Pick 3 lite uses lottery math to save you time on your workouts narrowing down the possibility of upcoming winning numbers. The hot picks provided can be used for upcoming lottery draws for up to a week, although we recommend checking them daily to find out what works best for your area. The standard rundowns are included for the pick 3 and pick 4 workouts, while the custom workouts can be used by earring coins from using the standard workouts or watching rewarded ads. There is also the option to purchase coin packs on the store page, or you can choose to purchase one of two recurring subscriptions (monthly/Yearly) which includes ad free unlimited custom workouts.
