Analyze my parlay
Upload your slip — single sport or cross-sport, traditional or same-game parlay — and get per-leg A–F grades, fair odds, edge %, and a plain-English verdict on the whole ticket.
Why parlays need analysis
A single bet at −110 / −110 carries about 4.5% vig against you. Three legs of the same market structure stack to roughly 14%. Five legs push past 20%. Same-game parlays add correlation pricing on top — that's how a 6-leg SGP at +1200 can be priced as if it should be +2400.
The analyzer treats every leg individually so you can see exactly where the value sits — and which legs are silently bleeding the slip.
Worked example — a 4-leg NBA parlay
- 1Leg 1 — Celtics ML −180 (fair: −168)Edge: −1.5% — graded C.
- 2Leg 2 — Tatum 28+ pts +125 (fair: +110)Edge: +3.6% — graded A−.
- 3Leg 3 — Game Over 218.5 −115 (fair: −108)Edge: −1.6% — graded C.
- 4Leg 4 — Lakers +6.5 −110 (fair: −106)Edge: −0.9% — graded C+.
- 5Blended slip edge: −0.4%
- 6Slip grade: CLeg 2 is sharp; legs 1, 3, 4 erase the edge. Take Leg 2 as a single.
Frequently asked questions
How does a parlay analyzer work?+
A parlay analyzer breaks your multi-leg bet into individual legs, prices each leg against the live market, devigs the consensus, and tells you which legs add edge and which legs drain it. The output is a per-leg grade plus a blended slip grade.
Why do parlays lose more often than singles?+
Sportsbook vig compounds across legs. A 3-leg parlay with three standard −110 / −110 markets carries roughly 14% built-in hold versus 4.5% on a single. Add same-game-parlay correlation pricing and the hold can climb past 25%. The analyzer surfaces this so you can drop the dead weight or take the legs as singles.
Can it analyze same-game parlays (SGPs)?+
Yes. SGPs are priced with correlation adjustments by the book, but the per-leg approach still flags which legs are sharply priced and which are giveaways. Most SGPs grade poorly because correlation is priced against you — the analyzer tells you when one is actually worth taking.
What's the difference between this and a parlay calculator?+
A parlay calculator does math: combined odds, payout, win probability. A parlay analyzer does judgment: it compares your slip's actual price to the fair market price and grades whether it beats the market.
Does it work with screenshots from DraftKings, FanDuel, BetMGM?+
Yes. Upload a screenshot from any major US sportsbook — DraftKings, FanDuel, BetMGM, Caesars, ESPN BET, Fanatics — and OCR pulls the legs and odds automatically.
