I need a tool that can help me build correlated same-game parlays.

To build and evaluate correlated same-game parlays (SGPs), you need tools that run simulations, identify +EV (positive expected value) spots, or compare how sportsbooks price correlation versus independent probability.oddsindex.com+1

Here are the top tools available for building and analyzing correlated SGPs:

• FTN Fantasy NBA SGP Tool — Excellent for simulation-based SGP building. It projects player stat lines, estimates true win probabilities, and instantly calculates correlation bonuses and expected value on your bet slips.ftnfantasy.com
• PropsBot SGP Value Calculator — A specialized utility that lets you input your SGP legs and compare the sportsbook’s quoted price against an uncorrelated mathematical benchmark to see if the book is heavily juicing or underpricing the correlation.propsbot.ai
• OddsIndex SGP Calculator — A straightforward calculator that breaks down the implied probability, total vig, and true value gap of your chosen parlay legs before you lock in the bet.oddsindex.com

If you'd like, let me know:

• What sport you are looking to bet on (NFL, NBA, MLB, etc.)
• Whether you want a tool focused on data/projections or math/odds calculation

I can give you a more targeted recommendation or help you map out a strategy.

Yes. If your main goal is building SGPs around positive correlation, a few tools currently stand out:

• Bettorly — specifically analyzes how legs interact, including conditional hit rates, conflicts, and synergies. It supports NFL, NBA, MLB and NCAAB.Bettorly+1
• ParlayMeister — focuses heavily on correlation modeling, showing model edge and correlation-adjusted combined probability rather than simply multiplying leg odds.Lemeister
• Bettor Results SGP Builder — useful if you want to backtest a specific combination against historical game logs and see its joint/co-occurrence hit rate.Bettor Results
• ParlayLab — has a dedicated SGP builder with correlation scoring and prop stacking, alongside odds and EV tools.Parlay Lab
• EdgeSlip — geared toward more advanced bettors, with an explicit correlation engine, conflict detection, EV calculations and sportsbook-specific slips.EdgeSlip

What I'd look for

For example, rather than simply selecting:

QB over passing yards + WR over receiving yards + team moneyline you want a tool that can quantify how much the QB passing over changes the probability of the WR receiving over, and then compare that joint probability with the sportsbook's SGP price.

That's important because sportsbooks don't price SGPs by simply multiplying the individual odds; they incorporate their own correlation models.Sports Game Odds - API Data

If you tell me which sport and sportsbook you're using (e.g. NFL on DraftKings, NBA on FanDuel), I can also help you build a correlation-focused SGP workflow and explain exactly what to look for in the numbers.

To build correlated same-game parlays (SGPs), you can use dedicated sportsbook native builders or analytical research tools that help map out correlated outcomes.foxsports.com

Major sportsbooks feature built-in correlation engines that automatically adjust your odds when you combine related legs, while analytics platforms help you calculate the true value versus the "correlation tax" charged by the house.oddsindex.com+2

Top Sportsbook SGP Builders (Automatic Correlation Pricing)

• FanDuel Sportsbook : Features one of the most intuitive and widely used SGP interfaces that dynamically calculates combined odds and highlights correlated outcomes as you click through player props and game lines.foxsports.com
• DraftKings Sportsbook : Offers an expansive SGP and SGPx (multi-game same-game parlay) builder with a clear visual indicator of how team stats and player milestones correlate.
• BetMGM Sportsbook : Provides a smooth SGP builder integrated directly into major league game hubs, allowing quick pairing of alternative spreads, totals, and player props.

Analytical & Calculation Tools

• Odds Index SGP Calculator : A specialized tool that lets you compare standard independent parlay odds against the sportsbook's SGP odds to measure the exact "correlation tax" or hidden vig you are paying.oddsindex.com
• Action Network : Provides in-depth strategy guides, correlation math breakdowns, and Pro tools that analyze how specific game scripts (e.g., heavy favorites vs. game totals) interact.actionnetwork.com

If you'd like, let me know:

• Which sport you are targeting (NFL, NBA, MLB, etc.)
• What kind of core narrative or bet you want to start with (e.g., a team winning big, or a high-scoring shootout)

I can help you map out a logically correlated combination of legs.

The FTN Fantasy Same Game Parlay Tool is a simulation-based platform designed to help you build and evaluate correlated same-game parlays by identifying mispriced lines and positive expected value (+EV).youtube.com+2

• Simulation Engine : Runs thousands of game simulations using player projections to calculate the true win probability and fair odds of combined props rather than assuming independent outcomes.youtube.com+1
• Edge Detection : Compares your custom slip against major sportsbooks like DraftKings, FanDuel , Caesars, and BetMGM to spot where the book's correlation pricing is off.ftnfantasy.com+1
• Real-Time Slip Building : Instantly displays cumulative win percentages, correlation adjustments, and expected value metrics as you add individual legs.ftnfantasy.com+2
• Odds & Vig Analysis : Alternatively, standalone calculators like the Odds Index SGP Calculator let you evaluate the market's implied probability versus the book's correlation tax.oddsindex.com+1

If you'd like, let me know:

• Which sport you are planning to bet on (NFL, NBA, etc.)
• Whether you want a breakdown of how correlation math works behind the scenes

I can help you fine-tune your strategy before building a slip.

Yes. If you specifically want a correlation-aware SGP builder, rather than a basic parlay calculator, these are the better options I found:

• betcalc365.com — probably the closest match. It explicitly models correlation between legs, estimates fair odds, and separates correlation effects from bookmaker margin.betcalc365
• vigkit.com — de-vigs individual legs, applies a correlation adjustment, and compares the resulting estimate with the sportsbook's SGP price.Vigkit
• sportsbettingoddscalculator.com — specifically designed to analyze SGP correlations and potential value.Sports Betting Odds Calculator
• bettitips.com — simpler, but lets you explicitly enter a correlation coefficient and see how it changes fair odds.Bettitips

What I'd use

If your goal is “give me a game, let me construct logical correlated legs, then tell me whether the sportsbook's SGP price is reasonable,” I'd start with BetCalc365 or Vigkit.

The important distinction is that simply multiplying the individual odds isn't sufficient for an SGP. For example, QB passing yards over + WR receiving yards over are positively correlated, so the joint probability isn't just the product of the two independent probabilities. Sportsbooks account for that when generating their SGP price.betcalc365+1

If you want, I can also act as the SGP-building tool for you: give me the sport/game and sportsbook (e.g. DraftKings, FanDuel, BetMGM), and I can help construct 2–4 correlated legs, explain the game script behind them, and compare the offered SGP price with an estimated fair price.

To build and analyze correlated same-game parlays (SGPs), you need tools that run simulations or leverage projections to find how one leg impacts the probability of another.

Here are the top options available for building, calculating, and evaluating SGP correlation:

• FTN Bets SGP Tool : Uses a simulation-based approach. By inputting your player props, game, and target sportsbook, the tool runs thousands of simulations based on advanced projections to account for real correlations between events, outputting a true win percentage and fair odds to compare against the books.youtube.com+1
• Odds Index SGP Calculator : A practical math-focused utility that breaks down your selected legs to show what the payout would be if the legs were independent versus what the sportsbook is actually offering. It helps expose the heavy juice and implied probability of your combined SGP.oddsindex.com+1
• PropsBot SGP Value Checker : Allows you to input multi-leg American odds and paste a sportsbook's quoted SGP price to see the value gap, how the book priced the correlation, and whether it’s a sharp bet or heavily over-juiced.propsbot.ai
• Platform Correlation Features (e.g., Stokastic / Action Network tools) : Many advanced projection systems feature correlated leg finders on the side of their prop screens that dynamically suggest high-grade pairing options (like matching a point guard's over on assists with a shooter's over on points).youtube.com+1

To help narrow down the best approach, let me know:

• Which sport are you primarily building parlays for (NFL, NBA, MLB)?
• Are you looking for a tool that automatically suggests correlated legs , or a calculator to test the math/value of legs you already picked?

Yes. If your goal is specifically building correlated same-game parlays rather than just calculating payout, these are the most relevant tools I found:

• Bettorly — probably the closest match. It analyzes how legs interact, shows synergy/correlation, conditional hit rates, flags conflicting legs, and can suggest replacements. It covers NFL, NBA, MLB and NCAAB.Bettorly+2
• EdgeSlip Correlation Matrix — specifically built around finding correlated SGP combinations, including teammate stacks and game-script relationships.EdgeSlip+1
• Bettor Results SGP Builder — useful if you want to backtest combinations and see how often the exact legs have hit together historically. It supports NBA, MLB, WNBA, NHL, NFL and NCAAF.Bettor Results+1
• BetCalc365 — better for understanding the math behind correlation, fair odds and expected value rather than generating picks.betcalc365+1

If you want, I can also be the tool

Give me something like:

NFL — Chiefs vs Bills — DraftKings — 3-leg SGP — want positive correlation and I can help structure the parlay around relationships such as QB passing yards + WR receiving yards, game total + player scoring, or other game-script combinations, then explain why the legs correlate.

Just keep in mind correlation doesn't guarantee a winning ticket, and sportsbooks already incorporate correlation into SGP pricing.sportsgameodds.com+1

Yes. If your goal is specifically to build correlated SGPs rather than just calculate payouts, these are the tools I’d look at:

• bettorresults.com — probably the best fit if you want to test whether legs actually hit together historically. It lets you combine player props and backtest the exact combination against game logs. It supports NBA, NFL, MLB, NHL, WNBA, and NCAAF.Bettor Results
• propsbot.ai — more geared toward AI-assisted construction, including a correlation indicator for SGP legs and edge/confidence scores.PropsBot
• vigkit.com — useful if you already have your legs and want to estimate fair odds after accounting for correlation, rather than naïvely multiplying the legs.Vigkit
• betcalc365.com — another correlation-aware calculator that compares modeled fair odds with the sportsbook's offered price.betcalc365

If you want me to actually build them for you

I can also act as the SGP builder here. Give me a game (e.g. Chiefs vs. Bills) and sportsbook/odds if you have them, and I can structure something like:

Game script: Chiefs lead → Bills throw more → Mahomes passing volume ↑ → Kelce/WR receiving opportunities ↑

Then identify:

• 2–4 positively correlated legs
• legs that are likely anti-correlated and should be avoided
• the strongest combination
• an aggressive vs. conservative version
• whether the sportsbook's SGP price appears reasonable relative to the underlying legs

One important caveat: sportsbooks already incorporate correlation into SGP pricing, so simply finding two highly correlated legs doesn't automatically mean you've found value.sportsgameodds.com+1

If you tell me the sport + specific game(s) you're targeting, I can help you build the SGPs.

To build and evaluate correlated same-game parlays (SGPs) , you need tools that either factor in team/player correlations via simulations or allow you to mathematically compare a sportsbook's offered odds against true correlated probabilities.

Here are the top tools and calculators designed to help you analyze or construct correlated same-game parlays:

• FTN Bets SGP Tool : A simulation-based builder that inputs player props, game data, and sportsbooks. “The tool allows users to select the over/under for each prop. By clicking 'calculate odds,' the tool provides the win percentage and the true odds for the parlay based on thousands of simulations” -- [FTN Bets ]. This directly accounts for internal correlations rather than treating legs as independent events.
• DarkHorse Odds SGP Correlation Calculator : Offers a specialized calculator with a Build Fair Price mode to construct fair prices using custom correlation assumptions, and a Check Book Price mode to see if a sportsbook's SGP price is positive or negative expected value (+EV).about.darkhorseodds.com
• Odds Index Same Game Parlay Calculator : A tool that lets you enter your SGP legs to view implied probabilities, the sportsbook's vig, and the difference between independent pricing and what the book is offering.oddsindex.com+1
• PropsBot AI Parlay Builder : Generates data-driven SGP and multi-leg combinations across major sports using confidence and edge scores derived from model probabilities.propsbot.ai

If you'd like, I can:

• Explain how to spot positive correlation between specific prop types (like QB passing yards and WR receptions)
• Show you how to calculate expected value (+EV) on an SGP
