Bally Bet is a fully regulated US sportsbook backed by Bally's Corporation, one of the oldest and most recognizable names in the American casino industry. Launched as part of Bally's broader push into digital sports betting, the platform operates in a handful of states and has positioned itself as a challenger brand in a market dominated by DraftKings, FanDuel, and BetMGM. Its ties to Bally's brick-and-mortar casino portfolio give it a foundation of legitimacy, but the sportsbook has struggled to carve out significant market share since its debut.
In terms of strengths, Bally Bet benefits from its integration with the Bally Rewards loyalty program, which appeals to bettors who also frequent Bally's casinos and want to earn cross-platform perks. The interface is clean enough for standard wagering, and the book covers major US sports adequately. However, the weaknesses are notable. The odds are generally not as competitive as those offered by larger operators, the betting menu lacks the depth found on platforms like FanDuel or BetRivers — particularly for props, alt lines, and niche markets — and promotional offers tend to be modest. The app has also received mixed reviews regarding speed and reliability, areas where more established competitors have invested heavily.
Bally Bet is best suited for casual, recreational bettors — particularly those already loyal to the Bally's casino ecosystem who value the convenience of a single rewards account. Sharp or high-volume bettors will likely find the limited market depth and less competitive lines to be significant drawbacks. As a sportsbook, Bally Bet is a legitimate, regulated option, but it currently operates as a tier-two product in a crowded field where the top books set a high bar for user experience and pricing.

Frequently Asked Questions
What is Bally Bet's average vig?
Bally Bet has an overall average vig of 6.04%, earning a grade of C. They cover 24 sports.
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.
