Round Robin Calculator
Round Robin Calculator Instructions
- Select the number of teams/legs you want in your round robin (e.g., 3, 4, 5, or more).
- Choose the parlay size (2-team parlays, 3-team parlays, etc.) that the round robin will be built from.
- Enter the odds for each selection in your preferred format (usually American, like -110 or +150).
- Input your stake per parlay(or total stake, depending on how the calculator is set up).
- Click Calculate to see:
- The number of parlays in the round robin
- Your total risk
- Estimated payouts for different win scenarios (e.g., if 2 out of 3 legs win, 3 out of 4 legs win, etc.)
- Adjust the number of teams, parlay size, or stake to find the round robin structure that fits your Colorado betting budget.
What is a Round Robin Calculator?
A round robin calculator is a tool that breaks a group of selections into every possible parlay of a specific size. The Colorado Betting Hub calculator simplifies this process by counting how many parlays you’re creating, totaling your stake, and estimating your winnings based on how many legs hit.
How Does the Round Robin Calculator Work?
The round robin calculator uses basic combinatorics and standard parlay math to show you how your bet breaks down. When you choose the number of teams and parlay size, the calculator determines how many unique parlays can be formed and multiplies that by your stake per parlay to find your total risk.
Example
3 Teams, 2-Team Parlays
You choose 3 teams: A, B, and C, and build 2-team parlays (a 3-by-2 round robin).
- Possible parlays:
- A + B
- A + C
- B + C
So:
C(3, 2) = 3 parlays
If you stake $10 per parlay, your total risk is:
- 3 parlays × $10 =$30 risk
Assume each 2-leg parlay is priced around +260 (example only)
Total Payout per winning parlay at +260:
- Profit: $10 × 2.60 = $26
- Total return: $36
If all three parlays win (all teams win):
- 3 × $36 =$108 total return
- Profit = $108 − $30 =$78
If only two of the three teams win, some parlays win and some lose; the calculator helps show that outcome so you see how much of your stake is effectively “protected.”
Round Robin Odds Profit Chart
A round robin profit chart gives you a snapshot of how your bet behaves at different structures, based on a fixed stake per parlay. This helps you compare risk and potential reward before placing the bet at a Colorado sportsbook. Below is a simple example assuming:
- Odds: all selections at -110
- Stake per parlay: $10
| Round Robin Type | Teams (N) | Parlay Size (k) | Number of Parlays | Total Risk (N Parlays × $10) | Example Max Return* |
| 3 by 2 | 3 | 2 | 3 | $30 | ≈ $108 |
| 4 by 2 | 4 | 2 | 6 | $60 | ≈ $210 |
| 4 by 3 | 4 | 3 | 4 | $40 | ≈ $220 |
| 5 by 2 | 5 | 2 | 10 | $100 | ≈ $360 |
| 5 by 3 | 5 | 3 | 10 | $100 | ≈ $550 |
*Max return assumes all teams win and odds remain around -110, with typical parlay pricing. Real returns vary by sportsbook and exact odds.
Round Robin Value and Strategies
The main purpose of this tool is to show structure, cost, and potential payout—not to tell you which bets to make. However, understanding implied risk and reward can help you use round robins more intelligently:
- Start with small sizes – 2-team or 3-team round robins are easier to manage than very large combos.
- Mind your total risk – As teams increase, parlays multiply quickly. Always check the total stake number before confirming a bet.
- Use round robins to soften variance – Compared to one big parlay, a round robin can still return something if one leg loses, depending on structure.
- Shop lines at Colorado sportsbooks – Better odds on each leg can significantly change round robin payouts.
Responsible Gambling
Round robins can involve many parlays at once, which makes it easy to underestimate your total stake. The Colorado Round Robin Calculator is designed to help you see the full risk so you can keep your betting within healthy limits.

Frequently Asked Questions
1. What does the Round Robin Calculator do?
It breaks a group of selections into all possible parlays of a chosen size, then shows how many parlays you’re creating, your total stake, and estimated payouts for different win scenarios.
2. How is a round robin different from a regular parlay?
A regular parlay is just one bet with multiple legs; if one loses, the entire bet usually loses. A round robin creates multiple smaller parlays from your selections, so you might still win money even if one leg fails, depending on the structure.
3. Can I use the calculator for different odds on each leg?
Yes. Enter the odds for each selection individually and the calculator will use them to estimate payouts for the combinations built in your round robin.
4. Does this calculator work for Colorado sportsbooks?
It’s designed around standard American odds and parlay rules used by licensed Colorado sportsbooks. Always double-check final numbers on the sportsbook bet slip before placing the wager.
5. How do I know how many parlays my round robin creates?
The calculator shows the number automatically using the combination formula C(N, k) (N choose k). You don’t need to do the math yourself.
6. Can I change stake per parlay vs. total stake?
Most round robin tools let you either set a stake per parlay or a total stake to be divided across parlays. The calculator clarifies which mode you’re using and updates total risk accordingly.
7. Are round robins always safer than parlays?
Not necessarily. While they can reduce the “all-or-nothing” nature of a single parlay, they may involve a larger total stake. That’s why checking the calculated total risk is essential.
8. Does the calculator account for sportsbook boost offers or promos?
No. It assumes standard pricing. Any boosts, profit increases, or bonuses from a Colorado sportsbook need to be checked on the sportsbook’s own slip.
9. Can I use round robins for spreads, moneylines, and totals?
Yes—round robins can be built from different market types, as long as your sportsbook allows those selections to be combined.
10. Is this tool suitable for beginners?
Yes. The calculator is especially useful for beginners who want to understand how many bets they’re actually placing in a round robin and what the true cost and potential return look like.
