Same Game Parlay (SGP)

What an SGP Is

A Same Game Parlay (SGP) is a parlay where every leg comes from the same game. Want to bet that the Celtics will win and Jayson Tatum will score over 28 points and the game total will go over 230? That's an SGP. Traditional parlays block correlated outcomes (since a Celtics blowout makes both the win and the over more likely), but SGPs are priced specifically to account for that correlation; at lower multipliers than the math would otherwise produce.

Vermont Example; Celtics SGP

A 3-leg Celtics-Knicks SGP:

• Celtics moneyline –180 (1.56)
• Tatum over 27.5 points (–115, 1.87)
• Game total over 222.5 (–110, 1.91)

If these were independent legs, the multiplier would be 1.56 × 1.87 × 1.91 = 5.57. Because the outcomes are correlated (a Celtics win typically means Tatum scored well and the total went over), the operator might price the SGP at 4.20 instead. You give up roughly 25% of the "free parlay" multiplier in exchange for being allowed to stack correlated bets.

Why SGPs Are Popular (and Lucrative for Books)

SGPs deliver three things bettors love:

• Easy storytelling ("Celtics blow out the Knicks behind 35 from Tatum")
• Bigger payouts than singles
• One game to follow rather than a slate

Operators love them because the implicit house edge on a 4-leg SGP often runs 15–25%; much higher than a 4-leg cross-game parlay because the correlation-adjusted prices favor the book. FanDuel popularized the format starting in 2019 and still has the most polished SGP product in the US.

SGP+; Combining Multiple Games

Most VT operators also offer "SGP+" or "Multi-Game SGP"; combining SGPs from multiple games into one mega-parlay. The cumulative house edge compounds further. Fun to win, devastating when you're 4-out-of-5 and the 5th leg loses.

Vermont-Specific Restriction

Per Vermont law (H.127), SGPs cannot include player-prop legs on in-state college teams; meaning no SGPs featuring UVM Catamounts player props. Game-level SGPs (spread + total + 1H spread) on UVM games are allowed. See the college betting page for full restriction details.

Operator Notes for Vermont

FanDuel has the broadest SGP catalog and the most aggressive pricing. DraftKings is a close second with strong NFL and NBA SGP depth. Fanatics offers SGPs but with fewer eligible markets and slightly worse multipliers.

Strategy Notes

• Look for under-correlated legs the book might be mispricing
• Avoid 6+ leg SGPs; house edge is brutal
• Track which operator pays best on your typical SGP profile
• Use SGPs sparingly relative to bankroll; they're high-variance entertainment, not consistent profit
