Totals (Over/Under) Betting
A total — also called an over/under — is a wager on the combined score of both teams. You're not picking a winner; you're betting on whether the game will be high-scoring or low-scoring relative to the posted number.
How Totals Work
The sportsbook posts a number (e.g., 226.5 for an NBA game) and offers both sides at –110:
- Over 226.5 — combined score must be 227 or higher
- Under 226.5 — combined score must be 226 or lower
Oregon Example: Trail Blazers vs. Warriors Total 230.5
Say the Trail Blazers host Golden State at the Moda Center, total set at 230.5. If the final is Blazers 118 – Warriors 116 (combined 234), the over cashes. Final of 115–114 (229) → under cashes.
Soccer Totals
In soccer (e.g., Portland Timbers matches), totals are nearly always set at 2.5 goals — the average MLS game scores 2.8 goals. Sub-options include "team totals" (just one team's goals), exact-score variants, and 1st-half / 2nd-half totals.
What Moves Totals
- Pace: NBA games between two fast-paced teams (high possessions per game) have higher totals
- Defense ratings: Top defenses systematically push totals down 4–8 points in the NBA
- Weather (NFL): Wind >15 mph and heavy rain reduce passing yardage, pushing totals down
- Injuries: A missing star scorer drops a total; a missing star defender raises it
- Officiating crews (NFL/NBA): Some refs call more fouls/penalties, indirectly affecting scoring
Live Betting Totals
Live (in-game) totals adjust constantly. A high-paced first quarter inflates the line — but mean reversion is a real factor. Bettors who model "expected pace" can find value when first-half scoring blows past projection but second-half regression is likely.
Common Mistakes
- Auto-betting "over" because it's more fun — public has a known over bias; the under historically holds slight edge in the NBA
- Ignoring pace-adjusted stats — points per game alone is misleading without possessions
- Forgetting overtime — NBA overtime affects totals dramatically; some books have OT-excluded variants
- Weather as binary — light rain has minimal effect on NFL totals; wind >20 mph has heavy effect
