Round robin wagers let you turn 3–8 lines into multiple parlays at once. Instead of tying all your picks into one big parlay, you spread them into smaller combinations, which means you can cash even if one leg goes sideways.
Let’s use an NFL round robin with three picks:
Dallas Cowboys -7
Green Bay Packers +3.5
Miami Dolphins -6
Instead of one three-team parlay, you set a round robin to create all possible two-team parlays:
First parlay:
Dallas Cowboys -7
Green Bay Packers +3.5
Risk $5 to win $13 (2.6/1 odds)
Second parlay:
Dallas Cowboys -7
Miami Dolphins -6
Risk $5 to win $13 (2.6/1 odds)
Third parlay:
Green Bay Packers +3.5
Miami Dolphins -6
Risk $5 to win $13 (2.6/1 odds)
Your total risk: $15
Your max return (if all three parlays win): $39
With a round robin, even hitting just one of those parlays brings money back, softening the blow compared to an all-or-nothing parlay. Stack more than three picks, and you’re not just upping the risk—you’re unlocking bigger, wilder combos. More lines, more parlays, more ways to chase that hit. The table below shows how deep you can go.
| number of lines | number of ways (parlay size) | Number of Parlays |
|---|---|---|
| 3 | 2 | 3 |
| 4 | 2 | 6 |
| 4 | 3 | 4 |
| 5 | 2 | 10 |
