Point spread betting is a popular wager type for basketball games, especially when a dominant team plays a weaker opponent. It is a bet on the margin of victory of a particular game. Oddsmakers determine the point spread based on how competitive the game is likely to be. For example, if the point spread is 3 points, the favourite to win will be indicated with a minus number (-3) and the underdog will be given a plus number (+3). The point spread is usually posted around 24 hours before the game, and it is a good idea to shop around to find the best number as they can vary between sportsbooks.

Point spread betting basics
Point spread betting is one of the most popular bet types, especially for basketball games that often feature a dominant team against a weaker opponent. In its simplest form, the point spread levels the playing field in any game, regardless of the mismatch.
When deciding on a point spread for a particular game, oddsmakers consider several factors, including team strength, past performance, rest advantages, home court advantage, momentum, motivation, injuries, and more. Favorites (the perceived stronger team) are marked with a minus sign (-), while underdogs (the perceived weaker team) are noted with a plus sign (+) to indicate how many extra points a sportsbook is giving that team. For example, if the point spread is 3 points, you'll see that displayed as -3 for the favorite and +3 for the underdog.
When you look at odds, the date and time, the rotation number, and the team names establish the game on which you’re going to bet. The point spread, moneyline, and over/under are the three basic bets related to that game. These are the basics of any NBA odds listing that you need to know and understand before placing a wager.
In the NBA, odds are usually posted around 24 hours before tip-off but can be as late as the morning of the game. The best way to find market inefficiencies is to bet early before the numbers settle. That said, make sure to shop around and find the best number. Not all books are the same. Use an odds comparison tool to find the best price for your best.

How to read odds listings
Odds listings for basketball games can be confusing, but once you know what each number relates to, you'll be able to understand the odds for any game that's posted. Here's a step-by-step guide on how to read odds listings for basketball:
Understand the Basics of Point Spreads:
Point spreads are the most popular way to wager on basketball games. They level the playing field by giving points to the underdog and taking points away from the favourite, making the contest more even. The favourite is indicated by a negative value (-) and the underdog by a positive value (+).
Identify the Components of an Odds Listing:
An odds listing for a basketball game typically includes the date and time, rotation number, team names, point spread, moneyline, and over/under. These elements may have different names depending on the source, but they serve the same purpose. The rotation number is a unique identifier for each team, making it easy to place wagers.
Analyze the Point Spread:
The point spread is the number of points added or subtracted from a team's final score to determine the outcome of a wager. It is set by oddsmakers based on various factors such as team strength, recent performance, home-court advantage, and injuries. A positive point spread indicates how many points are added to the underdog's score, while a negative point spread indicates how many points are subtracted from the favourite's score.
Understand Moneyline and Over/Under:
The moneyline is a bet on which team will win the game outright, without considering the point spread. The odds for the moneyline are indicated by a positive or negative value, showing how much you can win or need to wager. The over/under, also known as the total, is a bet on whether the combined score of both teams will be over or under a specified number.
Timing and Movement:
NBA odds are typically posted around 24 hours before a game, but they can be subject to change. Odds see the most movement shortly after they are posted, so it's essential to monitor the market and place bets early if you want to take advantage of potential inefficiencies.
Consider Team Matchups and Form:
Look closely at how teams match up against their opponents, considering factors such as shooting form, injuries, and player availability. These factors can significantly impact the outcome of a game and, therefore, the accuracy of your wagers.
By following these steps and familiarizing yourself with the terminology and factors influencing odds listings, you'll be well on your way to making informed and strategic wagers on basketball games. Remember to always gamble responsibly and stay informed about the teams and odds before placing any bets.

The impact of team strength
Team strength is a key factor in determining point spread values in basketball betting. The point spread is the expected final score difference between two teams, and it is represented as both a negative and positive number. Favorites (the perceived stronger team) are marked with a minus sign (-) and underdogs (the perceived weaker team) are noted with a plus sign (+). The number of points indicated by the "+" or "-" sign represents how many extra points a sportsbook is giving that team. For example, if the point spread is -9 for the favorites and +9 for the underdogs, the favorites need to win by at least 10 points for a spread bet to win. If the favorites win by exactly 9 points, it is considered a "push," and both sides get their original wager back.
When determining a point spread, oddsmakers consider various factors, including team strength, past performance, and current form. They look at how teams match up against their opponents, taking into account strengths and weaknesses. For example, a team that struggles to defend on the perimeter is likely to have a harder time against an elite 3-point shooting team. Oddsmakers also consider injuries, as the availability of key players can significantly impact a team's performance and, consequently, the point spread.
In addition to team-specific factors, oddsmakers also look at broader considerations such as home court advantage. Playing at home can provide a significant advantage in basketball, and this is reflected in the point spread. The timing of when odds are posted can also be important. NBA odds are usually posted around 24 hours before a game, but they can be as late as the morning of the game. Betting early, before the numbers settle, can be a good strategy to find market inefficiencies.
It's worth noting that sportsbooks may not always set odds purely based on analytics. They may take a position, where they set the point spread in a way that requires a certain result for them to turn a profit. This can occur when a sportsbook feels that the public is likely to heavily back a particular team, putting them at risk of loss if that team covers the spread. As a result, some sportsbooks may adjust the point spread to make the favored team more attractive to bettors, thus balancing the betting action.

Home court advantage
Home-court advantage is a significant factor in the NBA, with teams consistently winning around 60% of their regular-season games in their home arenas. This advantage is reflected in point spread betting, which aims to level the playing field and make games more interesting for bettors.
When a team plays in their home court, they may experience a boost in performance due to the psychological impact of playing in a familiar environment with the support of their fans. This can lead to improved statistics, such as decreased turnovers, increased scoring, more fast-break points, and fewer fouls committed. However, it is challenging to determine precisely how much of a team's success is due to this psychological impact or referee bias.
The impact of home-court advantage on winning can vary from season to season and is not always consistent. For example, in the 2012 playoffs, home teams had a winning percentage of 65.4%, while in 2008, they achieved a winning percentage of 74.4%, the highest in 18 years.
When considering point spread betting, it is essential to examine how teams perform at home compared to on the road. Some teams may have a more substantial home-court advantage, while others may perform more consistently regardless of the venue. Oddsmakers will consider these factors when setting the point spread for a particular game, and bettors can use this information to make more informed wagers.
Additionally, bettors should look at the overall strength of the teams, recent performance, and individual player injuries when evaluating the impact of home-court advantage on point spread betting. By considering these factors, bettors can gain a better understanding of the potential outcome of a game and make more strategic betting decisions.

Understanding the vig
The vig, short for vigorish, is the amount charged by sports betting sites for taking a bet, also known as the juice in slang terms. It is the house edge, or how a sportsbook makes money. Sports betting sites need to turn a profit, so they work a slight advantage into each bet. The vig is included in the betting odds listed for a match or game.
The vig is the cut that the sportsbook takes when a bettor loses a wager. For example, a point spread is often listed with -110 odds. If the Eagles are -6.5-point favorites, that would be at -110 odds. If there was no vig, it would be at even odds, or +100. With the vig, a $100 bet would result in a $190 payout. If there was no vig, a $100 bet would result in a $200 payout. This means that if you want to win $100, you'd have to bet $110 because of the vig, and when the bet loses, that $10 goes straight to the sportsbook.
You can calculate the vig on a set of bets yourself using this formula: (Favorite odds / (Favorite odds + 100) x 100) + (100 / (Underdog odds + 100) x 100) – 100 = Vig.
Not all sports betting apps are the same, and sometimes regular odds are listed at -115 or -120. As more states legalize sports betting, the variety in vigs across states will differ. That's because a lot of in-person sportsbooks take a higher cut of bets than online sportsbooks, which receive more bets because they are more widely accessible. While each state has different rules, there are certain states where sportsbooks have a higher vig across the board, no matter where you wager.
You can use sportsbook promos like odds boosts to lower the vig and increase your potential payout. For example, the BetMGM bonus code ROTOSPORTS offers a first bet bonus of up to $1,500 and access to numerous odds boosts and ongoing promotions.
