The simplest way to think about a moneyline is to consider a base bet of $100. A moneyline is a number larger than 100, and it is either positive or negative. A line with a positive number means that the team is the underdog. If the line, for example, was +160 then you would make a profit of $160 if you were to bet $100. Obviously, then, the team is a bigger underdog the bigger the number is - a +260 team is perceived to be less likely to win than a +160 team.
The first number (56.5 in our sample line) is the book’s predicted total score, while the second number (110 in our Giants/Cowboys rivalry game) is how much a punter has to bet in order to win $100. If you were to bet the over-under on this game, you’ll have to decide whether you think the combined score of both teams will be higher or lower than the number put up by the book. Let’s say you bet the over, assuming the game will be a shootout between two talented offenses, you’re hoping that the final score will be anything that totals 57 or more. It could be Dallas 54, New York 3, or any other point combination that adds up to 57 or more and your bet will win. Betting the under means that the two teams cannot score more than 56 points combined, or else you lose your bet.
If you place wagers on US sports, then chances are high that you've heard of point spreads. Here's how they work; if a game has Patriots -9.0 and Vikings +9.0, the Patriots are 9.0 point favorites and the Vikings are 9.0 point underdogs. Unless otherwise stated, no matter which team you bet on, you'll be required to risk $1.10 for each $1.00 you want to win. For Patriots bettors to prevail, they need their team to win by 10 or more points. A 9-point Patriot victory would be a push (a tie). For Vikings bettors to take home the victory, they need to either win the game or lose by less than 9 points.
Generally, the number next to the spread is “-110”. This is what’s known as the juice, vig or odds. The juice is a fraction of the wager taken from the bettor if the bet wins. In this instance, a winning wager of $110 will yield a profit of $100.The example above demonstrates that, although Indianapolis won the contest, Tennessee covered the spread by losing by less than nine points. An important aspect of sports betting is capturing the best line possible. A great way to achieve this is by shopping for the best line.
Money Line: More common in baseball and hockey, pro football moneylines are growing in popularity. There is no spread, so your team just needs to win the game, not win by a certain number of points. The negative value means a favorite (-190) and a positive one indicates an underdog (+170). Picture the number 100 sitting in between these two values. Example: if you want to pick a -190 favorite, you must risk $190 in order to win $100. To back a +170 underdog, you put up $100 and win $170 if the dog wins. In some cases, betting moneylines is actually better value and can provide a bigger profit for less risk.
