hits together 3.52× more than independent odds imply
🗑️ The Dumpster
What most people bet: legs that historically pull in opposite directions.
chemistry −0.37 · when one hits, the others miss
Why parlays feel rigged (they're just badly built)
Books love parlays because most people combine legs at random. Random legs means paying the parlay tax with zero story bonus — and worse, legs that actively cancel each other out. SGP King fixes the construction, honestly.

Team chemistry
Green links between props that win together, red between props that fight. Tap players on the pitch and build your squad's story.
📊
Real joint hit rates
Not a model's opinion — actual counts. "These 4 legs landed together in 9 of 41 games." Sample sizes always shown.
🩹
Injury-aware
Star running back ruled out? Tap ✕ and every stat recalculates using only the games he actually missed.
🔄
Unders are chemistry too
Negative correlation isn't a warning — it's an Under waiting to happen. One tap flips a fighting leg into a coherent story.
📈
The sweat profile
See how often a parlay near-misses vs. dies by halftime. Coherent parlays stay alive longer — that's the entertainment you're paying for.

FAQ
Does this make parlays profitable?
No, and anyone who tells you otherwise is selling something. All parlays carry a price premium. SGP King makes your parlay coherent — legs that rise and fall together — so you stop paying for combinations that mathematically fight each other, and your entertainment budget buys longer sweats and better-constructed bets.
How does the engine work?
The Correl8 engine is built on complete game-level results for every NFL team across five full seasons. Recent seasons count exponentially more than older ones, and games where a player left injured are excluded so partial outings don't fake relationships. Every number on screen shows its sample size — and when a sample is too small to be meaningful, we say so instead of showing a number.
What's a "correlated parlay"?
Legs whose outcomes move together. If Mahomes throws for 300, Kelce probably caught a chunk of it — those legs are correlated. Books price same-game parlays knowing this; casual bettors combine legs blindly. SGP King shows you the correlation before you bet.
