What is a round robin bet?
A round robin is a bet that automatically splits a list of selections into every possible smaller parlay of a size you choose. Pick four teams by 2s and you get six separate two-team parlays, each with its own stake, so one loss no longer sinks the entire ticket.
How does a round robin bet work?
You choose your selections and the parlay size (by 2s, by 3s, and so on). The sportsbook creates every combination of that size and treats each as its own parlay with its own stake. If you bet four picks by 2s at $10 each, that is six parlays and $60 total at risk. The more selections and the smaller the combo size, the more individual parlays you are funding.
How payouts work
- Number of parlays = the count of combinations of your chosen size (this tool counts them for you).
- Total stake = number of parlays x your stake per parlay.
- If every selection wins, every parlay cashes and you collect the full payout shown.
- If some lose, only the parlays made entirely of winners pay, which is the point: partial coverage instead of all or nothing.
Is a round robin bet worth it?
It depends. Round robins reduce the variance of a straight parlay by covering more outcomes, but you pay for that coverage with a bigger total stake, and parlays still carry more vig than straight bets. They are worth it when you genuinely like several plays and want a miss or two to be survivable. They are not a way to beat the math: the edge still comes from the price on each leg.
The Wise Guy Team way
We would rather bet a few well-priced singles than spray a round robin, but if you build one, get the best number on every leg. Across six or ten parlays, a few cents of odds per leg compounds into real money.

It lowers variance versus a straight parlay but costs more total stake and still carries parlay vig. It is useful when you like several plays and want a miss to be survivable.
Do you profit if one leg loses?
You can. Only the parlays made entirely of winning selections pay, so partial coverage can still return a profit depending on the odds.
What does "by 2s" or "by 3s" mean?
It is the size of each parlay in the round robin. By 2s makes every two-team parlay; by 3s makes every three-team parlay, and so on.
