A round robin in sports betting is a bet comprised of parlays featuring at least two teams made up from a larger list of selections. For example, a three-selection round robin bet on Teams A, B, and C could feature three two-team parlays on Teams A and B, A and C, and B and C, as well as one three-team parlay on all three teams.
The obvious advantage to round robin betting is that it allows you to place bets with numerous selections without having to rely on a traditional multiple or parlay bet, which loses if one selection on the bet does not win.
Therefore, if you are confident of predicting the outcome of several different events, this can be a viable betting strategy that does not require an “all or nothing” approach. However, as the bet is essentially comprised of many smaller bets, the money required to stake them can very quickly increase depending on the number of selections involved.
