Round Robin

A round robin is a combo betting move that takes a group of three or more picks and automatically builds every possible parlay of a chosen size from them. Instead of placing one parlay that needs all your picks to win, a round robin spreads your risk across several smaller parlays. That means you can still come away with a return even if one or more of your picks loses, as long as enough of the individual parlays inside the round robin hit.

The most common round robin uses two-team parlays (also called “doubles”), but you can also build them from three-team parlays (“trebles”) or bigger combos. How many bets you end up with depends on the number of picks and the parlay size you choose. Because a round robin is made up of several individual parlays, the total stake is your per-bet stake times the number of parlays created.

Example

Say you pick three teams and build a round robin of two-team parlays with a $10 stake 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 makes 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)

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

Key Points

• Built-in loss protection: Unlike a straight parlay, a round robin can still turn a profit even when one or more picks lose, because the winning parlays may cover the losing ones.
• Higher total stake: Since you’re placing several parlays, the total wagered is much higher than a single parlay. A round robin of six picks in doubles makes 15 separate bets.
• Flexible combination sizes: You can pick the parlay size in your round robin – doubles, trebles, or bigger groups – depending on how much risk you want and how many combos you want to cover.
• Returns depend on which legs win: The overall profit or loss hinges not just on how many picks win but on which ones win, since each parlay carries different combined odds.
• Useful for confident multi-pick scenarios: Round robins shine when you like several picks but want a cushion against one or two surprise losses rather than risking it all on one big parlay.
