One of the biggest factors you will see change the moneyline odds is the news media. The news does a great job of sensationalizing stories as well as reporting changes that may or may not have an effect on an upcoming game. Recreational bettors have a tendency to overreact to news stories, especially ones that pull on the heartstrings. This can create some really awesome betting opportunities for you to jump on. Expert bettors and sportsbook executives always say that if you can be on the opposite side of the general public on a bet, you’re probably in a good spot.


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.
The last format we want to look at is fractional odds. Personally, we aren’t a huge fan of fractional odds because they’re the most challenging to work with. The formula is almost the same as with decimal odds, but it gives your profit instead of total money returned. It also requires you to solve a fraction, which may be a nightmare for a lot of people. Regardless, we are going to walk you through how to do it with the same bet we’ve been working with.

Which brings me to my next point. If you are serious about getting into sports betting, it is vital to have more than one sportsbook to make a wager at. Shopping around for the best lines will help your bankroll and you will be able to turn a bigger profit. If you see a pair of sneakers for $110 at one store, and the exact same pair is $102.99 at another store - which store are you buying them from?
You may often notice that the spread is sometimes set at an even number such as 3, 6 , 10, etc. In this case if the favored team won by the exact amount set for the spread the bet would be pushed, and all bets would be returned. For example, if the Patriots were 3 point favorites and they won by a FG (3 points) than this would results in a push, meaning no matter which side you bet on you would get your money returned to you.
When betting on American sports such as NBA or NFL, there are usually two main categories that appeal to punters. These are the point-spread or the moneyline. With spread betting there is a 50% chance to win on either side since the spread is actually a handicap that is given to the underdog to even out the chances for both teams on a game or a match. The majority of the time, punters will win just about the amount they bet on a point spread. Moneyline bets can be a bit more complicated and there is no point spread involved. In fact, it is a simple bet to place as one will simply be choosing who will win the game.
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.
You can never rule out the weather in sports. If there is a team or contestant who does better in certain conditions but worse in others, you’re going to see a line movement if the conditions change. For example, a football team that has a strong passing attack might become less of a favorite if rain pops up in the forecast. Often, the line does not shift as quickly as it should in response to changing weather conditions, which can create some good opportunities to find value.
In North American sports betting many of these wagers would be classified as over-under (or, more commonly today, total) bets rather than spread bets. However, these are for one side or another of a total only, and do not increase the amount won or lost as the actual moves away from the bookmaker's prediction. Instead, over-under or total bets are handled much like point-spread bets on a team, with the usual 10/11 (4.55%) commission applied. Many Nevada sports books allow these bets in parlays, just like team point spread bets. This makes it possible to bet, for instance, team A and the over, and be paid if both team A "covers" the point spread and the total score is higher than the book's prediction. (Such parlays usually pay off at odds of 13:5 with no commission charge, just as a standard two-team parlay would.)
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.
The first number in the listing pertains to the order this game appears on a sportsbook’s board. The next NFL game would be listed as #103 for the road team and #104 for the home team. You can think of these numbers in the same way that each horse in a race has its own betting number. The next big takeaway from this listing is that the top team is always the road team (thus the odd number) and the bottom team is playing at home.
Notice that point spreads adjust the score for the favorite team. This is easiest to see with an example: If the New York Knicks are playing the Boston Celtics, and Boston is favored to win by a 4-point spread, then a bet on Boston only pays out if Boston wins by more than 4 points. A bet on New York pays out if New York wins or if they lose by less than 4 points.
When wagering against the spread, you bet on the team that will cover the betting line, and not necessarily win the game. Obviously by taking the favorite, a bettor believes that team will not only win the game, but also win the game by a certain number of points to cover the betting line. But when wagering on the underdog, that team does not necessarily have to win the game to cover the line. For examples of point spreads and how those bets are won, please keep reading below where we explain betting odds for the spread in detail.
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:
Without losing you with the math, the implied probability (or how often you should win) of a +250 bet is 28.6%. This means that you should win this bet 28.6 out of 100 times. This is what the sportsbook thinks will happen. You, however, think it should be +125. The implied probability of that is 44.4% meaning that you think you should win the bet about 44.4 out of 100 times.
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.
This is a very common occurrence throughout the sports betting industry. Sportsbooks have the right to shift the spread or odds for any given match prior to it starting. Many factors play a huge role in this decision, and they include injuries, weather, the volume of bets on one side, and anything in between. Depending on the time you place your wager, the bettor may also have an advantage or disadvantage based on which way the spread has shifted.

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.
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.
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.
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.
