What a Round Robin Is
A round robin turns a set of selections into every possible combination of a given size. Pick doubles and it makes every two-selection parlay from your list; pick trebles and it makes every three-selection parlay. Each combination is a separate bet with its own stake.
The Trade-Off
The appeal is partial cover: you can still win something if one selection loses, unlike a single big parlay where one miss loses everything. The cost is that you're placing many bets, so your total stake is much larger than a single wager.
About the Max Return
The maximum return assumes every selection wins and that they all share the same odds you entered. Real returns depend on which selections win and their individual odds, so treat this figure as a best-case estimate, not a promise.
When a Round Robin Makes Sense
A round robin sits between betting singles and betting one large parlay. Instead of needing every selection to win, you cover combinations, so a single loser damages your return rather than wiping it out. That partial cover is the whole appeal.
What It Costs
You pay for that cover twice. First in stake, because you're placing many bets rather than one. Second in margin, because every combination carries the bookmaker's compounded edge on each leg inside it. The more combinations you generate, the more margin you're paying in total, which is why very wide round robins are expensive.
The Honest Comparison
If you genuinely like several selections, betting them as singles almost always produces better expected value, because you pay the margin once per selection instead of once per combination. A round robin is best understood as a way of buying a smoother set of outcomes at a known cost, not as a way of improving your edge.
