Most tracks only offer one or two Pick 3 opportunities per day. Some tracks offer a rolling Pick 3 , in which every race is part of a Pick 3 bet, which means that some races are included in three Pick 3 bets. In order to win a Pick 3 bet, you are required to select the winning horse in three consecutive races.
The Pick 3 Part-Wheel allows you to wager your favorite single
horses in some races and combine them with several horses in other
races.
