What is a Same Game Parlay (or SGP)?
The term refers to a type of single bet which consolidates numerous results of the game into one betting slip. For the bet to win, each leg has to win for the bet to pay out — one pick being wrong will lose the entire stake.
How Same Game Parlay Differs from a Traditional Parlay
Standard parlays factor in bets across numerous games or sports. However, single game parlay puts all its bets within one single event, such as identifying the winning team, total points, and player props from the same event or game.
Where It Came From
FanDuel is responsible for creating this innovative format that is currently acting as a yardstick for the entire industry. The game’s format is the universally recognized term used by other betting brands like DraftKings, bet365, BetMGM, and Caesars.
The name varies depending on the operator, with either “One Game Parlay” or “Single Game Parlay” used. However, the concept remains the same.
Why It Was Prohibited Before
Until now, one game parlays were banned because of correlation in that the outcomes within the same game are connected, making certain combinations exploitable.
Because of the development of pricing technologies, sportsbooks are able to take into account the correlation and make these games possible and available.
How a Same Game Parlay Works in Practice
The Step-by-Step Process:
- Pick a game: you may select any eligible sport and game
- Choose more than one market: this could be point spread, total, player props, or game props
- Construct a parlay: include legs in the bet slip using the one game parlay builder
- Sportsbook computes combined odds: this takes into account the correlation among the legs
- All legs must come through: a loss in any leg nulls the entire ticket
Complicated, right? Let’s take a look at an example:
In an Superbowl match of the Eagles against the Chiefs, the player places three bets:
- Leg 1: Chiefs winning the match.
- Leg 2: Total points in the match exceed.
- Leg 3: Patrick Mahomes has 280 yards of passing.
All of them should hit the winning criteria. In case the player throws for just about 260 yards in the match, the overall same game parlay bet will lose regardless of the success of the two preceding legs.
The Correlation Adjustment
Unlike conventional parlays where odds increase individually, same sport parlay odds are adjusted by the bookmaker according to the connection that exists among different legs of the parlay.
If Mahomes throws for 300 or more yards, it becomes more likely that both the Chiefs will win the game and the over is hit. The sportsbook recognises this fact and shortens the combined odds accordingly. Realising this is key when assessing parlays in betting and is exactly what most players fail to comprehend when comparing their anticipated returns with the odds on the ticket.
Differentiating Correlated and Uncorrelated SGPs
Comprehending correlation is the factor that distinguishes a knowledgeable one game parlays from one that has been incorrectly priced.
Correlated Same Game Parlay
Events that are connected directly to one another with regard to the same game.
Let’s look at an example to understand this better:
The quarterback passes 350 or more yards, and the wide receiver gets more than 90 receiving yards. It is highly likely that if the quarterback is throwing that much, the receiver will also achieve the target, and sportsbooks, knowing this, will shorten the odds or ban the combination.
Uncorrelated SGPs
As the name implies, these are results that do not influence each other directly.
For example, the game total goes over, and a kicker makes 2-plus field goals. The outcome will not be strongly correlated, and odds will be very similar to standard parlay math.
Why It Matters?
Learning these two main sports betting terms when discussing single game parlays is important because:
- Heavily correlated same sport parlay yield much lower payouts compared to players’ expectations
- Some combinations of bets are not allowed by the sportsbooks
- Certain same game parlays may be available for +650 on one site and +850 on another site — different operators can manage correlation differently
Controlling correlation limits is an important function for operators in their margin safety process. An incorrectly set correlation limit, regardless of whether it is too strict or too lenient, has an effect on the extent of product competitiveness and liability risk.
The Next Evolution: SGP+
SGP+ (also called SGPx) is an advanced version of single game parlay that combines parlays from different games into a single betting ticket.
How It Operates:
- You create your one game parlay for one of the games — for example, the Chiefs and the Eagles
- Then you create a second one from another match — say, the Lakers against the Celtics
- Finally, you merge the two together as single game parlay plus
This correlation change happens within each same parlay game, but since the legs at several games are independent from each other, their total probability can therefore be computed closer to conventional same game parlay calculations.
Who Provides It?
Customers can find the SGP+ offered on sites such as FanDuel, DraftKings, Hard Rock, and bet365. Although the mechanism remains consistent, the name varies based on who the operator is.
Why Operators Added It?
- Expands same sport parlay ticket creation to cover not just individual games
- Users have an option to generate tickets from stories during sunday slate
- More quantity in terms of handling in each ticket than in single game parlays
- Another promotional opportunity is that SGP+ insurance and enhancements have become a part of standard promotion on the majority of platforms
Why Operators Love Same Game Parlays?
These do not simply stand out as a trendy product, but they are also one of the casino games with the highest profit margins.
Built-In Margin Advantage
The sportsbooks include an extra vig on their legs above the usual odds. If there is a three-leg one game parlay placed as single bets, the winnings constituted will be more than 702. However, the same combination as a same sport parlay pays around 534. That difference goes straight to the operator.
All-Or-Nothing Structure
With every losing leg, the entire ticket is dead. Since hitting combinations of several legs is very difficult, most of these end up losing, creating an important source of income for sportsbooks.
Engagement and Retention
Individuals devote significant amounts of their time creating these as opposed to making individual wagers. The parlay creator is a retention device — players who spend more time creating a ticket are likely to be more attached to it.
Promotional Hook
Among other ways for attracting customers for gambling in regulated sports are parlays in same game insurance, higher odds, and pre-made betting tips. These can be effective in affiliate marketing as it is easy to sell and lure new players thanks to the high possible winnings as well as ready-made tickets.
What Bettors Should Know Before Placing an SGP?
Legs Should Be Limited
While constructing same game parlays, you should stick to two to three legs. If a one game parlay has five or even more legs, its hold is about 15-20%, thus making the situation where you lose on every extra leg despite good odds.
Line Shop Across Sportsbooks
Sometimes the same parlays might be priced differently on different sites. For example, you may find +650 in a sportsbook and +850 somewhere else for the same bet. Always check the odds before placing a bet.
Watch for Voided Legs
When a player does not take part in the leg, it gets cancelled, and the odds get recalculated for the remaining legs. If cancellation leads to a single-bet parlay, sportsbooks categorize it as the normal bet.
Check Correlation Restrictions
Certain combinations are either forbidden or reduced drastically with not much notice. Assemble your same sport parlay, check final odds and see if they match theoretical multiplication — a considerable drop will indicate heavy correlation adjustment.
Final Thoughts
Same game parlays represent the best innovation in the sportsbook game market in the last decade. They bring lots of engagement, high profit margins, and are an easy-to-promote product for the affiliate marketing industry.
For operators, these parlays help increase both session duration and bet amount on each ticket as long as they are paired with the right promotion. For bettors, this style gives an advantage to those who are familiar with correlations and try to minimize their number of legs.
Help Section
What is a single game parlay and how does it work in sports betting?
In these, you can combine multiple outcomes from a single game into one wager. All selections must win to get paid out on the bet. The sportsbook will factor in the connection among the outcomes during pricing.
What is the difference between a single game parlay and a traditional parlay?
A regular parlay is an easy combination of bets on different games and sports. A same game parlay consists of bets on one game. The odds for them consider the correlation between bets, while for a regular parlay they multiply as if there is no connection.
What happens if a leg of my single game parlay is voided?
If any leg is voided, which usually happens when a player does not take part, that leg will be deleted from the bet and the odds will be figured according to the other legs. When only one leg remains, most betting companies pay it out like a regular bet.
Why do single game parlay odds pay less than expected?
To account for the relationship between different legs of the same game, sportsbooks must adjust the parlay odds as outcomes from the same game are correlated in nature. This leads to certain combinations having a better probability than others. This applies regardless of the likelihood of different legs happening individually.
What is SGP+ and how is it different from a SGP?
SGP+ combines several same-game parlays of different games into one ticket. Each underlying single game parlay has its own correlation adjustment factor, but possibilities between different games are not related. It takes the same game parlay format out of the confines of a single game and spreads it across an entire slate.
