Round Robin Calculator
Calculate all possible parlay combinations for your picks. Enter 3-8 legs and choose your parlay size.
What is a Round Robin?
A round robin creates every possible parlay combination from your selected picks. Unlike a straight parlay, you can still win money even if one or more picks lose.
Example: With 4 picks and 2-leg parlays, you get 6 separate 2-leg parlays. If 3 of your 4 picks win, you'll still cash 3 of your 6 parlays.

Frequently Asked Questions
What is a round robin bet?
A round robin breaks a list of selections into every possible smaller parlay combination. A 3-team round robin 'by 2s' creates three 2-team parlays, so one losing leg doesn't sink the whole ticket like a straight 3-leg parlay would.
How much does a round robin cost?
Total cost equals your unit stake times the number of combinations. Four teams by 2s is 6 parlays ($60 at $10 each); four teams by 3s is 4 parlays. The calculator shows every combination and total risk before you bet.
Is a round robin better than a straight parlay?
Round robins reduce variance - you can profit even when one leg loses - but each combination still carries compounded parlay vig. They're a middle ground between straight bets and full parlays rather than a mathematical edge.
