Round Robin Calculator

Work out the returns on a Round Robin: a Trixie plus three up-and-down pairs, ten bets on three selections.

A Round Robin calculator shows you the returns across all ten bets — the Trixie and the three up-and-down pairs — for every combination of results on your three selections.

What Is a Round Robin?

A Round Robin is a Trixie with up-and-down pairs added: three doubles, one treble, and three pairs of conditional bets — ten bets on three selections. The pairs are what set it apart, because they can return money even when none of the doubles land. A Trixie pays only when at least two selections win; a Round Robin covers more scenarios by adding six extra bets that run one selection at a time and, if that wins, place a stake on another from the returns.

The Round Robin is popular because it combines the appeal of a Trixie (the potentially lucrative doubles and treble when selections land together) with the insurance of the up-and-down pairs (returns when only one or two selections win). It is the smallest flag bet, because the flag family is defined by adding up-and-down pairs to a full-cover base. A Round Robin uses a Trixie as its base and three pairs to cover the gaps; a Flag (which is also called a Superflag in some jurisdictions) uses a full cover on four selections plus up-and-down pairs. The key mechanism — the up-and-down pair — is the same in both, but the Round Robin makes it accessible at a three-selection scale, with a lower outlay.

Unlike an accumulator or parlay, a Round Robin settles multiple bets independently, each according to its own combinations and logic. The Trixie section of it works like any Trixie: three doubles and a treble, settling only if at least two selections win. The up-and-down pairs work differently: each pair takes one selection, and if it wins, it automatically places a second bet on another selection from the winnings — and the reverse happens for the other leg. This dual structure is why the Round Robin can pay on scenarios the Trixie never will.

How a Round Robin Is Calculated

A Round Robin is calculated in two halves: the Trixie and the up-and-down pairs. The Trixie part is straightforward: take all possible doubles (three) and the treble from your three selections, settle each on its own, and add the returns. If none of your selections win, the Trixie returns nothing. If only one wins, the Trixie returns nothing. If two win, the Trixie returns from the one double that landed. If all three win, you get returns from all three doubles and the treble.

The up-and-down pairs work sequentially. Each pair stakes on one selection; if that selection wins, the stake is calculated at the decimal odds, and the profit (not the return) is placed as a fresh stake on the second selection. If that second selection then wins, you get another return. If it loses, the stake is consumed and the pair returns just what came from the first selection. If the first selection loses, the second is never backed and the pair returns zero. The three pairs cover each possible ordering of the three selections: Standard Liege then Charleroi, Charleroi then Antwerp, and Antwerp then Standard Liege (and the reverses of each).

Every line is settled independently and the returns are summed. This is what makes the Round Robin useful: you get paid if all three selections win (the Trixie and all pairs contribute), you get paid if two win (the one double from the Trixie plus the relevant pairs contribute), and you get paid if one wins (the pairs contribute, because one winning selection in a pair still returns its opening stake). The only losing scenario is when none of the selections win, or when you have taken the decision to void one.

What the Calculator Shows You

The calculator returns the total outlay, which is ten times your unit stake. It then returns the total amount if all three selections win, showing you the headline return. It also shows the profit by subtracting the outlay from that return. The calculator lets you mark each selection as Win, Loss or Void, so you can see what you would collect in each combination of results — if one selection voids, if one loses, and so on. The advantage of the Round Robin structure is that you can see not just the all-win return, but the returns in the many partial scenarios the Trixie and pairs separately cover.

Worked Example

Take a Round Robin on three Belgian league selections at a EUR 1.00 unit stake. The selections are Standard Liege to win at 1.70, Charleroi to win at 2.00, and Antwerp to win at 2.40. With ten bets, your total outlay is EUR 10.00.

If all three selections win, the Round Robin returns EUR 38.84, which is a profit of EUR 28.84. This profit comes from three sources: the Trixie, which settles three doubles and a treble, and the three up-and-down pairs, each of which stakes on one selection and, if it wins, funds a bet on another from the returns. When all three land, every line wins and their returns combine into that EUR 38.84 total. This is the main attraction of the Round Robin: the upside when all selections cooperate is substantial, much better than the Trixie alone.

What the 10 Bets in a Round Robin Are Made Of

A Round Robin consists of ten distinct bets: the four bets that form a Trixie and the six bets that form three up-and-down pairs.

How One Up-and-Down Pair Settles

To understand the Round Robin, you need to see how a single up-and-down pair settles. This example uses Standard Liege at 1.70 and Charleroi at 2.00, with a EUR 1.00 stake per bet (EUR 2.00 for the pair). The pair consists of two bets: one that stakes on Standard Liege then (if it wins) on Charleroi, and another that stakes on Charleroi then (if it wins) on Standard Liege.

Notice that a single winner still produces a return: if only Standard Liege wins, the pair returns EUR 0.70 from the opening stake. This is the insurance mechanism: you recover some of your outlay even when the second selection fails. If neither wins, the pair returns zero, because both opening stakes are lost.

Understanding the Up-and-Down Pair

An up-and-down pair is two bets, not one. The first stakes your unit on Standard Liege and, if that wins, automatically places the same unit on Charleroi from the returns — keeping whatever is left over. The second bet does exactly the reverse. That is why a pair can pay when only one selection wins: the opening stake has already returned more than it cost, and the leftover stays with you even though the onward bet fails.

This is fundamentally different from a double. A double stakes and multiplies: the odds compound, so if either leg loses, the entire double is zero. A pair stakes sequentially: the first leg returns a profit, and that profit funds the second leg. If the second leg loses, you keep the profit from the first and lose only what you bet on the second. The order within each pair therefore matters to the arithmetic: Standard Liege then Charleroi settles differently from Charleroi then Standard Liege, although the Round Robin includes both directions and the totals come out symmetrically across all three pairs.

This is also why a Round Robin is harder to follow by eye than a plain Trixie. The pairs introduce sequence and conditional logic. You need to think not just about which selections win, but about which combination of wins triggers which bets and in what order. The calculator handles this complexity; the key is to understand that each pair is giving you a return path that the Trixie alone could not provide.

When a Round Robin Makes Sense

A Round Robin is most useful when you have three selections you fancy but want protection against only one or two of them winning. A Trixie on the same three selections would require at least two winners to return anything; a Round Robin requires only one winner to return a modest amount through the up-and-down pairs. This protection is valuable when your confidence is high but not absolute, or when you want to cover more scenarios than a Trixie allows.

Ask yourself whether you genuinely fancy all three selections and expect at least two to win. If so, the simpler Trixie structure offers better upside on the doubles and treble at lower cost. If you are less confident or want to spread your risk across single-winner scenarios, the Round Robin’s pairs add real value by returning something when only one selection lands. The tradeoff is that the ten-bet structure costs more than the four-bet Trixie.

Bankroll management is essential. A Round Robin costs ten times your unit stake, so at a EUR 1.00 unit stake the outlay is EUR 10.00. Scale your stake to fit your bankroll; ten bets is a substantial commitment. Never force a Round Robin into a bankroll that cannot absorb the outlay comfortably. The Round Robin works best when it slots naturally into your staking plan rather than stretching you to accommodate it.

Common Mistakes

Many bettors treat an up-and-down pair as a double, forgetting that it settles in sequence and not together. Others read the unit stake as the total, forgetting that a Round Robin is ten times it. Some assume a Round Robin and a Trixie cost the same, when the pairs more than double the outlay. Finally, many overlook that a losing first leg stops the onward bet before it is ever placed, so a single loss across the pair is final.

Round Robin Against the Other Three-Selection Bets

The Round Robin, Trixie, and Patent are the three main ways to bet three selections, each offering different cost and coverage profiles.
