Round robin calculator

A round robin turns your picks into every possible parlay of a given size: 4 picks by 2s are 6 parlays, by 3s 4 parlays. Enter the picks, choose the sizes and the stake per parlay (or the total), and the calculator counts the bets, the total cost and the payout, even when some picks lose.

How to use the calculator

  1. 1

    Enter your picks

    Add the odds of each pick, from 3 to 10.

  2. 2

    Choose the parlay sizes

    Select one or more sizes (by 2s, by 3s…) and the stake per parlay or for the whole round robin.

  3. 3

    Set the results

    Mark picks as won, pushed or lost to see how many parlays cash and what the round robin pays.

Worked example

4 picks at -110 (1.9091) by 3s is 4 three-leg parlays; at $10 each it costs $40. If all 4 win, every parlay pays $69.58 and the round robin $278.33. If one pick loses, 1 parlay still cashes and pays $69.58: a $29.58 profit, where a single $40 four-leg parlay would have lost everything.

Frequently asked questions

What is a round robin bet?

A set of parlays built from the same picks: every combination of the size you choose. It costs more than one parlay but still pays when some picks lose.

How many bets are in a round robin?

It depends on picks and size: 3 picks by 2s is 3 bets, 4 by 2s is 6, 5 by 3s is 10, 6 by 3s is 20. The table below and the calculator count them for you.

How much does a round robin cost?

The stake per parlay times the number of parlays. $10 on 5 picks by 2s and 3s is 10 + 10 = 20 parlays, $200 in total.

Is a round robin better than a parlay?

It reduces the risk of losing everything on one pick, at the price of a larger total stake and a smaller maximum payout. It does not remove the vig: without value in the picks, it loses over time like any parlay.

How are pushes handled in a round robin?

The pushed pick counts as 1.00 in every parlay that contains it, so those parlays are paid on their remaining legs. The calculator applies this when you mark a pick as pushed.
