A BetMGM parlay combines two or more selections into one bet, and every leg has to win to get paid. Here is how the payout works, what to check before you place one, and how to compare it with other books.
A BetMGM parlay is a single bet that combines two or more selections (called legs), and every leg must win for the bet to pay. In exchange for that risk, the payout is much bigger than betting each leg on its own, because the odds of each leg are multiplied together. If one leg loses, the whole parlay loses. Specific rules, such as how pushes, voided legs and leg limits are handled, vary by sportsbook and by state, so always read the terms on the bet slip before you confirm.
How a parlay works on BetMGM
The mechanics are the same at most US sportsbooks. You add selections from different markets to your bet slip, and the slip gives you the option to combine them into a parlay. You enter one stake, and the app shows the combined odds and the potential payout before you confirm. The exact layout of the app changes over time, so look for the parlay option on the slip rather than relying on a screenshot-style walkthrough.
A parlay can mix different bet types, such as point spreads, moneylines and totals (over/under), and often player props too. Many books also allow legs from different sports or games in the same parlay. Which combinations are allowed differs by sportsbook and state.
How the payout is calculated
Convert each leg to decimal odds, multiply them, then multiply by your stake. Here is an invented example with round numbers, not a real line or price:
- Leg 1 is at -110, which is about 1.909 in decimal odds.
- Leg 2 is also at -110, about 1.909.
- Combined decimal odds: 1.909 x 1.909, roughly 3.645.
- A $10 stake returns about $36.45 in total, which is $26.45 profit plus your $10 back.
Add a third leg and the number grows, but so does the chance that something goes wrong. Each leg you add is another way for the whole bet to lose.
Types of parlays you may see
| Type | What it is | What to check |
|---|---|---|
| Standard parlay | Legs from different games or events combined into one bet | Maximum number of legs and how pushes are treated |
| Same game parlay | Multiple legs from one game, such as a side and a player prop | Which markets can be combined and how the price reflects correlation |
| Round robin | Several smaller parlays built from a larger set of picks | Total stake across all the combinations |
| Boosted or special parlays | Pre-built or promotional parlays, where offered | Eligibility, stake limits and terms, which change often |
Why same game parlays are priced differently
In a same game parlay the legs often influence each other. If a team scores a lot, its quarterback is also more likely to throw for a lot of yards. Because those outcomes are linked, sportsbooks do not simply multiply the individual odds the way they do for independent legs. They adjust the price for the relationship between legs. That is why a same game parlay can look different from what you get by multiplying the separate prices yourself. It is not necessarily better or worse for you, but you should not assume the math works the same way.
How to compare a BetMGM parlay with Hard Rock Bet and others
People searching for a BetMGM parlay often also check Hard Rock Bet, and that is sensible. The same parlay can be priced differently from one sportsbook to another, and a small difference in each leg compounds across the whole bet. When you compare, look at:
- The price of each leg. A half-point on a spread or a slightly better moneyline adds up over three or four legs.
- The final payout for the same stake. Compare the total return shown on the slip, not just the individual lines.
- Parlay rules. Leg limits, how a push is handled (often the leg is dropped and the parlay shrinks, but check), and what happens if a game is postponed.
- Market availability. Not every prop or same game combination is offered everywhere.
- Promotions. Bonuses and boosts change often and carry conditions. See our sportsbook bonuses page and read the terms rather than relying on headline numbers.

What are the best parlay bets?
There is no universally best parlay, and anyone promising one is selling something. What you can do is recognize the features that make a parlay more sensible than another:
- Fewer legs. Two or three legs keep the chance of hitting more realistic than eight or ten.
- Legs you have a reason for. A leg you chose because of research is better than one added just to boost the payout.
- Fair prices. Shopping around for the best price on each leg improves the value of the whole bet.
- Sensible correlation. Legs that logically support each other can make sense in a same game parlay, as long as you know the book has already priced that in.
Parlay bet strategy: a realistic approach
Parlays are high variance. Even a 52% chance on each of two legs gives you well under a 30% chance of winning both. Using the same invented -110 example, each leg has to win roughly 52.4% of the time just to break even on its own, and the break-even rate for winning both legs together is roughly 27.4%. Adding legs pushes the combined chance down quickly. With that in mind, a few habits help:
- Set a budget first. Only stake money you can afford to lose entirely, and keep parlay stakes small relative to your bankroll.
- Keep the leg count low. The more legs, the more the sportsbook's built-in margin is multiplied against you.
- Avoid mixing in "filler" legs. Adding a heavy favorite to inflate the payout slightly adds risk for a small gain.
- Compare before you place. The same bet at a better price is the easiest edge you can get.
- Never chase losses. A losing parlay is not a reason to build a bigger one. Step away if you notice yourself doing this.
No strategy guarantees profit. Sportsbooks build a margin into every price, and parlays multiply that margin, so treat them as entertainment with a defined cost.
Where you can bet
Whether you can place a parlay with BetMGM or any other sportsbook depends on the state you are physically in, and availability, age limits and taxes differ by state. Check the page for your state to see how parlay odds compare locally, for example New Jersey, Pennsylvania or Michigan, or browse all of our guides.
Frequently asked questions
What happens if one leg of my BetMGM parlay loses?
The whole parlay loses. Every leg must win for the bet to pay out. Some sportsbooks handle pushes or voided legs by removing that leg and recalculating the odds, but the rules vary, so check the terms.
Can I make a same game parlay on BetMGM?
Many sportsbooks offer same game parlays, but which markets can be combined depends on the game, the sport and your state. If you cannot add two legs together, the book usually does not allow that combination.
Is Hard Rock Bet or BetMGM better for parlays?
It depends on the specific bet. Prices, leg limits and available markets differ between books and change often, so the better option for one parlay may not be the better one for the next. Compare the total payout for the same stake before you place it.
How many legs should a parlay have?
There is no required number, and the maximum varies by sportsbook. Fewer legs mean a higher chance of winning, while each added leg lowers it. Many bettors keep parlays short for that reason.
Do bonuses apply to parlays?
Sometimes. Promotions often have conditions such as minimum odds, eligible markets or limits on stake size. Read the terms of any offer before you rely on it.
