We get asked about SGPs a lot at GoBet so here is a quick rundown based on how we actually use them ourselves.
What it is
A same game parlay is where you combine multiple bets from one game into a single ticket.
So instead of betting Chiefs to win as one bet and Kelce over 5.5 receptions as a separate bet you put them together and the odds multiply.
Both legs have to win for the bet to pay out. You can stack as many legs as you want but the more you add the harder it is to hit.
Sportsbooks only started offering these a few years ago. Before that you could not parlay picks from the same game because the outcomes are connected to each other.
The books worked out how to adjust the pricing to account for that and now every single app pushes SGPs harder than any other product they have.
Why the books love them
Because they make more money on them than almost anything else.
The house edge on a five or six leg SGP is significantly higher than it is on a straight spread bet.
Those 10 leg SGP screenshots you see on social media paying +50000 look great but there is a reason the book was happy to offer that price.
How we actually bet them
We keep ours short. Two legs, sometimes three. We start with a game outcome we feel strongly about and then add one player prop that makes sense if our read on the game is right. Bills to win and Josh Allen over 1.5 touchdown passes. That kind of thing.
We went through a phase of building four and five leg SGPs because the payouts looked too good to pass up.
We hit the game outcome and the first prop almost every time but the third or fourth leg kept killing us.
Went back to two leg SGPs after that and have been much happier with the results.
