A round robin is only as good as its legs. Betstamp PRO surfaces +EV single bets — the legs pros actually build round robins from. See +EV Bets →
Round Robin Calculator
The Betstamp Round Robin Calculator breaks down every parlay combination in a round robin bet and calculates your total number of parlays, total stake, total payout, and profit based on actual results. Enter your stake per bet, your parlay size (2-leg, 3-leg, etc.), the odds for each leg, and mark each leg as Win, Loss, or Push — the calculator returns the exact outcome.
How to Use the Round Robin Calculator
- Enter Stake Per Bet (this is the amount per individual parlay combination, not your total stake)
- Enter Parlay Size (e.g., 2 for 2-leg round robin, 3 for 3-leg)
- Enter the odds for each leg (add as many bets as you want)
- Mark each leg as Win, Loss, or Push
- The calculator returns:
- # of Bets: total number of parlay combinations
- Total Stake: combined stake across all parlays
- Total Payout: total return based on your selected results
- Profit: net profit or loss
The Win/Loss/Push buttons for each leg let you model any outcome scenario — useful for post-game analysis or what-if modeling.
What is a Round Robin Bet?
A round robin is a series of smaller parlays built from a pool of picks. Instead of one big parlay, you split your picks into every possible smaller combination. The upside: if some picks lose, the combinations that still hit can cash. The downside: you pay more total in stakes because each combination has its own stake.
Example: Three picks — Team A, Team B, Team C. A 2-leg round robin creates three separate 2-leg parlays:
- A + B
- A + C
- B + C
Three parlays at $10 each = $30 total stake. If all three picks win, all three parlays cash. If one pick loses, only the one parlay without it wins.
How Many Parlays Does a Round Robin Create?
The number of parlay combinations depends on picks and round robin size:
- 2-leg round robin from 3 picks: 3 parlays
- 2-leg round robin from 4 picks: 6 parlays
- 3-leg round robin from 4 picks: 4 parlays
- 2-leg round robin from 5 picks: 10 parlays
- 3-leg round robin from 5 picks: 10 parlays
- 2-leg round robin from 6 picks: 15 parlays
The # of Bets output in the calculator shows this automatically based on your inputs.
Round Robin vs Straight Parlay
Use a straight parlay when:
- You're extremely confident in every pick
- You want maximum payout efficiency
- You can tolerate all-or-nothing variance
Use a round robin when:
- You want some upside even if one pick loses
- You have 3+ picks with uneven confidence levels
- You want reduced variance versus a single multi-leg parlay
Round robins have a cost. Each component parlay has its own vig, so you pay more in margin than you would for a single bigger parlay. In exchange, you get reduced swing risk.
Round Robin Strategy Tips
- Quality over quantity. A round robin on three +EV bets will outperform a round robin on six average bets every time. Use the Betstamp EV Calculator to verify each leg before building.
- Use the Win/Loss/Push buttons to model outcomes. Before placing, try different scenarios: "what if I only hit 2 of 4?" to see how the math plays out.
- Don't use round robins as a way to play more correlated legs. If your picks are correlated (same game, same team), a round robin compounds the correlation risk rather than reducing it.
Track round robin ROI separately. Round robins are structured differently enough from straight bets that mixing them in your tracker can obscure real performance.
