I struggled for quite a while as well. Just read information on what is what on the play field, learn what to shoot for, follow the little screen instructions. Do you know how to get kid multiball? Wonkavator multi, if so the next step is getting those multiball jackpots.
And one shot I always left alone was the clean shot up through the bumpers and then make the center ramp as the ball comes around to the upper right flipper. I did not even know it was a shot for 6 months. Super skill shot is a huge help on filling the candy jar and factory tours. "Candy Man" hit the three red targets, the list goes on and no bad EGG shots!!!
