What a Same-Game Parlay Actually Does
A standard parlay combines bets from different games. A same-game parlay keeps every leg inside one NFL matchup — say, Patrick Mahomes over 275 passing yards, the Chiefs -3.5, and the game total over 49.5. Because the outcomes inside a single game are correlated, oddsmakers apply correlation adjustments when pricing the combined line. That pricing math is different from a cross-game parlay.
Our SGP builder shows you the running odds as you add each leg, so you see exactly how the multiplier shifts before you lock anything in. Legs that conflict outright — like backing the same player to score a touchdown and to be held scoreless — get flagged before you submit.
