or down based on betting patterns. If the Dallas Cowboys are 6-point favorites over the New York Giants, they must win by seven or more points to pay off winning bets. If you wagered on the Giants, you win your bet if New York either beats Dallas outright or loses by five points or fewer.

The point spread is essentially a handicap towards the underdog. The wager becomes "Will the favorite win by more than the point spread?" The point spread can be moved to any level to create an equal number of participants on each side of the wager. This allows a bookmaker to act as a market maker by accepting wagers on both sides of the spread. The bookmaker charges a commission, or vigorish, and acts as the counterparty for each participant. As long as the total amount wagered on each side is roughly equal, the bookmaker is unconcerned with the actual outcome; profits instead come from the commissions.
All relative events must be completed within the same day/session as listed in conjunction with the offer. Should this not be the case, bets placed on the offer will be fully refunded except for those offers whose outcomes were decided prior to the abandonment and could not possibly be changed regardless of future events, which will be settled according to the decided outcome.
To counteract this, the sportsbook decides by how many points they think the Mavericks will win. In this case, they think the Mavericks should win by 4 ½ points. On the same token, they think the Celtics should lose the game by 4 ½ points. 4 ½ points is known as the line or the spread. If you bet on the Mavericks with a spread bet, they have to win by MORE than 4 ½ points for you to win your bet. If they win by 5 points, you win. If they win by 20 points, you win. If they win by 4 points, you lose.
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.
Moneylines have a tendency to move quite a bit in both directions leading up to a game, match, or fight. It’s a delicate dance that you’re going to have to master if you want to find value and push your edges to the max. Sports betting is a profit source that is all about small edges. Finding and being able to capitalize on these small edges is the key to being profitable long-term.
The second way is “eyeballing it.” If two teams play 10 times, how many times do you think a certain team is going to win? If you say they are going to win 6 times, then you think they are going to win 60% (6/10) times. Looking at it as a series of multiple games makes it a lot simpler for you to grasp and predict. Then, you just convert that number to a percentage and compare it with the implied probabilities offered at the sportsbooks. If there is value, go for it.
As you can see, the public seems to think that Florida is going to win this game by more than seven points. If the game started now, the sportsbook would stand to lose a lot of money if Florida did in fact win by more than seven points. They would stand to make a lot of money if Florida lost or won by less than seven points. Regardless of how the sportsbook thinks the game will go, they are not in the business of gambling. They want to guarantee profit as often as they can.
You should already know that the Eagles are the favorite to win and that you should expect less than even money on a correct pick here. You should also know that the Falcons are the favorite, and you should expect better than even money on a correct pick here. Having this in mind every time before you start your calculations will protect you from making a mistake and calculating the completely wrong direction.
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.
Although the examples from above are in $100 increments, you don’t actually have to bet those exact amounts. That’s just how the odds are set up so that everyone is on the same page. With a quick glance at the numbers, you can tell who is the favorite, who is the underdog and what type of payout you can expect on each. You’re free to bet $5, $500 or whatever amount fits your budget. If you want to find out the specific betting limits for each option, browse through the betting sites rating guide in order to find the sportsbook that better fits your minimum and maximum limits.

It’s common knowledge among bettors that the online gambling industry pays close attention to Las Vegas Sports Consultants, a private company that handles the odds for casinos and newspapers. But the totals I set have to reflect our customers’ preferences for betting the over or under on certain teams in certain situations. Also, because LVSC lines are published early, I have to keep on top of injuries and potential changes in coaching strategy leading up to the game in question before I release any totals. This is doubly important in basketball, where pace determines how many shots will be taken in 48 minutes.
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).
Sportsbooks will use a variety of methods to set their line on a game. Some firms will use computer simulations, some will use a form of power ratings, some will use an experienced team to set the line – some may even use a combination of all three. Other books may even wait to see where their rivals set their lines before dipping their toe in the water themselves.
The term moneyline is actually somewhat misused in sports betting as it really just means a type of odds format. Technically, it is a way to represent the odds/payouts for a win bet, but we’re not going to split hairs. What we’d like to point out is that the odds on each participant in a sporting contest can be listed in one of three different formats.

From time to time, DraftKings might decide to publish offerings referring either to the single performance of a participant or team; or offerings which combine the potential outcomes of 2 or more participants at higher odds than those normally available, also known as ‘Bet of the Day’. DraftKings reserves the right to withdraw such offers, edit the respective odds, and effect any further changes that might deem necessary at its sole discretion.

You may have heard the term “covering the spread” or the phrase “betting against the spread.” This means that if the favorite team wins an event with the point spread taken into account or that the underdog team wins with additional points, they have covered the spread. If the Packers win that game by more than 7 points, they have covered the spread.
