Meaning of Over 170.5 in Basketball Betting
“Over 170.5” refers to a total points bet (also called Over/Under or Totals).
You are betting on the combined total points scored by both teams in a game.
- If both teams’ total score is 171 points or more, your Over 170.5 bet wins.
- If the total score is 170 points or fewer, your bet loses.
The “.5” means there is no possibility of a tie (no push).
Example Game
Let’s take an example from the NBA:
Game: Golden State Warriors vs Sacramento Kings
Total Line: 170.5 points
You bet Over 170.5.
Possible Outcomes:
| Final Score | Total Points | Result for Over 170.5 |
|---|---|---|
| Warriors 92 – 85 Kings | 177 | Win |
| Warriors 88 – 84 Kings | 172 | Win |
| Warriors 86 – 83 Kings | 169 | Lose |
| Warriors 90 – 80 Kings | 170 | Lose |
You win if the total = 171 or more
You lose if the total = 170 or fewer
How Sportsbooks Set 170.5
A line like 170.5 is common in:
- Defensive leagues or tournaments (e.g., EuroLeague or FIBA)
- Early NBA seasons where teams are adjusting
- Games with slower tempo teams
It shows the bookmaker expects a moderately low-scoring game, compared to the NBA average total of around 220+.
Team Example: Denver Nuggets
Let’s look at the Denver Nuggets, a balanced team with strong defense but efficient offense.
- When playing a defensive team (like the Miami Heat), the total line may be around 170.5 – 175.5.
- When playing a fast-paced team (like the Golden State Warriors), the line may rise above 230.5.
So, if Denver is facing another defensive team, the line at 170.5 suggests both are likely to keep a slower pace, focusing on ball control and half-court sets.
Betting Tip
Here’s how to approach Over 170.5:
- Check Team Pace:
- Bet the Over if both teams play fast, shoot a lot of threes, or average 85+ possessions per game.
- Example: Golden State Warriors vs. Indiana Pacers → likely to go Over.
- Review Recent Form:
- If both teams’ last 5 games averaged 175+ points total, Over 170.5 has good value.
- Avoid Over in Defensive Matchups:
- Games like Miami Heat vs. Minnesota Timberwolves often stay Under because of slow tempo and tight defense.
- Injury Watch:
- Missing key scorers (like Jokic, Curry, or Tatum) can make the Under more likely.
Example Betting Scenario
Bet: Over 170.5
Game: Milwaukee Bucks vs. Cleveland Cavaliers
Your Stake: $100
Odds: 1.90
- If the final score is Bucks 92 – 86 Cavaliers (178 total) → You win $190 (profit $90)
- If the final score is Bucks 85 – 82 Cavaliers (167 total) → You lose $100
