The odds for each card are the same. But in horse racing betting, for example, the odds vary, depending on factors such as the horse, jockey, conditions, trainer and many other variables. That’s why bookmakers set different odds for different outcomes, based on the probability of that outcome eventuating. Betting odds and probability. Take the example; if you bet $15 on a horse with 3/5 odds, the payout would be $24. The equation looks like this: $15 x 15 x 3/5. How Do Betting Odds Work in Sports Betting? If you’re betting on sports, Moneyline bets concern which team or player will win the game. The odds are either presented as a positive or negative number.

A point spread in sports is a way for oddsmakers to make a matchup between two unbalanced teams more balanced by giving points to or taking points away from each team. Point Spreads Explained The point spread is probably the most common bet when you think of wagering on a single sporting event. That is because it's designed to bring the two teams to an even playing field through the use of a handicap installed by oddsmakers.

Easily the most popular type of betting for NFL football is “spread” betting or more commonly known as betting against the spread. Bettors who are new to NFL betting or betting in general may be a little confused with NFL spread betting, but it is pretty easy to understand once it is explained to you. We will explain what betting against the spread means below.

What is Betting Against The Spread?

For each NFL game the oddsmakers set a number of points in which the favored team is favored by. Bettors can then either choose for the favored team to win by more than the number of points set, or bet on the underdogs to lose by less than the number of points they are underdogs by or win the game straight up. For example, the spread could be set on the favored team at 6.5 points. This would mean in order for a bet on the favored team on the spread to win they would need to win by more than 6.5 points (7 or more) in order to win the bet. It also means that a bet on the underdog team would win if the underdogs lost by less than 6.5 points (6 or less) or won the game outright.

Example of NFL Spread Bet

Below is an example of what NFL spread betting would look like:

Matchup

• TeamsSpread
• Dallas Cowboys -2.5
• New York Giants +2-5

The negative (-) sign indicates that the Cowboys are the favorites, while the positive (+) sign indicates that the New York Giants are the underdogs. With the spread set at 2.5 points, a bet on the Cowboys would mean that they would have to win by more than 2.5 points (3 or more) in order for you to win that bet. A bet on New York would mean that the Giants would have to either lose by 2.5 or less points (2 or less) or win the game outright in order for your bet to win.

Here is another example with a screenshot taken from 5Dimes.eu during Week 3 of the 2013 NFL season:

Here you can see that the Rams are +3.5, while the Cowboys are -3.5. So for this example the Cowboys are 3.5 point favorites, while the Rams are underdogs of 3.5 points. If you were to bet on St Louis you would need them to lose by 3 or fewer points or just win the game outright. If you were to bet on Dallas you would need the Cowboys to win by 4 or more points.

If the Cowboys were to win by 3 points, lets say 30-27, any bets on the Rams +3.5 would win. Even though the Rams didn’t win the game they covered the spread of 3.5 points.

Now if the Cowboys were to win by 4 points, lets say 31-27, the Cowboys have covered the spread and anyone who wagered on Dallas would win their bets.

Other NFL Spread Betting Information

You may often notice that the spread is sometimes set at an even number such as 3, 6 , 10, etc. In this case if the favored team won by the exact amount set for the spread the bet would be pushed, and all bets would be returned. For example, if the Patriots were 3 point favorites and they won by a FG (3 points) than this would results in a push, meaning no matter which side you bet on you would get your money returned to you.

The most common NFL spreads are usually set between about 2.5-10.5 points, but you will also almost always have games each week with spreads lower than 2.5 and higher than 10.5. In the event that the oddsmakers feel the game doesn’t need a spread, it would be set at 0 or what some call a pick’em (both teams are given even odds to win for this type of bet).

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.

Understanding the different types of betting options is crucial when you’re getting a start as a first-time sports bettor.

The Point Spread: Betting the spread

For those new to sports betting, the point spread is the simplest, most straightforward approach to placing wagers.

Sports books set a predetermined margin of points on a game and a team must win – or not lose – by that set number. That’s why you’ll often hear people say the team won, but they “didn’t cover the spread” so their bet still came up short.

It’s not a matter of a team winning or losing like in a moneyline bet.

For a favorite: The favorite must win by more than the point spread.For an underdog: The underdog must outright win OR lose by fewer than the point spread.

Gambling Point Spread Explained Spread

Sports books aren’t in the business of predicting who will win or lose games. Their goal is setting a pre-game point spread with the intention to generate an equal amount of betting action/volume on both sides of the ledger – as much total money being bet on the favorite as on the underdog.

The vast majority of point spread wagers are made on football and basketball because of the proliferation of points that are scored in comparison to sports like baseball and hockey, where 1-0 or 2-1 games aren’t that out of the question or out of the norm. There’s one every night.

For example, the New England Patriots are playing the New York Jets and New England is a 9½-point favorite. Bettors typically have to spend $110 or so to win $100 with sports books, known as “the house edge/advantage.” With a point spread bet, simply having a team win the game isn’t the key. The critical factor to betting a point spread is how much a team wins or loses by. If a wager is placed on New England – “laying” the 9½ points – the Patriots need to win the game by 10 or more points for that bet to pay off. If New England wins 28-20, those betting on the Jets plus 9½ points (points added to their final total) win the bet.

The same general rules apply for basketball and are quite easy to follow because of the inherent simplicity of the bet. When it comes to betting sports like baseball and hockey, the standard bets are made on the “money line” – an established number for both teams to win the game outright.

What makes point spread bets attractive are the fluid nature of each game – it’s a reality show that, when done right, is inexplicable. Games change on one play and momentum is a thing. But, when it comes to point spread betting, you know where you stand at every moment.
