The National Basketball Association (NBA) has always been a staple of the sports betting community. As a part of one of the big four sports, bettors have been working to develop systems to best the basketball betting industry for decades. Some have succeeded and enjoyed the spoils, while some have fallen. Our guess is that most of those who have fallen did so due to a lack of effort, a lack of information, or just no knack for the sport.
If a team favored by six points wins by exactly six points, the outcome is considered a "push" and the bettors get their money back, minus the bookmaker's commission. To reduce the number of pushes, oddsmakers often set spreads with half-points. So if the Cowboys are 3 1/2- or 3.5-point favorites over the Giants, they must prevail by four or more points to pay winning bets.

So to solve the first fraction for the Heat, we do 13 divided by 20 and get 0.65. Let’s look at our calculations for the $10 bet and the $250 bet. If we bet $10, we multiply our solved fraction of 0.65 by $10 and get $6.50. This is our correct profit! If we bet $250, we multiply our solved fraction of 0.65 by $250 and get $162.50. This is out correct profit!


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.
If the Cowboys are 6-point favorites, their odds are -6. If the Giants are 6-point underdogs, their odds are +6. From the oddsmakers' perspective, the Giants are starting the game with a 6-0 lead, while from the Dallas side, the Cowboys are starting with a 0-6 deficit. If you bet on the Cowboys and they win 34-30, they failed to cover the spread by two points. If you bet on the Giants, they beat the spread by two points.
Is that each game will have a favorite and an underdog. Even in contests where it’s a toss-up, the sportsbook will select someone as the favorite and the underdog for betting purposes. Depending on how big of a favorite or underdog the team or player is, the payout will be adjusted. The bigger the favorite, the smaller the payout. The bigger the underdog, the larger the payout.
When betting on the favorite, simply divide the negative moneyline by 100 to get a decimal. If you were planning to bet on the Celtics in the above example, this would give you 2.40 (ignore the negative). Now all you have to do is divide your stake by that number in order to see what your potential payouts would be. Let's say you wanted to stake $650. When you divide that number by 2.40, you'd see that your potential payout is $270.83.

With NFL odds the over/under can vary but usually it’s somewhere between 35 and 47 points. Let’s say in the Colts and Bengals game that the total is posted at 37.5. If Indy scores 27 and Cincy gets 13 points, the total would be at 40 and the over would win. But if the Colts rack up 35, and they shut out the Bengals, the total of 35 would be under.
You can never rule out the weather in sports. If there is a team or contestant who does better in certain conditions but worse in others, you’re going to see a line movement if the conditions change. For example, a football team that has a strong passing attack might become less of a favorite if rain pops up in the forecast. Often, the line does not shift as quickly as it should in response to changing weather conditions, which can create some good opportunities to find value.
Settlement of bets which make reference to terms such as "decisive goal" will be settled based on the scorer of the goal that at the end of the match/tie,) proves to be the one that has produced an unassailable lead, following which any further goals would prove to be irrelevant towards the final outcome. For a bet to be settled as "YES", the listed player's team must be declared the winner of that particular match or progressing to the next round or winning the competition. Goals scored in Regular Time and Extra Time count but Penalty Shoot outs do not.

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]
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
In North American sports betting many of these wagers would be classified as over-under (or, more commonly today, total) bets rather than spread bets. However, these are for one side or another of a total only, and do not increase the amount won or lost as the actual moves away from the bookmaker's prediction. Instead, over-under or total bets are handled much like point-spread bets on a team, with the usual 10/11 (4.55%) commission applied. Many Nevada sports books allow these bets in parlays, just like team point spread bets. This makes it possible to bet, for instance, team A and the over, and be paid if both team A "covers" the point spread and the total score is higher than the book's prediction. (Such parlays usually pay off at odds of 13:5 with no commission charge, just as a standard two-team parlay would.)
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.
A quick word on that annoying half point in the point spread – most lines you’ll come across will use half points, but it’s not standard practice across the board. When you see a line with a full number instead of a number with a half point, your wager could end up as a push. In our example, if the line were 7 instead of 7.5 and the final difference in points was exactly 7, your wager is returned to you, and neither you nor the book makes money.
How the point spread works - When two teams meet on the playing field or on the basketball court, one team is typically better than the other or in a more favorable position because of factors like playing at home. If all you had to do were pick the winning team in a game, everybody would simply wager on the best team or the home team in a even matchup and bypass all the lines and collect their winnings at a high rate.
For those who are just starting to place sports wagers online, moneylines can be a bit confusing and overwhelming. They differ from point spreads, which are more concerned with the winner and by how much they win. With moneylines, the winning bet will be based on who wins and that is it. These types of bets are usually placed when betting on low-scoring games such as hockey or baseball, but they can also be an option with boxing and some mixed martial arts. The key to understanding moneyline betting is learning how to read the lines. Bettors will usually see a + and a – amount after the listed teams. The – indicates the favoured team. Let’s say there is a moneyline of +120 and -130. The -130 is the favoured team and will cost $130 in bets to collect $100 on a win. If punters choose to bet the underdog at +120, they will bet $100 and will win $120. Basically, one will have to wager more on the favoured team to come out ahead.
Understanding NFL betting lines is just the first step towards making profits with football wagering. Once you've got the basics down, it's important to continue learning sports betting strategy to improve your long-term chances of winning. If you're able to win more than 52.4% of the time, you'll be well on your way towards being a profitable NFL bettor.

You don’t have layers of complexity to fight through to see if your prediction is a positive expected value move (one that is going to make you money). With some simple mathematical calculations, you can figure out whether or not there is value in a bet. Even if you don’t like math and would prefer not to use it when assessing value and making your picks, it’s still much easier to “eyeball” value with moneyline bets because of the simplicity.
As you might guess, you’re mainly going to see American odds in American sportsbooks. The other two formats are much more prominent in Europe and Asia. If you’re betting online, most sportsbooks give you the ability to change all of the odds on the site into the format that you prefer. No format is different regarding payouts; it’s just a different way of presenting the information.
Moneyline parlays are growing in popularity. A parlay is a single wager that is comprised of multiple results. The payout for a parlay is greater than an individual wager on each player or game. Underdog moneyline parlays are becoming popular because the payouts can be very large. Moneyline parlays are becoming popular because of the perceived ease of choosing multiple favorites to win. Choosing one winner is difficult and multiple winners at the same time is even more difficult.
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.
What may look like a jumble of words, numbers, and punctuation is actually a precise and easy-to-read breakdown of the various odds and point spread details your book is offering. Here is a breakdown of each unit of information given above. Once you understand each part of the jumbled details above, you’ll be able to read a sports betting line with confidence.
In the United States, most bookmakers use the moneyline format to express the odds they offer for wagers. Thus, moneyline odds are also commonly referred to as American odds. They can be either a positive number or a negative number. A positive number shows how much profit a winning wager of $100 would make, while a negative number shows how much needs to be staked to win $100.
Spreads are frequently, though not always, specified in half-point fractions to eliminate the possibility of a tie, known as a push. In the event of a push, the game is considered no action, and no money is won or lost. However, this is not a desirable outcome for the sports book, as they are forced to refund every bet, and although both the book and its bettors will be even, if the cost of overhead is taken into account, the book has actually lost money by taking bets on the event. Sports books are generally permitted to state "ties win" or "ties lose" to avoid the necessity of refunding every bet.
