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

1

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.

2

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.

3

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.

4

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.

5

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.
