A same game parlay (SGP) is a parlay where every leg comes from a single game. Instead of combining bets across multiple contests, you pick two or more outcomes from the same match – the spread, total, moneyline, player props – and package them into one ticket.

All legs must win for the bet to pay. One loss and the whole ticket loses.

SGP vs regular parlay

The core mechanic is identical: multiple legs, all must hit. The difference is scope.

A regular parlay betting three -110 legs from three different games gives you approximately +595. The same three outcomes from one game as an SGP might price at +400 – lower, because the outcomes can move together.

Correlated vs uncorrelated legs

This is the single most important concept to understand about SGPs.

Correlated legs are outcomes that tend to happen together. If one comes in, the other is more likely to as well.

Example: Patrick Mahomes over 300 passing yards + Tyreek Hill over 80 receiving yards. If Mahomes throws for 300 yards, Hill almost certainly had a big day too. The outcomes are linked.

Sportsbooks reduce the payout on correlated SGPs. The correlation means the bet is easier to win than the individual odds suggest – so they adjust. Some sportsbook won’t allow certain correlated combinations at all.

Uncorrelated legs are outcomes that don’t directly influence each other.

Example: LeBron James to score the first basket + game total to go over 220.5. Whether LeBron scores first has almost nothing to do with the final combined score. These are independent events within the same game.

Uncorrelated SGPs pay closer to standard parlay odds, because the sportsbook gets less of an edge from the combination.

The counterintuitive result: correlated legs often pay less than uncorrelated ones, even though they seem „safer” to a bettor who has a coherent game script in mind.

What you can include in an SGP

Most sportsbooks allow these markets as SGP legs:

• Moneyline (which team wins)
• Point spread (margin of victory)
• Total (over/under)
• Player props (points, yards, touchdowns, rebounds, goals, assists)
• Team props (first team to score, first quarter winner)
• Live in-game markets (where available)

The easiest way to check: look for the SGP indicator next to markets in your sportsbook’s game view. Anything tagged as SGP-eligible can be added.

Maximum legs vary by book. Hard Rock Bet allows up to 20 legs on one SGP.

How odds are calculated

SGP odds are not simply multiplied together like a regular parlay. Sportsbooks use proprietary algorithms that adjust for correlation.

This creates a situation where two SGPs with the same individual leg odds can pay differently depending on which specific legs are combined. LegalSportsReport tested this: two different -110/-110 two-leg SGPs on the same game produced +235 and +247 respectively – nearly identical legs, different payouts.

For context, a standard two-leg parlay at -110/-110 would pay approximately +260. Both SGP versions came in lower – the house is taking more margin.

This is why SGPs have a higher house edge than standard parlays. The sportsbook captures extra margin through the odds adjustment for correlation. You see attractive payout numbers, but the implied probability is worse than if you bet each leg individually.

What happens when a leg pushes or voids

If one leg of your SGP results in a push (tie) or is voided (player scratched, market cancelled):

• The voided/pushed leg is removed from the ticket
• The remaining legs are recalculated with new combined odds
• The SGP continues with fewer legs
• If the void leaves only one leg standing, most books treat it as a straight bet

This is better than losing the whole ticket, but the payout drops substantially when a key leg disappears.

Different names across sportsbooks

SGP is the standard abbreviation, but different books brand it differently:

• FanDuel – Same Game Parlay (SGP) – coined the term and was first to market
• DraftKings – Same Game Parlay (SGP), also offers „SGP+” which chains multiple SGPs together
• BetMGM – One Game Parlay (OGP)
• bet365 – Bet Builder
• Caesars – Same Game Parlay

FanDuel pioneered the format. The mechanics are identical across all platforms – only the branding differs.

SGP+ and SGP Max

Several sportsbooks now allow you to build a „parlay of parlays” – combining multiple SGPs from different games into one ticket.

DraftKings SGP+ lets you take an SGP from Game A and an SGP from Game B and link them. If both SGPs cash, you win the combined ticket.

Hard Rock Bet SGP Max works similarly.

This adds another layer of variance on top of an already high-variance bet type. The payouts are enormous. The probability of winning is very small.

Why sportsbooks love SGPs

Lost in the hype: SGPs are extremely profitable for sportsbooks.

Traditional parlays already have a higher house edge than straight bets. SGPs compound this in two ways:

1. Higher margin on odds – the correlation adjustment builds in more edge for the book
2. Harder to price correctly – bettors can’t easily calculate the true odds of a correlated SGP, making it harder to spot bad prices
3. Engaging product – one game, multiple things to watch, creates entertainment that keeps bettors returning

The viral social media clips of someone winning a 10-leg SGP at +15000 exist because the hits are spectacular. The losses – far more frequent – don’t get posted.

Example SGP

NFL game: Chiefs vs. Chargers

If this were a standard parlay, these three legs would pay approximately +380-400. As an SGP (because Mahomes TDs and Kelce yards are correlated), the payout might be +280-320. The sportsbook takes more margin for the correlated combination.

FAQs

Who invented the same game parlay?
FanDuel developed and launched the SGP product first. Other major sportsbooks followed once the format proved popular. The format was initially resisted by books because of the risk of correlated outcomes – advances in real-time odds modeling made it viable.

Why does my SGP pay less than a regular parlay with the same legs?
Because the sportsbook adjusts for correlation. When the outcomes of your legs are linked (which is common in single-game bets), the true probability of winning is higher than the individual odds suggest. The book lowers the payout to compensate.

What’s the max number of legs on an SGP?
It varies by sportsbook. Hard Rock Bet allows up to 20. Most major books allow somewhere between 10 and 20 legs.

Can I cash out an SGP early?
Some sportsbooks offer early cash-out on SGPs, but it’s not guaranteed. Availability depends on the book and the specific game situation.

Is an SGP a good bet?
It has a higher house edge than straight bets and standard parlays. The payouts are attractive, but the odds are worse than they appear. If you’re going to bet SGPs, keep legs small (2-4 legs) and look for legs that tell a coherent game story rather than throwing in maximum legs for the biggest number.
