Many 21st-century sportsbooks stopped letting you parlay two bets from the same game, like a point spread and the over together, because those bets could be correlated. If one happens, the other is more likely, so they didn't want you to get the full multiplier a parlay offers.

Then magically in 2019, FanDuel began letting bettors create parlays on the same game and started marketing it like crazy.

They called it the Same Game Parlay, it became wildly popular, and every major sportsbook launched its own version (some under different names, since FanDuel is trying to trademark same game parlay).

Our friends at SportsHandle reported that half of FanDuel's active users who bet the NFL in 2021 have also bet an SGP. And half of all new users place one in their first week. At BetRivers, 20% of all NFL bets have been SGPs.

Same game parlays can be as small as two bets, like Chiefs -4 and over 52.5 at something like +200. But most bettors are looking to tie a bunch of props together to create a lottery payout — sometimes north of 50-1, or even 250-1. At many books, you can add player props, game props, winning margins. The list feels endless. At bet365, you can even parlay a bunch of different same game parlays. SGP-inception.

You can bet SGPs in many sports but they're especially popular for primetime NFL and NBA games, because it gives you rooting interest in almost every play.

Sportsbooks have a tremendous advantage on parlays. New Jersey books have kept about 16% of all the money wagered on parlays compared to around 4.5% of straight bets; FanDuel in Illinois is north of 25%. The hold is probably even higher on SGPs.

SGPs are big moneymakers for sportsbooks, and bettors love to chase lottery payouts with small wagers on games they're watching anyway.

You're never really getting a fair price (you can use Scores and Odds SGP tool to see what the price should be). But if American bettors were concerned about what's fair, they'd probably find a new hobby altogether.

Here's an eclectic mix of 14 tips, strategies, warnings and ideas to think about when betting same game parlays, since you're going to do it anyway.

The Basics

1. What is a same game parlay?

It's a parlay with multiple bets from the same game. You must win every leg of the bet for it to cash.

Sportsbooks have productized same game parlays and put certain rules around them. You can't parlay everything, but the following are usually on the table:

  • Spreads
  • Totals
  • Every derivative of those (first half total, alternate spreads, etc.)
  • Player props
  • Game props (like first team to 10 points, will there be a fumble)

FanDuel has a separate tab for SGPs, and the bets will populate in your bet slip. You can only parlay bets from that tab, not everything offered on that game.

2. SGP Examples

Here's a simple SGP example.

You may like the Rams to win a lower-scoring game against the Cardinals. So you tie these three bets together for +486 payout.

same game parlay betslip-fanduel

Now let's keep the same theory about this game and add to it.

You like the Rams to win a low-scoring game but think Van Jefferson will be a key contributor for L.A., and two other players will go under their totals. It all still fits with your original theory/narrative, but now the payout is over 56-1.

The Math

3. Making sense of some math

TL;DR on the math: It's complex, the book gives itself an even bigger edge than normal, and they account for almost every related outcome. Click here to skip the math.

Sportsbooks get the complicated math and tech from specialized data providers, who are quite good at this. DraftKings uses Genius Sports for SGPs, and a few other books likely do too.

The books/providers are always going to be better at the math than you and me, and even if you can close the gap, they build in a ton of padding to protect themselves.

Any edge you think you're getting with correlated outcomes, they've accounted for and gutted the price accordingly.

The Chiefs covering -6.5 in the first half and -10 over the full game vs. the Raiders are correlated. If the first happens, the second becomes much more likely (NFL teams that cover the first half cover 74% of full games, via Bet Labs).

So the book isn't giving you the full prices on a two-bet parlay, which normally pays +260 (even though the true probability is +300).

Example 1: The Tax

There are three main ways a sportsbook cuts your payouts on SGPs:

  • The existing juice on each bet (like -110 on an NFL spread)
  • Correlations
  • This other random tax they throw on, just because

The first two make sense. The third is just rubbing it in.

So how do we figure out this random extra tax?

Let's use the Colts -2.5 (-112) and Jonathan Taylor rushing yards vs. the Patriots. If the Colts cover, it's more likely Taylor ran for more than 90.5 yards, so a parlay with his over pays less than one with the under.

Here's what each pays:

Now here's how we figure out the tax (stick with me).

I've created a scenario where I'm betting both those parlays and risking one total unit split between the two. If there was no tax, I'd win one unit no matter what if the Colts covered and lose one unit if they don't.

But there is a tax!

Because if the Colts cover, and either result happens with Taylor, I only return 1.78 units. If the Colts don't cover, we lose one unit.

Risking one unit and winning .78 units implies a -128 moneyline.

That means in this parlay, FanDuel has turned Colts -2.5 from -112 to -128. That's a break-even rate of 56.14% compared to 52.83%.

That's 3.31% in extra vig for the book, on top of the 2.83% juice they're already charging you.

Highway robbery, and FanDuel often has the best pricing for SGPs!

At PointsBet, it's similar — on a Chiefs and Justin Herbert pass attempts parlay, they've turned Chiefs -3 from -110 to almost -129.

Example 2: Separating Correlation

We now know the sportsbook is secretly giving itself an extra at least a 3%+ edge for extra cushion on every parlay, and likely higher in a lot of cases.

I also wanted to give some insight into how the book separates correlation among bets in a parlay, though there's so much more math out of my scope that goes into how they determine the amount of correlation between each bet.

Take this example:

  • Chiefs -10
  • Chiefs -6.5 first half
  • Over 47.5 full game

A three-bet parlay with each at -110 normally pays +595. This one pays +357.

We have two bets that are highly correlated — Chiefs and Chiefs 1H — plus a third that's correlated to both, but only a little bit (favorites cover slightly more often when the game goes over).

A +357 parlay compared to a +595 parlay is a 7.5% difference in break-even rate.

But how does it break down between the three bets? The chart below shows you.

The correlation that's costing you is the Chiefs full game and first half spreads. Makes sense. They're more correlated.

FanDuel offered +143 for Chiefs -10 and -6.5 1H, compared to +260 for a normal two-team parlay — a 13.37% probability cut.

I tried to figure out some of the correlation math, and even turned to some of the smartest folks at Action to help, with little luck.

From our Data Engineer, Billy Doyle: "There's really no way to know exactly what they're doing without a lot of data from books."

This is all to say we'll never beat the books on correlation — if you think you're pulling a fast one on 'em by parlaying Justin Herbert 3+ touchdowns with Chiefs -3.5, they're accounting for it.

The books have better math and build in huge cushion to protect themselves, even if some math is exploitable.

And if correlation for a prop can't be easily accounted for, they just don't offer it.

4. Some books will gouge you for non-correlated bets, too

The books should adjust your prices for correlated outcomes on parlays. That's what makes SGPs a fun, lottery-style game.

But some books will shave the price even for two completely unrelated events. Not every bet influences another in a single game, but that's how it's treated, just because they know they can get away with it.

Example 1: Independent Events

Titans RB D'Onta Foreman (+150) and Jaguars WR Laquon Treadwell (+400) each scoring a touchdown in the same game aren't really correlated. They're independent events (and perhaps even a tiny bit negatively correlated, since there are only so many TDs to go around).

If you added other bets to that parlay, like a moneyline or total, then a correlation begins to form.

So why shouldn't you get the full price for that simple two-bet parlay? DraftKings paid out +1000 for that Foreman-Treadwell parlay, which should have been +1150 given the +400 and +150 prices.

  • DK Parlay Payout: +1000
  • Normal Payout: +1150
  • Probability Difference: 1.09%

Going from +1150 to +1000 doesn't seem like much, but it's more than a 1% difference.

DK is taking an extra 1% for no reason, on top of the normal juice, on top of the parlay tax. Highway robbery.

Example 2: Same Bet at the Same Book, Worse Price

Sometimes sportsbooks will offer you better prices on certain pre-made parlays than on SGPs.

Wednesday night, John Collins to score 15+ points and Hawks moneyline paid -115 in an SGP, but it paid +100 under FanDuel's "performance doubles" for the exact same thing!

hawks same game parlay example

5. Odds increases are not created equal

Sportsbooks don't want you to think about odds in probabilities. They just want your eyes to light up when you add one more bet to your 10-pick, same game parlay to take it from 150-1 to 500-1.

The implied probability of hitting a 150-1 parlay is .66%. Hitting a 500-1 parlay has a .20% chance. It was already incredibly unlikely to hit.

The big changes are in lower numbers.

The drop in probability from +200 to +450 is 15.15%.

That's the same drop in probability from +450 to +3200.

You may think going from +200 to +450 isn't a big deal when it comes to the chances of hitting your parlay. But it's an incredibly big difference.

Try to contextualize odds changes by percentages, not by American odds.

Best & Worst Sportsbooks for SGPs

6. The best books to bet SGPs

Most of the major American sportsbooks are starting to offer same game parlays because 1) bettors love them and 2) they're advantageous for the books. Win-win, I guess.

Our Favorites

  1. FanDuel: Best combination of available bets, UX and pricing.
  2. PointsBet: Good SGPs with lots of betting options, and other points betting products offer similar entertainment.
  3. BetRivers/SugarHouse: Poor UX, but bettors can combine multiple bets from multiple games.

1. FanDuel

FanDuel was the first to market with SGPs and has maintained its lead. The pricing is transparent, unlike some competitors, and they have plenty of props to bet.

FanDuel doesn't have quite as many bet types as DraftKings, but they have a good menu overall.

2. PointsBet

PointsBet has other lottery-type betting modes and a pretty good SGP product.

PB has most of the same betting options in SGPs as DraftKings, with better pricing.

3. BetRivers/SugarHouse

The pricing from the Rush Street books seems to have gotten worse in the last few weeks, but they do allow you to combine multiple bets from multiple games, which can be a fun option — think Jets moneyline and over 43 vs. the Dolphins, parlayed with Giants moneyline and Mike Glennon over 2.5 touchdowns vs. the Cowboys (kidding, please don't bet this).

7. Avoid DraftKings, other books that hide odds

Try to avoid SGPs at books that don't show you the odds on every prop. They're trying to make you forget how bad the pricing is.

If I want to bet the Chiefs alternate spread of -13.5 and Chiefs team total over 35.5 points, they don't show you the individual odds for each — only the final parlay price. It's helpful to see the odds for each to better contextualize how likely these things are to happen.

draftkings single game parlay
So avoid DraftKings for SGPs. The UX is great, but the betting product isn't:

  • DK doesn't show you the odds on each bet…
  • …and gives you bad prices
  • But they do have a lot of betting options

Their product is designed to make you not think about how bad of a shake you're getting.

That same Chiefs parlay from above pays much worse at DK than at FanDuel.

If DK has the best price on a parlay you've already settled on, bet it. But I wouldn't start your SGPs there. PointsBet, if available in your state, offers a similar product product with slightly better pricing on the same bets.

Here's another example — for Cardinals-Rams on MNF, you were getting the same price at PointsBet (+1800) for this three-bet parlay as the four-bet version at DraftKings that added Cooper Kupp 100+ receiving yards.

DraftKings also requires you to add the same-game parlay to your bet slip, but you can't edit it once it's been added — you either need to bet it or start over.

Strategies & Tips

Again, the correlation is all baked in. Anything I reference here, the book has accounted for and then some. We're trying to create outlier situations to hopefully hit one SGP that pays for all the other losing tickets.

8. Finding usage changes before they change

Sports statistics in a single game are just a giant pie chart based on the distribution of opportunities.

Sportsbook models aim to simulate a game, and they change dynamically if players are ruled out — so if Steph Curry is out for the Warriors, the spread, total and every prop will change, usually all at once, based on how they expect the game to go without Curry. Or they'll take everything off the board until they have time to adjust.

But let's talk about usage for a second. If Curry doesn't play, his 20 field goal attempts per game will go to other players. They don't just disappear.

Using our NBA On/Off tool at FantasyLabs, we can see that Jordan Poole accounts for 30% of Golden State's points with Curry off the floor and just 16% with Curry on, so he's due for a big bump if Curry ever sits.

FanDuel listed Poole at +385 to score 25+ points on Monday night against the Pacers. He scores 25.9 points per 36 minutes with Curry off the floor, so it's not inconceivable he'd be in for a huge night without Steph.

If Curry didn't play, all Poole props would change significantly because Curry's vacant usage will be distributed amongst the rest of the Warriors in a sportsbook's models, and a big chunk would go to Poole. He may drop to +150 to score 25+ points, instead of +385 with Curry in.

Of course, sportsbooks know this and do a few things to combat it.

  • They don't list every player. With De'Andre Ayton out Monday for the Suns, they didn't have Javale McGee, the main beneficiary of that leftover usage, listed in any props.
  • They play it safe with injuries and don't list players who will have big swings in usage if another player is ruled out. About 24 hours before TNF, sportsbooks didn't have Chargers receiving props listed because WR Keenan Allen was in COVID protocols.
  • They don't add new players when one player is ruled out.
  • They're often just as fast reacting to change these prop prices, but not always. You can catch them napping on some derivatives.

Try to look for situations with questionable players where that player is still listed as an option to bet before being ruled out.

It's the same way in football. A sportsbook's models will give Vikings WR K.J. Osborn a bump across the board if Adam Theilen doesn't play, so you're not getting any edge there.

The key is to find outlier situations that the normal range of outcomes doesn't account for.

Per SharpFootballStats, the Raiders ran 11 personnel sets (3 WR, 1 TE, 1 RB) on just 55% of their plays from Weeks 1-12. Then without TE Darren Waller in Weeks 13-14, they ran 88% of plays from 11 personnel. The books won't account for a drastic shift like that.

A book's models will also account for Hunter Renfrow's increased usage without Waller, but in hindsight they did not account for this outlier situation where so many of Waller's snaps and targets went to Renfrow, who is averaging almost 10 catches and 93 yards per game with Waller out.

Waller's absence also led to increased usage for receivers down the depth chart, including Zay Jones and DeSean Jackson.

9. Form a narrative but add a contrarian element

We form beliefs about a game and then bet them. This is not exclusive to SGPs. This is sports betting for most people.

One good way to juice up your parlays is to use a prop that fits the opposite narrative of everything else you've bet.

In this case, we'll get negative correlation, which increases your payouts.

Betting Matthew Stafford over 283.5 passing yards and Van Jefferson over 50.5 receiving yards paid +192 on Monday. The same Jefferson over and Stafford under paid +362 — almost a 13% difference in probability.

So what's the strategy here? Create parlays with correlated bets, then include 1-2 that don't fit that narrative but will give you some upside and still fall within a reasonable range of outcomes.

You need a few things to happen in the parlay below.

  • The Chiefs to win, and Tyreek Hill to score
  • The Chargers to be competitive and Justin Herbert to put up garbage time stats (he's thrown for 300 yards in two of LA's four losses).

Check out how the odds change when you add the over — from +971 to +1365. That's because a successful Herbert night is correlated with the over.

Throw in an alternate under of 58.5 and it moves to +2197. That's because it's negatively correlated with a good game from Herbert.

But the game going under 58.5 is in a reasonable range of outcomes, even if Herbert plays well. Just 32% of NFL games in the last three years with closing totals of 50-53 had more than 58 points.

You're counting on the Chiefs to win something like 28-27 and Herbert to keep the Chargers competitive. It's still a longshot at 22-1, but if I told you that narrative played out, you wouldn't be shocked.

» Return to table of contents «

10. Look for games with asymmetric upside (or downside, more often)

You want to identify situations where if the bottom falls out, it will really fall out. Or if the lid gets blown off, it really gets blown off.

In hindsight, Bills-Patriots in the snow and wind on Monday Night Football had that downside.

QB Mac Jones and every Patriots receiver finished under their props because the Pats threw the ball three times. The correlation for all those unders was baked in, of course, but a book's pricing models can't account for extreme outlier situations.

The all unders parlay turns $50 into $20.7K 😳

Luka Doncic struggled on the second leg of back-to-backs last season and was in a brutal travel spot, so this was a great way to bank on him having an outlier poor performance (again, in hindsight).

Joe bet the under on Luka's "Points x Rebounds x Assists", which went way under the posted total of 2768 because he finished with just 15 points, 7 boards and 9 assists (1579 = 945).

11. Think about the distribution of stats in a single game

Most results in football games fall into a reasonable range of outcomes. Based on teams, the spread and the over/under, we can estimate how many touchdowns and yards there will be.

But it's so difficult to try to predict a team's entire stat profile.

Betting three players from the same team to score anytime touchdowns is an impossible proposition, even if the game is higher scoring than normal. NFL teams only average about 2.64 TDs per game, so you'd have to get all or most of the touchdowns correct.

It's the same way with yardage. There are only so many yards to go around, so betting three players to have 70+ receiving yards is so difficult.

Instead, mix and match yardage props, touchdowns and other game props.

Let's take a look at a well-distributed SGP that did hit big.

Oh my goodness I just hit the SGP of my life. On Thanksgiving no less. Going to put a chunk of this towards good causes, but first a little celebration!

— Cal Spears (@CalSpears) November 26, 2021

Based on the over/under (51) and each team's season averages, we can guess there would be about six touchdowns scored and 800 total yards in that Cowboys-Raiders game.

So with Cal's six props, he only needed to correctly guess about 20% of the total yards and 33% of the available touchdowns. Still a very difficult thing to do, but it's better than trying to guess every single yard or TD.

He needed a few things to happen for this narrative to play out:

  • The Cowboys to move the ball at their normal rate (~415 yards per game)
  • The game to stay competitive, which would likely help running backs add a few catches late
  • Michael Gallup to shine with Amari Cooper/CeeDee Lamb out
  • DeSean Jackson to hit one big play

That doesn't sound so impossible, especially for 265-1!

It becomes more difficult if you need Gallup to hit 100+ yards, Zeke to run for 65+ yards, and Dalton Schultz to hit 55+ yards. Now you're trying to predict more than half the Cowboys' total yards.

We fool ourselves into thinking that if an offense goes off, everyone will go off. But consider that Seahawks WRs Tyler Lockett and D.K. Metcalf have only both had 100+ receiving yards in the same game twice in their careers.

Even in a big offensive game, there's only so much to go around. Don't add too many big yardage totals from the same team or try to predict 3-4 touchdowns from the same team.

12. Chase opportunities, not results

This applies to most things in sports betting. Worry about opportunities, not the previous outcomes.

Anytime touchdown scorers are especially popular in SGPs. Look at who will be on the field, and who gets touches/targets. There's a lot of randomness in touchdowns week to week.

It's the same way for basketball — the best indicators of success in a single game are simply how often a player will be on the floor and touching the ball.

13. Dig Deep for Inefficiencies

If the books had to do it all over again, they wouldn't have allowed the parlay below. Jakeem Grant and Chicago D/ST scoring a touchdown were highly correlated, because Grant returns punts.

Even if they do allow this parlay again, it should have paid closer to 30-1, not 240-1.


(via @kiiLkenny | @FDSportsbook)

— Action Network (@ActionNetworkHQ) December 13, 2021

No one is going to give these "errors" away, because they don't want the books to catch on. I don't have any for you, and I wouldn't tell you if I did.

But dig deep for inefficiencies in the book's product, and hold onto those edges for as long as you can.

Like I said before, if a book can't account for who returns punts, they'll just stop offering D/ST units as anytime touchdown scorers, like DraftKings does.

14. Remember that everything is designed for overs and "yes" props, and there's a reason for it

It's human nature to root for things to happen. No one wants nothing to happen in the games they bet, especially a standalone, national TV games where SGPs are so popular. You're also always in it with an over — even if D.K. Metcalf doesn't have a single catch with two minutes left, he can hit over 64.5 yards in one play.

The SGP products have all been designed with this in mind. They want you to bet overs and yes props.

There are two things to consider:

1. They don't let you bet unders and no's

Cooper Kupp was -135 to score a touchdown vs. the Cardinals. Why can't you bet him +115 to not score?

Kupp had only scored in 58% of his games this year, right in line with that -135 price. Last year, he scored in just three of 15 games.

You can bet Patrick Mahomes alternate over 200.5 passing yards at -1600 — why can't you bet an alternate under 200 yards at +800?

Why don't they offer the other sides? They don't want you to think about the pricing, and how bad it is. They want to pigeon hole you into creating SGPs around single narratives, like the game being high scoring and lots of players scoring touchdowns, and then gouge the price.

2. They give you worse numbers on overs and favorites

For Chiefs-Chargers on Thursday Night Football, DraftKings' regular markets had Chiefs -3 and the total at 52.

Flip to Same-Game Parlay mode, and the Chiefs are -3.5 and the over is 52.5. They know you're going to bet favorites and overs, and will shade lines towards that (and not give you a better price on them).

3. So consider some unders, please

Ever hold your breath every time a QB throws a pass, hoping it doesn't go to the guy whose receiving yards under you bet? Yeah, it's pretty awful.

But props go under more often than they go over against the closing line.

Look at this great thread from PFF's Ben Brown — in most situations, unders hit more often than overs. Even when a team is the favorite, all player props go under 52% of the time. When they're an underdog, unders hit 52.78%.

.@VegasRefund wanted a view on how the spread could influence props…

15. Final Thoughts

The house has an even bigger edge than normal here. You'll never get fair prices based on the actual probability.

But you're going to bet SGPs anyway. If people were turned off by getting an unfair shake, they wouldn't bet on sports at all.

Your biggest asset is you just need one outlier situation that the books couldn't account for in a normal distribution of outcomes.

Hopefully some of these ideas can help you create one.
