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.
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.
Another form of futures betting involves the over/under on the number of games a particular team will win in the regular season. This type of wager is typically found on pro football and major league baseball, and sometimes on pro basketball. For example, the over/under on the Yankees may be 93 wins. If the Yankees go on to win 94 or more games, the "over" is a winner. If they win 92 or fewer games, the "under" is a winner. If they win exactly 93, the bet is a push and tickets are refunded.
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.
If the public comes out and bets really hard on one side, the line is going to move a lot making the odds worse on that side and a lot better on the other side. If you’re planning to bet against the public, you should wait to bet until the line moves as far as you think it is going to. Be careful, though, if you wait too long and some big money bettors bet, they can move the line back.
"Winning Margin" (aka Result Betting) is where it is possible to bet on the final result of a game or event and select the correct ‘band’ of points between the winning team and losing team. For example, if you think the Patriots will win, but the game will be close, pick the New England Patriots 1-6 Points Winning Margin (where the Patriots winning by 1, 2, 3, 4, 5, or 6 points results in a winning selection).
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.
For example, in a cricket match a sports spread betting firm may list the spread of a team’s predicted runs at 340 – 350. The gambler can elect to ‘buy’ at 350 if they think the team will score more than 350 runs in total, or sell at 340 if they think the team will score less than 340. If the gambler elects to buy at 350 and the team scores 400 runs in total, the gambler will have won 50 unit points multiplied by their initial stake. But if the team only scores 300 runs then the gambler will have lost 50 unit points multiplied by their initial stake.
Moneyline bets will move the line based on the amount of money coming in on each side of the bet. It has nothing to do with who the sportsbook really thinks is going to win the game and everything to do with that delicate dance of getting the right money on both sides. For example, let’s say that the line for the Magic and Mavericks game is the following:
For example, let’s say you’re thinking about betting on something that is -3500. You are almost 100% sure that you’re going to win this bet. If you bet $100 on this bet, you’re going to see a profit of $2.86. Again, this might be worth it to you. An almost 3% return on a sure thing might be something that you’re interested in. However, if you’re looking to make any meaningful profit, you’re going to have to risk a lot of money. To win $100, you’re going to have to risk $3500.

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 spread on offer will refer to the betting firm’s prediction on the range of a final outcome for a particular occurrence in a sports event e.g. the total number of goals to be scored in a football match, the number of runs to be scored by a team in a cricket match or the number of lengths between the winner and second-placed finisher in a horse race.
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.
You don’t have layers of complexity to fight through to see if your prediction is a positive expected value move (one that is going to make you money). With some simple mathematical calculations, you can figure out whether or not there is value in a bet. Even if you don’t like math and would prefer not to use it when assessing value and making your picks, it’s still much easier to “eyeball” value with moneyline bets because of the simplicity.
"Winning Margin" (aka Result Betting) is where it is possible to bet on the final result of a game or event and select the correct ‘band’ of points between the winning team and losing team. For example, if you think the Patriots will win, but the game will be close, pick the New England Patriots 1-6 Points Winning Margin (where the Patriots winning by 1, 2, 3, 4, 5, or 6 points results in a winning selection).
Sports betting is not just about being able to pick out the winner and loser of a game. Because of the various different bet types, there is a lot of different strategies that goes into how you approach them. Point spread bets are no different. One of the biggest tips we can offer is to make sure that you fully understand what you are betting on. A great pick is only great if you actually put your money behind it correctly. Thankfully, this guide should have you fully prepared for that.
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.

We’ve already covered that a moneyline bet is easy to make and is the most popular type of sports bet for beginners and for professional bettors. Now let’s talk about exactly what it is. A moneyline bet is a sports betting wager on which team or person will win a game or sporting contest. Simple as that. When you make a moneyline wager, you are betting on who will win a contest. It doesn’t matter how they win, by how many points, goals, or runs they win, or how long it takes them to win. All that matters to win a moneyline bet is that the team or person you bet on is victorious.
This may sound confusing, but spread betting is one of the easiest forms of sports betting offered. It also offers better odds when betting on the favorite team and the normal odds are 10/11 or -110. When one chooses to bet on the underdog that team does not have to win, they just have to cover the spread. Spread betting is pretty simple and it allows punters to enjoy an exciting form of betting that can lead to some significant wins.
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.
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.
There's another reason to bet the underdogs on the moneyline as well. If your handicapping has made you feel very strongly that a poor team is due for a big win then the moneyline allows you to profit much more handsomely from your conclusion than a point spread bet does. The moneyline, then, is a powerful situational tool for people who closely follow the NBA.
For example, in a cricket match a sports spread betting firm may list the spread of a team’s predicted runs at 340 – 350. The gambler can elect to ‘buy’ at 350 if they think the team will score more than 350 runs in total, or sell at 340 if they think the team will score less than 340. If the gambler elects to buy at 350 and the team scores 400 runs in total, the gambler will have won 50 unit points multiplied by their initial stake. But if the team only scores 300 runs then the gambler will have lost 50 unit points multiplied by their initial stake.
Apply the spread. In point-spread betting, the actual final score of the game is only the starting point. Say Chicago beats Detroit 24-17. Because Chicago was the favorite, you subtract the point spread from its final score. That's the purpose of the minus sign in the spread. The spread was 6, so you take 6 points away from Chicago's point total, giving you an "adjusted" score of Chicago 18, Detroit 17. If you'd bet on Chicago, you'd have won the bet. Now, say Chicago won the game 20-17. Subtracting the 6 points from Chicago's total gives you a final score of Detroit 17, Chicago 14. If you'd bet on Chicago, you'd have lost.

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.


"Half time/Full time" is where it is possible to bet on the result in half time as well as the final outcome of an event. For example, if at half time the score is 45-45 and the match ends 103-101, the winning outcome is Tie / Away Team (the team scoring 103). The bet is void if the regular time of the match is played in a different time format than those listed in the bet . For example, in baseball, half time is defined as the first 5 innings of a game.
