Round Robin parlay calculator
All possible parlay combinations from N selections
Generate every possible parlay combination from your selections — a more forgiving alternative to a single big accumulator.
What is a Round Robin?
A Round Robin takes your N selections and creates parlays of every smaller size. With 4 picks, you get 6 doubles, 4 trebles, and 1 four-fold — 11 parlays total. Your total stake is N×11 (if betting 1 unit each), but losing one selection only knocks out the parlays containing it — the rest can still hit. Less variance than a single 4-leg parlay, more profit potential than 4 singles. Pairs with our Parlay calculator for single-acca payout math and Hedge calculator for in-play locking.

Example: 4-team round robin
Four picks at 1.90 each. Full round robin = 6 doubles + 4 trebles + 1 fourfold = 11 parlays at €10 each = €110 stake. If all 4 hit: full payout ~€470. If 3 of 4 hit: you still collect 3 doubles and 1 treble — about €115 (small profit). If 2 of 4 hit: 1 double pays ~€36 (€74 loss). Smoother than betting one €110 fourfold.
When to use
- Multiple value picks where you're not 100% confident on each
- Reducing variance compared to a single mega-parlay
- Big sports weekends with 4+ correlated games
