Round Robin

A combination wager that auto-builds multiple parlays from a pool of selections, covering different subset combinations.

A round robin is a combination strategy that takes three or more selections and automatically builds every possible parlay of a chosen size from them. Instead of a single parlay demanding that all picks win, a round robin distributes risk across several smaller parlays. You can still collect a return even when one or more selections lose, provided enough of the individual parlays inside the round robin come in.

The most common form uses two-team parlays (“doubles”), but round robins can also be built from three-team parlays (“trebles”) or larger groupings. The number of bets generated depends on the count of selections and the parlay size chosen. Since a round robin is a set of separate parlays, total stake equals the per-bet stake multiplied by the number of parlays created.

Example

Say you pick three teams and build a round robin of two-team parlays at $10 per parlay:

  • Selection A: Lakers moneyline at -130 (decimal odds 1.77)
  • Selection B: Celtics -4.5 at -110 (decimal odds 1.91)
  • Selection C: Warriors moneyline at +120 (decimal odds 2.20)

A three-pick round robin of doubles yields three separate parlays:

  1. A + B (combined odds: 1.77 x 1.91 = 3.38, potential payout: $33.82)
  2. A + C (combined odds: 1.77 x 2.20 = 3.89, potential payout: $38.94)
  3. B + C (combined odds: 1.91 x 2.20 = 4.20, potential payout: $42.02)

Total stake is $30 (three parlays at $10 each). If Selections A and B win but C loses, Parlay 1 pays $33.82 while Parlays 2 and 3 lose. You collect $33.82 on a $30 outlay, netting $3.82 profit despite one losing pick.

Key Points

  • Built-in loss protection: Unlike a straight parlay, a round robin can still turn a profit when one or more selections lose, because winning parlays may offset losing ones.
  • Higher total stake: Placing multiple parlays drives the total wagered well above a single parlay. A round robin of six selections in doubles creates 15 separate bets.
  • Flexible combination sizes: Bettors choose the parlay size within the round robin — doubles, trebles, or larger groups — based on the risk they want and the combinations they want covered.
  • Returns depend on which legs win: Overall profit or loss hinges not only on how many picks win but on which specific picks win, since each parlay carries different combined odds.
  • Useful for confident multi-pick scenarios: Round robins suit a bettor who likes several selections but wants insurance against one or two surprise losses instead of risking it all on one large parlay.
