Parlays and round robin bets are two popular sports betting strategies, each with unique risk and reward profiles.
- Parlays: Combine multiple bets into one. All picks must win for a payout, offering high returns but high risk. A single loss voids the entire bet.
- Round Robins: Break picks into smaller parlay combinations. Even if some lose, you can still win on others. This approach lowers risk but requires a higher upfront cost and offers smaller payouts.
Quick Comparison
Feature | Parlays | Round Robins |
Win Requirement | All picks must win | Some combinations can lose |
Payout Potential | High | Lower but more consistent |
Risk Level | High | Moderate |
Cost | Low (single bet) | High (multiple combinations) |
Parlays are ideal for bettors chasing big wins with small stakes, while round robins suit those seeking more consistent returns by spreading risk. Your choice depends on your risk tolerance and betting strategy.
How Parlays Work
Parlay Structure
Parlays combine several individual bets - known as legs - into a single wager where every leg must win for the bet to pay out. It’s an all-or-nothing gamble.
For instance, imagine pairing a Kansas City Chiefs point spread, a Lakers over/under, and a Yankees moneyline. To win, all three legs must hit. If even one loses, the entire parlay fails. While the odds multiply to create the potential for massive payouts from small bets, even a single misstep means no winnings. This combination of high stakes and high rewards is what makes parlays so intriguing - and risky.
Parlay Risk and Reward
The math behind parlays explains why they’re seen as the ultimate gamble. Adding more legs increases the payout potential, but it also drastically reduces the chances of winning. For example:
- A two-leg parlay with odds of +264 gives you about a 27.44% chance of success.
- A five-leg parlay at +2436 drops that chance to just 3.94%.
- A ten-leg parlay? It plummets to a mere 0.16%, though the payout skyrockets to +64208.
These numbers highlight the razor-thin margins (for bettors) involved in parlays. Real-world examples bring this to life. During the March 2025 NCAA men’s basketball tournament, a bettor placed a $10 moneyline parlay on three underdogs: McNeese (+260 vs. Clemson), Arkansas (+180 vs. Kansas), and Drake (+210 vs. Missouri). Against the odds, all three teams pulled off wins in the first round, turning that $10 wager into $302.48.
Stories like that show why parlays are so tempting. But the reality is far less glamorous. Sportsbooks typically hold around 30% on parlays compared to just 5% on single bets. That higher house edge makes it incredibly difficult for bettors to profit consistently.
Occasionally, though, the stars align. In 2021, one bettor famously turned a $25 wager into over $100,000 by nailing a 10-leg NFL parlay. It’s the kind of story that keeps the parlay dream alive, but it’s important to remember these are rare exceptions, not the norm.
Understanding how parlays work and their inherent risks is crucial. They can transform small bets into life-changing payouts, but the odds are stacked against you. The high house edge ensures that long-term success with parlays is nearly impossible, making them a thrilling but risky addition to any betting strategy.
How Round Robin Bets Work
Round Robin Structure
Round robin bets take a different approach compared to traditional parlays. Instead of lumping all your picks into a single bet, a round robin breaks them down into smaller parlay combinations, giving you multiple chances to win while reducing your overall risk.
Here’s the gist: you start by picking three or more individual bets and then decide the size of your parlays. For example, if you choose four teams and opt for 3-team parlays, the sportsbook will create four separate 3-team combinations. Each one excludes a different team from your original four picks, ensuring every possible combination is covered.
Let’s say you’re eyeing four games: Chiefs -3.5, Lakers over 215.5, Yankees moneyline, and Celtics +7. Instead of risking it all on a single parlay, you can create a round robin with 3-team combinations. The sportsbook will generate these four separate parlays for you:
- Chiefs, Lakers, Yankees
- Chiefs, Lakers, Celtics
- Chiefs, Yankees, Celtics
- Lakers, Yankees, Celtics
Each of these combinations becomes its own parlay. If you decide to bet $50 per parlay, your total stake would be $200 ($50 × 4 combinations). The beauty here? Even if one of your picks loses, some of your parlays could still win.
You also have the flexibility to choose different parlay sizes. For the same four teams, you could create 2-team parlays instead, which would result in six combinations. Or, if you’re feeling adventurous, you could opt for an "all combinations" setup, covering every possible parlay size from your picks. Just keep in mind, the more combinations you choose, the higher your overall cost.
This structure gives you the chance to spread your bets while managing your risk - a key feature of round robin betting.
Round Robin Risk and Cost
While round robins lower your risk of losing everything, they come with a trade-off: higher upfront costs. That’s because you’re paying for every parlay combination. For instance, a 3-team round robin with $10 per 2-team parlay will cost you $30 in total. Now imagine a 5-team round robin - it generates 26 combinations, including 10 two-team parlays, 10 three-team parlays, 5 four-team parlays, and 1 five-team parlay. The costs can add up quickly.
But here’s the upside: round robins can still deliver a profit even when things don’t go perfectly. Picture this scenario: you create a 4-team, 3-way round robin and wager $50 per parlay, for a total of $200. If three of your four parlays lose, but one wins with a payout of $328.80, you’d still walk away with a $128.80 profit, despite losing $150 on the other bets.
This partial win potential is especially appealing when betting on underdogs. Instead of watching your entire parlay fall apart because one underdog didn’t deliver, you can still cash in on combinations where your other picks succeeded. It’s a less stressful approach and often a smarter play when you’re betting on higher-odds outcomes.
That said, there’s a trade-off. While round robins lower the risk of losing everything, they also limit your maximum payout compared to a traditional parlay. You’re essentially giving up the chance at a massive win in exchange for a better shot at consistent, moderate profits. This makes round robins a solid choice for bettors who frequently wager on multiple games at once.
The good news? Most sportsbooks make round robin betting straightforward. Once you add three or more selections to your bet slip, the round robin option typically appears. From there, you can pick your parlay size, see how many combinations you’re creating, and review the total cost before finalizing your bets.
Parlays vs Round Robins: Side-by-Side Comparison
Risk vs Reward
When it comes to risk and reward, parlays and round robins take very different approaches. With parlays, every single selection has to win for you to see a payout. This all-or-nothing style can lead to massive returns if everything goes your way. In contrast, round robins split your picks into smaller groups of parlays, so you can still profit even if some of your selections don’t hit.
Aspect | Parlays | Round Robins |
Win Requirement | All picks must win | Some combinations can lose and still pay out |
Maximum Payout | Higher potential return | Lower maximum payout, but steadier returns |
Risk Level | High (all-or-nothing) | Moderate (spread out risk) |
Variance | Extremely high | Much lower |
"The enemy of the parlay bettor is variance. Round Robins allow you to reduce the variance of the parlay." - Captain Jack Andrews
This contrast highlights the core difference: parlays offer the thrill of high stakes, while round robins provide a more balanced approach to managing risk and reward.
Cost and Flexibility
Round robins come with a higher upfront cost compared to parlays because you're placing multiple smaller bets instead of one single wager. A parlay only requires one stake, but a round robin demands a stake for each combination, which can add up quickly. That said, this extra cost buys you flexibility and a safety net.
"Round robin bets are a clever way to reduce exposure to a single loss. By dividing selections into multiple smaller bets, you're building a safety net that still offers upside without putting all your chips on one exact outcome." - Chris Allen, Sports & Matched Betting Expert at ProfitDuel
Another advantage of round robins is the ability to adjust your bet sizes for each combination. This lets you fine-tune your strategy, balancing risk and potential reward. Parlays, on the other hand, lock you into a single stake, leaving less room for strategic adjustments.
Which Bet Type Fits Your Style
Your betting style plays a big role in deciding between parlays and round robins. If you’re a high-risk bettor chasing massive payouts, parlays might be your go-to. They’re thrilling because every selection matters, and when you hit a big parlay, the rewards can be huge.
On the flip side, if you’re more cautious or focused on consistent returns, round robins are likely a better fit. They reduce volatility and offer a safety net, making them popular among bettors who prioritize long-term profitability. Sharp bettors often turn to round robins when they’ve identified several strong picks, trading off the chance for a huge payout for a better shot at walking away with some winnings.
For those who frequently bet on multiple games, round robins can provide more consistent results. Using tools like BettorEdge’s peer-to-peer marketplace, which offers dynamic odds and performance insights, can help you align your betting strategy with the right type of wager.

When to Choose Parlays vs Round Robins
Understanding when to use parlays versus round robins can help you balance risk and reward effectively. Here's how to decide which bet type works best for your strategy.
Best Times to Use Parlays
Parlays shine when you're confident in all your picks and want to make a focused wager with a smaller bankroll. They're especially exciting during major events like the Super Bowl or playoff games, where the stakes are high, and extensive research can boost your odds of success.
A 2-leg or 3-leg parlay is often a smarter choice than aiming for 6 or 7 legs, as the odds of hitting every selection decrease significantly with each additional pick. If you're certain about your bets and looking for a big payout, parlays can be the way to go. However, if your confidence in each selection varies, another betting approach might be more suitable.
Best Times to Use Round Robins
Round robins are ideal when you're betting on underdogs or situations with unpredictable outcomes. Their structure allows you to win even if not all your picks hit, making them a good choice when you're taking calculated risks on higher-value bets that might not consistently pay off.
If your bankroll can handle the higher upfront cost, round robins offer a more flexible approach. Since they involve multiple smaller bets, you'll pay more initially, but this setup reduces the risk of losing your entire stake. They work particularly well if you have four or more strong picks but aren't sure which ones will land. Instead of trying to guess the perfect combination, you can cover several scenarios and still walk away with a profit even if a couple of selections don't pan out.
For bettors with lower risk tolerance, round robins act as a form of "insurance." While they don't offer the massive payouts of parlays, they provide steadier returns and a better chance of coming out ahead.

Key Takeaways
When deciding between parlays and round robins, it all comes down to your risk tolerance and betting strategy. Parlays are enticing because of their high payouts, but they come with a catch: every selection in your bet must win for you to see any return. On the other hand, round robins break your selections into smaller groups of parlays. This way, even if a few picks don’t hit, you can still walk away with some profit - though it does require a larger upfront stake.
If you’re confident in all your picks and want to maximize your potential payout with a smaller investment, a parlay might be the way to go. But if you’re betting on underdogs or want to protect yourself from one bad pick ruining your chances, round robins offer a safer alternative. For example, certain round robin setups allow you to make a profit even if some of your picks don’t win. This flexibility makes them a solid choice for more cautious bettors.
Here’s a quick comparison: a $10 three-team parlay only costs $10, but a similar two-pick round robin will cost $30 ($10 per combination). While the initial investment for a round robin is higher, it reduces risk and increases your chances of seeing a return.

FAQs
How do round robin bets reduce risk compared to parlays?
Round robin bets work by splitting a larger group of selections into smaller, individual parlays. This approach reduces risk because even if one of your picks doesn’t pan out, you can still win with the remaining combinations.
Compare this to a traditional parlay, where every single selection has to hit for you to win. One wrong pick, and the entire bet is lost. Round robins, on the other hand, offer more flexibility - allowing partial payouts while still keeping the door open for potentially big wins.
What’s the difference in cost and potential payouts between round robin bets and parlays?
Round robin bets usually come with a higher upfront cost because they bundle multiple smaller wagers together. For instance, placing a $5 round robin bet on a 4-team combination would set you back $20 in total. The upside? Even if not all your picks are correct, you can still win smaller payouts, which helps minimize the risk of losing your entire stake.
Parlays, by contrast, require only a single wager, making them less expensive to start with. However, to win a parlay, every single selection must be correct - a factor that makes them riskier. The trade-off? Parlays can deliver much larger payouts if all your picks come through. In essence, round robins are better for managing risk, while parlays cater to those chasing high-reward, high-risk opportunities.
When should a bettor choose a parlay instead of a round robin, and vice versa?
A parlay is perfect for bettors who enjoy the thrill of higher stakes with the potential for a big payout. In a parlay, every single selection in your bet has to win for you to cash out. If even one pick loses, the entire wager is lost. This makes parlays attractive to those who are willing to gamble small amounts for the chance at a massive win.
On the flip side, a round robin is a safer option for those who prefer to manage their risk. It breaks your selections into smaller combinations, so you can still walk away with some winnings even if a few picks don’t hit. This method works well for bettors who value consistency and want to avoid losing everything on a single risky bet.
