Betting point-spreads and moneyline in basketball are exciting, but wagering on NBA Over/Unders betting may be the most popular among the three. 

Single-game score totals

When betting on game totals, also known as Over/Unders, bettors wager on whether the total combined score of a game will go Over or Under the sportsbooks’ set total. 

In the example below, the Grizzlies and Warriors’ total is listed at 228.5. Betting the Over here would mean you expect the game to total 229 points or more, while if you took the Under, you’d expect 228 points or fewer in the game.

For example, you would win the bet if the final score was 118-114 (232), and you bet the Over. If the score was 110-109 (219), you would lose.

Remember, who wins and by how much doesn’t matter. It’s about the number of points scored for single-game totals. 

Season win totals

Another way to bet on totals in the NBA is by season wins. Before the NBA season starts, sportsbooks will release individual team win totals. 

You’re wagering on how well a team will perform throughout the year, as opposed to how they would do in a single game. These lines will usually come out following free agency as teams’ rosters dramatically change during the offseason. 

In this example below, a sportsbook gave the Brooklyn Nets a season win total of 56.5 wins. Bettors would wager on whether they think the Nets will win Over or Under 56.5 games. 

Team Over Under
Brooklyn Nets 56.5 (+120) 56.5 (-150)
Milwaukee Bucks 55.5 (-110) 55.5 (-120)
Golden State Warriors 48.5 (-110) 48.5 (-120)
Los Angeles Lakers 53.5 (+140) 53.5 (-170)
Charlotte Hornets 38.5 (-110) 38.5 (-120)

The sportsbooks assign a “.5” to the odds so that it's impossible for the team to hit the exact total. Teams can’t win half a game, nor can they score half of a point in single-game totals. 

A second set of odds accompanies totals odds on sportsbooks, known as the vig or juice.

What is the vig/juice?

The juice (also known as the vig) is the price the sportsbook imposes when you place a wager on Over/Unders. For example, the juice on the Milwaukee Bucks' Over 55.5 team wins is -110. 

You would need to bet $110 to win $100, which would give the book a $10 profit. If there were no vig, the Bucks line would be +100. In that case, the vig would be 10 percent.

Sometimes sportsbook will change the vig on a win total. Suppose a lot of money is coming in on the Bucks Over 55.5 team wins at -110. In that case, the sportsbook will usually adjust the line to -120 or increase the total of 55.5. 

NBA Over/Unders tips, strategies

Now that you understand typical NBA Over/Unders odds, here are some tips to hone your basketball betting skills to make smarter NBA totals wagers.

Watch for trends Watch for trends

Check the upcoming slate of NBA games on our scores and matchups page. Look for trends on whether teams have a history of covering the Over or Under for the season. 

Knowing team pace is huge when betting basketball totals, as teams that slow the game down will more likely than not keep games low-scoring. 

Know the referees Know the referees

Referees can also heavily influence how a total plays out in calling fouls and sending players to the line. Some refs are stricter than others and quicker to make calls. It’s good to track who affects the Over or Under with their whistle.

Check Injury reports Check injury reports

If three-point threats Stephen Curry or Klay Thompson are out for the Warriors, there’s a good chance Golden State will have a more challenging time putting up points on the board. The NBA is star-driven, so one player getting hurt or taking a rest night for a matchup could affect a betting line in a significant way. 

You often won’t know the starting lineups until a few hours before tipoff, so it’s good to track daily injury reports.

Offense vs. defense Offense vs. defense

If two clubs are stingy defensively, that’s another sign that a game leans towards the Under. Conversely, if it’s a game between teams who shoot the lights out and don’t play great defense, target the Over. Many teams play each other numerous times throughout the season, so be sure to look back at the totals for previous contests. 

Usually, you’ll be able to find the tendency for whether or not matchups favor the Over or Under historically. Offenses and defenses run hot and cold for clubs throughout the season, so also make sure to research if guys are shooting the ball well in their last few games. 

Shop for the best lines Shop for the best lines

Creating more than one sports betting account is vital if you want to make money on the NBA. Not only can you take advantage of specific promotions and sign-up bonuses, but you can also find the best lines for the game. 

If a single-game total at one book is 219.5 but 221.5 at another at the same price, that is a huge difference. Two points may not seem like much, but Over/Unders usually come down to the wire for bettors and every bucket matters. 

When they first come out, the lines will be at their weakest and will get sharper as the game draws closer to start-time. That means the sportsbook will adjust the line due to particulars such as injury and lineup news.
