As we mentioned in the close of the last section, sportsbooks try their best to get the same amount of total money bet on both sides of a game. If they can accomplish this, then they are guaranteed to make a profit no matter who wins or loses the game. The way a sportsbook goes about doing this is by manipulating the point spread to make the less bet side more enticing.

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.
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.
When you’re looking at over under bets, what you need to know is that that’s the combined score of the two teams for a game. In this case, it doesn’t matter who wins the game. All that matters is the final score. For example: let’s say that the New York Yankees are playing the Boston Red Sox and the total is 9.5. It doesn’t matter who wins the game but if the two teams combine for a total score of eight runs, say with a final score of Boston winning 5-3, then the game goes under. Or if the two teams combined for 10 runs – no matter who wins – then the game goes over. So when you’re looking at the odds and you see a total next to the moneyline or point spread, that tells you the over-under that is set for the game and you have to decide whether it will go over that set amount or under.

Feel free to play around with exactly how much to bet per wager. We just wanted to show you that making a guaranteed profit is doable. Since it's possible to claim bonuses at a number of different sites as a new customer, and since many sites offer a reload bonus, this strategy is repeatable. The most important thing to remember is this; only bet with reputable sites, like any of the ones we recommend.
For example, imagine a game where the odds were -550 for the favorite and +450 for the underdog. A bettor shopping around for lines might be delighted to see the same favorite offered at -490 and enthusiastically back the team at those odds simply because those are the best odds available. However, if we removed the vig from -550 and +450, we'd see that the fair odds are actually -466 and +466. So, placing a wager at odds of -490 doesn't actually offer any value.
Had you initially bet $100 on the Mavericks, you would walk away with a profit of $90.91. Now, if you bet on the Mavericks, you will see a profit of only $76.92. On the other side of the bet, an earlier bet on the Magic would have paid you $105. Now that same $100 bet will get you $125 if the Magic win the game. Ideally, this will entice more people to bet on the Magic and the action on the Mavericks to slow down.
You can also bet straight winners and losers -- with no point spreads involved -- with money line wagers. When there is a minus number you bet that amount to win $100 in profit. When there is a plus number, that is your winning profit for every $100 wagered. So if the Cowboys have a money line of -250, you would have to bet $250 on them to win $100 in profit on any Dallas victory. If the Giants had a money line of +150, you would win $150 in profit with a winning $100 bet. If a money line is posted as even, you would win a $100 profit on a $100 winning bet.
Used in high-scoring sports like NFL and NBA, the point spread is a handicap that is placed on the favorite team in terms of points for betting purposes. If 10 points favor the Broncos over the Seahawks the point spread is 10. The Broncos must win the game by 11 or more points for you to win your wager. If you’ve made your bet on the Seahawks, you’ll win your bet if your team wins the game or losses by nine points or less. If the Broncos manage to win by exactly 10 points then the bet will be a tie.
The optimal situation for bookmakers is to set odds that will attract an equal amount of money on both sides, thus limiting their exposure to any one particular result. To further explain, consider two people make a bet on each side of a game without a bookmaker. Each risks $110, meaning there is $220 to be won. The winner of that bet will receive all $220. However, if he had made that $110 bet through a bookmaker he would have only won $100 because of the vig. In a perfect world if all bookmaker action was balanced, they would be guaranteed a nice profit because of the vig.
You could even take it a step further and take the next rectangle down and bet Liverpool +1. This means that Liverpool can tie or win by any amount of goals and you win your bet. As Liverpool is a huge favorite, you won't be paid very well at all for this bet, but you can still turn a profit when you are right. You would be paid at 1 to 10 which means you would get $1 for every $10 you bet. If you bet $100, you would get a $10 profit on this bet.
Spreads are frequently, though not always, specified in half-point fractions to eliminate the possibility of a tie, known as a push. In the event of a push, the game is considered no action, and no money is won or lost. However, this is not a desirable outcome for the sports book, as they are forced to refund every bet, and although both the book and its bettors will be even, if the cost of overhead is taken into account, the book has actually lost money by taking bets on the event. Sports books are generally permitted to state "ties win" or "ties lose" to avoid the necessity of refunding every bet.

The two results above are the no-vig probabilities. If you're sharp, you'll notice that adding 68.57% and 31.43% up together will give you 100%. The extra 2.95% has been removed, so there's no more vig. We can now go to our odds converter and enter 68.57% into the implied probability field. This will give us moneyline odds of -218. If we enter 31.43%, we'll get moneyline odds of +218. The original moneyline market of the Celtics at -240 and the Grizzlies at +210 therefore has no-vig odds of the Celtics at -218 and the Grizzlies at +218.

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.
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.
Where people seem to get confused with moneyline bets is with how they are presented and how they pay out. While the criteria to win a moneyline bet will never change, the amount you win and how the bet is presented will change. Don’t worry, though. It’s easy to understand if it’s presented to you properly. We are going to cover this thoroughly in the coming sections. You’ll be a moneyline expert ready to crush the books when you get done with this guide.
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.

Having a choice between the money line and the point spread gives the bettor more options. Consider a scenario where there is a strong favorite for a game. You might want to guarantee a smaller return by betting on the favorite to win on the money line – or you might want to almost double your money by betting on that team to not only win, but win by more than a certain margin. Conversely by backing the dog, on the money line you’ll receive a better return for your money but by backing the same team against the spread you have the insurance of still being able to win even if the team don’t.

A quick word on that annoying half point in the point spread – most lines you’ll come across will use half points, but it’s not standard practice across the board. When you see a line with a full number instead of a number with a half point, your wager could end up as a push. In our example, if the line were 7 instead of 7.5 and the final difference in points was exactly 7, your wager is returned to you, and neither you nor the book makes money.
Another way to beat football point spreads is to shop for off market prices. For example, let's say you're shopping online betting sites and see every site is offering Vikings +7.0. Then, you stumble upon one site that's offering +7.5. There's a good chance that this is a +EV wager, simply because it is out of sync with every other site. Please note that this strategy isn't quite the same as simply shopping for the best lines. Here, you're specifically looking for wagers that are +EV because they're against the market.
Now Arkansas can lose by up to eight points, and you can still win a bet on Arkansas. As the Arkansas line gets more appealing, more people will start to bet that side. The sportsbook will continue to manipulate the line this way up until game time to try and get the bets as even as possible. While they won't be perfect about it, they can usually get it close enough in most situations. It's also important to note that the line will sometimes shift by half points and it's also capable of shifting back in the other direction if too much money comes in on the other side.

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.
Below we have also put together an infographic explaining all of the information on this page. This is a useful tool for someone who wants to see a visual explanation of how to calculate your payouts when using moneyline odds in your betting. You can save this graphic for your own personal use or use the embed feature to put it up and share with others.

The most important takeaway is the actual pointspread, which is seven points in this example. The plus sign is always in front of the spread for the underdog and the minus sign is used to signify the favorite. Next to the pointspread in this example is (-110). This number reflects the actual commission (or juice) that the sportsbook is charging to book this bet. If you wager $100 on New England as the favorite and the Patriots go on to win my more than seven points, you would win $100. If they won by fewer than seven points or lost the game outright, you would owe this betting outlet $110. If New England wins by exactly seven points, the bet is considered to be a PUSH and no money exchanges hands. You only pay the 10 percent commission on losing bets.

One important assumption is that to be credited with a win, either team only needs to win by the minimum of the rules of the game, without regard to the margin of victory. This implies that teams in a winning position will not necessarily try to extend their margin—and more importantly, each team is only playing to win rather than to beat the point spread. This assumption does not necessarily hold in all situations. For example, at the end of a season, the total points scored by a team can affect future events such as playoff seeding and positioning for the amateur draft, and teams may "run up" the score in such situations. In virtually all sports, players and other on-field contributors are forbidden from being involved in sports betting and thus have no incentive to consider the point spread during play; any attempt to manipulate the outcome of a game for gambling purposes would be considered match fixing, and the penalty is typically a lifetime banishment from the sport, such is the lack of tolerance for gambling in sport.
