I really don't get the "3 to 100 hands per spin". Where does playing strategy come in on a "100 hand" spin?

The way this works is 3 -100 hands of blank cards come up. One hand where you get to pick the cards. If you hold a pair of Jacks they will show up in all the hands you play. When you hit draw the cards are then filled in on all hands. Each hand with different cards. Hope this helps. Barry
