Bally Bet and theScore Bet represent two distinct paths into the US sports betting market, each backed by a major media or entertainment parent company. Bally Bet is tied to Bally's Corporation, which leveraged its casino and regional sports network branding to launch a sportsbook aimed at casual bettors already familiar with the Bally Sports ecosystem. theScore Bet, acquired by Penn Entertainment in 2021, grew out of one of North America's most popular sports media apps, giving it a built-in audience of engaged, stats-savvy sports fans. That difference in origin shapes each product: Bally Bet leans on its casino crossover appeal and retail presence, while theScore Bet was designed from the ground up as a mobile-first betting experience deeply integrated with sports content and data.
Bettors who value a seamless, content-rich mobile interface will generally find theScore Bet more polished. Its app was refined over years as a standalone sports news platform before betting was layered in, resulting in a notably smooth user experience with live scores, stats, and bet slip functionality woven together. Bally Bet, by contrast, has had a rockier rollout with a more limited state footprint and an interface that has drawn mixed reviews. However, bettors in states where Bally Bet operates may find value in its promotional offers tied to Bally's casino loyalty programs, which can be meaningful for anyone who frequents Bally's properties.
Beyond vig — which the live data on this page tracks in real time — bettors should weigh several practical factors. theScore Bet generally offers faster payouts and a more intuitive bet-building experience, while Bally Bet's limits and market depth have historically been narrower. Reliability matters too: theScore Bet benefits from Penn's significant infrastructure investment, while Bally Bet has faced occasional technical growing pains. For sharp or high-volume bettors, theScore Bet is typically the stronger choice; for casual bettors already in the Bally's ecosystem, the loyalty perks may tip the balance.
Vig Comparison by Sport
Frequently Asked Questions
Is Bally Bet or theScore Bet better for odds?
Bally Bet currently offers lower vig overall. Bally Bet averages 6.43% vig (C) while theScore Bet averages 7.06% vig (D).
How does Bally Bet compare to theScore Bet by sport?
We compare both books across 71 sports. The comparison covers vig percentages, grades, and which book offers better odds per sport.
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 exceptional and rare — these are typically sharp-friendly books. A (2–3%) is excellent. B+ (3–4%) is above average. B (4–5%) is the industry standard for most recreational sportsbooks. C (5–6%) is below average. D (above 6%) indicates high-juice markets where bettors face a steep cost per wager.
- 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.
