Overall Vig
D- · Rank #18 of 18
Fliff occupies a unique niche in the U.S. sports betting landscape, operating as a social sportsbook that uses a sweepstakes model rather than traditional real-money wagering. This structure allows Fliff to be available in a much wider range of states than conventional licensed sportsbooks, giving users in markets without full legal sports betting a way to engage with real odds and lines. Players use Fliff Coins (play money) and Fliff Cash (redeemable currency) under a sweepstakes framework, which keeps the platform within regulatory boundaries without requiring state-by-state sports betting licenses.
Fliff's primary strength is accessibility — it's available on both iOS and Android, offers a clean interface, and covers a solid range of major sports and bet types including spreads, moneylines, totals, and parlays. The app has improved steadily since launch, and its odds are generally competitive enough to benchmark against traditional books. However, the sweepstakes model introduces friction that seasoned bettors may find limiting. Withdrawal processes, currency conversions, and promotional structures differ significantly from what sharp or high-volume bettors expect from a DraftKings or FanDuel. Limits and liquidity also don't match what regulated books offer, and the overall depth of markets — particularly for niche sports, live betting, and player props — trails behind the top-tier competition.
Fliff is best suited for casual and recreational bettors, particularly those in states where mainstream sportsbooks haven't yet launched. It provides a legitimate way to engage with sports betting mechanics and real odds without needing to turn to offshore options. For experienced bettors shopping for the sharpest lines or highest limits, Fliff won't be a primary destination — but as a supplementary platform or entry point for newer users, it fills a genuine gap in the market.

Frequently Asked Questions
How good are Fliff odds?
Fliff has an average vig of 9.28%, earning a grade of D-. They rank #18 out of 18 tracked sportsbooks.
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.
