I picked up and Evel Knievel at the Allentown Pinfest. I have played a bunch of games and a few times, I have earned an extra ball at the spinners. From what I can see of the rules, extra balls should only come from getting all the drop targets down the second time. Are you supposed to be able to earn an extra ball through the spinners? If this is an error, any suggestions on resolving it?
