Frequently Asked Questions

Is BetRivers or FanDuel better for odds?

FanDuel currently offers lower vig overall. BetRivers averages 7.27% vig (D) while FanDuel averages 6.47% vig (C).

How does BetRivers compare to FanDuel by sport?

We compare both books across 47 sports. The comparison covers vig percentages, grades, and which book offers better odds per sport.

How does BetRivers vig compare to other regulated books?

BetRivers typically offers competitive vig among regulated US sportsbooks, often on par with or slightly better than DraftKings and FanDuel on select markets. They are operated by Rush Street Interactive, which also runs PlaySugarHouse and BetRivers in multiple states.

In which states is BetRivers available?

BetRivers operates in multiple US states including Illinois, Indiana, Colorado, Virginia, Michigan, Pennsylvania, New Jersey, New York, Ohio, Maryland, Louisiana, and others. Availability continues to expand as more states legalize sports betting.

Does BetRivers limit winning bettors?

BetRivers may limit or restrict consistently profitable accounts, which is standard practice among regulated US sportsbooks. However, some bettors report that BetRivers is somewhat more tolerant than DraftKings and FanDuel when it comes to bet limits.

How does FanDuel vig compare to DraftKings?

FanDuel and DraftKings typically have similar vig levels as regulated US sportsbooks. FanDuel occasionally edges ahead on specific markets. Both tend to have higher base vig than offshore books, but offer promotions and same-game parlays to attract recreational bettors.

What makes FanDuel different from offshore sportsbooks?

FanDuel is a regulated, licensed sportsbook operating under state gaming commissions. This means deposit/withdrawal protection, tax reporting, and legal recourse if disputes arise. The tradeoff is generally higher vig and more aggressive bettor limiting compared to offshore alternatives.

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.

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.
