Free parlay planning tool
Round robin bet calculator
Calculate how many component parlays a round robin creates, the total amount risked, and estimated all-win or one-loss results.
Uses equal odds for every selection to estimate ticket count and payout scenarios. Enter 2–12 selections.
The one-loss scenario assumes every other selection wins. Actual ticket odds and settlement rules can change the result.
What the result means
Use the number as an estimate
A round robin breaks a group of selections into smaller parlays of a chosen size. The number of tickets grows combinatorially, so the total risk can be much larger than the stake shown on any one ticket.
Four selections in two-leg round robins create C(4,2) = 6 tickets. At $10 per ticket, the total amount risked is $60.
