BetOnline.ag is one of the most established offshore sportsbooks serving U.S. bettors, having operated since the early 2000s. As an offshore book based in Panama, it falls outside the jurisdiction of U.S. state regulators, which means bettors don't have the same consumer protections they'd find with state-licensed operators. That said, BetOnline has built a long track record of processing payouts and maintaining operational stability, which has earned it a generally reliable reputation within the offshore space — though it hasn't been without controversy, including past allegations of questionable line movements and poker integrity issues that the company has since addressed.
Where BetOnline stands out is in its breadth of offering. The sportsbook covers a wide range of markets, including niche sports, esports, and entertainment props that many domestic books don't touch. It also posts lines early compared to competitors, accepts cryptocurrency deposits and withdrawals, and offers reduced juice on certain markets. For bettors who value access and variety, these are meaningful advantages. On the weaker side, BetOnline's odds aren't always the sharpest — lines can lag behind market-leading books, and limits on sharp bettors tend to tighten quickly. The user interface, while functional, doesn't match the polish of top-tier regulated sportsbooks, and customer support can be inconsistent.
BetOnline is best suited for recreational to mid-level bettors who want broad market access without the geographic restrictions of state-regulated books. It's a solid option for bettors in states without legal sports betting, those who prefer crypto transactions, or anyone looking to shop lines across both offshore and domestic options. High-volume sharps may find better value and higher limits elsewhere, but for everyday bettors seeking convenience and coverage, BetOnline remains a competitive choice in the offshore tier.

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 every hour, on the hour (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 average vig: A+ (under 2%) is exchange-level pricing, A (2–3%) very competitive, B+ (3–4%) above average, B (4–5%) the industry standard, C+ (5–6%) slightly below average, C (6–7%) below average, D (7–8%) high vig, D− (8–10%) very high, F (10%+) predatory.
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, BetAnything). 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 every hour, on the hour (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.
