What is Round Robin?

A bet that combines several legs into multiple smaller parlays, every possible 2-leg or 3-leg combination, instead of one big parlay.

Round robins are popular because they soften the all-or-nothing risk of a long parlay. Four legs broken into all six 2-leg parlays means a single losing leg only breaks half the tickets. The book still takes its parlay vig on every combination, so the long-run cost of a round robin is similar to that of the underlying singles plus the parlay tax.
