Odds on Deck
Data-driven sports betting analytics
We scan odds from every major sportsbook in real time, identify where the lines are off, and surface the bets where you have a mathematical edge. No gut feelings, no hype — just numbers.

Transparent results
Every prop we surface gets tracked. After the game ends, we pull the actual stats and record whether the prediction hit or missed. No hiding bad picks.
What makes this different
Most tools show you odds. We show you where the odds are wrong.
Line Shopping Engine
We compare odds across 10+ sportsbooks simultaneously. When one book posts a line that's out of step with the market, we flag it as an opportunity.
Edge Detection
Every prop is analyzed for its implied probability vs. the true market probability. Positive edge means the payout exceeds the actual risk.
Quality Scoring
Not all edges are equal. Our quality score weighs edge size, book count, line consensus, and market confidence into a single actionable number.
Validated Track Record
We track every prediction against actual results. Our validation system shows real win rates and ROI — no cherry-picked screenshots.
Strategy Filters
Filter props by betting strategy — sharp value, high confidence, balanced approach, or long shots. Match the data to your style.
Parlay Generator
Build parlays from our highest-quality props with correlated picks and calculated combined odds. See exactly what you're betting on.
How it works
We pull today's games from ESPN and league APIs
Every morning, we fetch the full slate — schedules, probable pitchers, matchup data — for MLB, NHL, and NFL.
Live odds are scraped from 10+ sportsbooks
Moneylines, spreads, totals, and 10+ player prop markets are pulled from The Odds API. We see what DraftKings, FanDuel, BetMGM, BetRivers, and others are posting.
The engine calculates edges and quality scores
For each prop, we remove the vig, calculate the true implied probability from the market consensus, and compare it to each book's posted line. The difference is your edge.
Top picks surface to the top
Props are ranked by quality score — a composite of edge size, number of supporting books, and market agreement. The best opportunities appear first.
Results are validated against actual stats
After games finish, we pull box scores from official league APIs and check every prediction. Win rate, ROI, and units are tracked over time with full transparency.
Key concepts
Understanding these terms will help you get the most out of the data.
- Edge
- The percentage difference between the true probability and what the sportsbook is offering. A positive edge means the bet pays more than it should.
- Example: If the true probability is 55% but the book implies 48%, you have a +7% edge.
- Implied Probability
- The break-even win rate embedded in the odds. American odds of -110 imply ~52.4% — you need to win more than that to profit long-term.
- Example: +150 odds imply 40% probability. If the true chance is 50%, that's a value bet.
- Vig (Juice)
- The sportsbook's built-in margin. Both sides of a bet add up to more than 100%. We strip the vig to see the true market probability.
- Example: -110 on both sides = ~104.8% total. The extra 4.8% is the book's cut.
- Quality Score
- Our composite metric (0-10) that combines edge size, number of books offering the line, market consensus, and implied probability. Higher is better.
- Scores above 7 indicate strong agreement across books with meaningful edge.
- Line Shopping
- Comparing the same bet across multiple sportsbooks to find the best price. A half-point or +10 in odds compounds over hundreds of bets.
- Player Over 2.5 hits might be -130 on DraftKings but -110 on BetRivers.
- Win Probability
- Our estimated chance the bet wins, derived from the vig-removed market consensus. Higher probability = more likely to hit, but usually lower payout.
How to use this
A few approaches depending on your style.
Conservative: High-Confidence Singles
Go to Player Props and filter by High Confidence. These are props where multiple books agree on the line and the edge is moderate but consistent. Place straight bets on the top 3-5 picks. Win rate tends to be highest here.
Balanced: Quality Score Ranking
Use the default Best Value sort on the Props page. This balances edge and confidence. The top 10 props by quality score represent the best risk-adjusted opportunities on the board. Mix singles and small parlays.
Aggressive: Sharp Value Hunting
Filter by Sharp Value to find props with the largest edges. These may have lower win probability but the payout more than compensates. Use the Parlay Generator to combine 2-3 of these for bigger payouts. Expect more losses but larger wins.
