Brazil's Série B is the country's second-division football league, featuring 20 clubs competing across 38 matchdays in a full round-robin format. The season typically runs from April through November, and it delivers a betting landscape that differs meaningfully from the more heavily scrutinized Série A. Scoring tends to be moderate, with matches averaging roughly 2.2 to 2.5 total goals, though the variance is notable — the quality gap between promotion contenders and relegation-threatened sides can produce lopsided results. Home advantage is a significant factor in Série B, often more pronounced than in top-flight Brazilian football, partly due to long travel distances across a continental-sized country and the passionate, sometimes intimidating atmospheres at smaller regional grounds.
Vig on Série B markets tends to run wider than what bettors find on Série A or major European leagues. Because bookmakers have less modeling confidence in a division with higher squad turnover, less comprehensive data, and more unpredictable form lines, they build in larger margins as a hedge against uncertainty. Three-way match result markets commonly carry margins in the 5–8% range, though this varies significantly across sportsbooks. Comparing vig across books becomes especially valuable here, as the spread between the sharpest and softest lines can be substantial — sometimes representing several percentage points of built-in edge that bettors are needlessly giving away.
Odds tend to be most competitive during the opening weeks of the season, when bookmaker attention is fresh and early-season narratives drive market interest. The sharpest vig opportunities often emerge mid-season, when public attention drifts and some books are slower to adjust lines to emerging form. Key factors that move Série B odds include squad depth — clubs frequently rotate or lose players to Série A teams mid-season — along with managerial changes, which happen at a notably high rate in Brazilian football. Weather can also play a role, as winter months in southern Brazil bring cooler, wetter conditions that can suppress scoring and favor more defensive, organized sides. Bettors who track these dynamics closely can find genuine informational edges in a market that remains underserved by mainstream analysis.

Frequently Asked Questions
Which sportsbook has the lowest Brazil Série B vig?
Pinnacle currently has the lowest vig at 4.45%, earning a grade of B.
What is vig (vigorish) in sports betting?
Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.
How often is this data updated?
We pull fresh odds from The Odds API three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.
How is the vig grade calculated?
Each sportsbook is graded on a letter scale based on average vig: A+ (under 2%) is exceptional, A (2–3%) is excellent, B+ (3–4%) is above average, B (4–5%) is the industry standard, C (5–6%) is below average, and D (above 6%) indicates high-juice markets.
Why does lower vig matter for bettors?
Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.
What sportsbooks do you track?
We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnySports). Data comes from The Odds API, which aggregates real-time lines from licensed sources.
How We Calculate These Numbers
- Data Source
- All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
- Update Frequency
- We pull a fresh snapshot of every tracked market three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
- Vig Calculation
- Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
- Per-Market Breakdown
- We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
- Grading Scale
- Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exchange-level pricing. A (2–3%) is very competitive. B+ (3–4%) is above average. B (4–5%) is the industry standard — a -110/-110 line is 4.76%. C+ (5–6%) is slightly below average. C (6–7%) is below average. D (7–8%) is high vig. D− (8–10%) is very high vig. F (10%+) is predatory pricing. See the full Vig Index Methodology for formulas, worked examples, and known limitations.
- Trend Tracking
- We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
