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.
Pools, cards, and parlays - A parlay is just a combination bet. Instead of making five separate bets on five different games, the bettor places a single parlay bet, hoping he or she can predict the outcome of all five games. If any one of the games is a loser, the entire parlay is a loser. The payout is better for parlays, because the odds of successfully picking multiple winners are much tougher to beat [ref]. Most people are familiar with parlays through office betting pools or football cards. If you've ever paid $5 to select your winners from a list of that week's football games (sometimes using the spread, sometimes using the straight scores) in hopes of winning the weekly prize, then you have made an informal parlay bet. Office pools don't usually involve actual bookies beyond the person who organizes the pool, and no one takes juice from the pool. All the money is distributed to the winner or winners.

In this example the Jets are listed as four-point favorites (-4) over the Bills and the 49ers are three-point underdogs (+3) against the Seahawks. So, if you bet $110 on the favored Jets, they must defeat the Bills by more than four points in order to win $100. If you bet $110 on the underdog 49ers you will win $100 if they win outright or lose by less than the three-point spread. If the final score happens to end up exactly on the number it's a tie, or 'push,' and you get your money back.
By far the largest part of the official market in the UK concerns financial instruments; the leading spread-betting companies make most of their revenues from financial markets, their sports operations being much less significant. Financial spread betting in the United Kingdom closely resembles the futures and options markets, the major differences being

I’ve titled this Sports Betting For Dummies. It’s a tutorial for those who want to start betting on sports or those who want to gain a better understanding of some of the terminology and theory behind it. We’ve all been in the position of learning something new, so please don’t be embarrassed if you don’t grasp these concepts. Instead, contact me via the form at the bottom of this page, and I’ll help you in any way I can.


Many reasons contribute to why point spread betting is one of the most favored by NFL players, certainly one reason it is so attractive to the recreational player is that essentially you have a 50-50 proposition on every team no matter who they are playing meaning you have the opportunity to bet your favorite team no matter who their opponents and in theory have a 50% chance of winning your bet at reasonable odds. Take the 2008 Detroit Lions who went through the regular season without winning a game, now betting them on the NFL money line odds would have been a disaster whereas their point spread record for that season was 7 wins and 9 losses. Similarly the 2007 Dolphins went through the NFL regular season with only one win however their point spread record stood at 5 wins, 7 losses and 4 pushes against the closing line.
Major League Soccer (MLS) the top soccer league in the United States and Canada has expressed sports betting as a possible way to gain popularity. Commissioner Don Garber has stated about sports gambling, " We have a project going on now to really dig in deeply and understand it. I’ll join the chorus of saying it’s time to bring it out of the dark ages. We’re doing what we can to figure out how to manage that effectively."[49]
Many casinos around the world contain a sportsbook. They usually feature several big screen TVs showing any live sports action currently taking place, and computerized odds boards displaying all the latest odds. There are typically cashier windows where you can place your wagers with a real person, but some books have interactive machines instead. Either way, these are great places to place some bets and watch the games at the same time. The problem for Americans, though, is that they are only legal in Nevada. There are plenty of sportsbooks in Las Vegas casinos, but not in other parts of the country.
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.

Wagering on the NFL revolves around the point spread in which one team is designated the favorite and the other team is called the underdog. The NFL point spread sets a specific number of points that the favorite must win by in order for a person betting that particular team to win their wager. Lets use an example from last week's NFL slate to demonstrate the art of NFL point spreads. This past weekend the New England Patriots played the Seattle Seahawks. The Patriots were four point favorites in that game. So in your local newspaper, you might have seen something similar to this illustration.
Say the Bears are a six-point favorite over the Lions and the total is 42. To bet the Bears, you must "lay the points," meaning they must win by seven or more to cover and give you the win. Betting the underdog Lions, you are "taking" six points, and they can lose by five or fewer, or win the game outright, and you have a winning bet. If the Bears win by exactly six, both sides "push" and all bets are returned. It's also a push if the final score equals 42, otherwise the over or under will win.
Above, you can see several numbers to the right of both teams. These all represent the different lines that are available on the San Francisco vs. Los Angeles game. The first set of numbers for both teams is the point spread, the second set is the moneyline, and the third set is the over/under (a.k.a. totals). We'll explain each of these lines more in-depth below.

If you've never set foot in an actual sportsbook before or logged into an online sportsbook, the chances of you getting overwhelmed when you actually do is very high. In an actual Las Vegas sportsbook, there is typically a lot of commotion and the odds and lines are displayed on a massive digital board for everyone to see. When a novice sports bettor looks at the massive digital signage, they will see a bunch of numbers, both positive and negative, some two digits, some three digits. They also won't have a clue what any of it means. The same can be said for the online sportsbooks. It looks like a massive spreadsheet with negative and positive numbers beside each teams' name.

In addition to the spread bet, a very common "side bet" on an event is the total (commonly called the over/under or O/U) bet. This is a bet on the total number of points scored by both teams. Suppose team A is playing team B and the total is set at 44.5 points. If the final score is team A 24, team B 17, the total is 41 and bettors who took the under will win. If the final score is team A 30, team B 31, the total is 61 and bettors who took the over will win. The total is popular because it allows gamblers to bet on their overall perception of the game (e.g., a high-scoring offensive show or a defensive battle) without needing to pick the actual winner.

Spread betting has moved outside the ambit of sport and financial markets (that is, those dealing solely with share, bonds and derivatives), to cover a wide range of markets, such as house prices.[5] By paying attention to the external factors, such as weather and time of day, those who are betting using a point spread can be better prepared when it comes to obtaining a favorable outcome. Additionally, by avoiding the favourite-longshot bias, where the expected returns on bets placed at shorter odds exceed that of bets placed at the longer odds, and not betting with one’s favorite team, but rather with the team that has been shown to be better when playing in a specific weather condition and time of day, the possibility of arriving at a positive outcome is increased.
The concept of betting on totals, or Over/Under (O/U), is quite simplistic. The bettor wagers on whether the TOTAL points scored in a game will fall over or under a pre-determined number set by the sportsbook. Much like the point spread, game totals can be swayed by public opinion. The example below, from the SI Archive, shows the opening totals line for Superbowl XLV:
Financial spread betting is a way to speculate on financial markets in the same way as trading a number of derivatives. In particular, the financial derivative Contract for difference (CFD) mirrors the spread bet in many ways. In fact, a number of financial derivative trading companies offer both financial spread bets and CFDs in parallel using the same trading platform.
In 1919, the Chicago White Sox faced the Cincinnati Reds in the World Series. This series would go down as one of the biggest sports scandals of all time. As the story goes, professional gambler Joseph Sullivan paid eight members of the White Sox (Oscar Felsch, Arnold Gandil, Shoeless Joe Jackson, Fred McMullin, Charles Risberg, George Weaver, and Claude Williams) around 10,000 dollars each to fix the World Series. All eight players were banned from playing professional baseball for the rest of their lives.[56] Pete Rose, the all-time MLB leader in hits, was similarly banned from baseball in 1989 for betting on games while he was an MLB manager.
The general purpose of spread betting is to create an active market for both sides of a binary wager, even if the outcome of an event may appear prima facie to be biased towards one side or the other. In a sporting event a strong team may be matched up against a historically weaker team; almost every game has a favorite and an underdog. If the wager is simply "Will the favorite win?", more bets are likely to be made for the favorite, possibly to such an extent that there would be very few betters willing to take the underdog.
Spread betting are wagers that are made against the spread. The spread, or line, is a number assigned by the bookmakers which handicaps one team and favors another when two teams play each other and one is perceived as being more likely to win. The favorite "takes" points from the final score and the underdog "gives" points. This number can also be in increments of half-a-point (.5) even though very few sports have .5 point scoring (i.e., The Ryder Cup)
One of the single most important pieces of advice for any form of gambling is to set aside a sum of money that is exclusively for the relevant activity. It should be money that is not needed for anything else, that you can afford to lose, and that you are comfortable putting at risk. This money will be known as your bankroll, and it's effectively the most important tool a bettor has at his disposal.
In today's world, online shopping is all the rave. Sites like eBay and Amazon have taken the world by storm and people do whatever they can to avoid setting foot in a retail store. Unfortunately, there will be times where you receive your order and it's completely wrong or it looks nothing like you saw in the picture. Thankfully, you have the ability to get your money back and try again. To put that situation into sports betting context, let's talk about baseball. Baseball offers a unique bet called "listed pitchers" where your bet only goes live if the listed pitchers start the game. If not, just like Amazon, you will get a refund. Read More >>
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.
As the numbers grow larger each way – the small numbers get smaller or the positive numbers get larger – that indicates that those options are bigger and bigger favorites, or bigger underdogs. That’s particularly relevant when you’re looking at something like the odds to win the Super Bowl. The teams with smaller numbers are deemed as having a better chance of winning and then as the numbers grow larger, those teams are deemed bigger and bigger longshots.

In a national poll released in December 2011, Fairleigh Dickinson University's PublicMind asked voters whether they “support or oppose changing the federal law to allow sports betting” in their respective states. Just as many voters approved (42%) as opposed (42%) allowing sports betting. However, voters who already live in households where family members (including themselves) engage in sports betting had a strongly favored legalization of sports betting (71%-23%), while voters in households where sports betting is not an activity, opposed legalization (46%-36%). Peter J. Woolley, professor of political science and director of the poll commented on the findings, “Gambling has become, for good or ill, a national industry, and you can bet that politicians and casinos all over the country are closely following New Jersey’s plans.”[8]

The odds listed are a primary way of gauging the play in the game. There are hundreds of mismatches every single year and the leveling of the playing field has been very helpful in resolving that particular problem. With the use of odds, bookies are able to acquire an equal number of wagers on each team, which assures them that they get money regardless of who wins.


For UK spread betting firms, any final outcome that finishes in the middle of the spread will result in profits from both sides of the book as both buyers and sellers will have ended up making unit point losses. So in the example above, if the cricket team ended up scoring 345 runs both buyers at 350 and sellers at 340 would have ended up with losses of five unit points multiplied by their stake.
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. 

In June 2017, the Supreme Court of the United States announced that it would hear New Jersey's case, Murphy v. National Collegiate Athletic Association, in the fall of 2017, contradicting the position of the US Acting Solicitor General, Jeffrey Wall, who asked that the case not be heard in May 2017.[18] In September 2017, a poll conducted by the Washington Post and the University of Massachusetts Lowell shows 55% majority of adults in the U.S. approve of legalizing betting on pro sporting events.[19]
As you can see, there’s another number in our example above. The –110 in parentheses refers to the juice; this figure is expressed in the same fashion as moneyline odds, with either a negative or positive sign in front of the number. In this case, in order to place a wager on either side, you would have bet $110 to win $100. If the juice on Kansas City had been +110, you would have bet $100 to win $110. Most NFL game lines ask you to pay the standard –110 vigorish. If you don’t see any particular figure attached to the spread, the usual –110 vig applies.
Each week we see the volatility in the pro football point spread market with opening spreads often but not always moving and closing at a different number. In general the movements are caused by the weight of money on one side or the other however injury rumors or confirmation of an injury to a key player, unrest in a particular NFL team's management or any number of other reasons can contribute to a point spread line being reassessed and changed by the sportsbooks. The question is often asked then, is it better to place your NFL point spread wager early on the opening lines or wait until the hour or two before kick off? There are certainly pros and cons for both which are discussed further in The Football Lines .com's When to Place Your NFL Bet article however ultimately there isn't a definitive right or wrong answer as varying NFL betting situations can require a different and flexible approach.
The Jets are favored by 7 points. When you wager on the Jets -7 points, they have to win by 8 or more for you to get paid. A win by exactly 7 points would be a push and you get your money back. If you wager on the Giants +7 points, you’ll need them to win or lose by 6 points or less to win your bet. The Giants can win the game and you’ll win the wager because they didn’t lose by 7 or more. A loss by exactly 7 points would be a push and you get your money back.
If you're an amateur bettor that's just starting out and are in desperate need of a quick betting terminology lesson, you've come to the right place. For starters, I would like to believe that you are starting out by picking teams that you believe will win the game outright. That would be known as a money line bet. If you are a bit more advanced then that, you would probably be looking at betting the "line" on a particular event. To some, this is known as the spread and that's completely fine, but if you ever come across a conversation involving the "line" this article will prepare you for what it actually means. Read More >>
Baseball. It's America's pastime. A game that prides itself on being perfect in every way imagina-ble. It's almost as much an individual sport as it is a team sport when you consider that in every game and in every inning, a pitcher faces one batter at a time, and whichever player wins that battle brings their team one step closer to victory.
