Add each leg's odds and your stake to see the combined parlay odds and total payout.
Multiply every leg's decimal odds together. Three legs at 2.00, 1.90 and 2.50 combine to 2.00 × 1.90 × 2.50 = 9.50.
Each leg carries the book's vig, and it compounds across legs, so the combined hold is much larger than a single bet. Parlays are high-variance.
