This is a huge difference. The potential profit on the moneyline wager ($143) is over 40% greater than that of the point spread wager ($100). You're a little less likely to win, as there is a chance that Seattle would lose by one or two points, but there's a more than fair chance that if they did cover they would actually win the match. And, of course, if they lost by three or more then you'd have lost either way.

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.
Here’s a less extreme example. Let’s say that Fighter A is fighting Fighter B and you think that Fighter A is going to annihilate Fighter b. Like you don’t even think it’s going to be close. Let’s say you decide that you would be willing to bet even if the odds were -400 on Fighter A. You’d only be getting $25 back on your bet, but that’s what you think is fair.

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.
Understand that negative odds indicate how much money your must spend to make $100. When betting on the favorite, you take less risk, and thus earn less. When betting on a favorite, the moneyline is the amount of money you need to spend to make $100 profit. In the previous example, in order to make $100 of profit betting for the Cowboys, you would need to spend $135. Like positive odds, you earn back your bet when winning.

You see, people too frequently get caught up on their win-loss rate, which actually has no real effect on their bottom line. You can win more bets than you lose and still be losing money. On the other side of things, you can lose more bets than you win and be wildly profitable at sports betting. It all comes down to successfully finding value and pouncing on it when you see it.
With NFL odds the over/under can vary but usually it’s somewhere between 35 and 47 points. Let’s say in the Colts and Bengals game that the total is posted at 37.5. If Indy scores 27 and Cincy gets 13 points, the total would be at 40 and the over would win. But if the Colts rack up 35, and they shut out the Bengals, the total of 35 would be under.

Technically, probability should always be a number between 0 and 1. It's often expressed as a percentage though, which makes things easier for the purposes of betting. 0.7059 converted into a percentage (i.e. multiplied by 100) gives us 70.59%. What this means is that the odds suggest the Celtics have a 70.59% chance of winning. If we believe the Celtics have an even greater chance of winning, then we should back them at odds of -240.


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.
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.

For example, if you’re betting on teams A, B, and C to win outright, you’ll have two round robin options available. Your By 2’s option includes all possible 2-team parlays for these three wagers (A+B, B+C, and A+C). And your By 3’s option includes all possible 3-team parlays on these 3 wagers (A+B+C). If you wager $30 on the By 2’s option, that money will be split evenly among the 2-team parlays ($10 on each of the 3 wagers).

Parlays - these might be the most popular bets out there, especially among novice and amateur bettors, perhaps because of the lure of betting a small amount for a potentially big payoff. But they are fool's gold at best. Parlays involve wagering on two or more games on the same bet following the casino's pre-determined payout scale. Each game on a parlay must win for the bet to be a winner. 

Bets on “Winner of Point”, “Scorer of Goal" and similar offers refer to the participant winning the listed occurrence. For the settlement of these offers, no reference to events happening prior to the listed occurrence will be taken into consideration. Should the listed event not be won within the stipulated time frame, all bets will be declared void, unless otherwise stated.
For example, let’s say that two players are playing a tennis match and one player is +250. You think that this player has a MUCH better chance than that but still is an underdog. Most people would tell you that you are crazy to make a bet on someone that you think is going to lose. The thing is, though, underdogs do win and if you’re getting paid more than you should when they do, you’re going to be profitable. Here’s a simple math breakdown.

"Point Spread" or "Handicap" odds are when it is possible to bet on whether the chosen outcome will be victorious once the listed handicap is added or subtracted to the game to which the bet refers to. In the circumstances where the result after the adjustment of the handicap line is exactly equal to the betting line, then all bets on this offer will be declared void. Example: a bet on -3.0 points will be declared void if the team chosen wins the match by exactly 3 goals difference. Any reference in this section to the term "margin" is intended to be understood as the outcome emerging from the subtraction of the points scored by the 2 opponents.


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.
Sometimes a line will move far enough to create a “middle” opportunity. Say the Texas Longhorns end up facing the Wisconsin Badgers in the first round of March Madness. If you have Texas early as a 5-point favorite, and I move the line to Texas –7 later in the week, then you can also place a bet on Wisconsin +7. If Texas happens to win by six points, both your bets cash in. Texas winning by either five or seven gives you a win and a push. Any other result creates a win and a loss, so you’re only risking the vigorish.
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.

Simply, bigger returns. On a point spread bet you would usually have to spend $105 or $110 to win $100. If you bet on the moneyline you may instead only have to spend $50, or even less, to win $100. You won't win as often, of course, because the underdog not only has to cover the spread, but it actually has to win the game outright. Upsets happen, though, and good handicapping will often isolate situations where the likelihood of an upset exceeds the risk of the bet. This is especially relevant in the NBA because the number of games, and the possibility for even the best teams to have a bad night mean that major upsets are far from rare and can be very profitable.
One of the main reasons that sports bettors like to bet is the action and excitement of winning and losing. Many sports bettors would rather take the risk of winning or losing than having the option of pushing (a tie) on their bets. For this reason, many sportsbooks offer what are called no draw handicap match bets. These are bets on an individual match that are designed so that there is never going to be a tie. In the standard handicap bet examples we used above, you saw that all of the bet options were in whole numbers. This allows for there to be draws.

We went into detail earlier about what causes moneylines to move. The better you can get about predicting when these movements will occur and in what direction, the more profitable you’re going to be as a sports bettor. If you find a bet that you like, but you predict it’s going to move more in your favor, you can intelligently wait to bet and lock up a potentially much more profitable opportunity.
Let's say you decide to bet $100 on Liverpool, and they lose the game by two goals. You would push on the first half of your bet and win the second half of your bet. You would receive your $50 back for the push and $43.48 in profit on your second bet. Basically, the sportsbook would hand you back $143.48 total, which would include $50 for the push, $50 for your original bet, and $43.48 for the push.
If you're seeing 15 or 25 instead of 15/1 or 25/1, you're seeing a decimal form of odds, as opposed to fractional. Multiplying your stake by decimal odds gives your total return, not your profit(which is total return -stake). To get to fractional from decimal, add 1. So 3/1 fractional = 4 decimal (just 4). 4/6 frac = (4/6+1) dec = 10/6 = 5/3, or 1.666, which is rounded to 1.67 by bookies. To go from decimal to fractional, subtract 1(which makes sense from profit = total return - stake) So 15 dec = 14/1 frac. 2.33... dec = 1.33/1, or 133/100.
Single day matchups are wagers on the complete 18-holes for that day. Holes played as part of a completion from the previous day's round, and playoff holes are not included in Single Day matchups. The full 18 holes will be considered in determining the outcome of the bet even if they are played on consecutive days. If both members of the matchup do not complete the full 18 holes, all bets are "No Action". If both players end the 18 holes in a tie, the bet is considered a "No Action" wager.
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.
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.
Let's say you decide to bet $100 on Liverpool, and they lose the game by two goals. You would push on the first half of your bet and win the second half of your bet. You would receive your $50 back for the push and $43.48 in profit on your second bet. Basically, the sportsbook would hand you back $143.48 total, which would include $50 for the push, $50 for your original bet, and $43.48 for the push.
In theory, sportsbooks don't care about the outcome of a game, although for those of you who bet on the Steelers (-5.5) last season versus the Chargers and saw a game winning TD  returned by S Troy Palumalu as the game expired reversed, thus negating a seven point victory and putting the final at 11-10, you might think otherwise, but this is how it's supposed to be.
Anybody who wagers on the 49ers would need them to win by 7 points or more for a winning bet. Those betting on the Rams (+6.5) would need them to lose by 6 points or less (or win) for a winning wager. It's also worth mentioning that a half point is used in many point spreads (such as the -6.5/+6.5) to prevent pushes because no team can score half a point.
This is four different games you can bet on, right? Wrong. These are several different handicap bets that you can make on a single game of soccer. Each of the individual rectangles is the same as the point spread bets we talked about earlier. For example, the first rectangle is betting on Liverpool at -3, getting paid 6 to 1. This means that if you take this bet you need Liverpool to win by four or more goals and you will get paid 6 to 1, or $600 for every $100 you wager.
Handicap league bets are quite similar to the bets we've already talked about except you are now betting on a team's performance across the entire course of the season. Bets are made at the beginning of the season before the first game is played and are not paid out until the last game of the season has been played. Here is a screenshot of some handicap league bets on Premier League soccer.
The last type of handicap bet that we want to talk about is an Asian handicap bet. Don't worry, you don't have to be Asian to place this bet; it's open to everyone. This form of handicap bet is set up through the use of whole, and half number point spreads to ensure that no draws are possible. The difference between Asian handicap bets and no draw handicap bets is that the Asian handicap bets have the possibility of what is called a split handicap outcome. Your bet will have a whole number and a half number line that are treated effectively as two separate bets, but all in the same bet.

Let’s say that the Mavericks and the Magic are playing in an upcoming game, and both teams are equal counterparts. Let’s say that the odds for that game are as follows. You will never see these odds, though, because in this example, the sportsbook is not set to make any money if they achieve their goal of getting money on both sides of the bet. But we need to look at it for you to better understand things.
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.
When betting on the favorite, simply divide the negative moneyline by 100 to get a decimal. If you were planning to bet on the Celtics in the above example, this would give you 2.40 (ignore the negative). Now all you have to do is divide your stake by that number in order to see what your potential payouts would be. Let's say you wanted to stake $650. When you divide that number by 2.40, you'd see that your potential payout is $270.83.

Let’s say the sportsbook has a series of bets that are all +250. You think in reality that the bets should actually be +125 and that the bet is not as big of an underdog as the sportsbook thinks. This means that you think you deserve $125 for every $100 bet that wins but the sportsbook is going to pay $250. Even though you think that the bet is still supposed to lose, you should make this bet.
We already know that the only thing that causes the moneyline to shift are the bets that are coming in. However, we should talk about what factors will cause the betting patterns of the public to change, and in turn, cause the moneylines to move. This will go hand in hand with the following betting strategy section. If you can master predicting when and how lines are going to move, you will crush sports betting and moneyline betting.
As we mentioned, moneyline/win bets take into account who the favorites and who the underdogs are and will pay out winning bets accordingly. Here’s a quick example that will make this clear. Imagine that Mike Tyson (one of the greatest boxers of all time) is going to fight against an 80-year-old man. If the sportsbook let you bet on either side of the fight and paid you the same, would that be fair?
Bets on “Winner of Point”, “Scorer of Goal" and similar offers refer to the participant winning the listed occurrence. For the settlement of these offers, no reference to events happening prior to the listed occurrence will be taken into consideration. Should the listed event not be won within the stipulated time frame, all bets will be declared void, unless otherwise stated.

Almost all point spread wagers are paid out at moneyline odds of -110. This is almost even money minus the percentage that is taken for the sportsbook's cut known as the vig. Sometimes you will see a bit of variation in the payout odds, but for the most part, you should expect to see -110. If you don't see the payout numbers posted but just the point spread, you can most likely assume that you are to interpret that as being paid out at -110. If you're ever curious, though, just ask for clarification or look at your betting slip.
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.
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.
