What is a correlated parlay calculator?

A correlated parlay calculator computes the true joint probabilities of two or more betting outcomes that are statistically related. Unlike standard parlay math that assumes independence, this calculator accounts for correlation between legs — like a team winning AND covering the spread — to reveal edges that sportsbooks misprice in same-game parlays (SGPs).

How do I find edges in same-game parlays (SGPs)?

SGP edges come from sportsbooks pricing correlated outcomes as if they were independent. When two legs are positively correlated (like team ML and team total over), the "both hit" state is more likely than naive multiplication suggests. The calculator computes the true probability using bivariate Bernoulli correlation math and compares it to the book's SGP price to find mispricing.

What is parlay dutching?

Parlay dutching is a strategy where you bet on all possible outcome states of a multi-leg parlay across different sportsbooks. When books misprice correlated outcomes, you can cover all states and potentially lock in a profit regardless of the result. It combines correlation math with cross-book price shopping.

What are impossible worlds in betting?

Impossible worlds are outcome combinations that cannot logically happen. For example, a team losing AND covering the spread is impossible — if they cover, they must have won. Books still implicitly price these states in SGPs, creating systematic mispricing that the correlated parlay calculator detects.

How does correlation affect same-game parlays?

When parlay legs are correlated (like team ML and team total), the true joint probability differs from what naive multiplication suggests. A team winning AND scoring a lot are positively correlated — the "both happen" state is more likely than independent math implies, and the cross-states are less likely. This is why SGPs are often mispriced.

What is the correlation coefficient (rho) and how is it used?

Rho (ρ) measures how strongly two outcomes are related on a scale from -1 to +1. ρ = 0 means independent, ρ = 1 means perfectly correlated. For structural pairs like ML + Spread, ρ can be derived exactly from the odds. For other pairs, the calculator uses empirical estimates that you can adjust with a slider to test sensitivity.

Can I use profit boosts with correlated parlays?

Yes. The Boost Calculator tab lets you apply sportsbook profit boosts to near-miss opportunities. Since boosts are book-specific (a DraftKings boost only applies to DraftKings odds), the calculator automatically matches the boost to the correct book and recalculates whether the opportunity becomes profitable.
