Money line bets are particularly attractive to square bettors when they are looking at underdogs. They see a nice high positive number and think that the payoff is significant enough to be worth the risk. Unfortunately, underdogs are underdogs for a reason, and it’s usually because they aren’t very good. However, when the right opportunity presents itself, a money line bet on an underdog can grow your bankroll quicker than betting favorites would.

Of course, it wouldn’t be. Everyone would bet on Mike Tyson, and the sportsbook would lose all of their money and close the next day. So what the sportsbooks do is they assess who is the favorite and who is the underdog and assign a value to how much in each direction they think they are. Let’s look at what the odds might look like for our fictitious fight and break down what everything means.

Linemakers who work for the sportsbooks must put out lines that will entice the "favorite" bettors to lay the points and take the favorite or entice the underdog bettors to take the points with the underdog. Because each sportsbook is operated under their own rules, guidelines and stipulations, they are free to put out whatever line they feel is competitive and charge whatever vig they want to based on how much action that specific line is taking.

^{Why is this important? If you’re only looking for a fun sweat, it does not matter at all. But, if you’re looking to be a winner and making money long-term is important, then this becomes critical. For those of you profit-minded bettors, make sure that you are only betting on the prop bets that require quite a bit of skill. These bets will be the ones that your knowledge, research, and expertise will help you win over the long run. }

_{You've probably noticed by now that in the first game there are no odds posted in parenthesis to the right of each team. This means that the sportsbook is paying out both bets at the standard odds for a point spread bet of -110. Some sportsbooks will write the -110 in, and some will just leave it blank assuming that you know they will be paying out at the standard odds rate. }

**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.**

*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.*

**The 2-way moneyline is what most North American bettors would simply refer to as “the moneyline”. This is one of the most common wagering options where the user bets which side will win the game straight up. (A draw or tie results in a push with the 2-way moneyline.) The term is sometimes highlighted during soccer betting to differentiate from the 3-way moneyline - a more popular option with the draw added as a wagering option.**

**One way to make money from sports betting is to open an account at an online betting site and take advantage of their sign up bonus. This gives you extra money to wager with, and since point spreads are so straightforward, it can be relatively easy to meet the associated wagering requirements and still come out ahead. Repeating this process at multiple betting sites will maximize your potential returns! We just ask that you please stick with reputable sites, like any of the ones that we recommend.**

##### 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:

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.

#### 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.

For those of you that are smart, you know that this is probably the most valuable section of this entire guide. We’ve decided to give you free access to our expert team of NBA bettors and all of their game picks. You’ll get to see exactly who they’re betting on, what odds they’re taking the bets at, and any other information they deem pertinent. Not only that, but these picks will be written in a blog-style format which means you’ll get a full breakdown of why they are choosing the teams and bets they are. This will allow you to get inside the minds of the experts and start to learn and be able to mimic their winning habits.

_{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. }

Moneyline bets can be presented in three different formats including moneyline, decimal, and fractional. While these will look very different, they will tell you the exact same information about the bet including who you are betting on, who the favorite or underdog is, and what the potential payout you would receive from a correct pick. We will cover all of this in the next few sections.

`When the point spread was invented in Chicago by Charles McNeil the money line took a backseat. When two unevenly matched teams played, the playing field was leveled by having the favorite give points (for example Chicago Bears –7) while the underdog got points (Minnesota Vikings +7). No matter which team the bettor took the bettor would always risk $110 to win $100. The extra $10 needed to win $100 is called the juice or the vig, it is basically the house’s or the bookie’s take. It’s 10-percent of the bet so it would take $33 to return $30 and $440 to return $400 etc. (winning bettors get the vig back).`

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.

*In most football games there is a favorite and an underdog. Very occasionally there are games where the two team are completely evenly matched, but for the most part one team is favored over the other to win. With point spreads, the idea is to create an even money proposition when betting on the game. So the favorite has to win by at least a certain number of points for a wager on them to be successful, and the underdog has to lose by no more than a certain number of points for a wager on them to be successful. The bigger the gap in quality between the two teams, the bigger the point spread.*

_{Oddsmakers want you to gamble on underdogs as well as favorites. They set points spreads that encourage balanced betting. They analyze the strengths and weaknesses of each team, factoring in won-loss record, strength of schedule, results against common foes, key injuries, recent performance and previous games between the teams. They also rate the value of home field advantage and consider the game day weather forecast where relevant. If they see heavy wagering on the favorite, they will increase the point spread during the week to spur more betting on the underdog. If more money is going on the underdog, the spread will decrease as game time nears. }

###### 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.

# 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.

__You can bet the money line option in every single sport that is offered up. It is the simplest form of betting and it is also the primary way to bet sports in which a point spread isn’t available (think hockey or baseball). Money line wagers are also available in football and basketball, but the point spread wager is much more popular. It is also used in tennis, golf, boxing, MMA, cricket, table tennis, and any other sport you can think of that has a winner at the end of the game.__

**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.**

`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.`

^{The first thing you’ll notice with moneyline odds is that there is either a positive or negative sign in front of the number. What that sign denotes is how much you’ll win betting on each side. If there’s a positive sign next to the odds, that indicates the amount of money you would win if you bet $100. If the odds on a tennis player said +150, that means that for a $100 bet, you would win $150. Now if there is a minus sign in front of the odds, that is the number that you would have to bet in order to win $100. For example, if a football team was -250, that means you’d have to bet $250 to win $100. }

_{A spread is a range of outcomes and the bet is whether the outcome will be above or below the spread. Spread betting has been a major growth market in the UK in recent years, with the number of gamblers heading towards one million.[1] Financial spread betting (see below) can carry a high level of risk if there is no "stop".[2] In the UK, spread betting is regulated by the Financial Conduct Authority rather than the Gambling Commission.[3] }
