The mathematics for computing the cost of Pick-3, Pick-4, Pick-5, and even Pick-6 tickets is actually fairly simple. The more complicated task is determining which horses you are going to include on these tickets and in what dollar increment you are going to make your wagers. Also, in the case of Pick-3 wagers, determining which sequence of three races is optimal for making a wager. Most tracks offer “rolling” Pick-3 wagers, meaning that you can start a Pick-3 on any race, as long as there are two more races following that race.
However, Pick-4, Pick-5, and Pick-6 opportunities exist only on a specific sequence of races that is determined by the race track. For example, many tracks offer an early Pick-4, a late Pick-4, and a single Pick-5 and/or Pick-6. If there are ten races, the early Pick-4 might be on races 2 through 5, the late Pick-4 on races 7 through 10, and a Pick-6 on races 5 through 10. You have to look at the program to determine exactly what wagers are available on each race.
