How It Works
A round robin bet creates all possible parlay combinations from your selections. For example, with 3 selections in 2-way combinations, you get 3 separate 2-team parlays.
How Round Robin is Calculated:
First, calculate the number of combinations:
Number of Bets = C(n, r) = n! / (r! × (n-r)!)
Where n = number of selections, r = combination size
Then calculate each parlay:
Parlay Odds = Odds1 × Odds2 × ... × OddsR
Parlay Payout = Stake × Parlay Odds
Total investment and potential payouts:
Total Investment = Stake × Number of Bets
Total Potential Payout = Sum of all Parlay Payouts
Example:
If you have 3 selections with odds 2.00, 1.50, 3.00 in 2-way combinations:
- Number of bets = C(3,2) = 3 bets
- Bet 1: 2.00 × 1.50 = 3.00
- Bet 2: 2.00 × 3.00 = 6.00
- Bet 3: 1.50 × 3.00 = 4.50
- If stake is $10 per bet: Total investment = $30
- If all win: Total payout = $10×3.00 + $10×6.00 + $10×4.50 = $135

How the Round Robin Calculator Works
Round robin bets create all possible parlay combinations from your selections using combinatorial mathematics.
Formula for Number of Combinations:
C(n, r) = n! / (r! × (n-r)!)
Where:
- n = Total number of selections
- r = Combination size (2, 3, or 4)
Examples:
- 3 selections, 2-way: C(3,2) = 3 bets
- 4 selections, 2-way: C(4,2) = 6 bets
- 4 selections, 3-way: C(4,3) = 4 bets
- 5 selections, 2-way: C(5,2) = 10 bets
- 5 selections, 3-way: C(5,3) = 10 bets
Parlay Calculation:
Each combination is calculated as a parlay:
Parlay Odds = Product of all odds in combination
Parlay Payout = Stake × Parlay Odds
Total Investment:
Total Investment = Stake × Number of Bets
Advantages of Round Robin:
- You can win even if not all selections win
- Multiple chances to profit from your picks
- Lower risk than a single large parlay
- Higher total investment required
Frequently Asked Questions
A round robin bet creates all possible parlay combinations from your selections. For example, 3 selections in 2-way combinations creates 3 separate 2-team parlays.
The number of bets depends on your selections and combination size. Use the formula C(n,r) = n! / (r! × (n-r)!). For example, 4 selections in 2-way combinations = 6 bets.
No! That's the advantage of round robin. You can win some bets even if not all selections win. However, you need at least r selections to win (where r is your combination size) to win any bets.
A parlay requires all selections to win. A round robin creates multiple smaller parlays, so you can win even if some selections lose, but it requires a higher total investment.
Round robin offers more chances to win but requires higher total investment. It's worth it if you're confident in most but not all of your selections, or if you want to reduce risk compared to a single large parlay.
