What is a round robin bet?
A round robin is a set of smaller parlays built automatically from a list of selections you choose. Instead of putting every pick into one big parlay where a single loss kills the ticket, a round robin breaks them into every possible combination of a smaller size. Pick four teams "by 2s" and you get six separate two-team parlays. You stake each one, so some can lose and you can still profit.
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.
Frequently asked questions
What is a round robin bet?
A group of smaller parlays automatically built from your selections, so a single loss does not bust the whole ticket the way one big parlay would.
How does a round robin bet work?
You pick selections and a parlay size; the book makes every combination of that size and stakes each as its own parlay. Four picks by 2s is six parlays.
How many parlays are in a round robin?
It equals the number of combinations of your selections at the chosen size. This calculator counts them and totals your stake automatically.
Is a round robin worth it?
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.
