What is Round Robin Betting?

Round Robin betting is a way of making ten bets in one. So here, you pick three selections that form the main part of the bet. Let’s say that it’s a weekend during the NFL season. Having studied the form of the teams playing, you’ve surmised that San Francisco, Cleveland, and Minnesota all have a good chance to win. You make a Round Robin bet on these three teams.

By making it a Round Robin bet, you have bet on San Francisco, Cleveland and Minnesota all winning as part of a treble. You’ve also bet on them all individually to win as single bets. Additionally, you’ve made three double bets: San Francisco and Cleveland to win, Cleveland and Minnesota to win, and Minnesota and San Francisco to win. So, even if one team – let’s say it’s Minnesota – lets down your treble bet, you still have some singles that have won, and you also have the San Francisco-Cleveland double paying out.

The eagle-eyed among you will have noted that this adds up to seven bets: 1x treble, 3x doubles and 3x singles. A Round Robin bet, however, has the potential to add three more singles depending on the results of the individual bets. In this case the original singles plus the bonus ones are referred to as six single bets around.

In summary:

Single Bets Around (6):Bets on one part of your selection succeeding; if it does, a bet on another part is triggered
Double Bets (3):Bets on two parts of your selection succeeding
Treble Bet (1):One bet on all of your selection succeeding

How Do Round Robins Work?

Let’s imagine you’re at one of the top sportsbooks for UFC and you’ve studied the card of an upcoming PPV. You’ve identified three fighters that you think can win on the night, so you back them as part of a Round Robin bet. We’ll call them Fighter A (odds of +200), Fighter B (+300), and Fighter C (+400). You want to place a bet that is $1 per selection – total stake $10.

Single Bets Around

Let’s go gently here, bet by bet. Fighter A is first out to the ring, and he wins! Great news! Bet 1 wins, so let’s look at what that does for your overall bet.

  • You keep the profit from the bet, so you’ve won $2. The stake is then reinvested in another bet on Fighter B. He also wins! Your return on that bet is $4, for a total return of $6.
  • Fighter B, at +300, has also won, so that’s a return of $4; $3 is profit, and $1 reinvested in Fighter A. He won, remember, so that’s another return of $6
  • Bet 3 is another bet on Fighter A with a supplementary bet on Fighter C. That’s a profit of $2, and if Fighter C wins, you return $5 for a total return of $7
  • Bet 4 is on Fighter C. She won, and your profit is $4. The supplementary bet is a winning bet on Fighter A for a return of $3, and a total of $7
  • Bet 5 is on Fighter B. Your profit of $3 is added to the return from Fighter C winning, a total of $8.
  • Bet 6 is on Fighter C. $4 profit, added to a $4 return from Fighter B winning, another $8 won.
  • So far, you’ve returned $42
Double Bets

The price of a double bet is calculated by multiplying the odds together; it’s a complicated calculation, but believe us when we say that a double on Fighters A and B is +600. A double on A and C is +800, and a double on B and C is +1200. As these bets have also come off, you are now in a position where you can add winnings of $6, $8, and $12 to your winnings, which means the double bets have returned $26, and your total winnings are now $68.

Treble Bet

Because all of the component bets have won, the treble bet is also paying out, at odds of +2400. Winnings of $24 on this treble mean that your overall winnings are $92, a handsome return on an initial bet of $10 on a perfectly reasonable outcome. This is the attraction of Round Robin betting: You don’t have to stake that much to bring back a big return if all the segments of the bet come off. But we should be clear that that is very much an “if” situation: Round Robin bets on the best betting apps are attractive, but we’ll look in the next section at why you should be careful when placing them.

The Good and The Bad 

It’s clear why this type of wagering is attractive to a lot of people using both old and new betting sites, but here is a reminder of the main pros and cons of doing trying this technique:

Advantages

A standard treble bet, while it can seem like a straightforward way to make a bigger win, is fraught with the complication that it could end up falling apart completely at the first hurdle, when the first leg of the bet loses.

By spreading the risk with a Round Robin bet, you can ensure that even when one part of the bet falls short you still get some return on it.

If the wager comes off in its entirety, moreover, you have the winnings from a treble, plus three doubles and six single bets around. That can amount to some serious winnings, if you’ve read the baseball news right and made the right selections.

Disadvantages

The returns on this type of bet can be significant, because the odds are arrived at by multiplying the probabilities together. But if you want to be really confident of a win, you’ll often need to pick very short-odds selections, and even when you multiply short odds, they stay pretty short and the returns will be surprisingly small. Then there’s the fact that you are indeed multiplying your risk and surprise results happen ‘surprisingly’ often.

Pros and Cons of Round Robins

  • Multiple Opportunities
  • Enhanced Returns
  • Risk Mitigation
  • Increased Loss Potential

Who Offers the Best Round Robin Bets in Your State?

Round robins are available across the majority of sportsbooks in the US these days. If a site isn’t offering them, they’re losing out on the opportunity and bettors may look elsewhere. There are other factors that determine where you’re best to bet though. Consider the choice of odds that are available for round robins, are some types of lines excluded from these bets or is everything available? The more lines you have to pick from and the more competitive the odds, the better any round robin returns will be.

Conclusion

The story of Round Robin betting is one of risk and reward. For sure, the reward is increased if you can get a bet to come off. That is because the risk itself is also increased. It’s a kind of wagering that we wouldn’t recommend to novice bettors who haven’t been burned by the volatility inherent to sports betting, but once you’ve got a grip on the way betting works, there is a place for Round Robin betting in your armory.

Round Robin Betting FAQ

❓ How does it differ from standard parlay bets?

Think of Round Robin betting as a souped-up version of parlay betting that not only gives you a treble bet, but a whole array of other wagers that can build into a potential windfall if everything goes right.

🎉 Is it a good way for beginners to get experience?

No, we would recommend that you don’t even try to put a Round Robin bet on until you have some experience of online betting.

🤔 What kind of return can I expect?

Like any other bet, this type of wager can be more or less impactful depending on how probable the selections in it are.
