Master Your +EV Parlays with GamedayMath

February 12, 2026 by Dana

If you have ever felt like building a parlay was more of a "vibes-based" exercise than a mathematical one, you are not alone. With the right data, parlays can become a powerhouse tool for your ROI.

To supplement our latest tutorial video, this guide breaks down the brand-new Parlay Generator, an exclusive feature for Plus members designed to optimize your betting hierarchy and maximize value.

Why Use the Parlay Generator?
In the past, GamedayMath users could build parlays manually by selecting individual plays from the Picks Page. While effective, this required you to find the value yourself. The new Parlay Generator automates this by using the proprietary GamedayMath logic to instantly identify and combine the best top-down EV bets at any given moment.

Key Features Include:
Customization:
Filter by specific retail sportsbooks (FanDuel, DraftKings, etc.), dates, and sports.
Scalability: Choose the number of legs for your parlay and watch the system generate an optimized BetScore.
Flexibility: It is particularly useful for users who have been "limited" on certain books like BetMGM or Fanatics, providing a way to stay active with mathematically sound plays.

The Math Behind the "Score"
The generator doesn't just throw random legs together; it hunts for BetScores that indicate a statistical advantage. For example, while a manual parlay might result in a low EV play (0.5% ROI), letting the generator’s logic take over can produce parlays with scores of 79 or higher, significantly increasing your expected return.

Pro Strategy: Navigating Profit Boosts and Peer-to-Peer Sites
One of the most powerful ways to use the Parlay Generator is in conjunction with sportsbook promotions.

  1. Peer-to-Peer (P2P) Sites: The generator does not produce "actionable" odds for P2P sites like Novig directly because those platforms use proprietary pricing. However, you can use the generator to find high-value legs and then apply profit boosts (like a 25% basketball boost) on the P2P site to turn a standard parlay into a high-EV winner.
  2. Retail Book Boosts: Sites like DraftKings frequently offer 20% "any sport" profit boosts. By generating an optimized parlay first and then applying the boost, you can achieve an expected ROI of 6% or more.

Important Disclaimers
Not for SGPs: This tool is designed for round-robin independent events where odds can be combined. It does not currently support Same Game Parlays (SGP).

Plus Tier Exclusive: This level of optimization is only available to our Plus Tier subscribers.

Track Your Way to Professional Growth
Once you’ve generated and placed your bet, you can instantly add it to the Bet Tracker. This allows you to monitor your "Expected Edge" versus your actual profit, ensuring you are playing the long game and treating your betting like the professional endeavor it is.

Put the GamedayMath Parlay Generator to work for your bankroll.
