What Makes an NFL Same-Game Parlay Different
A standard parlay pulls legs from separate games. A same-game parlay — often called an SGP — pulls every leg from one NFL contest, which means the outcomes can naturally affect each other. A running back racking up rushing yards, for example, correlates directly with the team covering a spread. Sportsbooks price this correlation into the odds, so the multiplier is lower
than stacking random legs, but the logic behind each combination is sharper. On spinszy, you build an SGP by selecting a game, adding your first leg, then layering in props and totals from that same matchup. Availability depends on your state and eligible markets.
