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]
Oftentimes you’ll see a point spread that has a half-point added to the number. Of course, there’s no such thing as half a point in a football game, so why do we so often see point spreads with a (.5) attached to the score? Sportsbooks do this to make sure there isn’t a chance of a push.  Let’s take another look at our game from above with the half point added.

For example, let’s say that two players are playing a tennis match and one player is +250. You think that this player has a MUCH better chance than that but still is an underdog. Most people would tell you that you are crazy to make a bet on someone that you think is going to lose. The thing is, though, underdogs do win and if you’re getting paid more than you should when they do, you’re going to be profitable. Here’s a simple math breakdown.

While we're going to cover this extensively in the moneyline section of the Basketball Betting Guide, we'll touch briefly on what the -110 means here. -110 refers to the moneyline payout for a particular bet. If you were to bet $100 on a basketball point spread paying -110 and win, you would be paid out a profit of $90.90. The easy way to figure out the amount you will get paid with minus moneyline odds is to divide your bet size by the absolute value of the betting odds and multiply that number by 100.


Betting on the point spread is completely different from betting on teams to win a game outright. Known as "betting on the moneyline", instead of using points to handicap each side of the wager, the sportsbook will use greater payouts versus the amount risked to reflect their relative perceptions; teams not expected to win (underdogs) pay more, sometimes exponentially, than when betting on the favorite to win when wagering on moneylines.

In general, the betting public tends to gravitate towards favorites when betting the games regardless of the actual pointspread. This is especially true with high-profile teams such as Dallas and Green Bay in the NFL and Golden State and Cleveland in the NBA. The sportsbooks are well aware of this phenomenon and often times they will adjust the betting spreads accordingly. This, in turn, actually adds some value to the underdog when you consider that a pointspread is nothing more than a handicapping tool that is designed to even out the match.
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.
It is a very good idea to shop around to find the best line when you are betting on sports. Books may offer slightly different lines, and you might be able to gain a point or half a point in your favor on certain markets. Consider an NBA game between the Heat and the Lakers – one firm has the Heat 9.5 point favorites and another have the Heat as 8.5 point favorites. You back the Heat with the second firm and they win by exactly nine points. Here you’ve gone from a loss to a win simply by shopping around, and in the long run this will make a big difference to your bottom line.

Especially in major tournaments, some sports books offer odds on unusual golf propositions, such as the over/under on the winning score, the over/under on the lowest round by any golfer or the over/under on the finishing position by a particular golfer. For example, the over/under on Woods' finishing position may be 3 1/2. If he finishes first, second or third in the tournament, the "under" wins; if he finishes fourth or worse, the "over" tickets cash.
If you want to bet on football, then you have plenty of options. There are not only lots of games you can bet on, there are also lots of different types of wagers you can place. Point spreads and totals are the most popular types, by quite a distance, and many football bettors stick solely to those. This isn't really the ideal approach, as some of the other wagers can be very useful in the right circumstances.

Sportsbooks will use a variety of methods to set their line on a game. Some firms will use computer simulations, some will use a form of power ratings, some will use an experienced team to set the line – some may even use a combination of all three. Other books may even wait to see where their rivals set their lines before dipping their toe in the water themselves.
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.
In the UK and some other European countries the profit from spread betting is free from tax. The UK and some other European countries tax authorities designate financial spread betting as gambling and not investing, meaning it is free from capital gains tax and stamp tax, despite the fact that its regulated as a financial product by the Financial Conduct Authority in the UK. Most traders are also not liable for income tax unless they rely solely on their profits from financial spread betting to support themselves. The popularity of financial spread betting in the UK and some other European countries, compared to trading other speculative financial instruments such as CFDs and futures is partly due to this tax advantage. However, this also means any losses cannot be offset against future earnings for tax calculations.
Apply the money line. It's easiest to think of money lines in relation to $100. A minus sign means you have to bet that much money in order to win $100; a plus sign means that a $100 bet will return that much money. If you bet on Chicago at -110, you'll have to wager $110 in order to get back $100 (plus your original $110). If you bet on Detroit at +145, then a $100 bet will give you $145 (plus your original $100).
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. 

As you can see, each team is listed, followed by the adjustment or line change for each team, and then the odds that you would be paid out. If you notice, Chelsea has the word scratch next to their name. This is because they are the league favorite to win and all other adjustments are made about them. If your team is in first place at the end of the regular season after the adjustments are made, you will win your bet and be paid the posted odds. As you can see, the odds pay out fairly well on these bets as they are season long and are more difficult to win.
The most important thing you can teach yourself early on is: "Just because the books assign one side to be the favorite (even large, -200 or -300, favorites), does not mean that they will win." We have all seen favorites get upset, and it is important to avoid the temptation of finding comfort in the fact that the lines makers put one team as a favorite.
When unforeseen events occur such as weather, power outages, or any other unanticipated event once the game has started, many people wonder how that will affect the wager. If an event has not started, all wagers should have no action and be refunded. But if the event has started and is interrupted and not completed it gets a little more complicated. The following will examine the special rules for each sport and give you a better idea of what to expect should the event not be completed on the same night. Always check with your book to know any special rules that may apply but according to the letter of the law: the following is how each event should be interpreted.
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
Something that all of our pro bettors on staff preach is that there is no reason to make anything more complicated than it needs to be. Specifically, they are referring to the awful trend of aspiring sports bettors thinking that you must make more complex bets in order to make a living betting sports. The reason we say it’s an awful trend is because this couldn’t be further from the truth.

This is a huge difference. The potential profit on the moneyline wager ($143) is over 40% greater than that of the point spread wager ($100). You're a little less likely to win, as there is a chance that Seattle would lose by one or two points, but there's a more than fair chance that if they did cover they would actually win the match. And, of course, if they lost by three or more then you'd have lost either way.

Moneylines have a tendency to move quite a bit in both directions leading up to a game, match, or fight. It’s a delicate dance that you’re going to have to master if you want to find value and push your edges to the max. Sports betting is a profit source that is all about small edges. Finding and being able to capitalize on these small edges is the key to being profitable long-term.
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.
It's inevitable in sports and basketball that in each game one team is going to be better than the other. Betting would be a little pointless if you were able to make the exact same wager on each team. Everyone would just always bet the better team, and the sportsbook would quickly be out of money and have to close up shop. What point spread bets attempt to do is even the playing field and offer bets with the same risk level on both sides of the coin. They effectively aim to create a 50/50 even playing field.
Score three is usually the one that confuses people. Remember, when betting on point spreads, the favorite has to win by more than the number of points they are projected to win by. The underdog can lose the game, and you can still win your bet as long as they don't lose by more points than they are spotted. In the above example, if you were to bet on the Chargers at +3, you can imagine that like you have three bonus points to play with. You can lose by one point or by two points and still win the bet. If you bet the Chargers at +3 and lose by three points, it is a tie.
The number that follows the plus or minus sign will indicate how big of a favorite or an underdog the team is. The larger the number is, the bigger the favorite or the underdog the team is. For example, a team that is -300 is a bigger favorite than a team that is -150. A team that is +240 is a bigger underdog than a team that is +130. Remember, this is not the sportsbook’s actual prediction on who they think will win; it’s in relation to the money that has been bet on the game. It is more depictive of who the betting public thinks is going to win the game.
A good rule of thumb with sports betting is that the sportsbook is going to put more time, effort, and resources into setting their lines on the sports and leagues that have the most action. This is a completely smart move on their part as it's where they stand to lose the most money if they make a mistake. What this means is that the smaller sports and leagues are much more likely to have bad lines or lines that don't respond as quickly to trends as they should. Regarding basketball, this means you may have more luck looking into college basketball or even the smaller European leagues. If you do choose to go this route, make sure that you do all of your homework and are not just jumping into a new league blind. College basketball and Euro league betting are NOT the same as NBA betting even though they are the same sport. This does not mean you can't bet the NBA and that you won't find great lines; it just means that the bad lines are more likely to be corrected quicker as the sharp bettors will jump all over them, and the sportsbook will adjust.
If the public comes out and bets really hard on one side, the line is going to move a lot making the odds worse on that side and a lot better on the other side. If you’re planning to bet against the public, you should wait to bet until the line moves as far as you think it is going to. Be careful, though, if you wait too long and some big money bettors bet, they can move the line back.
If you are able to interpret NFL odds and know what the various terms mean, such as the rotation number, point spread, moneyline and over/under, you’ll have a basic understanding on what you are betting. Prior to wagering make sure you see our NFL odds page, which carries all the latest odds from the top online sportsbooks. Remember that the odds makers are attempting to even the out the bets on each game. The sports bettor has to analyze each game and the odds and make their bets accordingly in order to win cash.
This should hopefully make perfect sense to you. Successful betting, on any sport, is all about finding value, so you should always look to get the best value that you can. If a moneyline wager offers the best value on a football game, then that's the wager you should be placing. If a point spread seems the best option, then go down that route. There may even be occasions where it's viable to place both wagers on the same game.

This is because different bookmakers and betting sites price up games differently. So the odds they offer are not always the same. Remember the Packers versus Cardinals game we showed earlier as an example? We used the actual odds from a real betting site for that example. The following odds were also available for the same game, from various other sites.
All of this is exactly the same for betting on Southhampton except you use the spreads and odds payouts that are underneath their team. You can also bet on the tie in a lot of sports, especially soccer. In the above example, the spread points would be added to Southhampton for calculations. This means that if you bet +3, you would need Southhampton to lose by exactly three goals.
On the other hand, underdog moneylines can be lucrative wagering opportunities. Upsets happen more often than some of us think and moneyline betting is a great way to take advantage. For example, for a moneyline wager of +250, a bettor will only need to win about 28% of the time to break even and for a +300 wager the bettor would only need to win 25% of the time to break even. If you can spot upsets even decently well, moneyline wagers on underdogs can be profitable bets.

Let’s say the sportsbook has a series of bets that are all +250. You think in reality that the bets should actually be +125 and that the bet is not as big of an underdog as the sportsbook thinks. This means that you think you deserve $125 for every $100 bet that wins but the sportsbook is going to pay $250. Even though you think that the bet is still supposed to lose, you should make this bet.
There's another reason to bet the underdogs on the moneyline as well. If your handicapping has made you feel very strongly that a poor team is due for a big win then the moneyline allows you to profit much more handsomely from your conclusion than a point spread bet does. The moneyline, then, is a powerful situational tool for people who closely follow the NBA.
82 games per year means a lot of opportunities to wager on your favorite teams and Sportsbetting.ag sees that opportunity and gives you what you want to bet on. Sometimes this means having spreads for big games a day or two in advance, especially if both teams are off the day before the big matchup. They take care of their NBA bettors... give them a shot.

Below we have also put together an infographic explaining all of the information on this page.

But what if the basement-dweller team was spotted 24 points? That's the concept behind the point spread. When two teams meet on the football field or a basketball court, one team is typically better than the other. If all bettors had to do was to pick the winning team, everybody would simply wager on the best team and collect their money. Gambling institutions, sportsbooks, and bookies would soon go broke. 
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value.  The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
