Higher reward, lower probability
Parlays multiply both the odds and the risk. They offer big payouts from small stakes, but the combined probability of winning falls sharply with each added leg.
Frequently asked questions
How are parlay odds calculated?
Multiply the decimal odds of every leg together. Three legs at 1.8, 2.0 and 1.5 give combined odds of 5.4, so a $10 stake returns $54.
Why are parlays risky?
Every leg must win. The payout grows fast, but so does the chance of losing, since one wrong pick loses the entire bet.
