Quoted from lukerp:Shoot straight up the middle with the right flipper. Ball kicks to the upper playfield, rolls down to the right inlane. Repeat. 25 boring times.
There was talk of redoing the code to fix that, but not sure how far anyone got with that. If it held over from ball to ball, that would be a big step in the right direction. Otherwise you have to cross your fingers for an "Advance to Class 6 River" mystery award.
