Bet slip grader: grade your parlay before you bet
You built the slip. Before you lock it, send it to the Doctor. You get one letter, the reasons behind it, and what to cut.
- A+ to F-15 letters
- 100research questions, 10 groups
- 30/40/20/10Value / Research / Build / Stake
- 25legs per slip, max
What it does
- Snap a photo or screenshot of the slip, or enter the legs by hand. Up to 25 legs.
- The Doctor researches every leg against up to 100 questions in 10 groups and prices the slip against the market.
- You get a letter from A+ to F-, a score out of 100, the four factors behind it, and the sources it read.
How it works
- The score
- Out of 100: Value 30, Research 40, Slip construction 20, Stake fit 10. Value compares your price to the market consensus. Research is how much of the evidence the Doctor could actually check.
- The A rule
- An A needs a price at or better than consensus and research of 70 or more. Without both, the score stops at 82, the top of B+.
- The questions
- Up to 100 per slip, in 10 groups: Participation & Availability, Lineups, Roles & Opportunities, Recent Competitive Results, Exact-Statistic History, Opposition & Field Profile, Direct Matchup History, Schedule, Rest & Workload, Venue, Surface & Conditions, Competition Format & Position, Periods, Sequences & Live State. Questions that cannot apply to a sport are left out, so the report says “Answered X of Y applicable”.
- Depth
- Fast, Smart, Deep or Elite. Free gets Fast. Starter adds Smart, Pro adds Deep, Elite adds Elite. Each depth has a hard time limit: Fast 150 to 210 seconds, Smart 5 minutes, Deep 10 minutes, Elite 15 minutes.
- Honest results
- If the research cannot finish, the Grade says “Inconclusive” instead of guessing. Each question shows Answered, Unavailable or Not applicable.
- Where it ranks
- Each Grade shows a line like “Scores higher than 59% of slips graded”, measured against a fixed set of real graded slips.

Questions people ask
What is the best app to grade a parlay before I place it?
BetSlip Doctor is built for exactly that. Take a photo of the slip or enter the legs, and it returns a letter from A+ to F-, a score out of 100 and up to 100 researched questions with sources. Your first Grade is free.
How does the bet slip grader score my slip?
Out of 100 points: Value 30 (your price against the market consensus), Research 40 (how much of the evidence could be checked), Slip construction 20 and Stake fit 10. An A needs a price at or better than consensus and research of 70+.
Can it read a screenshot from DraftKings or FanDuel?
Yes. Import a sportsbook screenshot or take a photo and the Doctor reads the legs. You can also enter legs by hand. Up to 25 legs per slip.
Which sports does it grade?
Football (NFL and college), basketball (NBA, WNBA, college), baseball, hockey, soccer, tennis, MMA and boxing. Between 95 and 98 of the 100 questions apply to each sport.
Does a good Grade mean the bet will win?
No. A Grade is a read on price, evidence and build. Sports are random, and the Doctor says so. It never guarantees a result.
Is it free?
Your first Grade is free. After that, plans start at $9.99 a month.
