How it works
A parlay multiplies the decimal odds of each leg together. To convert American odds to decimal: positive odds like +150 become 1 + (150/100) = 2.5. Negative odds like -110 become 1 + (100/110) = 1.909.
The final payout is your stake multiplied by the combined decimal. A 2-leg parlay at -110/-110 gives 1.909 x 1.909 = 3.64x your stake, or +264 in American odds. The book's implied probability is what the line says your chances are, including their vig.
