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

  1. 1
    Leg 1 — Celtics ML −180 (fair: −168)
    Edge: −1.5% — graded C.
  2. 2
    Leg 2 — Tatum 28+ pts +125 (fair: +110)
    Edge: +3.6% — graded A−.
  3. 3
    Leg 3 — Game Over 218.5 −115 (fair: −108)
    Edge: −1.6% — graded C.
  4. 4
    Leg 4 — Lakers +6.5 −110 (fair: −106)
    Edge: −0.9% — graded C+.
  5. 5
    Blended slip edge: −0.4%
  6. 6
    Slip grade: C
    Leg 2 is sharp; legs 1, 3, 4 erase the edge. Take Leg 2 as a single.
Most parlays are one or two good legs surrounded by filler. The analyzer surfaces the real bet — usually the sharpest leg as a straight wager — instead of letting vig compound across the slip.

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.
