Quick Answer: Correlated legs cut a same game parlay’s price: $100 on four -110 legs returns $1,328.33 across four games but an illustrative $500 inside one. The $500 assumes a 16% joint chance, because correlated legs make each other more likely and the sportsbook prices them as a group. On Power.Win, you build one in the Bet Builder tab.
You stack a team to win, its quarterback over his passing yards and the game total over, all from one game. The payout comes back far below what multiplying the three prices would give. That isn’t a glitch or a stingy quote. It’s the sportsbook admitting that those picks tend to land together.
The whole difference between a same game parlay and a regular parlay is one assumption: whether the legs are independent. The $100 example, the leg-pair table and the cost figures below all come back to it.
The general mechanics (how legs multiply, what a void leg does) sit in the crypto sportsbook parlay guide, so this page sticks to correlation and price.
What is a same game parlay on a crypto sportsbook?
A same game parlay (SGP) puts two or more bets from a single event on one ticket, and every leg has to win for the ticket to pay. A traditional parlay does the same with legs from different events.
On a crypto sportsbook the bet is identical to one placed anywhere else. Only the stake and the payout are in crypto.
Power.Win’s rulebook calls it a Bet Builder: a bet on several markets of the same event, such as the total, the 1×2 result, team stats and player props. Miss one market and the whole ticket loses. Land them all and it pays your stake times the ticket’s total odds.
The “parlay” half of the name is the all-or-nothing rule. The “same game” half is what changes the price, and that’s the part worth understanding.
Why does a same game parlay pay less than the same legs across different games?
Legs from one game are correlated: when one lands, the others become more likely, so all of them landing is more probable than multiplying their separate chances suggests. The price follows that higher chance.
Take four picks that each stand at -110 on their own. A -110 price means you stake $110 to win $100. It implies a 52.4% chance (110 ÷ 210), or about 50% once you strip out the sportsbook’s margin. Treat each pick as a coin flip.
Put those four picks in four different games and nothing connects them. The chances multiply: 50% × 50% × 50% × 50% = 6.25%. The prices multiply too. At -110 a $100 stake returns $190.91, a factor of 1.909, and 1.909 to the fourth power is 13.28. A $100 ticket returns $1,328.33.
Now put four picks in one game: Team A to win, Team A’s quarterback over his passing yards, Team A’s main receiver over his receiving yards, and the game total over.
These aren’t four separate coin flips. A game where the quarterback throws for a lot is also a game where the receiver catches a lot and the total climbs, and a team that moves the ball like that is likelier to win.
Multiply the prices anyway and the ticket would pay the same $1,328.33 on a bet that lands far more often. No sportsbook can offer that, so it prices the four picks as a group.
Suppose the sportsbook’s model says all four land together in 16 of every 100 games. It adds its margin and quotes +400, which pays $500 on $100 (a $400 profit plus your stake) and implies a 20% chance.
| Same four picks, each -110 alone | Price on the ticket | $100 stake returns | Profit | Chance the price implies |
|---|---|---|---|---|
| Four different games (prices multiplied) | 13.28× (+1,228) | $1,328.33 | $1,228.33 | 7.5% |
| One game (illustrative re-price) | 5.00× (+400) | $500.00 | $400.00 | 20.0% |
| Difference | 8.28× | -$828.33 | -$828.33 | +12.5 points |
The $828.33 gap isn’t the sportsbook pocketing extra. It’s the gap between two different bets: one whose legs land together about 6% of the time, and one whose legs land together about 16% of the time. The shorter price is the fair response to the higher chance, with the sportsbook’s margin still added.
The 16% and the +400 are assumptions made for this example. Power.Win doesn’t publish Bet Builder prices, so read the numbers as the shape of the maths and not as a quote.
How do sportsbooks price correlated legs?
A sportsbook starts from each leg’s price, estimates how the legs move together, and quotes one price for the whole bet. Adding a correlated leg moves the whole price instead of multiplying one more number onto it.
The maths underneath is conditional probability. The chance of two things both happening is the chance of the first times the chance of the second, given the first.
If the legs are independent, “given the first” changes nothing and you get plain multiplication. If they’re correlated, the second chance rises once the first is assumed, and the product rises with it.
Grinstead and Snell’s probability text covers the rule in its chapter on conditional probability, and MathWorld defines it.
Here’s the four-pick game from the last section run through that rule. Each chance after the first is conditional on the legs before it. The values are made up to show the mechanism.
| Leg, in order | Chance of this leg | Running chance all legs land |
|---|---|---|
| Team A wins | 50% | 50% |
| Quarterback over his yards, given the win | 60% | 30% |
| Receiver over his yards, given both | 70% | 21% |
| Game total over, given all three | 76% | 15.96% |
| Same four picks in four different games | 50% each | 6.25% |
After the model has that joint chance of about 16%, the sportsbook adds its margin and shows a single price. That’s why you don’t see four prices multiplied together on a Bet Builder ticket. Change one leg and the model recalculates the joint chance, so the price for the whole ticket moves.
Two rules on Power.Win keep this orderly. Bet Builder legs must come from one event that carries the Bet Builder tab, and the rulebook leaves availability to the sportsbook by sport, event and market.
A regular combo is different. Rule 6.11 says that in a combo, if certain outcomes are related, “these Bets will be void.” Its example is a team winning a league and winning its deciding game.
The rule doesn’t say whether that voids the whole combo or only the related legs, so keep linked picks out of a combo and use a Bet Builder ticket where the pair is offered.
Which legs are correlated, and which only look it?
Legs are correlated when one outcome changes the odds of another, such as a team winning and its quarterback going over his yards. Legs that only sound related, like a coin toss and the final result, may not be.
Correlation can be positive (one landing makes the other likelier), negative (one landing makes the other less likely) or close to zero. Most of the legs people pair in a same game parlay are positive, which is why the price usually falls below the multiplied odds.
| Leg pair (same event) | Correlated? | Direction | Effect on the price |
|---|---|---|---|
| Team A to win + Team A quarterback over passing yards | Yes, strongly | Positive | Falls well below the multiplied odds |
| Game total over + both teams to score (football) | Yes, strongly | Positive | Falls well below the multiplied odds |
| Two opposing starters each over their points props (basketball) | Yes, moderately | Positive (a faster game lifts both) | Falls somewhat below the multiplied odds |
| Game total over + Team A under its own team total | Yes | Negative (a big total with a low Team A score needs Team B to score heavily) | Can sit above the multiplied odds, or the pair may not be offered |
| Team A wins the toss + Team A wins the match (cricket) | Weakly at most | Close to independent | Close to the multiplied odds |
Whether a pair is accepted at all is the sportsbook’s call. Bet Builder only combines markets the sportsbook offers on the tab, and a pair the model can’t price with confidence is a pair it can leave off.
Same game parlay vs traditional parlay: what actually differs?
A traditional parlay joins legs from different events and multiplies their prices. A same game parlay joins legs from one event and gets a single re-priced total. Both lose if any one leg loses.
| Feature | Traditional parlay (combo) | Same game parlay (Bet Builder) |
|---|---|---|
| Legs come from | Different events | One event that carries the Bet Builder tab |
| How the price is set | Each leg’s price multiplies | One price for the group, adjusted for correlation |
| Linked (related) legs | Rule 6.11: related outcomes “will be void”; it doesn’t say whether the whole combo or only the related legs | Same-event legs are what the feature combines, where the pair is offered |
| A void or postponed leg | Treated as odds of 1.00; the other legs set the payout | The remaining legs stand |
| Availability | Independent outcomes from different events | Not every sport, event or market; at the sportsbook’s discretion |
| Where the margin sits | In each leg’s price, compounding as legs are added | In the one combined price, on top of an estimated correlation |
| Combining the two | A combo can include other legs | A Bet Builder ticket can sit inside a combo with other legs |
Both are the same all-or-nothing bet, and both carry the sportsbook’s margin. The difference is where it sits: inside each leg’s price on a traditional parlay, and inside the single combined price on a same game parlay.
A traditional parlay fits views spread across several games. A same game parlay fits a view about the story of one game. For the leg-by-leg compounding on the traditional side, what a $100 4-team parlay pays works through a full example.
What does a same game parlay actually cost you?
The cost is the margin inside the combined price. In this page’s example, a $100 same game ticket costs about $20.00 in expected terms, against $16.98 for four -110 picks from four games and $4.55 for one -110 bet.
Expected cost is your stake minus the chance of winning times the return. Here are the three tickets with the chances stated as true chances.
- One -110 bet at a true 50%: 0.50 × $190.91 = $95.45 back on $100, so $4.55 is the cost.
- Four -110 picks in four games, each a true 50%: 6.25% × $1,328.33 = $83.02 back, so $16.98 is the cost.
- Four picks in one game, a true 16% joint chance quoted at +400: 16% × $500 = $80.00 back, so $20.00 is the cost.
Three things are worth separating.
First, the margin is invisible. You see a price, never a fee, so the only way to compare tickets is to turn the price back into a chance. +400 implies 20%, and the question is whether that is above or below the real chance of the legs landing together.
Second, the margin compounds as legs are added. Every extra leg adds another slice of margin to the price, which is why the cost climbs from $4.55 on one leg to $16.98 on four.
Third, a same game parlay’s margin sits on an estimate. The sportsbook can’t observe the correlation, it models it, so the quote reflects its model and its margin together. Power.Win doesn’t publish a margin figure for Bet Builder tickets, so no number here is a Power.Win claim.
None of this says how any single ticket will go. A ticket returns a large multiple of your stake or nothing. If the notation is new, +400 means a $100 stake profits $400, and -110 means you stake $110 to profit $100.
Building a same game parlay on Power.Win
On Power.Win, a same game parlay is a Bet Builder ticket: you combine markets from one event on that event’s Bet Builder tab, and it pays your stake times the total odds only if every market lands.
Power.Win’s docs list same-game parlays among the markets of its sportsbook, alongside spreads, totals, props, parlays and live in-play markets across football, basketball, tennis, MMA and esports.
If you’re asking which crypto sportsbooks offer same game parlays, look for three things in a book’s own published pages: same-game parlays listed among its markets, a Bet Builder-style tab on the event, and a rulebook that says what happens to a void leg.
Power.Win’s docs and rulebook cover all three, with availability still varying by sport, event and market. The rulebook gives the detail:
- What you can combine. Markets of one event, such as the total, the 1×2 result, team stats, player props and other markets marked with a Bet Builder tab.
- What isn’t promised. Bet Builder isn’t on every sport, event or market, and the sportsbook can change or remove it.
- A void leg. If one bet inside a Bet Builder ticket is voided, the remaining bets stand.
- Inside a combo. A Bet Builder ticket can be one leg of a combo with other Bet Builder tickets or regular legs.
- Early Payout. Early Payout may be available on Bet Builder tickets, at the sportsbook’s discretion.
The rulebook doesn’t spell out how a void leg re-prices the ticket, so read the slip after one.
Power.Win isn’t available to players in the United States: section 5.2 of its Terms and Conditions lists the United States of America among the countries whose players aren’t eligible to deposit or play real-money games.

Frequently Asked Questions
Four questions come up most with same game parlays: what 3+ legs means, why one leg always seems to miss, how rare a 12-leg ticket is, and whether you can cash out.
What counts as a 3+ leg same game parlay?
It means three or more selections from one game on a single ticket, and all of them have to win. Three legs at -110 multiply to 6.96 times your stake ($695.79 on $100) before any correlation adjustment, and the sportsbook’s re-price usually lowers that.
Why does every parlay lose by one leg?
It only feels that way, and the maths explains it. With four 50% legs, missing exactly one leg happens 25% of the time and hitting all four happens 6.25%, so near-misses outnumber wins four to one. Missing exactly two legs is likelier still, at 37.5%.
How rare is it to hit a 12-leg parlay?
At a true 50% per leg it’s 1 in 4,096 (0.024%). At 55% per leg it’s about 1 in 1,305, and at 60% about 1 in 459. A single miss ends the ticket, and the sportsbook’s margin means the real per-leg chances are lower than the prices suggest.
Can you cash out a same game parlay?
Sometimes. Power.Win’s docs say cash-out is available on most pre-match and live markets at the operator’s discretion, and the rulebook’s Bet Builder clause doesn’t exclude it. The offer’s value can change or be withdrawn at any moment, and it doesn’t apply to bets placed with bonus boost features.
