Over/Under, also known as totals betting, is a hugely popular form of sports wagering. Instead of predicting who will win, you’re betting on whether the total combined score of a game will be over or under a number set by the sportsbook. This guide breaks down everything you need to know.
How Over/Under Betting Works
The sportsbook sets a line – a predicted total score for the game. For example, in an NBA game, the line might be 220.5. You then have two options:
- Over: You bet that the combined final score of both teams will be more than 220.5.
- Under: You bet that the combined final score will be less than 220.5.
The “.5” is crucial. It eliminates the possibility of a “push” (tie), ensuring a definitive win or loss. A score of 221 would win an Over bet, while 220 would win an Under bet.
Example Scenarios
Basketball (NBA/NCAA)
Line: 215.5
- Final Score: Team A 108, Team B 102 (Total: 210) – Under wins.
- Final Score: Team A 110, Team B 108 (Total: 218) – Over wins.
Football (NFL/NCAA)
Line: 45.5
- Final Score: Team A 28, Team B 17 (Total: 45) – Under wins.
- Final Score: Team A 24, Team B 22 (Total: 46) – Over wins.
Understanding Odds & Payouts
Over/Under bets typically have odds of -110. This means you need to bet $110 to win $100 (plus get your $110 back). Odds can vary based on the sportsbook and the amount of money wagered on each side. You might see odds like -105, -115, or even +100 (even money).
Factors to Consider
- Team Scoring Trends: How many points do these teams typically score?
- Defensive Strength: Strong defenses tend to keep scores lower.
- Pace of Play: Fast-paced teams generally lead to higher scores.
- Injuries: Key player injuries can significantly impact scoring.
- Weather (Football): Bad weather often leads to lower-scoring games.
- Historical Data: Look at past matchups between these teams.
Strategies for Over/Under Betting
Research is key. Don’t just blindly pick over or under. Analyze the factors above. Shop for the best lines. Different sportsbooks will offer slightly different lines, potentially increasing your payout. Consider situational factors like travel schedules and back-to-back games.
Common Mistakes to Avoid
- Ignoring the .5: Remember the .5 eliminates pushes.
- Betting based on emotion: Stick to your research.
- Chasing losses: Don’t increase your bets to recoup losses.
