Round Robin Bet
Definition
A wager that automatically splits a group of selections into every possible smaller parlay combination, each staked separately. Not every selection has to win for the bet to return.
Key takeaways
- A round robin splits a group of selections into every possible parlay of a chosen size, each staked separately.
- Total stake is the unit stake multiplied by the number of combinations, not the unit stake alone.
- Unlike a single parlay, a round robin can still return money after one losing selection.
- UK retail sells the same structures as Trixie, Yankee, Lucky 15 and similar named multiples.
Why it matters
A round robin takes a set of selections and builds all combinations of a chosen size. Four selections in two-leg parlays produce six separate bets; the same four in three-leg parlays produce four. The bettor stakes each combination individually, so a four-by-two-leg round robin at 10 per combination is a 60 total outlay, not 10. In UK and Irish retail betting the same family of structures is sold under names such as Trixie, Yankee and Lucky 15.
The appeal is the middle ground it occupies. A straight four-fold pays well but dies on a single loss; six two-leg parlays survive one loss and still return something. The cost of that resilience is that the bettor is now paying parlay margin on every one of the six tickets, so the aggregate hold against them is higher than on four straight singles. Round robins are consequently popular with recreational customers and unpopular with anyone optimising expected value, which is exactly the shape of product a sportsbook wants on its front page.
Frequently asked questions
How much does a round robin cost?
The unit stake multiplied by the number of combinations. Four selections in two-leg parlays is six combinations, so a 10 unit stake costs 60 in total.
Is a round robin better value than a parlay?
It is more resilient, not better value. Each combination carries its own parlay margin, so the aggregate hold against the bettor is higher than on the equivalent single bets.
What is the UK equivalent of a round robin?
The named multiples: a Trixie is three selections in three doubles and a treble, a Yankee is four selections in eleven bets, and a Lucky 15 adds singles to the four-selection set.
