Round Robin

A combo bet that builds multiple parlays from a group of selections, covering different subset combinations.

A round robin takes three or more selections and automatically builds every possible parlay of a set size from them. Instead of one parlay needing all picks to win, a round robin spreads risk across several smaller parlays. You can still return a profit when one or more picks lose, as long as enough of the individual parlays win.

The common version uses two-team parlays (“doubles”), but you can also build from three-team parlays (“trebles”) or larger. The number of bets generated depends on how many selections you pick and the parlay size. Since a round robin is multiple parlays, total stake equals the per-bet stake times 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 produces three 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 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 investment, netting $3.82 profit despite one losing pick.

Key Points

  • Built-in loss protection: Unlike a straight parlay, a round robin can still profit when one or more picks lose, since winning parlays may offset the losers.
  • Higher total stake: Multiple parlays means total wagered is much higher than a single parlay. A round robin of six selections in doubles creates 15 separate bets.
  • Flexible combination sizes: Choose the parlay size — doubles, trebles, or larger — based on how much risk you want and how many combinations to cover.
  • Returns depend on which legs win: Profit or loss hinges not just on how many picks win but on which ones, since each parlay carries different combined odds.
  • Useful for confident multi-pick scenarios: Best when you like several selections but want insurance against one or two upsets rather than risking everything on one large parlay.
