Quick Answer

TL;DR summary

A round robin is multiple parlays created from a group of selections. For 3 picks in 2-team parlays, you get 3 separate parlays (AB, AC, BC). If you bet $10 per parlay, your total risk is $30. You can win some bets even if one pick loses, unlike a single parlay where all must hit.

  • You can profit even if one or more picks lose
  • Total stake = (number of parlays) × (stake per parlay)
  • Break-even requires fewer winning picks than a straight parlay
  • Popular configurations: 3 picks/2-way, 4 picks/2-way, 4 picks/3-way

Frequently Asked Questions

Common questions about round robins

What is a round robin bet?

A round robin is a betting strategy that creates multiple parlay combinations from your selections. Instead of one parlay where all picks must win, you spread risk across smaller parlays. For example, selecting 4 teams with 2-team parlays creates 6 separate parlays, giving you more chances to profit.

How many parlays does a round robin create?

The formula is "n choose k" - for n selections making k-team parlays. Common examples: 3 picks in 2-way = 3 parlays, 4 picks in 2-way = 6 parlays, 4 picks in 3-way = 4 parlays, 5 picks in 2-way = 10 parlays. The number grows quickly with more selections.

Are round robins better than regular parlays?

Round robins have lower variance - you can still profit if some picks lose. However, your total stake is higher and max payout is lower than a single parlay. They're better for managing risk, especially with 4+ selections where hitting all is unlikely.

What happens if one pick in my round robin loses?

Unlike a regular parlay, you don't lose everything. Only parlays containing that losing pick lose. For a 4-team round robin in 2-team parlays (6 total), if one pick loses, you lose 3 parlays but the other 3 can still win.

Should I use round robins for favorites or underdogs?

Round robins work well with moderate favorites (-150 to -200 range) where you expect most to win but want protection. For heavy favorites, the reduced odds make round robins less valuable. For underdogs, single parlays offer better upside.

What is the best round robin strategy?

The optimal approach depends on your confidence level. If very confident in all picks, a straight parlay maximizes profit. For moderate confidence with 4+ picks, 2-way round robins offer good balance. The 3 picks in 2-way is popular for beginners.
