Round Robin Formulas

The mathematics behind combination betting

Combinations Formula

C(n,r) = n! / (r! × (n-r)!)

4 selections, 2-fold: C(4,2) = 6 parlays

Parlay Odds

Total = Odds₁ × Odds₂ × ... × Oddsₙ

1.80 × 2.10 = 3.78 combined odds

Total Stake

Total = Stake × C(n,r)

$10 × 6 combinations = $60 total

Start with Doubles

2-fold combinations are safest. You only need 2 picks to win for each parlay to pay out.

Use Pro mode to see how many losses you can afford before losing money overall.

💡

Compare with Straight Parlay

Round robin costs more but protects against total loss. Calculate both to see the trade-off.

FAQ

Frequently Asked Questions

A round robin is a series of parlays created from a set of selections. Instead of one big parlay, you get multiple smaller parlays covering all possible combinations of a chosen size.
Round robin protects you from total loss if one selection fails. With a single parlay, one loss means you lose everything. With round robin, you can still profit if most selections win.
A Trixie has 3 selections creating 4 bets (3 doubles + 1 treble). A Yankee has 4 selections creating 11 bets (6 doubles + 4 trebles + 1 fourfold). More selections = more combinations.
Total stake = stake per bet × number of combinations. For example, $10 on a 4-selection 2-fold round robin: $10 × 6 combinations = $60 total stake.
Only the combinations containing that selection lose. The remaining combinations can still win. This is why round robin is less risky than a single parlay.
Round robins reduce risk but also reduce potential profit compared to a single parlay. They're profitable if your selections have positive expected value and you hit enough winners.
It depends on your confidence and risk tolerance. 2-folds (doubles) are safest but have lower payouts. Higher folds offer bigger returns but need more selections to win.

About Our Round Robin Calculator

A round robin bet is a series of parlays created from multiple selections. Instead of betting everything on one parlay where all picks must win, you spread your risk across all possible combinations of a certain size. If one selection loses, you can still profit from the remaining winning combinations.

Popular round robin formats include Trixie (3 picks), Yankee (4 picks), Canadian (5 picks), and Heinz (6 picks). Each offers different risk-reward profiles. This calculator is 100% free, works instantly, and requires no registration. Updated for 2026.
