❓ Frequently Asked Questions
What is a round robin bet?
A round robin is a series of smaller parlays created from a set of selections. For example, with 3 selections you can bet all possible 2‑team parlays (by 2's). It reduces risk compared to a single parlay while still offering higher payouts than straight bets.
How do I calculate a round robin payout?
First, convert American odds to decimal: positive = (odds/100)+1, negative = (100/|odds|)+1. Then generate all combinations of the chosen size, calculate the parlay payout for each (stake × product of decimal odds), and sum them. Total stake = stake × number of combinations.
What round robin sizes are available?
Common sizes include by 2's, by 3's, by 4's, etc. For example, with 4 selections, 'by 2's' creates 6 two-team parlays, while 'by 3's' creates 4 three-team parlays. Our calculator supports sizes from 2 up to the number of selections.
What is the advantage of round robin betting?
Round robins allow you to still profit even if not all selections win. For example, with a 3‑selection by 2's round robin, you can still win if two of the three selections hit. This reduces variance compared to a single 3‑team parlay.
