Because the spread is intended to create an equal number of wagers on either side, the implied probability is 50% for both sides of the wager. To profit, the bookmaker must pay one side (or both sides) less than this notional amount. In practice, spreads may be perceived as slightly favoring one side, and bookmakers often revise their odds to manage their event risk.
So the sportsbooks and bookies created a point spread to make both teams equally attractive in the eyes of bettors. Carolina was installed as a 6-point favorite, which is commonly written as Carolina -6. Denver, the underdog, is commonly written as Denver +6. In other words, Denver would be credited with whatever points they actually scored — plus six. If you bet the favorite, the Panthers would have to win by 7 points or more for you to win your wager. And remember, the Panthers are favored by 6 points, so we have to subtract 6 points from their final score for betting purposes.
What's the difference between an oddsmaker and a bookie? A bookie's job is purely mechanical. He gets the line from Vegas or another source, offers bets at those odds, then collects money from the losers, pays out to the winners and keeps the vig. Oddsmakers don't actually take bets -- they study the games and set the lines. Bookies often adjust the spreads for their games, so they do a little oddsmaking, and oddsmakers work for casinos, which operate sports books that take bets.

The majority of bets on any sport are usually on the final outcome of the particular contest. However, for sports like the NFL and NBA, there are 1st quarter and 1st half lines offered as well. The quarter spread is used to determine who will be the winner at the end of the 1st quarter. The same is true for a 1st half line, only the wager ends when the first two quarters are completed. Generally, the 1st half spread will be close to half of the overall spread on the game.
There might be some movement when injury reports come out, but barring any kind of shocking news development (Tom Brady suspended for the game!), the line likely will not change all that much. The point spread is currently sitting at 2.5 points. I could see sportsbooks dipping into three points to level out the money on each side, but that might not happen until later next week after the teams are wrapping up their practice week. My prediction is the line settles at a field goal heading into kickoff.
*Betting $110 to win $100 obviously is not an even bet. The extra $10 (or 10%) is the sportsbook’s commission, also known as the vigorish or juice. This commission is reduced to 5% with 5Dimes and other reduced juice books, but this commission is found everywhere. You are given this back when you win, but is obviously kept by the house when you lose.
Identify the type of line you are looking at. All online sports books offer you the chance to have your lines in an "American" or "Money line" version. If I were you, I would use this as my standard. An "American" line uses either a + or - before a number to indicate odds. So a -120 and a +120 are two very different odds on a team… I will explain the differences shortly. Two other less common variations exist: decimal odds and fractional odds.

Odds for different outcomes in single bet are presented either in European format (decimal odds), UK format (fractional odds), or American format (moneyline odds). European format (decimal odds) are used in continental Europe, Canada, and Australia. They are the ratio of the full payout to the stake, in a decimal format. Decimal odds of 2.00 are an even bet. UK format (fractional odds) are used by British bookmakers. They are the ratio of the amount won to the stake - the solidus "/" is pronounced "to" for example 7/1 "seven to one". Fractional odds of 1/1 are an even bet. US format odds are the amount won on a 100 stake when positive and the stake needed to win 100 when negative. US odds of 100 are an even bet.
For starters, you will need somewhere to place bets.  If you are in Vegas, great!  You can bet at one of the sportsbooks in their casinos.  As more and more states pass laws to legalize sports betting, you will also be able to place wagers at local casinos in your area.  You could also find a local bookie to bet through, but we recommend betting online.
There’s only one DFS style game in Las Vegas casinos today. US Fantasy Sports can be found in about 14 casinos and it continues to grow. In this type of football betting, you wager on which player will rank 1st, 2nd or 3rd from a pool of players in specific positions. The wagering style is similar to horse racing where you can wager on win, place, and show. You can also make exacta and trifecta wagers. There’s also an option to place a $1 wager and pick winners from all pools to win $1,000,000.
SportsInsights.com’s general betting articles discuss the intricacies of sports betting as it pertains to each major U.S. sport. This article will concentrate on how to bet on the NFL. We will try to utilize that “neck up” part of our bodies to gain an edge on the linesmakers, but first we must know the basics. The NFL is by far the most popular bet of all major American sports, culminating with the most popular game of the year, the Superbowl. This article will shed light on each football wager type including spread, moneyline, totals, parlays/teasers, halftimes, and futures.
The main purpose of placing a wager on a game or event is to win money. That is what drives the industry and it's what has both amateur and pro bettors competing amongst themselves to prove who the best handicapper is. If you ever find yourself placing a bet with the expectation of losing, you are in the wrong business. Whether you can believe it or not, sportsbook place bets from time to time with the expectation losing in order to secure a profit. This term is called the "layoff" Read More >>
In addition to knowing the basics of betting, you should also know at least the basics of football too. It's likely that most people reading this are big sports fans, and fully understand it, but that's not necessarily the case for all our readers. We like to cater for everyone, so we've written the following two articles explaining all about the game at both professional and college level.
For example, the Golden State money line above is listed at -340 odds. Using the same principles we just discussed, $340 needs to be bet in order to win $100. Again, this is just the bet to winnings ratio - $34 will win $10, $17 will win $5, $20 will win $5.88, etc. This may seem unfair at first but it is logical. The Warriors are by far the best team in the league and have a much better chance of winning the game. Therefore, sportsbooks even this out by placing the odds at a high price for bettors to win a little.

These are just a very small selection of some props. Many bookmakers offer dozens of different options, particularly on high profile matches. Props are generally considered a fun type of bet rather than a way to make money, but it is possible to make consistent profits from them. We explain more about props on the following page, where we also offer some strategy advice.


If your sports betting experience consists mostly of office pools during March Madness or a casual wager between you and a friend while you watch the Super Bowl, the transition to serious sports betting means learning how to read betting lines. The biggest difference between making the kind of casual bets mentioned above and placing wagers with online sportsbooks or at brick-and-mortar bookshops is the use of sports betting lines. Casual wagers usually involve each person in the bet picking one team to win, then wagering an equal amount, say $20 or $30. Professional bookmakers, online sports betting exchanges, and sports betting facilities in casinos have a more complex system for offering wagers on sporting events, in part to ensure profit on the part of the book, and in part to present a standardized representation of odds.
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.

The odds given on the spread are usually -110 unless otherwise noted. It is not uncommon to see one side of the spread being -105, with the other side being -115. If you don’t see any odds listed for each side of NFL spreads you are supposed to assume the odds are -110 on each. Not sure how to read NFL betting odds? Check out our Sports Betting Odds guide.
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.
