Stake is per combination, not the total budget. All-win return assumes every selection wins at its entered odds. Scenario return uses the selected results: losing legs lose that combination, void legs are removed, and all-void combinations refund their stake. Assumes separate events; sportsbook rules and rounding may differ. Figures are rounded estimates.

| Scenario net profit | Your scenario return minus the total amount wagered. |
How Much Does a Round Robin Cost?
The total cost depends on how many selections you make, the size of each parlay and how much you wager per combination. Here’s how many bets are created when you play every possible two-leg or three-leg combination.
| Selections | 2-leg parlays | 3-leg parlays |
|---|---|---|
| 3 | 3 | 1 |
| 4 | 6 | 4 |
| 5 | 10 | 10 |
| 6 | 15 | 20 |
| 7 | 21 | 35 |
| 8 | 28 | 56 |
For example, four selections played as six two-leg parlays at $10 each would cost $60 in total. The number of combinations grows quickly as you add more picks, so it’s worth checking the total stake before placing your bet.
Round Robin vs Regular Parlay
Both bet types combine multiple selections, but they work differently.
| Regular parlay | Round robin | |
|---|---|---|
| Number of bets | One | Multiple |
| Must every selection win? | Yes | Not necessarily |
| Can losing picks still leave winning bets? | No | Yes |
| Total cost | One stake | Stake multiplied by the number of combinations |
| Potential payout | Depends on all legs winning | Depends on which combinations win |
A round robin gives you more ways to receive a payout, but it doesn’t guarantee a profit. Depending on the odds and number of losing selections, you could still lose money even if some parlays win.
