MyBookie.ag is an offshore sportsbook based in Curaçao that has carved out a recognizable presence in the U.S.-facing market, largely through aggressive marketing and promotional campaigns. It is not licensed or regulated by any U.S. state gaming authority, which means bettors do not have the same legal protections or dispute resolution mechanisms available through domestically regulated books. Despite this, MyBookie has maintained a sizable user base since its launch in 2014, appealing primarily to recreational bettors drawn in by sign-up bonuses and a broad menu of betting options spanning major North American sports, esports, politics, and entertainment props.

On the strengths side, MyBookie offers a wide variety of markets and prop bets, often posting lines on niche events that some domestic books skip entirely. Their interface is straightforward, and they tend to be early with lines on certain markets. However, the weaknesses are notable. Odds frequently lag behind sharper offshore and domestic competitors, meaning bettors are often getting worse numbers. Withdrawal processes have drawn consistent criticism — payouts can be slow, and bonus rollover requirements are among the most aggressive in the industry, often trapping deposited funds behind playthrough conditions that casual bettors don't fully understand before opting in. Reports of limited accounts or reduced limits for consistent winners suggest the book is firmly oriented against sharp action.

MyBookie is best suited for casual, low-volume bettors who prioritize market variety and promotional offers over line quality and payout speed. Serious bettors, high-volume grinders, or anyone shopping for the sharpest numbers will generally find better value elsewhere. Its reputation is mixed — functional and reliable enough for small-stakes recreation, but lacking the transparency and efficiency that more demanding bettors expect from a primary sportsbook.

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.
