A parlay in sports picking is a single pick that combines multiple selections or picks into one wager. To win a parlay, all the chosen selections must win. Parlays offer higher potential payouts compared to individual picks, as the odds multiply together for each added selection. However, if any of the chosen selections within the parlay loses, the entire parlay pick is typically considered lost. It's a higher-risk, higher-reward type of sports pick where success depends on the accuracy of all combined picks.
