AISportsPlaysRound Robin Calculator
Enter a pool of picks and a parlay size, and see every possible combination from that pool — each one's odds, implied probability, and payout, plus the total stake required to cover all of them. No login required.
What a round robin is
A round robin breaks a bigger pool of picks into every smaller parlay combination of a chosen size. With a pool of 4 picks and a 2-team round robin, that's 6 separate 2-team parlays covering every possible pair — instead of one all-or-nothing 4-team parlay, you're spreading the same picks across several smaller slips. It costs more total stake (one stake per combination) but softens the all-or-nothing risk of a single big parlay — if one pick loses, you can still cash the combinations that didn't include it.
How to use it
Add 3 to 8 picks with their odds, choose how big each combination should be, and set a stake per combination. The tool generates every combination of that size from your pool and shows each one's odds, probability, and payout, along with the total stake needed to place all of them.
Why this adds up fast
The number of combinations grows quickly — 8 picks in 3-team combinations is 56 separate parlays. Each one needs its own stake, so the total required stake can get large even at a small amount per combination. That tradeoff — smaller individual risk, bigger total outlay — is the real thing to weigh before using this structure.
